Labour & employmentAbility-Dependent Peer ScreeningHigh-ability original participants offered performance pay selected referrals who scored 0.371 standard deviations higher on cognitive tasks (p < 0.05), whereas low-ability participants showed no statistically significant improvement in referral performance (0.084 standard deviations) because low-ability participants could not accurately predict referral performance.RCT Labour & employmentAbility-Heterogeneous Wage ReturnsTreatment effects are significantly concentrated among lower-ability workers (interaction coefficient = -0.171, p < 0.05 for employment proportion; -0.568, p < 0.05 for log daily wages). Job seekers at the 25th ability percentile experience a 25 percentage point employment increase and an $11.01 daily wage increase, compared to a 1.5 percentage point employment decline and $2.20 wage increase for those at the 75th percentile.RCT EducationAcademic Grade-Incentivized Curriculum ComplianceTest scores averaged 4 out of 10 overall due to a 48% zero-score non-compliance rate, but active participants (excluding zero-scores) averaged 8 out of 10, demonstrating that mandatory grading secured high mastery among engaged students while highlighting ongoing compliance hurdles in EdTech.RCT EducationAcademic Remediation Inefficacy in Postsecondary PersistenceApproximately 60% of entering community college students are referred to at least one developmental/remedial course, but rigorous evaluations show developmental education programs generally fail to improve degree completion rates.Observational Study Behaviour & psychologyAction-Plan Prompts for Behavioral Search BarriersEncouraging job seekers to complete a detailed search action plan closed the gap between application intentions and actual applications, expanded the diversity of job search channels utilized, and significantly increased employment outcomes.RCT Labour & employmentActivation Program Threat EffectMandatory activation increased re-employment rates by up to 30% (p < 0.01), driven substantially by threat effects before and early in program participation, with the strongest exit spikes occurring among workers facing the longest commute times to program locations.RCT Methods & evidenceActive Tracking Attrition MitigationAttrition was maintained at 3.4% to 7.7% across most study arms (except Vadodara Year 1 at 17-18% due to communal riots), with attritor pretest scores showing no significant difference between treatment and control groups.RCT Labour & employmentActual vs. Potential Experience BiasTraditional potential experience formulas understate experience payoffs, whereas tracking actual 5-day work experience demonstrates an average daily wage increase of $3.83 to $4.19 (an approximate 80% daily wage increase, p < 0.05), which equals nearly 10 years of potential experience in non-experimental Malawian estimates.Observational Study Finance & microfinanceActuarial Margin Commercial ViabilityMean willingness-to-pay was Rs. 68.40 and median willingness-to-pay was Rs. 70.00, significantly exceeding the actuarial expected payout of Rs. 44-54, demonstrating sustainable commercial demand if administrative loading factors match standard US claims ratios (65-76%).RCT Finance & microfinanceHistorical Rainfall Moment Matching in Index Contract DesignHistorical mean daily rainfall (4.18 mm vs 4.12 mm, t = -0.11) and historical coefficient of variation (0.868 vs 0.845, t = -0.16) were statistically indistinguishable between payout and non-payout villages, confirming that 2011 payouts were driven by exogenous weather shocks rather than baseline risk differences.Observational Study Methods & evidenceCommercial Ad Platform Algorithmic Randomization ImbalanceA joint statistical test of baseline covariates rejected balance across treatment groups (p = 0.00), showing significant baseline differences for gender (-0.03 female diff, p < 0.01) and age (+0.03 old diff, p < 0.01), requiring normalized difference robustness re-estimation.RCT EducationAdministrative Algorithmic Dropout TargetingLower secondary GPA (coefficient = -0.174, p < 0.01) and standardized entrance examination scores (coefficient = -0.003, p < 0.01) accounted for 19.0% of the total variation in upper secondary completion rates.Observational Study Economics (general)Administrative Social Security Data Linkage for Earnings MeasurementAdministrative linkage secured 100% verified annual earnings histories across 13 consecutive years per individual, confirming pre-lottery earnings parallel trends between nonwinners ($15,600 to $18,000) and winners ($12,000 to $14,500) while eliminating recall measurement bias.Observational Study Policy & public sectorAdministrative Exclusion of Inactive Work Scheme BeneficiariesDigital direct deposit migration focused predominantly on recent workers, excluding former female laborers despite one-third of surveyed women having previously requested program work and 75% expressing a desire to work.Observational Study Methods & evidenceMulti-Source Administrative-Survey Data TriangulationMethodological framework integrates daily factory administrative records with individual psychometric and climate surveys; empirical findings forthcoming.RCT Behaviour & psychologyAdult Non-Cognitive Personality Trait MalleabilitySoft skills training produced a statistically significant increase in extraversion of 0.164 standard deviations (p < 0.05) in the experimental sample, as well as a 0.20 standard deviation increase in extraversion and grit (p < 0.05) in the propensity score-matched sample, with zero impact on placebo cognitive tests (arithmetic and digit span recall).RCT Labour & employmentAdvance Notification Anticipation EffectNon-notified job seekers (Group C) experienced a sharper, more abrupt increase in the exit rate to work around day 90 compared to advance-notified job seekers (Group B), confirming theoretical predictions of anticipatory behavioral smoothing; however, advance notification yielded no statistically significant difference in unconditional 365-day re-employment probabilities (68.3% for Group B vs 69.7% for Group C).RCT Methods & evidenceAdversarial Non-Stationarity Bounds in Multi-Armed BanditsProves that algorithms like the Tempered Thompson Algorithm achieve worst-case average regret on the order of $O(1/\sqrt{T})$ (up to logarithmic terms) relative to any fixed targeted assignment policy, guaranteeing robust participant welfare even under non-stationary outcome distributions.RCT EducationAdvisor-Financial Role Separation82% of EFA requests submitted were approved with an average payout of $276, while navigators maintained client rapport by participating only in application assistance rather than approval decisions.RCT EducationAffirmative Action Priority Boosts in School LotteriesFree-lunch eligible students comprised 50.6% of applicants in randomized marginal priority groups at high-performing schools compared to only 33.6% in waitlisted groups, significantly increasing low-income admission rates and counteracting strategic hedging incentives.Observational Study Labour & employmentAge-Dependent Labor Supply Reduction Near RetirementIndividuals aged 55 to 65 at the time of winning exhibit a significantly larger labor earnings reduction, with an additional MPE interaction coefficient of -0.167 (standard error 0.070), whereas individuals over 65 show no such additional reduction.Observational Study EducationAge-Graded Educational Return SensitivitySchool enrollment increased by 5.9 percentage points (p < 0.05) for older girls aged 11–17 (where baseline enrollment was only 51%), compared to a statistically insignificant 3.1 percentage point gain (p = 0.23) for younger girls aged 6–10 (where baseline enrollment was already 90%).RCT Economics (general)Agnostic Machine Learning Heterogeneity Detection in Field TrialsWhile overall average treatment effects were small and statistically insignificant (-1.4 to -2.7 percentage points, p > 0.10), generic ML inference uncovered significant treatment effect gaps between the top and bottom quintiles of 20.9 percentage points for social stigma (p = 0.009) and 12.6 percentage points for salient stigma outreach (p = 0.022).RCT Labour & employmentAlgorithmic Intermediation and Bias MitigationAlgorithmic recommendation of workers to employers improved recruit pool quality and increased overall hiring. Algorithmic writing assistance on job seekers' resumes boosted hiring probability by 8 percent. Initial hiring algorithms selected far fewer Black and Hispanic candidates, but re-engineered algorithms successfully increased demographic diversity while maintaining high hiring rates.RCT Labour & employmentAlgorithmic Resume Writing AssistanceCandidates receiving algorithmic writing assistance to fix grammatical and stylistic errors were significantly more likely to receive a job offer from an employer in their first month using the platform.RCT Labour & employmentCost-Effective ALMP InterventionsThe job application workshop generated a USD 10 per month earnings increase per worker at a one-off marginal cost of USD 18.20 per person, producing an impact-to-cost ratio that substantially exceeds conventional vocational training and cash transfer programs.RCT Labour & employmentActive Labour Market Policy Threat EffectIntensification of the policy regime increased unemployment exit rates by 20% to 40% (a 20–22% time-invariant overall increase), reducing average unemployment duration by 2.2 weeks (approximately 15%). The perceived risk of activation accounted for the job-finding increase, whereas actual program participation exhibited zero or negative direct impacts.RCT EducationAlternative Classroom Observation Rubric Sensitivity and GeneralizabilityWhile FFT was selected as the primary rubric to approximate general district implementation, alternate observation tools demonstrated comparable predictive validity when adjusted for baseline student characteristics. However, specialized subject tools (such as MQI in math and PLATO in ELA) captured distinct domain-specific instructional practices.Observational Study Behaviour & psychologyAmbiguity Aversion in Novel Financial ProductsHousehold risk aversion showed no statistically significant effect on actual insurance uptake (marginal effect = -0.00285, p > 0.10). Institutional trust in financial entities was weakly negative (marginal effect = -0.0676, p < 0.10), indicating that lack of clear understanding and product ambiguity, rather than pure risk preference, suppressed commercial demand.Observational Study Labour & employmentAnglo First-Name Signaling InefficiencyApplicants with English first names and Chinese last names received a 12.5% callback rate, which was significantly lower than applicants with full English names (15.7%, p < 0.05) and not statistically different from applicants with full Chinese names (11.3%).RCT Labour & employmentAnglo-Origin Experience ParityResumes listing only British work experience received a callback rate of 14.1%, which was not statistically significantly different from the 15.8% callback rate for Canadian-experienced control resumes (Type 0), contrasting sharply with the 5.9% callback rate for resumes listing Indian, Pakistani, or Chinese experience.Observational Study Labour & employmentAbsence of Employer Announcement EffectsOutput changes during the announcement period were statistically zero (+0.014 SDs, p=0.685), compared to a 0.109 SDs output increase (p=0.020) after cash disbursement (p-value for equality of periods = 0.008), ruling out gift exchange or employer goodwill channels.RCT Labour & employmentAnonymized Selection Mechanisms and Bias ReductionBlind auditions increased the probability that female musicians advanced from preliminary rounds and were hired by major orchestras. However, mandatory resume anonymization or hiding criminal history records generated mixed or negative unintended consequences in certain corporate screening contexts.RCT EducationAnonymous Remote Counseling via Digital PlatformsFacilitated course completion and remote interaction, contributing to a 0.11 SD increase in willingness to report sexual abuse (p < 0.05) and a 0.26 SD increase in abuse reporting attitudes (p < 0.01) six months post-intervention.RCT DevelopmentAnticipatory Human Capital and Child Nutrition InvestmentSchool enrollment for girls aged 6–17 increased by 5.0 percentage points (p < 0.01), closing about 60% of the baseline boy-girl schooling gap, while BMI-for-age z-score increased by 0.24 standard deviations (p < 0.01) for girls aged 5–15.RCT Policy & public sectorBi-Weekly Adaptive Digital Skills Training in One-Stop WindowThe intervention generated statistically significant improvements in digital skills—specifically device operation, internet browsing, and online administrative task completion—alongside small positive gains in participants' self-perceived employability (Gizatea scale), self-esteem, and life satisfaction.RCT Behaviour & psychologyAspirational Video ModelingIntegrating aspirational media into business education contributed to a 70% training participation rate among invitees and a significant increase in labor hours across trained participants four months post-intervention.RCT EducationAssessment Format Volatility in Literacy Value-Added EstimationELA value-added stability coefficients between consecutive years were only 0.350 in elementary and 0.117 in middle school, compared to 0.396 and 0.512 in math. This instability stemmed from state ELA tests relying primarily on multiple-choice reading comprehension items that fail to directly capture teacher impacts on student writing.RCT DevelopmentAsset Accumulation and Savings PersistenceParticipants increased savings or asset ownership in 9 out of 10 evaluations examining asset accumulation; in Tunisia, participants retained significantly higher home, livestock, and furniture ownership 5 years post-program despite a 5 percentage point drop in employment probability.Meta-Analysis DevelopmentAsset Wealth and Cash Liquidity DecouplingOwning big animals increases the likelihood of entering the fertilizer market (first stage coefficient = +0.064, p < 0.01) but negatively predicts the total expenditure on inorganic fertilizer among active buyers (second stage coefficient = -0.036, p < 0.05).Observational Study EducationAsymmetric Demand-Side Competitive PressureDemand response is highest for already high-performing schools serving elastic, high-SES families and minimal for low-performing schools serving inelastic, disadvantaged families. Marginal incoming students drawn by score increases have higher baseline scores than existing students, increasing educational stratification.Observational Study Behaviour & psychologyAsymmetric Migrant-Recipient Preference Divergence40% of migrant senders expressed a desire for more control over how recipient households use remittances, and 56% report instructing recipients on fund usage; however, labeling resulted in a statistically non-significant change of -0.200 log points in expenditure on migrants' priority items.RCT Firms & operationsAsymmetric Management Practice Stickiness14 out of 38 practices had a 0% drop rate once adopted (e.g., preventive machine maintenance, defect-wise recording, yarn aging monitoring), whereas visual displays and daily monitoring meetings suffered high drop rates (up to 100% dropped for displayed written procedures and 64% for daily updated visual aids).RCT Labour & employmentAsymmetric Productivity-Wage Pass-Through and Signaling BottlenecksWhile manager soft skills training increased team productivity by 5.8% and manager wages by 6%, frontline workers who achieved a 13.5% productivity gain and higher promotion rates received zero wage increase due to external signaling barriers.RCT Economics (general)Asymmetric Wealth Effect of Subsidized Index ContractsOverall insurance take-up reached 42%. In non-payout villages, labor participation differences between insured and uninsured workers were statistically zero (p > 0.10, point estimate -4.6 days), whereas in payout villages, insurance payouts (Rs. 300 to Rs. 1,200) reduced labor participation by 28.5 percentage points and days worked by 15.44 days.RCT Methods & evidenceAttanasio Selection-Bias Decomposition FrameworkVirtual-Within interaction yields a statistically significant intensive quality increase among motivated Milestone 0 completers ($\beta = 0.138, p < 0.05$ in Large-Country Sample; $\beta = 0.427, p < 0.05$ in Uganda Sample). Under the BAS assumption, this observed conditional effect serves as a strict lower bound for the true unconditional quality impact.RCT Behaviour & psychologyPhysical Marker Index of Worker AttentivenessInterim cash infusions increased worker attentiveness by 0.077 SDs overall (p=0.092) and 0.133 SDs among below-median wealth workers (p=0.037), whereas financial piece-rate increases produced no attentiveness improvement (-0.013 SDs, p=0.198).RCT EducationAttitude Decay Divergence from Knowledge RetentionStandardized attitude improvements decreased from 0.24 SD at 1 week post-course to 0.17 SD at 6 months post-course (p < 0.01), contrasting with factual knowledge gains which remained flat (0.37 SD to 0.38 SD).RCT Behaviour & psychologyAttributional Cognitive UnburdeningTreated workers receiving cash were 10 percentage points (30%) more likely to attribute negative affect to non-financial reasons (p=0.038) and 9 percentage points (62%) more likely to state reasons completely distinct from income or poverty (p=0.018).RCT EducationAttrition Independence from Assigned Treatment EffectivenessAssigned teacher effectiveness had no statistically significant impact on student state test data availability (-0.012, SE = 0.033), 4th–8th grade MET project outcome availability (-0.070, SE = 0.143), or high school MET project outcome availability (-0.077, SE = 0.144), establishing that sample attrition was independent of treatment assignment.RCT Methods & evidenceConservative Attrition Bounding and ImputationLong-run wage gains remained statistically significant and economically meaningful (>10% of control mean) across all differential attrition scenarios, retaining a positive point estimate even under the most conservative assumption of imputing a full 0.5 SD penalty to missing treated units.RCT Economics (general)Audit-Protected Performance MeasurementUnannounced third-party auditing prevented data fabrication, yielding verified performance data showing no statistically significant difference in reported visit rates between socially connected households (friends/family) and non-connected households (p = 0.439).RCT Policy & public sectorAUNA Integrated Social and Employment One-Stop ModelThe intervention increased participant engagement in vocational training and employment counseling, generated small positive gains in working days and employment intensity during the final 3 months, and significantly enhanced participant empowerment (self-perceived capacity to handle stressful situations), though it did not reduce minimum income benefit reliance.RCT Behaviour & psychologyAutonomous Motivation Enhancement via Self-Determination TheorySoft skills training generated statistically significant standardized increases in autonomous functioning and intrinsic/identified motivation of up to 0.2 standard deviations (p < 0.05), while placebo cognitive measures (timed arithmetic and digit span recall) showed zero statistically significant impact.RCT Labour & employmentAuxiliary Program DecouplingTreatment assignments yielded no statistically significant differences in ALMP participation days (group D mean = 0.056–0.080), meeting invitation frequencies (group D mean = 0.011–0.013), or vacancy referrals (group D mean = 0.031–0.054) across 90, 180, and 365 days (all p-values > 0.10).RCT EducationAverage Effect Size (AES) Quality IndexingCombining multiple peer quality indicators (mean college entrance exam scores, dropout rates, remedial programs, matriculation fees) into an AES index revealed that voucher winners attended schools with statistically significant lower observable peer quality across academic indicators.Observational Study EducationBalsakhi Remedial Education ProgramRemedial education increased average test scores in treatment schools by 0.14 standard deviations in year 1 and 0.28 standard deviations in year 2, with targeted bottom-third children gaining 0.40 standard deviations and directly assigned children gaining 0.60 standard deviations.RCT Policy & public sectorCoordinated Needs-Assessment One-Stop Model for Welfare RecipientsThe one-stop shop model significantly increased the take-up of municipal social support programs and enhanced participants' mental health, but produced no statistically significant impacts on employment status, days worked, job search ability, or take-up of employment and training programs.RCT Labour & employmentBaseline Ideological Selection Effect in Labor UptakeWomen with less traditional baseline gender attitudes exhibited significantly higher job take-up rates across all work arrangements compared to women holding more traditional baseline gender views.RCT Finance & microfinanceBaseline Income Level HeterogeneityAccess to remittance labeling significantly increased the weekly remittance probability (+1.1 percentage points, p < 0.05) and log remittance amount (+0.093, p < 0.10) for above-median income migrants, but had no statistically significant impact on below-median income migrants (+0.2 percentage points, p > 0.10).RCT DevelopmentBaseline Investment Intention Realization in MicroenterprisesCapital grant recipients invested 179.3 cedis more than control firms in their baseline-specified category at Round 3 (p < 0.10), but by Round 8, total investment flows turned negative (-378.3 cedis, p < 0.10), showing no persistent asset accumulation.RCT Firms & operationsBaseline Practice Prevalence as Persistence PredictorBaseline practice prevalence in 2008 was a statistically significant positive predictor of practice retention from 2011 to 2017 (coefficient = 0.095, p<0.05), demonstrating that standard industry practices persist while novel, advanced practices revert.RCT HealthBaseline Reciprocity Predictor of Real-World AbsenteeismHealth workers who were consistently reciprocal in the baseline Trust Game (always returning a returned-received ratio >= 1 regardless of amount received) were significantly less likely to be absent during unannounced visits (38% absence rate for high-reciprocity public workers vs. 61% for low-reciprocity workers, p < 0.05), proving that lab-in-the-field game choices mirror real-world workplace effort.RCT Finance & microfinanceBaseline Remittance Level HeterogeneityAmong migrants with below-median baseline remittances, labeling access significantly increased the probability of remitting (+1.0 percentage point, p < 0.01), weekly remittance frequency (+0.012 transfers, p < 0.01), winsorized weekly amount (+174.94 PhP, p < 0.05), and log weekly remittance amount (+0.083, p < 0.01), while showing no statistically significant effect on high-baseline remitters.RCT Labour & employmentSubstitutability of Soft Skills Training for Baseline Skill DeficitsProductivity gains were significantly higher for workers with low baseline leadership skills (-4.3 percentage point differential for high baseline leaders, p < 0.05) and those without education above primary school (-7.59 percentage point differential for higher education, p < 0.10), proving adult soft skills training acts as a substitute for baseline skill stocks.RCT Labour & employmentBaseline Work HeterogeneityLabor force participation increases across public and private sectors were largest among women who had not previously worked for MGNREGS and whose husbands held conservative gender views.RCT DevelopmentBasis Risk Demand InelasticityUnsubsidized insurance take-up is low (below 15%), but demand increases significantly to 60.2% when price subsidies reach 75%, demonstrating that spatial basis risk severely dampens demand at actuarially fair prices.Observational Study DevelopmentBasis Risk as Adoption Barrier36 out of 120 Kebeles (30%) were excluded because dominant risks were non-drought perils (frost and flooding) lacking indices, and another 35 Kebeles were dropped due to incomplete historical station rainfall records required for reinsurance pricing.Expert Theory DevelopmentBasis Risk Valuation SensitivityAssigning an insurance contract to a distant rainfall station reduced mean willingness to pay by 29.45 Rupees (p < 0.01), cutting baseline policy valuation (68.4 Rupees) roughly in half.RCT Methods & evidenceIndividualized Posterior Taste Weight Recovery via Bayes' RuleIndividual posterior weights ($\hat{\beta}_i^S$) ranged from near 0 to above 3.0 across applicants. Because measurement error ($\beta_i^S - \hat{\beta}_i^S$) is orthogonal to the posterior expectation by construction, using $\hat{\beta}_i^S$ as an instrumental variable interaction avoids classical measurement error attenuation bias.Observational Study Economics (general)Bayesian Downward Belief Revision of Infectious RiskA 10 percentage point increase in the proportion of village members learning their HIV results causes respondents to attribute 1.27 fewer total deaths to AIDS (p < 0.01) and 0.143 fewer relative deaths or illnesses to AIDS (p < 0.05).RCT Behaviour & psychologyBecker-DeGroot-Marschak Contract Valuation DisconnectMean willingness-to-pay for the real policy was Rs. 68.4 (median Rs. 70). Modifying the exit threshold increased expected payout value by Rs. 40-70 but only increased willingness-to-pay by Rs. 10.86 (p < 0.01); reducing per-mm shortfall payouts reduced expected value by Rs. 10-20 and reduced willingness-to-pay by Rs. 11.90 (p < 0.01). Introducing basis risk (distant station) halved valuation, reducing bids by Rs. 29.45 (p < 0.01).RCT Methods & evidenceOrder Independence in Field BDM ValuationMean willingness-to-pay bids were virtually identical across orderings (Real policy: Rs. 69.0 in Ordering 1 vs. Rs. 67.9 in Ordering 2; Basis risk policy: Rs. 38.9 vs. Rs. 39.1), confirming complete order independence.RCT Methods & evidenceTangible Goods Simulation for Field BDM AuctionsPractice rounds enabled successful implementation of 4-contract BDM elicitations across 1,978 rural subjects, resulting in zero instances of participants refusing to complete winning transactions.RCT Finance & microfinanceBecker-DeGroot-Marschak Contract Term MispricingRaising the exit threshold increased willingness to pay by Rs. 11 despite increasing expected payout by Rs. 40–70, whereas reducing millimeter deficit payments reduced willingness to pay by Rs. 12–13 while only lowering expected payout value by Rs. 10–20.RCT DevelopmentBecker-DeGroot-Marschak Wage Elicitation MechanismOver 60% of participants accepted low piece rates (10 MWK/unit, yielding ~70 MWK daily earnings plus 50 MWK participation fee). Ex-post refusal rates were under 3% and declined over time, confirming that workers learned and adhered to truthful wage revelation.RCT HealthAbsence of Behavioral Licensing in Sexual Health EducationTreatment students showed no statistically significant differences in sexual initiation (-0.003, p > 0.10), sexual frequency (0.212, p > 0.10), or partner count (-0.009, p > 0.10) compared to control groups, despite a 55% increase in condom voucher redemptions.RCT Crime & justicePost-Program Behavioral Persistence vs. IncapacitationIn OSC+, the bulk of the 35% violent crime arrest reduction occurred after the 7-week summer program concluded, persisting for a full year. In NYC SYEP, mortality reductions (18% drop) and incarceration reductions (10% drop) persisted across multiple post-program years.RCT Behaviour & psychologyBehavioral and Personality Supervisory ScreeningLongitudinal tracking of manager traits, workplace climate, and promotion equity comparing candidate behavioral scores against subsequent performance; findings forthcoming.RCT Labour & employmentBelief Entrenchment Cost of Search FrictionsThe job fair produced minimal direct hiring (1 hire per 12 attending firms), but the temporary reduction in meeting costs corrected underlying misperceptions, driving a 26% increase in job board visits among jobseekers within 6 weeks and a 12 percentage point increase in professional vacancy advertising by firms (p < 0.01).RCT Labour & employmentSubjective Return Belief InvariancePhone call treatment produced an effect of -1.1 percentage points on expected offer probability (p = 0.542) and +0.2 percentage points on percentage of jobs deemed desirable (p = 0.929), confirming that subjective beliefs about match quality and interview returns were unchanged by treatment.RCT Economics (general)Belief Updating Realignment from Wage TransparencyDisclosing true supervisor pay reduced the mean absolute difference between perceived supervisor pay and actual salary from 35,320 SLL in the control group to 482 SLL in the treatment group (p < 0.001), where only 30% held accurate beliefs at baseline (37% underestimated, 33% overestimated).RCT Labour & employmentVoluntary Quit Benefit SanctioningJob seekers voluntarily leaving employment or education face a strict 5-week sanction period during which no UI transfers are disbursed, defining eligibility parameters for unemployment duration tracking.Observational Study Labour & employmentEx-Post Bertrand Wage Competition in Labor SearchUnder Bertrand competition, workers with one offer receive their reservation wage while workers with multiple offers extract the full match surplus. Under full activation rollout ($\tau = 1.0$), aggregate government spending on unemployment insurance decreases, but overall social welfare decreases monotonically from 0.9315 to 0.9100 due to severe vacancy posting costs and market congestion.Expert Theory EducationBetween-School Generalizability Limit of Within-School RCTsRandom assignment was strictly bounded within individual schools, grade levels, and subjects, preventing statistical evaluation of whether teacher value-added metrics hold predictive validity for cross-school teacher transfers or district-wide comparisons.RCT DevelopmentMicroenterprise 'Big Push' Transformation and Poverty Trap TestingNeither individual nor combined "big push" treatments produced persistent profit increases; pooled stated income effects were 0.905 cedis for consulting only (p > 0.10), -45.43 cedis for capital only (p < 0.05), and -23.23 cedis for capital plus consulting (p > 0.10) relative to a control mean of 111.9 cedis.RCT Methods & evidenceBirthdate-Based Randomization DesignProduced balanced baseline demographic distributions across treatment and control groups while enabling evaluation of policy regime shifts.RCT Labour & employmentBlind Resume Masking InterventionRemoving candidate names and country-identifying headers from initial recruitment software interfaces prevents recruiters from using implicit proxy shortcuts for language ability, forcing evaluations to depend solely on verifiable competencies.Expert Theory Economics (general)BMO Recruitment Intent Survey StratificationStratifying assignment using annual recruitment survey data ensured balanced treatment-control groups across firm size tiers (73% under 26 employees) and industry sectors (42% services, 25% commerce, 28% manufacturing/construction).RCT Labour & employmentBPO Recruitment Information ShockWomen aged 18 to 24 in treatment villages were 4.6 percentage points more likely to be employed in the BPO sector and 2.4 percentage points more likely to work for pay outside the home compared to the control group.RCT Labour & employmentComparative Advantage in Brawn vs. Precision TasksWomen sort 0.76 more units per day (p < 0.01), commit 0.16 fewer errors per unit (p < 0.01), and accept reservation rates 2.3 to 3.0 MWK lower than men (p < 0.01).RCT Labour & employmentBroad-Based Wage Distribution CDF ShiftWage gains persisted consistently across all 8 post-intervention months ($1 to $6 per day increase across individual months), displaying a rightward shift of the entire daily wage CDF rather than earnings concentration among a few top earners.RCT Behaviour & psychologyBudgeting and Tracking Behavioral ChannelProposes that active interaction with labeling and weekly tracking in Padalapp improves migrant financial awareness and structured budget allocation independently of recipient compliance.Expert Theory DevelopmentBundled Credit and Business TrainingBundled programs increased short-run profits, but gains were frequently driven entirely by the financial assistance component rather than training additionality; in Uganda, male entrepreneurs receiving loans and training gained 54% higher profits, whereas female profits remained completely unchanged.RCT HealthBundled Gynecological Counseling InterventionFindings on frequency of visits, contraceptive method preferences, and overall adoption rates are ongoing and forthcoming through May 2027.RCT HealthBundled Psychiatric Care and Livelihoods AssistanceCombined PC/LA reduced depression symptoms by 0.26 standard deviations and sustained improvements post-program, proving 3.5 times more effective while costing only 5 percent more than standalone PC (US$232 versus US$221 per individual).RCT Policy & public sectorBureaucratic Implementation Capacity in Export PromotionOpening trade promotion offices in foreign markets significantly increased long-term manufacturing exports when staffed by highly skilled bureaucrats, but generated no positive export impact when less-skilled officials were assigned to manage the offices.Observational Study Firms & operationsCadence-Matched Payout ArchitectureInterim wage disbursement delivered precisely during the mid-contract lean period led to immediate 287% increases in loan repayments and 6.9% productivity gains without triggering self-control expenditure busts.Expert Theory Labour & employmentCalibrated Labor Supply Elasticity of Housing SubsidiesCalibrated utility parameters ($\mu = 0.7285$) yield an income elasticity of -0.09 and a compensated wage elasticity of 0.15.RCT Labour & employmentCandidate Pre-Screening and Filtering ServicesTreatment increased permanent vacancy creation by 24% (0.047 vacancies per firm, p < 0.01) and pre-screening service usage by 58% (3.4 percentage point increase, p < 0.01), while reducing organic jobseeker applications received directly by firms by 39% (2.67 fewer applications, p < 0.01).RCT Labour & employmentCandidate Valorization and Immersion EvaluationTreatment increased vacancies receiving jobseeker attribute marketing and evaluation services (valorization/immersion) from 0.003 to 0.007 (a 0.004 increase, p < 0.01), though overall firm baseline adoption of this specific service remained low (0.3% control mean).RCT Finance & microfinanceCapital Compounding in MicroenterprisesAn initial investment differential of 6.0% (Rs 383.9) compounded over 36 months at a net monthly return differential of 2.0% (6.0% vs 4.0%) produces a Rs 23,000 capital stock gap, matching the observed Rs 23,600 empirical difference at endline.RCT Finance & microfinanceMicroenterprise Capital Grant Induced Debt DisplacementIn the immediate months following the capital drop (Round 6), capital grant recipients significantly reduced loan take-up by 135.6 cedis (p < 0.05) relative to control firms, using cash grants to displace credit borrowing while increasing short-term Susu savings by 28.38 cedis per month in the combined group (p < 0.01).RCT DevelopmentCapital Injection Superiority Over Skills TrainingEmpirical evidence across fragile states shows minimal support for the effectiveness of skills training programs alone, demonstrating that cash and capital injections generate significantly larger and more sustained income and health impacts.Meta-Analysis Finance & microfinanceTangible Capital Surplus versus Intangible Asset Financing FrictionsProject firms made average tangible capital investments of $880,000 (median $140,000) over two years, showing that direct execution costs of management practices ($3,000) were unconstrained, whereas market-rate external consulting ($250,000) faced severe intangible asset collateralization barriers in credit markets.RCT Finance & microfinanceCARA Background Risk Portfolio DecouplingDerivation shows optimal investment $\alpha^* = \frac{1}{\gamma} [\frac{\overline{R}-\mu}{\sigma_u^2} + \frac{\overline{R}}{\sigma_e^2}]$, proving that reducing expected insurance net cost ($\mu$) or basis risk ($\sigma_u^2$) directly shifts the risk-return frontier outward and increases risky investment allocation ($\alpha^*$).Expert Theory Labour & employmentCareer Readiness and Professional Soft Skills InstructionPrograms providing integrated career readiness training achieved a 10 percentage point increase in Year 2 employment rates (70% vs. 60%, p < 0.01) and an average weekly work increase of 3.4 hours per week (a 13.9% gain, p < 0.01).RCT EducationCascade Facilitator TrainingQualitative surveys revealed that 80.0% of participating teachers found the training topics innovative and almost 100.0% expressed willingness to participate again, demonstrating institutional feasibility despite implementation delays.Observational Study Policy & public sectorFull Caseworker Discretion and System Sabotage15% of treatment caseworkers (21 out of 142) never downloaded predictions for any client, overall predictions were inspected for only 37% of jobseekers, and IV estimates confirmed that downloading predictions had no statistically significant effect on compliance rates (0.00 to -0.05 across specifications).RCT Policy & public sectorCaseworker Execution HeterogeneityStatistically significant caseworker-driven treatment effect variation among low-employability clients (F-test p-value = 0.041), indicating that individual caseworker practices moderate the re-employment impact of early integration agreements.RCT Methods & evidenceCaseworker-Level Randomization in Policy EvaluationCaseworker-level randomization successfully eliminated cross-client informational spillovers while maintaining balanced treatment and control groups across observed jobseeker demographic characteristics (passing balance tests in all regions except Geneva).RCT Labour & employmentCaseworker Meeting Intensity SuperiorityEstimated meeting intensity had a strong, statistically significant positive impact on exit rates to employment (coefficients of 0.47 in Storstrøm and 2.30 in Southern Jutland), whereas estimated program participation rates had a negative or non-significant impact (-0.51 in Storstrøm, 1.73 in Southern Jutland), proving meetings are a more effective substitute for long active programs.RCT Labour & employmentCaseworker Quality Mediated EngagementJobseekers assigned to high-quality caseworkers achieved higher baseline human capital investment index scores (9.50 vs -7.33) and received significantly more training proposals in the first quarter (88.3 vs 77.7, p < 0.01) than those assigned to low-quality caseworkers. However, financial transfer treatment effects on actual training completions did not differ significantly between high- and low-quality caseworkers (-1.36 vs +4.85, p > 0.10).RCT Finance & microfinanceCash Timing and Liquidity Mismatch in Insurance DemandDelays in marketing meant farmers had already spent cash reserves on fertilizer prior to insurance offer windows, depressing cash sales. 70% of households reported lacking sufficient income for basic needs, amplifying time-sensitive liquidity barriers.Observational Study DevelopmentCaste-Specific Restriction Threshold EffectBusiness growth effects (increased loan uptake and sales expansion) were heavily concentrated among upper-caste Hindu women facing moderate social restrictions. Training produced no significant business expansion among Muslim women facing extreme social restrictions or among scheduled-caste Hindu women who faced lower baseline social restrictions.RCT Methods & evidenceCaste-Stratified Market Penetration RandomizationGenerated exogenous cross-village coverage variation ranging from 0% to 53% for cultivators and 0% to 100% for landless laborers, with zero statistically significant correlation to village size, caste concentration, or number of castes after conditioning on eligibility shares.RCT DevelopmentCaste-Stratified Village Identification StrategyConditioning on eligibility population shares eliminates endogeneity bias, reducing correlations between insurance marketing proportions and village characteristics (such as caste concentration and total households) to statistically insignificant levels (p-values > 0.33).RCT Labour & employmentMulti-Service Gender-Focused One-Stop Shop for Unemployed MothersThe program produced statistically significant improvements in job search skills, professional competencies, personal autonomy, life satisfaction, mental health, housing conditions, social interactions, and an overall social inclusion index, as well as survey-reported increases in employment likelihood (though administrative records showed no short-term employment effect).RCT Labour & employmentCasual-Labor Field-Laboratory Screening ProxyReplicated real-world day-labor market conditions where 91 percent of participants were active labor force participants and 45 percent had made real job referrals, achieving a 72 percent return rate (N = 407 referrals) with robust experimental control over financial and screening incentives.RCT Methods & evidenceCatchment Cohort Size InstrumentThe first-stage F-statistic was 23.54 without controls and 10.32 with controls, yielding an IV elasticity estimate of household expenditure to rule-based grants of -0.946 to -1.124 (p < 0.01).Observational Study Labour & employmentCausal Wage Returns to Short-Term Work ExperienceAcquiring 5 days of short-term work experience increased average daily wages by $3.83 (representing an approximate 80% wage increase) over the 8-month follow-up period and increased subsequent employment probability by 6.8 to 8.8 percentage points.RCT EducationDose-Response Threshold in Non-Cognitive InterventionsAttending 1 to 4 CBT sessions increased 11th-grade enrollment by 7.4 percentage points (p < 0.01), while attending 5 or more sessions increased 11th-grade enrollment by 19.0 percentage points (p < 0.01) and overall student engagement by 12.1 percentage points (p < 0.01).Observational Study Firms & operationsOwner Time-Constraint Bottleneck via Centralized Decision-MakingDeveloped-country plant managers can make capital investments averaging $50,000 without higher authorization, whereas developing-country owners sign off on minor $25 purchase orders; the number of owner brothers and sons directly predicts firm size due to selective family delegation.Observational Study Labour & employmentDual Vocational Certification and Long-Term Paid Internship ModelProgram take-up was exceptionally high (86% completed training), yielding statistically significant enhancements in acquired professional competencies, participant self-efficacy, job search proactivity, motivation, and overall job search strategies compared to standard public employment services.RCT Labour & employmentMobile-App Assisted Digital Literacy and Job Search ProgramOnly Treatment 2 (which included 39 hours of digital literacy training) yielded a statistically significant positive impact on the completion of online administrative procedures, whereas none of the treatment arms improved job search skills, job search intensity, or life satisfaction.RCT Labour & employmentChild Human Capital Spillovers from Adult Mental HealthcarePsychiatric Care for depressed adults increased the child human capital investment index for children older than twelve by 0.44 standard deviations compared to the comparison group post-program, whereas impacts on children under twelve were statistically insignificant.RCT Economics (general)Childhood Non-Cognitive Skill MalleabilityTreatment led to a 0.375 standard deviation increase in belief in skill malleability in Sample A (p < 0.01) and a 0.360 standard deviation increase in Sample B (p < 0.01), accompanied by a 0.300 to 0.368 standard deviation increase in self-reported perseverance.RCT Behaviour & psychologyClarke Rational Basis Risk RejectionRisk aversion is negatively correlated with stated willingness to pay (p < 0.05) and shows no positive effect on actual uptake (marginal effect = -0.00285, p > 0.10), confirming theoretical models where basis risk reverses standard expected utility predictions.Expert Theory EducationClass Size Reduction IneffectivenessThe indirect treatment effect on non-remedial students remaining in smaller, more homogeneous classrooms was 0.133 standard deviations (statistically insignificant, with a 95% confidence interval ranging from -0.076 to 0.189).RCT Finance & microfinanceClassic Grameen Repayment ModelBorrowers under the classic model invested 6.0% less of their loan in business capital (Rs 6,142 vs Rs 6,526), had 41.0% lower weekly profits three years later (Rs 1,579 vs Rs 2,220 top-coded), and were nearly three times less likely to start new businesses (2.0% vs 4.6%).RCT EducationClassroom Grit CurriculumTreated students scored 0.28 standard deviations higher in standardized math tests (p = 0.008) and 0.13 standard deviations higher in standardized Turkish tests (p = 0.027) at follow-up, while self-reported belief in skill malleability and perseverance both increased by approximately 0.30 standard deviations (p < 0.01).RCT EducationClassroom Observation Standalone Predictive ValidityFFT classroom observation scores used as a standalone predictor yielded an IV coefficient of 0.807 (p < 0.01, SE = 0.293); while causally valid and not statistically different from 1, standalone observations exhibited roughly double the estimation error of test-based value-added measures (SE = 0.149).RCT Economics (general)Parametric Risk Transfer as Climate Change AdaptationPredicted climate change from 2010–2039 is projected to reduce major Indian crop yields by 4.5% to 9.0%, but formal risk transfer enables farmers to maintain high-yield cash crop production despite heightened rainfall variability.Expert Theory Behaviour & psychologyCoarse Categorization BiasRecruiters consistently lumped foreign-named applicants into a single lower-evaluated group based on assumed language barriers. Even when resumes explicitly listed multi-language fluency (English, French, mother tongue), active extracurricular involvement, or high-prestige backgrounds, callback rates remained suppressed at 5.9% to 11.3% compared to 15.7% for native English-named resumes.Observational Study Behaviour & psychologyCognitive Bandwidth Attentiveness RecoveryReceiving early cash increased the probability of high workplace attentiveness by 7.7 percentage points overall (a 17.1% increase compared to the comparison group). Among workers with high preexisting financial strain, high attentiveness increased by 18.6 percentage points, while lower-strain workers showed no significant change.RCT Economics (general)Selective Attention and Cognitive Barriers to Experiential LearningPrior to intervention, managers failed to notice that disorganized factory floors and unmonitored defect counts directly suppressed output, despite decades of operating experience under routine operational variation.Expert Theory EducationCognitive Triad Modeling in Non-Clinical Facilitation80.0% of interviewed teachers confirmed that cognitive triad modeling enabled effective engagement, stressing that internal reflection was safer and more effective than forced emotional disclosure.Observational Study Labour & employmentCohort Wage Gap StagnationImmigrants arriving prior to the 1970s eliminated their wage gap within 10 to 15 years. In contrast, immigrants arriving in the 1990s maintained a 25% lower median wage compared to native-born workers even after 10 to 15 years of host-country residence, despite holding substantially higher post-secondary degree completion rates.Observational Study Policy & public sectorDedicated Communal Hubs and Peer Support NetworksThe ACCEDE intervention produced a large, positive impact on household income, boosted job applications, increased participation in recruitment interviews and vocational training, and enhanced internet access, social rights navigation, and community group participation.RCT DevelopmentCommunication Cost Substitution ChannelAccess to automated in-app labeling and messaging (via free SMS, WhatsApp, or Messenger) caused a statistically significant reduction in household phone and communication expenditures (-0.344 log points, p < 0.05).RCT DevelopmentCommunity Backlash Conflict Mitigation ProtocolImplementation across 90 blocks with systematic monitoring of local community reactions following each training session to protect participant safety.RCT DevelopmentCommunity Infrastructure Amenity ValuePublic works programs generated lasting community-level productive assets—such as roads and irrigation systems—that provide structural benefits to whole communities beyond the direct monetary transfers of traditional cash programs.Meta-Analysis HealthCommunity-Based Pharmacotherapy for DepressionPsychiatric Care reduced depression symptoms by 0.14 standard deviations during treatment, but decreased participants' work time by 5.4 hours per week (a 10 percent reduction) during the intervention without increasing earnings.RCT Labour & employmentMacroeconomic Productivity-Compensation DecouplingFrom 1979 to 2018, net productivity grew by 69.6% while worker hourly compensation grew by only 11.6%. Real earnings for the top 0.1% grew by 340.7% (fifteen times faster than the bottom 90%), while earnings for the bottom 90% grew by 32.9%.Observational Study Economics (general)Compositional Selection Shift Under Zero Average Treatment EffectsProfessional stigma framing shifted applicant composition significantly, increasing the share of rich applicants by 62% (p < 0.01) and currently working applicants by 28% relative to control, despite near-zero net application growth.RCT Policy & public sectorComprehensive One-Stop Shop Social Support ModelThe one-stop shop model improved overall synthetic indicators of social inclusion, housing conditions, parental skills, family satisfaction, and community integration, while reducing child material deprivation and increasing job search intensity, though it produced no statistically significant increase in short-term employment rates or earned income.RCT EducationComprehensive Social Work Case ManagementSix-semester overall persistence increased by 25.1 percentage points (TOT, p < 0.10), while associate degree completion among enrolled women increased by 31.5 percentage points (TOT, p < 0.05).RCT EducationComputer-Assisted Learning ProgramComputer-assisted math learning increased mathematics test scores by 0.35 to 0.39 standard deviations in year 1 and 0.47 standard deviations in year 2 across all student achievement tiers.RCT Behaviour & psychologyConfidence-Independent Grit EnhancementTreatment produced zero statistically significant impact on self-confidence factors in Sample A (treatment effect = -0.010, p > 0.10) and Sample B (treatment effect = -0.104, p > 0.10), despite significantly increasing malleability beliefs (+0.36 to +0.38 SD, p < 0.01) and perseverance (+0.30 to +0.37 SD, p < 0.01).RCT Labour & employmentConstant Returns to Marginal Job Search EffortMarginal applications induced by treatment yielded a 5.87% interview probability (95% CI [4.9%, 6.9%]), which is statistically indistinguishable from the 6.29% interview probability for inframarginal control applications (p = 0.647).RCT Methods & evidenceConstruct Sensitivity Divergence in Non-Cognitive EvaluationIntention-to-treat estimates showed a statistically significant improvement of 0.165 to 0.175 standard deviations on targeted PLANEA scores (p < 0.05), compared to a statistically insignificant 0.017 to 0.027 standard deviation effect on the broad BarOn inventory.RCT Firms & operationsHigh-Cost Tailored Consulting InefficiencyConsulting increased business literacy by 0.3 questions on a 4-question quiz (0.52 standard deviations, p < 0.05), but generated an average stated income change of only 0.90 GH¢ (upper bound 95% CI of 41 GH¢ / 28% increase), which is negligible relative to the $75/hour consultant cost. Participants expressed a mean willingness-to-pay of only 5.9 GH¢ (US $4) per hour for continued consulting.RCT Economics (general)Asymmetric Information and Lemons Market Failure in Advisory Services100% of candidate firms regularly received low-quality unsolicited sales offers, leading directors to reject market-rate consulting despite an estimated 130% one-year return on investment ($325,000 annual profit increase on a $250,000 investment).Expert Theory DevelopmentSubjective Consulting Valuation and Profit Decoupling ParadoxTailors reported a willingness to pay of 5.9 cedis (US $4) per hour to continue with Ernst & Young consultants, significantly higher than 2.8 cedis per hour for other consultants (p < 0.01) and 4.2 cedis per hour for alternate training (p < 0.05), despite consulting producing zero average income gains (0.905 cedi increase, p > 0.10) and an initial 26 cedi profit drop in Round 3 (p < 0.05).RCT Crime & justiceContemporaneous Crime Reduction in At-Risk YouthSYEP participation decreases overall summer arrests by 17% and felony arrests by 23%. Among the at-risk subgroup, participation reduces summer arrests by 2.75 percentage points (a 23% drop, p < 0.10) and total arrests by 34 per 1,000 youth (a 24% drop). Convictions drop by 31% overall and 2.09 percentage points among at-risk youth (p < 0.01).RCT Crime & justiceContemporaneous Incapacitation via Program Hours AllocationArrest reductions occur exclusively during the months of July and August when SYEP is actively operating (23% drop in felony arrests and 17% overall reduction), with arrest rates returning to baseline levels immediately in September after the 25-hour work schedules terminate.RCT Economics (general)Contract Customization Risk and Advance Payment MetricsCustomization elevates transaction risk because secondhand resale value is near zero, prompting advance payment demands that remain uniform regardless of whether buyer and seller share an ethnicity.RCT Labour & employmentContract Incentive Distortion in Outsourced Placement ServicesContract payments were structured as 30% upfront fixed payment, 35% upon job placement, and 35% if employment lasted at least six months. Private providers produced significantly smaller placement impacts on the most employable job candidates and applied sanctions to inactive job seekers significantly less frequently than public services.RCT Labour & employmentContract Permanence vs. Daily Wage Trade-OffAcquiring short-term work experience increased average daily wages by $3.83 (an 80% wage increase) but resulted in a negative coefficient (-0.386, p > 0.10) on the pay frequency permanence index, indicating that wage gains were concentrated in less permanent, daily-paid positions.RCT Finance & microfinanceCorporate Debt Maturity and Risk-TakingRigid short-term debt repayment schedules in microfinance act like corporate short-term debt constraints, preventing poor micro-entrepreneurs from making illiquid, high-return investments due to liquidity-driven underinvestment incentives.Expert Theory Labour & employmentCombined Corporate Intermediation and Digital Skills TrainingTreatment 2 (combining employer intermediation with digital skills) significantly improved quality employment outcomes, increasing the probability of full-time employment, the number of full-time days worked, and overall employment intensity, while decreasing loan default rates.RCT Finance & microfinanceCost-Effective Field Information AcquisitionCollecting community information and providing truthfulness incentives adds an estimated INR 40 (US$0.70) per loan, which is substantially lower than the generated monthly returns of 24-30% (or US$11.40 extra monthly household profits) achieved by high-potential entrepreneurs.RCT Labour & employmentAsymmetric Cost-Effectiveness in Active Labor Market PoliciesThe application workshop generates a **20% long-run wage gain** at an extremely low unit cost, placing its impact-to-cost ratio near the top of documented global ALMP interventions compared to expensive multi-hundred-dollar training or cash grant schemes.RCT DevelopmentCost-Effectiveness of Market Incentive Information vs Cash TransfersThe recruiting intervention cost $12 per target individual and reduced early marriage/fertility by 5.1–5.7 percentage points with a 5.0 percentage point gain in schooling, whereas unconditional cash transfers in Malawi cost $100+ per household to reduce marriage/fertility by 6.7–7.9 percentage points with no statistically significant schooling gain.RCT Labour & employmentCounselor Match Conversion EfficiencyVacancies posted by treatment firms were significantly more likely to be filled by counselor-made matches over an 8-week period, demonstrating that caseworker pre-selection increased candidate placement efficiency despite sending fewer overall applicants.RCT Labour & employmentCounselor Match Survival VelocityCounselor match survival curves for treatment vacancies diverged from control vacancies on Day 1 (p = 0.016 log-rank test), proving that dedicated counselor pre-screening significantly accelerates successful candidate match velocity.RCT Economics (general)Counterfactual Re-Randomization InferenceGenerated exact finite-sample p-values controlling for time-varying allocation history without relying on asymptotic normality, verifying that short-term 6-week employment differences across all treatment arms had p-values well above conventional significance thresholds (p > 0.12).Expert Theory Behaviour & psychologyCovert Market Choice Experiment FramingCovert framing successfully measured baseline discrimination where control group participants sacrificed goods worth nearly twice the median daily per capita food expenditure to avoid selecting transgender workers, while eliminating experimenter demand bias.RCT Labour & employmentCredential Signal InefficiencyAdding Canadian references, official degree accreditation, or permanent resident status to foreign-experienced resumes generated point estimates near zero with no statistically significant increase in callback rates.RCT EducationCredit Accumulation Velocity AccelerationProgram participants earned 4.75 additional credits by two semesters (TOT, p < 0.10)—equivalent to 1.66 additional classes—and maintained a cumulative lead of 11.79 additional credits among female participants by six semesters (TOT, p < 0.10).RCT DevelopmentCredit Constraint Budget RelaxationEven among poor households with spending near baseline levels, 88 percent spent more than the grant amount (Rs 125/year), allowing anticipated grants to relax general budget constraints and result in a 76% private expenditure offset (elasticity of -0.21, p < 0.01).RCT Economics (general)Credit Frictions and Entrepreneurial Talent MisallocationFinancial constraints block low-capital individuals with superior managerial talent from starting new enterprises, suppressing industry productivity growth by choking off competitive reallocation.Observational Study Finance & microfinanceTraining-Induced Credit Demand ActivationBusiness training doubled borrowing among upper-caste Hindu women, increasing loan take-up by 13 percentage points (p < 0.05) from a control mean of 17%, while causing a statistically insignificant reduction in savings (-315.32 rupees), confirming that training activates credit demand rather than merely increasing capital supply.RCT Crime & justiceCrime-Type Heterogeneity in Social InterventionsOSC+ participation decreased violent crime arrests by 35% (6.4 per 100 youth), but increased property crime arrests over two years by 5.8 per 100 youth from a baseline of 12.7 (a 45% increase), while having no statistically significant effect on other nonviolent crimes.RCT DevelopmentInsurance-Induced Crop Abandonment Prevention26% of insured respondents reported that insurance awareness actively influenced them against abandoning crops (versus 7% who abandoned), and 26% reported that insurance encouraged them to plant earlier.RCT DevelopmentCash Crop Profitability & Moisture Threshold DifferentialCastor and groundnut yield positive expected profits of Rs. 2,771/ha and Rs. 2,951/ha requiring 533–625 mm of rainfall, compared to a negative profit of Rs. -212/ha for sorghum and a small profit of Rs. 141/ha for red gram requiring only 278–376 mm.Observational Study Economics (general)Cross-Community Audit Methodology for Bias DetectionStandardized multi-community audit visits successfully isolated seller pricing differences (-12% for Marwari sellers vs. +5% for Andhra sellers) and buyer-seller match effects independently of product quality or negotiation script variations.RCT Policy & public sectorCross-Country Inverse Meritocracy-Salary Gap GradientPublic sector pay progression is significantly higher in lower-GDP countries (p < 0.001), while public sector meritocracy is significantly lower in lower-GDP countries (p < 0.001), demonstrating that demotivating non-meritocratic pay gaps are structurally concentrated in developing states.Observational Study Firms &

treatment rose from 22.7% to 26.3% (16% increase), malaria etiology knowledge rose from 7.1% to 9.8% (38% increase), and water treatment behavior reached 81.2% versus 77.4% in comparison villages.RCT Economics (general)Cultivator Risk-Taking and Labor Demand VolatilityA 1 standard deviation increase in rainfall increases harvest labor demand by 3.3 days more for insured cultivators than uninsured cultivators (a 22% relative increase). A 10% increase in insured cultivators lowers drought wages by 33% at the 20th percentile of rainfall, but raises wages by 29% at the 80th percentile of rainfall.RCT DevelopmentCultivator Labor Demand SensitivityA 1 standard deviation increase in rainfall per day increases harvest labor demand by 3.3 days more for insured cultivators compared to uninsured cultivators in the same village (a 22% increase in relative demand; t-stat = 2.39).RCT DevelopmentCultivator Technology Adoption ShiftInsurance coverage leads cultivators to increase total agricultural investment expenditures by 18.6% and allocate 12.3% more land area to cash crops and high-yield variety seeds relative to uninsured control farmers.RCT Crime & justiceCumulative Disadvantage Disruption in Legal SystemsSYEP participation decreases total convictions during the program summer by 31% (0.0752 percentage points, p < 0.05) and reduces misdemeanor convictions among at-risk youth by 1.56 percentage points (a 60% relative reduction on a 2.61% base, p < 0.05).RCT EducationCumulative Multi-Year Learning GainsTwo consecutive years of remedial exposure increased math test scores by 0.612 standard deviations and total test scores by 0.407 standard deviations, significantly exceeding single-year gains.RCT EducationCurriculum-Instruction MismatchOnly 19.5% of Grade 3 children in Vadodara and 33.7% in Mumbai passed Grade 1 mathematics competencies;

RCT impact evaluation on earnings and placement is ongoing.RCT DevelopmentDelayed Monsoon Index Contract ArchitectureContract payouts triggered in 4 villages in Andhra Pradesh, dispensing tiered indemnity cash payouts of Rs. 300, Rs. 750, or Rs. 1,200 per unit purchased depending on the duration of monsoon delay.RCT Economics (general)Delayed Monsoon Onset Index Contract ArchitecturePayouts ranged from Rs. 300 (15-day delay) to Rs. 1,200 (25-day delay) per unit; 14–15% of the sample households experienced qualified payouts across 4 Andhra Pradesh villages during the 2011 Kharif season.RCT Labour & employmentDemand-Side Active Labor Market PoliciesTreatment increased permanent contract vacancy postings with the public employment agency by 24% (+0.047 vacancies per firm, p < 0.01) and total vacancy postings by 14% (+0.071 vacancies, p < 0.05).RCT EducationDemand-Side Commercial Match OptimizationCombined 10th and 11th grade dropout rates reached 7.9% in industrial vocational tracks compared to 4.0% in commercial tracks; private vouchers enabled students to transition into commercial tracks, driving a 25% increase in high school graduation rates.Observational Study DevelopmentDemand-Side Market Access PrimacySupply-side programs (microcredit, business training, consulting) generated modest firm expansion, whereas demand-side market access interventions significantly increased firm revenue, profits, product quality, and long-term employment.Review EducationDemand-Side Primacy in Female EducationProviding job market information alone increased female school enrollment by 5 percentage points (closing 60 percent of the gender gap) and significantly increased girl BMI without changing financial costs or school supply.RCT EducationDemographic Covariate Inclusion in Value-Added ModelingThe incremental component removed by controlling for student demographic characteristics yielded an IV coefficient of -0.025 (SE = 0.521), demonstrating that removing demographic variables does not significantly alter post-randomization outcome predictions, though large standard errors leave the policy trade-off statistically imprecise.RCT Labour & employmentDemographic Gender Premium in Unskilled Agricultural LaborMale agricultural workers earn a statistically significant 31.0% higher log daily wage than female workers ($\beta = 0.310, t = 9.93$), controlling for age, education, rainfall shocks, soil types, and village infrastructure.Observational Study Firms & operationsDesign-Wise Costing Accuracy and Order PrioritizationAt baseline, 0% of treatment plants used design-wise efficiency analysis for pricing decisions; implementing design-specific costing enabled plants to identify unprofitable fabric stitching patterns and drop high-defect designs from sales catalogs.RCT Crime & justiceDifferential Elasticity of Felony vs. Misdemeanor OffensesSYEP participation decreases felony arrests during the program summer by 23% (p < 0.05), whereas overall misdemeanor arrest reductions are smaller in relative magnitude (14%) and less statistically precise, indicating higher responsiveness of high-severity criminal actions to structured summer employment.RCT Finance & microfinanceDifferential Binding Constraints Across Financial Product MarketsTake-up for offered savings accounts was only ~1 percentage point (9 total individuals) and microloans near zero (2 individuals), whereas micro-insurance take-up surged by 25.1 to 28.0 percentage points (p < 0.01).RCT Labour & employmentDigital Advertising Stigma Salience AmplificationProfessional stigma ads reduced program sign-ups by 26% (-0.032 percentage points, p < 0.001) and social stigma ads reduced sign-ups by 39% (-0.047 percentage points, p < 0.001) relative to control (0.121% sign-up rate), proving low-touch ad formats amplify stigma salience.RCT EducationDigital Intervention Delivery in Remote SkillingEvaluation is ongoing with baseline phone surveys completed prior to and during COVID-19 lockdowns, and 3-month post-intervention follow-up surveys conducted via phone.RCT DevelopmentDigital Marketplace Intermediation LimitsAccess to regional digital marketplaces produced limited direct increases in revenue, profit, or worker income for small individual firms on the platform, while generating broader market gains for large intermediaries and regional consumers.RCT Labour & employmentOnline Employment Platform Navigation and Communication OffsetPlatform training significantly increased employment rates, with the largest gains observed among job seekers with low baseline communication skills who leveraged digital profiles to offset written or verbal presentation limitations.RCT Labour & employmentBundled Digital Literacy and Active Job Search TrainingThe combined digital literacy program generated statistically significant and durable improvements in digital skills, job search intensity, self-perceived employability, and life satisfaction persisting 6 months post-intervention, whereas hardware provision alone yielded substantially smaller effects and neither treatment significantly increased short-term employment rates.RCT Labour & employmentDigital Soft Skills Screening and TrainingEvaluation ongoing with results forthcoming; tracking manager traits, hiring rates, retention, line productivity, and promotion equity across a 3-month module timeline.RCT DevelopmentDirect Deposit Account Linkage and Wage ControlPrior to intervention, women completed 42% of public workdays, but 75% of surveyed women desired work and struggled with direct deposit linkages, prompting an evaluation of wage control impacts on decision-making and family planning.RCT Labour & employmentFinancial Stipends and Wraparound Necessity SupportFinancial support enabled high training completion; YearUp provided full-time weekly stipends yielding 3-year earnings increases of $7,011 (a 40% increase, p < 0.01), while Project QUEST paid 100% of tuition, fees, and emergency assistance, resulting in sustained 11-year earnings increases of $4,616 (a 15% increase, p < 0.01).RCT Labour & employmentDirect Monetary Registration GrantsDirect monetary transfers equivalent to one or two months of median business profit significantly increased firm formalization rates, whereas informational talks produced zero impact.RCT DevelopmentDisaggregated Pesticide Investment SensitivityPesticide was the sole disaggregated input with a statistically significant positive response to insurance provision (marginal effect on adoption probability = 0.054, p < 0.05; log expenditure marginal effect = 0.932, p < 0.05), while other inputs showed positive but statistically insignificant coefficients.RCT EducationDisbursement Timing Liquidity IncentivesStandard periodic attendance subsidies increased secondary school attendance by 2 to 4 percentage points, whereas lump-sum payments timed at matriculation deadlines increased tertiary education attendance by over 9 percentage points.RCT EducationDiscontinuity Assignment IdentificationRD estimates confirmed that direct learning gains for tutored students approached 1.00 standard deviation, while untutored peers above the rank cutoff showed no statistically significant indirect benefits.RCT Labour & employmentDiscontinuous Skill Certification EffectBeing placed in a higher performance band generated a wage increase of 0.322 standard deviations at twice the optimal bandwidth (p < 0.10) and 0.332 standard deviations at the optimal bandwidth (p = 0.13).RCT Labour & employmentDisplacement Externalities in Active Labor Market ProgramsMandatory job search assistance increased participant exit rates from unemployment by 17.9% to 20% (p < 0.01), but reduced nonparticipant exit rates by 4.8% to 5.0% overall (p < 0.10) and by 7.9% in South Jutland (p < 0.05). At three months, nonparticipants were 2.7 percentage points less likely to find employment (p < 0.05).RCT Labour & employmentDisplacement-Free Social Network Spillover BoundariesLocal treatment saturation within 300m cluster boundaries produced zero localized job displacement; because workers commute across the integrated urban market, peer spillovers operate via social network information sharing rather than localized zero-sum job reallocation.RCT Labour & employmentDistributional Wage CDF ShiftDaily wage gains reflect a uniform rightward shift in the overall earnings distribution for individuals receiving job opportunities, proving that the $3.83 to $4.19 daily wage increase (p < 0.05) represents broad-based income growth rather than outlier-driven mean distortions.RCT EducationDistrict-Level Structural Heterogeneity in Experimental ComplianceFirst-stage compliance coefficients ranged from 0.744 in Dallas and 0.517 in Charlotte-Mecklenburg down to 0.157 in New York and -0.079 (non-significant) in Denver. Low compliance in Denver stemmed from structural language certification rules requiring Spanish-speaking students to remain with Spanish-certified teachers.RCT Labour & employmentDisutility of Leisure and Wage Discipline EffectMandatory participation eliminates non-market leisure time value ($h = 0.013$, equivalent to ~2% of UI benefit levels or >1% of worker productivity), disciplining worker outside options and lowering equilibrium wages by 0.03%, which encourages firms to expand overall vacancy postings by 2.4%.RCT Labour & employmentDominated Penalty ContractsRigid firm-imposed target penalties caused workers to miss targets 8.6% to 14.1% of the time without increasing net earnings, whereas voluntary target selection reduced the target miss rate to 2.6% and increased net worker earnings by 3%.RCT Economics (general)Double-Blind Management Scoring Methodology (BVR Framework)Baseline BVR management practice scores correlated at 0.404 (p = 0.077) with the paper's 38 binary practice index across experimental firms, successfully capturing systematic productivity differences across countries and firms.Observational Study Economics (general)Double Post-Lasso High-Dimensional Covariate SelectionThe automated procedure selected only 4 baseline variables out of 43 (prior vacancies, prior permanent hires, prior fixed-term hires, and sector indicators), yielding identical treatment effect point estimates (+0.047 for permanent hires) and standard errors (0.022).RCT Labour & employmentDouble-Sided Randomization DesignPlacing 1.398 formal apprentices per firm displaced only 0.318 traditional apprentices, creating a net gain of 1.080 total apprentices per firm (p < 0.0001); net job creation was bounded between 74.1% and 77.3% of formal positions placed.RCT DevelopmentDownstream Household Welfare Invariance to Short-Term Financial Capability InterventionsNo statistically significant impacts were detected across any of the 8 categorical welfare indices (all q-values ≥ 0.240), and the combined intervention showed no differential effect compared to individual treatments (p-value for T1+T2=T3 ranged from 0.268 to 0.969).RCT Labour & employmentDriver's License Asset Accrual in Youth MobilityOut of all measured human capital investment components, driver's license course enrollment was the only specific outcome significantly increased by cash transfers, rising by 3.0 percentage points (p < 0.05) from a control mean of 41.9% at 12 months, with automobile usage rising to 55.4% by 24 months (p < 0.05).RCT Labour & employmentDual-Barrier Hiring FrictionsProviding promotional advertising alone doubled applicants per vacancy from 25 to 51, but produced no measurable impact on firm hiring. Candidate identity verification alone yielded zero statistically measurable increase in hiring relative to the comparison group.RCT Behaviour & psychologyDual-Channel Performance EnhancementTechnical assistance improved final exam scores, revenue calculation accuracy, and business analyses performed; role models boosted optimism, seed fund applications, and business continuity without changing exam scores. Both channels independently raised household income by 15% (US$30–US$50/month).RCT Methods & evidenceDual-Channel Branch and Intercept RecruitmentRetention rates remained highly balanced across recruitment channels (56% retained inside MTO branches vs. 52% retained in public areas), confirming observable baseline balance across gender (74% female), age (mean 35 years), and monthly income (55% above median).RCT Labour & employmentDual Coordination Frictions in Application-Based MatchingWhile higher search effort per worker resolves the first friction (reducing empty vacancies), it exacerbates the second friction (increasing double-job offers and candidate loss), causing aggregate matching efficiency to flatten and diminish beyond optimal application thresholds.Expert Theory Labour & employmentDual-Friction Market Tightness InvarianceThe treatment impact on permanent vacancy creation with pre-screening services was statistically equivalent between low-tightness markets (+0.033) and high-tightness markets (+0.061) with a p-value for equal treatment effect of 0.386.RCT Labour & employmentIntegrated Health-Care and Employment Support Model for Low-Income MothersReceiving the health-only intervention significantly enhanced participants' self-perceived capacity to secure employment, while both the employment and combined interventions resulted in statistically significant increases in earned income relative to the comparison group.RCT Labour & employmentDual-Market Screening FrictionsTreatment effects on permanent contract vacancies (+0.031 in below-median vs +0.038 in above-median, p = 0.550) and permanent contract jobseeker hires (+0.056 in below-median vs +0.038 in above-median, p = 0.711) showed no statistically significant difference between slack and tight markets.RCT Economics (general)Dual-Market Side Insurance NeutralityJoint coverage eliminates net market wage volatility relative to a no-insurance baseline, while increasing median rainfall wages by 11.7% and 80th percentile rainfall wages by 19%.RCT DevelopmentDual-Sided Balanced Insurance Market StabilizationSimultaneously marketing rainfall insurance to both cultivators and laborers eliminates excess wage volatility relative to a no-insurance baseline, while increasing average daily wages by 11.7% at median rainfall and by 19.0% at the 80th percentile of rainfall.RCT Labour & employmentDual-Sided Over-Optimism in Labor Market Fundamentals75% of firm managers overestimate the cognitive ability of tertiary-educated applicants (perceiving a tertiary Raven score premium $>4\times$ the actual difference of 5.3 vs 5.0 questions); 55% of high-school jobseekers expect permanent employment within 1 year compared to 5.8% actual observed employment.Observational Study Labour & employmentDuration Dependence Bias in Treatment Intensity CalibrationAccounting for negative duration dependence reduces estimated baseline treatment intensity from 30% to 26% (and down to 21% when adjusting for reduced benefit inflow). Lower assumed baseline treatment intensity ($\tau^e = 0.20$) implies stronger displacement externalities on nonparticipants, causing social welfare to decline faster as program scale increases.Observational Study Labour & employmentDynamic Covariate Updating in Treatment SelectionBiweekly prediction recalculations dynamically shifted optimal recommended interventions over the unemployment spell, demonstrating that optimal programme timing varies substantially across individuals as unemployment duration accumulates.RCT DevelopmentGlobal E-Commerce Quality SignalingInterventions that improved small exporters' platform visibility and quality signaling to prospective international buyers successfully increased firm export sales by overcoming market search frictions.RCT Labour & employmentEarly Wage Liquidity ReliefEarly pay increased overall production by 0.27 leaf plates per hour (a 7% increase relative to the comparison group). For workers under high preexisting financial strain, production increased by 0.5 plates per hour, whereas lower-strain workers experienced no significant change. Within three days of early pay, loan repayment probability increased by 40 percentage points (a 222% increase from an 18% baseline), food spending rose 25% from INR 270 ($4.17), and general expenditures rose 65% from INR 573 ($8.84).RCT DevelopmentEconomic Autonomy and Reproductive Agency LinkContextual findings show 44% of married adults in India do not use contraception and female sterilization is the primary method; evaluation results for earnings, empowerment, and fertility are ongoing/forthcoming.RCT DevelopmentEconomic Targeting for Social Norm ShiftStructuring public wage payments through female-owned bank accounts and training led to a 0.08–0.09 standard deviation liberalization in the perceived gender norms index without direct norm messaging campaigns.RCT Behaviour & psychologyEconomic Trade-Off Benchmarking of Identity BiasControl group participants were willing to forgo grocery items worth nearly twice the median daily per capita food expenditure to avoid hiring a transgender worker; participating in 3-person group discussions reduced this willingness to sacrifice grocery items to zero on average.RCT Labour & employmentEducated Youth Underemployment TrapDespite completing secondary school (13 average education years), urban young men worked an average of only 23.4 hours per week conditional on being employed, while earning approximately $210 per 3-month period prior to intervention.Observational Study Labour & employmentEducation-Driven Apprentice Self-SelectionFormal apprentices were 47.5 percentage points less likely to have no education (p < 0.0001), 34.8 percentage points more likely to have completed primary education (p < 0.0001), 2.10 years older on average (p < 0.0001), and 23.0 percentage points more likely to aspire to formal wage employment (p < 0.0001) compared to traditional apprentices in control firms.RCT DevelopmentRemittance Labeling Education Spending ReductionRemittance labeling caused a statistically significant reduction in log household educational expenditures of -0.432 log points across the full sample (p < 0.05) and -0.448 log points in the above-median baseline remittance subsample (p < 0.10).RCT EducationTreatment Effect DecayInitial short-term learning gains decayed to approximately 0.10 standard deviations for targeted low-scoring students in remedial education and 0.09 standard deviations in math for computer-assisted learning one year post-program.RCT Labour & employmentEducational Heterogeneity in Information FrictionsHigh-school educated jobseekers doubled their permanent employment rate from 5.8% to 11.6% (ITT = +5.76 percentage points, p < 0.05) and increased formal employment by 45% (+4.82 percentage points, p < 0.10), driven by an 8.7% reduction in reservation wages (p < 0.10); post-secondary jobseekers showed no statistically significant change in permanent employment (-2.6 percentage points, p > 0.10) or reservation wages (-3.5%, p > 0.10).RCT Finance & microfinanceEducational Heterogeneity in Financial Innovation TakeupAmong literate farmers, assignment to the insurance treatment group increased cash crop investment likelihood by 15 percentage points, whereas among illiterate farmers, the treatment effect was statistically indistinguishable from zero.RCT Labour & employmentEffective Wage Differential Bundle MechanismThe logit intercept divided by the slope directly identifies the marginal value of time, proving that effective wage variation cleanly isolates willingness to supply incremental work hours without income effects.RCT EducationEffort-Focused Teacher FeedbackOver 95% of participating teachers agreed with the growth-oriented teaching philosophy and over 90% implemented the effort-praise feedback framework moderately or intensely in their classrooms.RCT EducationElite School Non-Participation FilterFewer than 50% of private secondary schools accepted the voucher; non-participating elite schools charged substantially higher tuition and maintained significantly higher teacher-pupil ratios, restricting voucher usage to low-to-middle income private schools.Observational Study EducationEmpirical Bayes Shrinkage Estimation for Volatility AdjustmentUsing raw value-added scores without shrinkage generated actual achievement differences following random assignment that were only 43% as large as predicted (coefficient = 0.430, SE = 0.057). Single-year math value-added required multiplication by shrinkage factors of 0.396 in elementary and 0.512 in middle school to predict future performance.RCT Labour & employmentEmployability-Driven Effect HeterogeneityFor job seekers with low employability (predicted median duration exceeding 6 months), assignment to an early integration agreement (month 1 or 3) increased the 1-year re-employment probability from 45% (month 6 reference group D) to 53% (group A) and 54% (group C) (p < 0.01), representing an 8 percentage point or 18% relative increase; for high-employability job seekers, early integration agreements had no statistically significant effect (82% vs 82–83%).RCT Labour & employmentEmployed vs. Unemployed MVT DivergenceThe overall sample (including employed workers) yields a higher implied flow value of time ($\tilde{z} = 0.64, s.e. = 0.03$) compared to the unemployed sample ($\tilde{z} = 0.58, s.e. = 0.04$), reflecting inter-job hours substitution costs among employed applicants.RCT Behaviour & psychologyEmployee-Defined Commitment ContractsWorkers voluntarily selected positive production targets 28% of the time, and choosing commitment contracts increased production by 120 fields (a 2% increase over the baseline of 5,311 fields), while evening target choices boosted earnings by 3%. Workers missed self-selected targets only 2.6% of the time compared to 8.6%–14.1% for firm-imposed targets.RCT Labour & employmentEmployer Asymmetric Hire Risk AversionRecruiters overwhelmingly reported that risk management drives screening; negative past experiences with single foreign-experienced hires caused recruiters to categorically penalize subsequent applicants of similar ethnicities, prioritizing safety over peak potential productivity.Observational Study Labour & employmentEmployer Intermediary Demand AlignmentMature providers with deep sector employer connections generated far higher outcomes; Per Scholas achieved a 41 percentage point gain in targeted IT employment (61% vs. 20%, p < 0.01) and a 19.6% long-term earnings increase in Year 6 (p < 0.01), whereas newer providers lacking established employer relationships generated smaller or non-statistically significant initial earnings gains.RCT Labour & employmentExternal Employer Prescreening ServicesProviding prescreening hiring services directly to firms reduced employer evaluation costs and accelerated vacancy fill rates across participating businesses.RCT Labour & employmentEmployer-Provided Transport Infrastructure and Female Spatial MobilityProviding recruited placement channels with safe transport options enabled a 4.6 percentage point increase in BPO employment (p < 0.01) and a 2.4 percentage point increase in total female employment outside the village (p < 0.05), overcoming baseline travel restrictions.RCT Labour & employmentEmployment Path Dependency and ScarringHaving temporary or informal work after 1 year showed zero statistically significant correlation with 4-year earnings compared to remaining unemployed. Short-run permanent work status accounted for 23% and short-run earnings accounted for 56% of the total 4-year earnings treatment effect.RCT Labour & employmentEndogenous Incentive-Driven Referral ParticipationHigh-ability participants facing high-stakes performance pay were 16.2 percentage points more likely to return with a referral (p < 0.05), while low-ability participants showed no statistically significant increase in participation (3.0 percentage points, p > 0.10).RCT Labour & employmentEndogenous Stratification Equity GainsFor the lowest-predicted-earnings stratum, the job application workshop increased 4-year earnings by 50% over the control mean (p = 0.0696 for equality with the high-predicted-earnings group). This intervention reduced the earnings gap between high- and low-predicted earners from 142% down to 54%.RCT Labour & employmentEndogenous Stratification and Equity GainsThe application workshop generated a **467.1 ETB monthly wage increase** for the low-predicted-earnings group (50% of control mean, p < 0.01) compared to a -99.0 ETB non-significant effect for the high-predicted-earnings group (p = 0.0696 for equality), **reducing the high-to-low earnings gap from 142% to 54%**.RCT Labour & employmentEndogenous Vacancy Supply ResponseLog vacancy stocks in experiment counties increased significantly, peaking at an 18.2% increase (p < 0.01) in May/June 2006 (3-4 months post-assignment), resulting in a projected 2.4% net increase in overall economy-wide vacancy supply under full program rollout.Observational Study Labour & employmentEnglish Female Callback PremiumResumes with English female names received a 4.9 percentage point higher callback rate than English male names (p < 0.01). However, no female callback premium existed for Indian, Pakistani, Chinese, or Greek female applicants compared to their male ethnic counterparts.RCT DevelopmentSoft Skill Enhanced Social Entitlement and Benefit UtilizationSoft skills training increased worker utilization of government pensions by 2.48 percentage points (p < 0.10; relative to control mean of 3.9%) and government-subsidized healthcare by 2.26 percentage points (p < 0.05; relative to control mean of 0.6%, representing a nearly four-fold increase).RCT DevelopmentCapital Deployment and Factor AllocationHigh-potential microentrepreneurs (top third ranked by peers) invested significantly more in business inventory and durable assets while decreasing household expenditure, working an additional 9.9 hours per week and 4.6 days per month compared to lower-ranked recipients.RCT HealthEntrepreneurial Community Health Promoter ModelUnder-five child mortality decreased by 27% (48.5 vs. 68.4 deaths per 1,000 births), infant mortality decreased by 33% (32.4 vs. 49.7 per 1,000), and neonatal mortality fell by 28% (24.1 vs. 33.4 per 1,000) at an average cost of $65 per year of life saved.RCT Firms & operationsEntrepreneurial Experimentation HypothesisInitial adoption of business practices increased management scores by 5.65 percentage points at 6 months (p < 0.01) and capital grants increased short-run investments by 179 cedis (p < 0.10). However, treatments led to non-positive or negative income shifts (capital treatment reduced stated income by 45.43 cedis, p < 0.05), causing microentrepreneurs to abandon new business practices and revert back to baseline scale within 1 to 2 years.RCT DevelopmentEntrepreneurial Risk-Taking and Business DiversificationGrace period recipients were 11.3 percentage points more likely to sell goods on credit (control mean 43.2%), 10.7 percentage points more likely to accept pre-orders (control mean 39.5%), offered 6.05 additional product/service categories, and exhibited Rs 713.9 higher profit variation between high and low seasons.RCT Labour & employmentBusiness Entry Simplification (Salaried-to-Entrepreneur Shift)Startup simplification increased the total number of registered businesses by encouraging former formal salaried workers to launch new enterprises, but had zero effect on the registration likelihood of pre-existing informal firms.Observational Study Labour & employmentEquilibrium Displacement ExternalitiesAt baseline French market tightness ($\theta = 0.42$), displacement externalities reduce net aggregate job creation to 68%–73% of the measured firm-level treatment impact ($ED(\sigma)/\sigma AB \approx 0.68\text{--}0.73$), demonstrating that equilibrium spillover losses offset roughly 27%–32% of firm-level hiring gains.Expert Theory Labour & employmentEquilibrium Search Modeling via Indirect InferenceA full rollout ($\tau = 1.0$) decreases overall social welfare by 0.13% and increases aggregate government spending due to high program costs (2,122 DKK per worker) and market congestion. While microeconometric methods wrongly estimate a 4,094 DKK net gain per participant, structural modeling proves welfare is maximized at 20% participation and government expenditure is minimized at 30% participation.Expert Theory Economics (general)Ethnic Buyer Bargaining Strategy DisparitiesBuyer ethnicity significantly affected settlement outcomes: Andhra buyers paid higher final prices, Marwari buyers paid the lowest prices, and Tamil buyers received lower advance payment demands than Marwari or Andhra buyers.RCT Labour & employmentEthnic Name Hiring DiscriminationChanging an applicant name from an English-sounding name to an Indian, Pakistani, or Chinese name reduced interview callbacks by 4.4 percentage points (from 15.7% down to 11.3%), meaning English-named applicants were 39% more likely to receive a callback. Resumes with Greek names experienced a statistically significant 4.0 percentage point reduction in callback rates compared to English names.Observational Study Economics (general)Evaluation-Induced Gender BiasWhen subjective evaluations directly determined financial raises, male teachers received 10% higher performance ratings controlling for teacher actions and student outcomes; when evaluations carried no financial stake, no evaluation difference by gender existed.RCT Methods & evidenceEvaluation Time Horizon BiasThe estimated intervention effect was 0.085 SD (p < 0.05) after 1 year (before household reoptimization), but fell to a statistically insignificant 0.053 SD (p = 0.611) after 2 years once households adjusted private spending.RCT Economics (general)Ex-Ante Input Complementarity vs. Ex-Post Harvest Labor DecouplingInsurance significantly increases the rainfall elasticity of harvest labor demand ($\beta = 0.654, t = 2.39$), but has no statistically significant effect on planting-stage labor demand ($\beta = 0.459, t = 1.41$ or $\beta = 0.191, t = 0.48$ in placebo specifications).RCT DevelopmentEx-Ante Production Effect Payout DecouplingThe investment effect on cash crop planting emerged sharply during the initial sowing window months before coverage ended, and regression interaction terms between insurance assignment and actual ex-post payout levels were statistically insignificant.RCT Labour & employmentEx-Ante Regime Notification EffectExit rates from unemployment began diverging significantly between treatment and control groups almost immediately upon receipt of the notification letter in week 2, well before mandatory 18-week full-time programs commenced.RCT Economics (general)Ex-Ante Risk Distortion in Agricultural Input SelectionOffering index insurance induced cultivators to increase harvest labor demand by 0.654 days per mm/day of excess rainfall (t = 2.39), representing a 22% relative increase in labor demand sensitivity under favorable rainfall conditions.RCT DevelopmentEx-Ante Hedging vs. Ex-Post Payout AnticipationThe probability of planting cash crops increased sharply during the insurance distribution period well before policy end dates, and the magnitude of production response was statistically uncorrelated with actual ex-post realized payouts.RCT Economics (general)College Entrance Exam Participation Graduation ProxyBecause 90% of high school graduates sit for the ICFES exam, registration served as a high-precision proxy for high school completion, revealing that vocational voucher winners were 5 to 6 percentage points (a 25% relative increase) more likely to complete secondary school than losers.RCT Firms & operationsExecutive Attention BottleneckA reduction in director managing time caused 3.6% of all management practices to be dropped across study plants (representing nearly 30% of the total 12.4% dropped practices), as directors reallocated hours to marketing, finance, or external real estate ventures.RCT EducationExisting Computer Lab Infrastructure LeverageLeveraged existing labs to deliver instruction at a low marginal cost of $14.60 per student, though 3 of 46 treatment groups suffered non-implementation due to localized internet connectivity failures.RCT Methods & evidenceExogenous Failure AssignmentAmong the subset forced into the difficult task who failed in Round 1 (N = 558 in Sample A, N = 522 in Sample B), treated students re-attempted the difficult task in Round 2 at rates 17.6 percentage points higher in Sample A (p = 0.002) and 13.9 percentage points higher in Sample B (p = 0.064) than control group baseline rates of 36% and 51%.RCT Methods & evidenceExogenous Boundary Redistricting for Sorting ControlEstimated choice parameters for driving distance, home-school preference, and test scores in the reassigned subsample were quantitatively and qualitatively similar to the full sample (middle school distance parameters -0.255 vs -0.234 for white non-lunch students), confirming that residential sorting does not drive preference estimates.Observational Study DevelopmentExogenous Remittance Expansion and Household Human Capital AccumulationPositive exogenous remittance shocks significantly increase household probability of escaping poverty status, elevate child school enrollment rates, and increase capital investment in household entrepreneurial enterprises.Observational Study Labour & employmentExperience-Based Recruitment Bottleneck34.38% of firm managers cited "insufficient work experience" as their primary reason for not hiring candidates met at job fairs (the single most cited reason), while 59% of firm professional vacancies required 2 or more years of formal experience compared to jobseekers where 50% believed no experience was necessary for high-skilled roles.Observational Study Firms & operationsExperience-Based Training TargetingRole model interventions yielded substantially larger income and growth impacts for younger businesses with less experienced owners, whereas individualized technical assistance delivered greater benefits for highly educated owners with mature businesses.RCT Behaviour & psychologyExperienced Participant Valuation SpilloverNew participants expressed a statistically significant higher willingness to pay for insurance policies (approx. Rs. 6–8 higher per policy) relative to returning multi-year study participants.RCT Methods & evidenceExperimental Self-Selection Verification and External ValidityProject firms showed no statistically significant differences from nonproject firms in pre-intervention assets ($12.8M vs $13.9M, p = 0.841), employees (204 vs 221, p = 0.552), total borrowings ($4.9M vs $5.5M, p = 0.756), or baseline BVR management scores (2.52 vs 2.55, p = 0.859).Observational Study Economics (general)Expert Forecast OveroptimismLocal field staff exhibited substantial overoptimism, predicting median 6-week employment rates of 20% for cash, 10% for information, and 9% for nudge (compared to actual control/treatment rates under 5%). Senior international staff had more accurate median forecasts (7% for cash, 5% for info, 4% for nudge). Both groups correctly anticipated that cash would be the most effective intervention.RCT DevelopmentExport Market AccessExporting firms achieved a 26 percent increase in monthly profits and a 43 percent increase in unit prices relative to comparison firms, despite a 5 percent increase in hours worked.RCT Labour & employmentExport Sector Female Labor EmpowermentExpansion of garment export manufacturing created formal female employment opportunities, which enhanced female empowerment and resulted in statistically significant reductions in domestic violence across surrounding communities.Observational Study DevelopmentExtension Intermediary Information DistortionSales failed entirely in 11 out of 34 treatment cooperatives (32.4%) due in part to indirect, distorted communication passed through extension agents and model farmers, leaving farmers confused about policy terms.Observational Study Crime & justiceExtensive Margin Dominance in Youth Crime PreventionSYEP participation decreases the probability of any arrest by 0.128 percentage points (a 17% reduction, p < 0.05) and decreases total arrest counts by 0.00122 arrests per youth (a 15% reduction, p < 0.10) on a control mean of 0.0087. The virtually identical relative percentage reductions (17% vs 15%) demonstrate that criminal deterrence operates almost entirely by preventing first-time arrest contact rather than reducing repeat arrests among already-arrested individuals.RCT DevelopmentExtensive Margin Investment JumpProviding rainfall index insurance increased the probability of planting cash crops by 6 percentage points (p = 0.041) on the extensive margin, but caused no measurable change in input investments among producers already in the top distribution tier of cash crop farming.RCT Labour & employmentExtensive Margin Labor Force Participation InertiaWinning 1M SEK reduces labor force participation probability by 2.015 percentage points (2.6% relative drop, p < 0.001); for workers aged 50+, a 1M SEK prize increases early retirement pension uptake by only 0.246 percentage points, which is statistically insignificant (p = 0.603), confirming strong participation inertia around standard institutional retirement ages (modal age 65).RCT DevelopmentExtensive Margin Remittance ResponsivenessAcross the full sample, remittance labeling caused a statistically significant increase on the extensive margin of sending at least one weekly remittance (+0.007 probability, p < 0.10), while the effect on total weekly winsorized remittance amount (-29.78 PhP, p > 0.10) and total remittance index (+0.013, p > 0.10) was statistically non-significant.RCT DevelopmentExtensive Margin Scale Threshold in Crop AdoptionInsurance provision drove investment increases strictly on the extensive margin (shifting non-cash-crop farmers to positive production, p = 0.041) with a discrete jump once positive planting occurred, but had zero impact on the intensive margin for top-tier producers.RCT Labour & employmentParticipation vs. Effort Elasticity (Extensive vs. Intensive Margin)Arc elasticity of labor participation (extensive margin) with respect to the piece rate is 0.58, whereas the elasticity of daily output quantity (intensive margin) with respect to the piece rate is only 0.06 (controlling for reservation rates).RCT Labour & employmentExtraversion as a Behavioral Mediator of Soft Skill Productivity GainsSoft skills training increased worker extraversion by 0.164 standard deviations (p < 0.05), with mediation analysis establishing that gains in extraversion accounted for approximately 30 percent of the total 10.8 percentage point increase in workplace productivity.RCT DevelopmentFace-to-Face vs. Virtual Peer Interaction Scalability Trade-OffFace-to-face interaction yields a statistically significant positive effect on proposal submission ($\beta = 0.126, p < 0.01$ full sample; $\beta = 0.151, p < 0.05$ M0 completers) and extensive quality ($\beta = 0.411, p < 0.05$), but fails to generate a statistically significant effect on intensive business quality ($\beta = 0.180, p > 0.10$).RCT Methods & evidenceFacebook Social Proof for Field Survey ParticipationSocial proof validation helped overcome initial refusal challenges, enabling successful enrollment of 8,248 participants and sustained engagement across 51,395 weekly survey responses over 30 weeks.RCT DevelopmentFactor Market Allocative DisequilibriumThe marginal product of purchased cash inputs is 4.5 (statistically different from market price 1.0 at p < 0.05), indicating severe input underuse.

In contrast, cash had no significant effect on Jordanians (-0.007 at 2 months, -0.025 at 4 months), as Jordanians had 25% higher baseline daily expenditure, searched 30% more intensely, and filed twice as many job applications in the control group.RCT DevelopmentIntra-Budget Consumption Substitution for Female SchoolingTotal household monthly per capita expenditure remained unchanged (-21.2 INR, p > 0.10), but households with school-aged girls significantly increased the budget share devoted to schooling expenses, offset by small, statistically insignificant reductions across multiple other consumption categories.RCT Finance & microfinanceHousehold Income Shock Vulnerability62.0% of households reported an income shock in the previous month, 16.0% missed work days due to shocks, 19.0% reported chronic household illness, and households reported recovering only 37.0% of inventory value during emergency 24-hour liquidations.Observational Study EducationHousehold Input SubstitutionIn Year 2 of the Indian experiment, household education spending dropped by 0.76 dollars for every 1 dollar of anticipated school funding (elasticity of -0.21, p < 0.01), demonstrating substantial crowding out of 50% to 100%.RCT Methods & evidenceRecipient Household Welcome Call Rapport StrategyThe preliminary welcome call strategy enabled completion of 2,075 detailed endline household surveys despite high phone survey attrition challenges (with only ~10% explicit refusal rate).RCT Labour & employmentHousewife-to-Entrepreneur Occupational ShiftParticipants who attended business training with a friend experienced a 4 percentage point (40 percent relative) reduction in reporting their primary occupation as housewife, accompanied by significantly increased labor hours worked and higher total sales compared to control subjects.RCT Policy & public sectorHousing Assistance Leaky Bucket Efficiency LossVoucher usage reduces recipient annual earnings by $1,316, representing approximately 19 percent of the $6,860 recipient subsidy value, alongside a direct $1,540 gap between government outlay ($8,400) and equivalent variation ($6,860).RCT Policy & public sectorMeans-Tested Housing Voucher Work DisincentiveVoucher utilization reduced quarterly employment rates by 3.6 percentage points (6 percent of control complier mean), reduced quarterly earnings by $329 (10 percent of control complier mean), and increased public assistance participation by 6.7 percentage points (12 percent of control complier mean).RCT DevelopmentHuman Capital Moderation of Risk HedgingAmong literate household heads, insurance provision increased the likelihood of investing in risky cash crops by 15 percentage points (p < 0.05), whereas among illiterate household heads, the treatment effect was indistinguishable from zero.RCT HealthHuman Rights-Based Sexual Health EducationSix months post-intervention, treated students showed a 0.25 SD increase in sexual violence knowledge (p < 0.01) and a 0.26 SD increase in attitudes supporting the reporting of sexual abuse to authorities or medical professionals (p < 0.01).RCT Methods & evidenceHybrid Administrative Record Linkage OptimizationThe hybrid four-tiered matching protocol achieved a 1.97% false positive error rate and a 2.46% false negative error rate overall (compared to exact matching alone which yielded a 0.8% false positive rate but an 8.0% false negative error rate), minimizing overall attenuation bias in binary outcome estimation.Observational Study Finance & microfinanceHybrid Targeting ModelMicroentrepreneurs ranked in the top third based on observable traits alone achieved monthly returns of 13.6 percent, whereas those selected using both observable traits and community peer information achieved monthly returns of 38 percent.RCT HealthScalable Internet-Based Sexual Health CurriculumGenerated a 0.38 standard deviation improvement in overall sexual knowledge (p < 0.01) and a 0.17 standard deviation improvement in sexual attitudes (p < 0.01) six months post-course.RCT EducationIdeological Externality Risk in Choice MarketsIdentifies ideological polarization and radical instruction as distinct negative externality channels in voucher markets that operate independently of peer sorting and school capacity constraints.Expert Theory Finance & microfinanceHigh-Return Illiquid Business OpportunitiesMicro-entrepreneurs undertaking illiquid investments experienced 80% higher long-run business capital, higher profit variance across months (an average Rs 600 wider gap between high and low profit months), a 9 percentage point increase in extending customer trade credit, a 10 percentage point increase in customer pre-orders, and reduced long-run business closure rates (31.4% treatment vs 38.6% control).RCT DevelopmentImmediate Credit & Consumption ResponseWithin three days of early payment, workers were 40 percentage points more likely to pay off loans or credits (a 222 percent increase from an 18 percent baseline). Food expenditures increased 25 percent from a baseline of INR 270 ($4.17 USD), and general expenditures increased 65 percent from a baseline of INR 573 ($8.84 USD).RCT Finance & microfinanceOvernight Debt Deleveraging BehaviorOn the exact day cash was received, loan payments increased by Rs. 169 (746% increase, p<0.001); over 3 days, treated workers increased debt repayments by Rs. 271 (287% increase, p<0.001) and were 40 percentage points (222%) more likely to pay off outstanding credit.RCT Labour & employmentImmune Subpopulation in Unobserved HeterogeneityModel estimations consistently identified a distinct subpopulation of 1% to 2% 'immune' individuals exhibiting a zero exit rate from unemployment, whose separation was required to accurately identify policy impacts among the remaining population.RCT Finance & microfinanceTime Preferences and Flexible Debt UtilizationImpatient clients assigned to a grace period generated Rs 1,193.6 lower monthly profits relative to patient clients (p < 0.10), demonstrating that high baseline discount rates attenuate grace period benefits.RCT DevelopmentImperfect Labor Substitutability in MicroenterprisesDespite an 81.0% increase in business capital stock among grace period households, total enterprise workforce adjusted marginally from 2.53 workers in control to 2.89 workers in treatment, a difference that was statistically insignificant.RCT Policy & public sectorIn-Kind Housing Benefit Budget Constraint KinkThe average maximum subsidy of $8,265/year carries an estimated equivalent variation of $6,860/year (benefit-to-subsidy ratio of 0.83), reflecting a 17 percent subjective value discount due to in-kind consumption constraints.Expert Theory Labour & employmentIn-Person Labor Inspection and EnforcementIn-person labor inspections increased worker formalization in Brazil and Mexico, but increased worker dismissal rates in Mexico and reduced overall job creation due to higher informal employment costs.RCT Economics (general)Inattention Mixture Model CorrectionInattention affects choice variance without biasing central tendencies; the inattention-corrected flow value parameter ($\tilde{z} = 0.58, s.e. = 0.04$) matches the standard logit baseline ($\tilde{z} = 0.58, s.e. = 0.04$) identically across all hour choices.RCT Economics (general)Community Incentive and Distance Instrumental Variable MethodThe first-stage regression predicting the proportion of village members learning HIV results yields a strong F-statistic of 23.98 without controls, with an average of 72.3% of village members learning test results (SD = 0.186).RCT EducationIncentive-Driven Pedagogical DistortionObjective incentives caused a 5-fold increase in class time spent on test preparation (rising from 0.14 to 0.76 minutes per 20-minute segment, p < 0.01), reduced CLASS pedagogy scores by 0.07 points (p < 0.10), decreased student love of learning (p < 0.10), and increased student desire to switch schools by 0.086 standard deviations (p < 0.10).RCT Behaviour & psychologyIncentive Signaling and Intrinsic Motivation ParadoxOffering €250 per month increased meeting attendance by 5.3 meetings (ITT, p < 0.01) from a control mean of 7.3, costing an additional €1,530 to €1,868 per participant over two years. However, treatment generated precisely zero impact on overall human capital investment (index effect +0.019, p > 0.10) and caused a temporary 3 percentage point decrease in full-time employment during the first six months (p < 0.05).RCT HealthCost-Effectiveness of Incentivized Health DeliveryThe average cost per year of life saved by Community Health Promoters was US$65 in 2013, compared to baseline cost-effectiveness estimates for volunteer-based health programs ranging from US$82 to US$3,396 per year of life saved.RCT Finance & microfinanceFinancial Incentive Encouragement for Low-Baseline Take-up RatesUnincentivized workshop participation yielded only 36 attendees out of 487 invited and 4 savings account sign-ups out of 438; adding financial incentives and revisits boosted final workshop participation to 38.9%–41.4% (p < 0.01) and micro-insurance take-up to 25.1%–28.0% (p < 0.01).RCT Methods & evidenceIncentivized Lab Game Behavioral ForecastingEvery 100 € allocated to direct payment in the game increased real-world EduPay take-up by 2.07 percentage points (p < 0.01; an 8.7 percentage point increase per 1 SD, representing a 32% increase relative to the 27.1% mean take-up rate).RCT Methods & evidenceIncentivized High-Frequency Micro-SurveysThe micro-survey protocol achieved a retention rate of 54% over 30 weeks while capturing 137,927 weekly survey observations verified through photo receipt submissions.RCT Methods & evidenceIncentivized Real-Effort Grit ElicitationExperimental choice of the difficult task in all 5 rounds strongly predicted baseline math test scores (coef = 0.346, p < 0.01) and Turkish scores (coef = 0.152, p < 0.05) over and above Raven cognitive matrix scores (coef = 0.437, p < 0.01).RCT Behaviour & psychologyIncentivized Token Peer-Reward MechanismToken references were among the top 10 most frequent terms in individual-to-individual messages (terms such as "token", "giveusername", "leaderboard"). The bilateral token economy successfully induced strategic peer searching and reciprocal communication across virtual channels.RCT EducationIncome Elasticity of Education DemandThe observed 76% private expenditure offset yielded an estimated income elasticity of education spending between 1.8 and 4.6, confirming that education acts as a luxury good and families reallocate funds rationally across household budget lines.RCT Policy & public sectorIncome Source Substitution EffectWhile treated jobseekers received a mean public transfer increase of €87 per month at month 12, this was offset by a €47 per month reduction in alternate income sources (€26 decrease from employment, €10 decrease from parents, and €11 decrease from other non-work transfers). Consequently, net personal income rose by only €40 per month (ITT, p < 0.05) relative to the control mean of €602 per month.RCT Labour & employmentIncome Tapering Disincentive EffectMonthly cash benefits were reduced linearly against labor earnings up to the minimum wage (€1,050/month), creating an implicit tax rate of 24%. During the first six months, full-time employment declined significantly by 3 percentage points (ITT -0.18 months of total employment from a control mean of 2.41 months, p < 0.05; TOT -0.21 months, p < 0.01), though this negative employment effect disappeared by the second year.RCT DevelopmentIncreasing Scale Economies in Smallholder AgricultureConstant returns to scale was rejected (F-value = 6.16, p = 0.0131), confirming increasing economies of scale with input elasticities for land (0.133, p < 0.05), labor (0.827, p < 0.01), capital (0.070, p < 0.05), and intermediate inputs (0.477, p < 0.01).Observational Study Finance & microfinanceIndex Basis Risk SensitivityAssigning an insurance policy to a distant weather station (introducing substantial basis risk) reduced farmer willingness-to-pay by Rs. 29.45 (p < 0.01), effectively halving consumer valuation from the baseline average bid of Rs. 68.40 despite identical actuarial expected payouts.RCT Finance & microfinanceExogenous Indexing for Moral Hazard EliminationLinking payouts strictly to third-party automated rain gauges eliminated individual claims verification costs and completely removed moral hazard and adverse selection incentives.Expert Theory Methods & evidenceIndirect Inference Structural EstimationThe structural parameters matched the reduced-form empirical moments (treatment exit rate, control exit rate, regional comparison exit rate, and vacancy response curves), validating structural policy simulation counterfactuals.Expert Theory Economics (general)Indirect Wage-Mediated Insurance ExternalitiesA 10% increase in the proportion of wage laborers offered insurance raises village wages by 24.7% in payout states. Insured laborers receiving payouts worked 15.4 fewer days and had a 28.5 percentage point lower labor market participation rate than uninsured peers.RCT Methods & evidenceIndividual Fixed Effects Precision Enhancement in Panel RCTsIncluding individual fixed effects controlled for baseline individual variation, achieving an adjusted R-squared of 0.010 for weekly remittance probability and 0.012 for the low-baseline remittance subsample, ensuring identification precision across 137,927 panel observations.RCT Finance & microfinanceIndividual Liability in Group Lending SettingsAll 169 loan groups operated under individual liability with fortnightly meeting schedules, demonstrating that grace period investment gains occurred independently of joint liability financial obligations.RCT Policy & public sectorIndividual Microentrepreneur Program (MEI) Tax SimplificationThe program increased business formalization between 2009 and 2015 without causing formal salaried workers to shift into micro-entrepreneurship, but generated average monthly tax default rates between 49% and 51% from 2018 to 2020.Observational Study Firms & operationsIndividualized Technical AssistanceGenerated a US$30–US$50 (~15%) increase in monthly household income after 1 year, alongside statistically significant improvements in final exam scores, revenue calculation accuracy, and business analyses conducted.RCT Labour & employmentCapital Indivisibility under Financial ConstraintsTreated jobseekers received a net income increase of only €40 per month (p < 0.05), while 27.7% faced bill payment difficulties, 24.4% forwent medical care, and 19.4% skipped meals. Rather than increasing consumption of temptation goods (€0 impact), treated individuals were 5 percentage points more likely to save money (45.4% control mean, p < 0.05) and saved €36.80 more in the preceding quarter (an 18% increase, p < 0.05).RCT Finance & microfinanceInformal Credit Market ExclusionAt baseline, 82.5% of the 160 microentrepreneurs had never accessed formal credit markets. Over the entire two-year study period, all 160 tailors combined took a total of only 13 informal loans from non-bank sources, demonstrating near-zero reliance on informal debt markets.Observational Study Labour & employmentInformal Network Non-Displacement EffectFirms in the combination advertising and verification group increased online portal hiring by 8 percentage points (68 percent increase) while maintaining baseline recruitment volume through traditional informal networks, resulting in net total vacancy expansion.RCT Labour & employmentInformal Network Substitution for Formal Reference LettersParticipants acquiring work experience and a reference letter were 7.9 percentage points less likely to submit a reference letter when applying for jobs (IV coefficient = -0.079, standard error = 0.110) and reduced the total number of times a reference letter was submitted by 0.381 times.RCT Labour & employmentInformal Per-Diem Wage Labor PreferenceJob growth following liquidity support concentrated heavily in informal jobs paying slightly below formal monthly minimum wage thresholds, characterized by significantly higher hourly pay but fewer monthly hours worked compared to formal factory positions.Observational Study Finance & microfinanceInformal Savings in Physical AssetsControl borrowers on standard early-repayment contracts allocated Rs 557.2 to house repairs (representing 58.6% of the non-business spending gap between groups), whereas grace period borrowers reduced house repair purchases by Rs 208.8 to Rs 222.1 to invest directly in illiquid business stock.RCT DevelopmentInformal Risk-Sharing Interaction with Formal InsuranceInformal risk-sharing mechanisms efficiently handle localized, non-covariate shocks but fail to absorb spatially covariate monsoon droughts, making formal index insurance complementary rather than competitive with informal village networks.Observational Study Finance & microfinanceInformal Risk-Sharing via Group Meeting FrequencyRegular and grace period groups maintained identical fortnightly meeting schedules (14 days apart) and meeting lengths (18 minutes), confirming that social network degradation was not the driver of higher grace period default rates.RCT Finance & microfinanceInformation-Driven Substitution from Informal to Formal CreditFinancial education led to significant reductions in total borrowing (~PHP 1,935 to 2,033 reduction, p < 0.10) and shifted borrowing composition away from informal sources like family and friends by 12.7 to 16.0 percentage points (p < 0.05 / p < 0.01) toward formal lenders like banks and MFIs (+9.7 to +10.0 percentage points, p < 0.10).RCT EducationInformation Salience as Demand Elasticity ModulatorStandard choice forms produce wide preference heterogeneity across socioeconomic groups. Delivering direct, simplified test score information to low-income families significantly compresses estimated preference heterogeneity, causing low-SES parents to choose high-performing academic schools at rates comparable to high-SES parents.Observational Study Firms & operationsInformational Barriers to Management Practice AdoptionPrior to intervention, uncommon management practices had a 98.5% non-adoption rate, driven by lack of awareness (64.0%) and incorrect profitability beliefs (30.9%). Providing management information decreased uncommon practice non-adoption by 35.3 percentage points after 9 months.RCT Firms & operationsInformational Barriers to Management Practice AdoptionAt baseline, 45% of non-adoption of common operational practices stemmed from incorrect information regarding profitability, while 64% of non-adoption of uncommon practices was caused by a complete lack of awareness.RCT Firms & operationsInformational Ignorance Barrier to Management AdoptionPrior to consulting interventions, firm owners had zero quality measurement systems; initial survey evidence from the BEMMR study confirms the primary non-adoption driver was simple lack of awareness regarding modern manufacturing practices.RCT Labour & employmentInformational Labor Rights and Interview SignallingAt two months, the intervention increased Syrian job search rates by 4.7 percentage points (p = 0.123), job applications by 35% (0.423 applications, p = 0.072), wage employment by 4.7 percentage points (p = 0.036), and monthly earnings by 6.21 JOD (p = 0.092). Impacts decayed by four months to a 1.9 percentage point employment gain (p = 0.148).RCT EducationInframarginal Grant ProvisionOnly 12 percent of control group households reported spending less than the annual grant value (Rs 125/year) on their child's education, confirming the grant was inframarginal for 88 percent of households and easily offset.RCT Labour & employmentFinancial and Transport Infrastructure as Wage Volatility BuffersDaily agricultural wages are significantly higher in villages with banks (0.167–0.431 log point increase), paved roads (0.751–0.909 log point increase), and bus stops (0.107–0.542 log point increase), with transport infrastructure significantly reducing wage sensitivity to rainfall shocks.Observational Study DevelopmentInfrastructure Wage Shock DampeningPresence of a paved road increases baseline daily wages (coefficient = 0.909, t = 4.20) but reduces rainfall sensitivity of wages by 0.222 log points per mm/day (t = -7.58); bus stops reduce rainfall sensitivity of wages by 0.149 log points per mm/day (t = -3.76).RCT Finance & microfinanceInstitutional Cash Flow SynchronizationPre-treatment loan disbursement was heavily skewed (only 15% in week 1 vs 32% in week 4 across 56 of 61 branches); the intervention drove an 18% increase in new loan origination in weeks 1–2 (p < 0.10) and smoothed loan disbursements toward the target distribution (35% week 1, 25% week 2), eliminating cash flow mismatch and associated transportation/funding costs.RCT Policy & public sectorInstitutional Friction and Algorithmic Threat PerceptionCanadian authorities spent 5 years building SOMS on massive administrative data, but caseworker resistance and job security fears forced complete cancellation and deletion of the national database in 2002 before field deployment; similarly, Swiss pilot caseworkers in Geneva completely rejected SAPS (download rate <1%).Observational Study EducationInstitutional Promotion Rigidity CascadeStrict promotion criteria (failing 4 or more of 8 subjects requiring complete semester repetition) yielded a 15.6% grade repetition rate, a 15.5% annual dropout rate, and an overall on-time graduation rate of only 60.0%.Observational Study EducationInstitutional Resource Decline Impact on Degree CompletionInstitutional spending increases are demonstrably more effective per dollar than tuition price cuts in raising completion rates, proving institutional resources directly drive student graduation outcomes.Observational Study Economics (general)Institutional Substitution via Ethnic StereotypingIn environments where formal contract enforcement is missing, traders systematically utilize ethnic group affiliation (e.g., Marwari, Tamil, Andhra) to structure pricing and risk terms.RCT Behaviour & psychologyInstitutional Trust Building via Financial TransfersParticipants receiving conditional cash transfers were 7.8 percentage points more likely to express trust in the Job Youth Center after 24 months (control mean: 69.9%, p < 0.01) and 6.6 percentage points more likely after 12 months (control mean: 81.2%, p < 0.01). No significant changes were detected in underlying psychological traits such as locus of control, patience, or overall life satisfaction.RCT EducationInstrumental Variables Estimation for Experimental Non-ComplianceRandomly assigned teacher effectiveness translated into actual teacher effectiveness at a rate of 0.293 (first stage) due to non-compliance. The IV coefficient of actual teacher effectiveness on student test achievement was 0.955 (p < 0.01, SE = 0.123), proving that a 1-unit predicted difference caused a statistically equivalent ~1-unit actual achievement gain.RCT Economics (general)Insurable Interest Exclusion and GE Welfare SpilloverMarketing insurance solely to cultivators (25.6% coverage) reduces drought wages by 0.63 log points at the 30th percentile of rainfall and 0.23 log points at median rainfall. Jointly offering insurance to both cultivators (25.6%) and laborers (31.8%) eliminates wage volatility, raising median rainfall wages by 11.7% and 80th percentile wages by 19%.RCT DevelopmentInsurable Interest Regulatory ExclusionRestricting rainfall index insurance to 25.6% of landowning cultivators while excluding landless laborers reduces landless daily wages by 0.63 log points at the 30th percentile of rainfall and by 0.23 log points at median rainfall relative to a no-insurance baseline.RCT Finance & microfinanceAdministrative Payout Settlement DelaysDespite contracts stipulating settlement within 30 days of data release, actual payouts for the 2009 monsoon were delayed until December 2010 and January 2011 (over 12–13 months post-monsoon).Observational Study EducationIntake Process Enrollment FrictionPhase 1 opt-in outreach yielded a low take-up rate of 22% (94/430 students), whereas Phase 2 pre-consent enrollment achieved an 87.3% take-up rate.RCT Finance & microfinanceIntangible Management Capital Borrowing BarrierLarge manufacturing firms easily executed physical equipment investments of $1,000,000 or more without credit constraints, yet could not secure debt financing for managerial consulting because organizational practices lack seizeable collateral.Observational Study Finance & microfinanceIntangible Management Capital Financing AsymmetryWhile large manufacturing firms routinely secure physical equipment financing exceeding $1,000,000, zero firms obtain commercial loans to hire management consultants due to lack of collateralizable physical assets and bank skepticism.Observational Study Labour & employmentIntensive Margin Daily Labor Supply AdjustmentUrban educated men worked only 23.4 hours per week conditional on employment; acquiring 5 days of work experience increased labor supply on the intensive margin by 1 additional day worked per week on average (p < 0.10).RCT Labour & employmentIntensive Margin Dominance in Labor Supply AdjustmentA 1 million SEK prize reduces weekly working hours by 1.282 hours (3.9% reduction, p < 0.001) while monthly full-time equivalent wages fall by only 147.3 SEK (0.6% reduction, p = 0.080); reduced working hours account for 81% of the overall drop in wage earnings, whereas wage rate changes account for only 18%.RCT EducationIntent-to-Treat (ITT) Reduced-Form Effect EstimationThe intent-to-treat reduced-form estimate yielded a coefficient of ~0.280 to 0.326, which reflected the true treatment impact (~0.955) diluted by an overall compliance rate of approximately 29.3%.RCT Methods & evidenceIntention-to-Treat (ITT) InstrumentationIn Year 2 in Mumbai, 33% of schools assigned to receive a balsakhi tutor did not receive one due to administrative difficulties; 2SLS instrumentation successfully eliminated non-compliance bias to yield unbiased direct treatment estimates.RCT Firms & operationsInter-Firm Knowledge Spillover FailureSpillovers from outside firms accounted for only 2.2% of practice upgrades in control firms and 0.7% in treatment experimental plants between 2011 and 2017, demonstrating minimal organic cross-firm management adoption compared to intra-firm diffusion.RCT EducationInter-Program Additive IndependenceThe interaction coefficient between computer-assisted math learning and remedial instruction was -0.144 for math and -0.020 for total test scores, showing no statistically significant interaction or synergy.RCT Labour & employmentInter-Firm Job Mobility for Wage GrowthOnly 13% of workers remained in the same job after 3 years; treated workers leveraged early job security and certified signals to switch firms successfully, sustaining a 20% wage premium over control workers (p < 0.05) without working longer current job tenures.RCT Society & networksIntergenerational Gender Norm SocializationChildren over 12 whose mothers were assigned any job became 0.1 standard deviations less traditional in their gender views, whereas attitudes of younger children showed no measurable change.RCT DevelopmentInterim Liquidity Relief and Worker ProductivityReceiving an interim cash infusion increased worker output by 0.109 SDs (6.9%, p=0.020) and reduced attentional lapses by 0.08 SDs (p=0.092), with productivity gains concentrated among poorer workers (+0.204 SDs or 13.0%, p=0.003).RCT Finance & microfinanceCooperative Interlinked Credit Guarantee FailureZero interlinked loan contracts were executed due to cooperative unions refusing to guarantee non-weather default risk. Consequently, 100% of realized insurance sales were standalone policies. However, in interlinked villages, farmers who bought insurance demanded higher coverage (mean sum insured = 2,018 Birr vs. 1,295 Birr in standalone villages, p < 0.10) expecting it would unlock future credit.RCT Labour & employmentIntermediary Familiarity PremiumNet permanent hiring gains were entirely concentrated among firms with prior agency contact (+0.124 permanent hires of registered jobseekers, p = 0.021; +0.116 quality hires staying off unemployment for >=12 months, p = 0.045), whereas firms without baseline contact experienced no significant hiring impact (-0.005 hires, p = 0.435).RCT Labour & employmentIntermediate Target ConditioningCash transfers increased total months in the program by 7.9 months (ITT, p < 0.01) from a control mean of 11.4 months, and total counselor meetings by 5.3 (ITT, p < 0.01) from a control mean of 7.3. Information exposure increased by 48% (p < 0.01), yet the estimated treatment effect on the standardized human capital investment index and final employment outcomes was precisely zero.RCT Labour & employmentInternational Employer Experience PremiumThe wage returns from acquiring short-term work experience were significantly magnified for candidates with prior international employer experience, yielding an interaction coefficient of 1.731 on inverse hyperbolic sine daily wages (p < 0.05).RCT Labour & employmentInternational Experience Network MultiplierThe interaction between experimentally assigned work experience and baseline international employer experience on inverse hyperbolic sine daily wages is positive and statistically significant (interaction coefficient = 1.731, p < 0.05; Bonferroni-adjusted p = 0.041).RCT Labour & employmentIntersectoral Occupational ReallocationShort-term work experience increases subsequent employment in administrative, managerial, and clerical roles while reducing engagement in agricultural and related primary occupations across the 8-month post-intervention follow-up.RCT Behaviour & psychologyIntertemporal Goal CommitmentTreated students were 14.3 percentage points more likely in Sample A (p < 0.01) and 19.1 percentage points more likely in Sample B (p < 0.01) to commit one week in advance to the difficult task compared to control group baseline rates of 45% and 41%.RCT EducationIntervention Stigmatization and Negative SelectionTreatment group students who attended zero sessions experienced a 9.0 percentage point reduction in 11th-grade enrollment (p < 0.01) and a 6.5 percentage point reduction in overall school engagement due to social stigma associated with psychological support.RCT Society & networksIntimate Partner Backlash RiskImpact metrics evaluating domestic backlash and intimate partner violence rates following technical job training and employment are ongoing and forthcoming.RCT DevelopmentAspiration-Driven Goal Setting and Intra-Household Business DialogueAttending the training increased the proportion of upper-caste Hindu women who discussed business plans with family members by 17 percentage points (p < 0.05; baseline mean = 0.69).

Conversely, inter-firm spillovers were negligible: only 16% of 96 independent local firms had heard of the experiment and only 2% knew specific details, localized exclusively to Tarapur and Umbergaon.RCT Behaviour & psychologyIntragroup Peer Discussion for Outgroup Discrimination Reduction3-person group discussions increased selection of transgender delivery workers by 17 percentage points (a 42% increase over control), while 2-person discussions increased selection by 13 percentage points. 25% of the short-term impact persisted after 2–9 weeks (4 percentage points or an 11% increase over control), whereas public non-discussion produced no significant change.RCT DevelopmentIntra-Household Employment GatekeepingOnly 36 percent of women reported having the final say over taking a paid job, and 69 percent of participants had never worked for pay prior to the intervention.Observational Study Behaviour & psychologyIntra-Household Information AsymmetryVarying information asymmetry produced no statistically significant differences in total remittances across information settings (e.g., p = 0.127 for equality of labeling impacts across information conditions).RCT Society & networksIntra-Household Labor GatekeepingNearly 25% of women and 33% of men agreed that "women cannot go out to work," and a majority of married women reported that their husbands had the primary say in employment decisions.RCT DevelopmentIntra-Household Preference AsymmetryBaseline survey data demonstrates that migrants favor long-term investment (education, housing) while beneficiaries favor immediate consumption; unmonitored preference asymmetry reduces baseline remittances (averaging 1,311 AED per month) below potential capacity.RCT Firms & operationsSystematic Inventory Control and Dead Stock EliminationPrior to intervention, plants held an average of 4 months of raw material yarn inventory including significant unrecorded dead stock; adopting inventory tracking and norms reduced plant yarn inventory by 21.7% post-treatment without causing material shortages.RCT DevelopmentIrrigation-Fertilizer Input SubstitutionIrrigated area increases the probability of purchasing fertilizer (first stage coefficient = +0.655, p < 0.01) but significantly decreases the overall quantity/value of chemical fertilizer applied per household (second stage coefficient = -1.268, p < 0.01).Observational Study Social workIterative Service Planning and Trust BuildingService plans were collaboratively reviewed and updated every 90 days, enabling navigators to build sufficient rapport for students to disclose intimate personal crises and complete action steps across 33.8 interactions per semester.RCT Methods & evidenceInstrumental Variable Estimation under One-Sided Non-ComplianceIV estimates proved that downloading predictions had zero statistically significant impact on short-term caseworker compliance (estimates ranged from -0.05 to +0.03 across specifications, all statistically insignificant).RCT Labour & employmentJob Match Quality and Recurrence MitigationIntensive counseling significantly reduced overall unemployment duration while simultaneously extending employment tenure before unemployment recurrence.Observational Study Labour & employmentJob Search Requirements and Benefit MonitoringMandating verified job search activity as a condition for receiving unemployment insurance significantly reduced unemployment duration in Maryland. Conversely, excessive search mandates in the UK lowered long-term employment quality and post-unemployment wages, while overly rigid search quotas increased overall worker discouragement and labor force exit.RCT Labour & employmentJob Security Stress-Reduction ResponseStandardized training test scores strongly predict competitive hiring, with a 1 standard deviation score increase yielding a 9.7 percentage point higher hiring likelihood (R² = 0.357). High probabilistic job guarantees caused candidates to perform significantly better on training assessment tests due to reduced job-uncertainty stress.RCT Labour & employmentJob Stability Preference over Self-Employment64% of youth searched specifically for permanent jobs (versus 11% seeking temporary work), work stability was the second most cited desirable job characteristic (20.4% versus 6.7% for working hours), and only 5.4% cited starting a business as a reason for non-search.Observational Study Labour & employmentJobseeker Attribute Selection InvarianceTreatment effects on applications did not differ significantly by employer-graded CV quality (interaction p = 0.186). Mean predicted interview probabilities based on observed jobseeker traits were identical at 6.3% for inframarginal and 6.3% for marginal applications (p = 0.874).RCT DevelopmentJoint Buyer-Supplier Value Chain TrainingTraining farmers directly alongside exporting firms increased the adoption of improved farming practices and significantly raised the probability of securing formal contract-based sales at higher market prices.RCT Labour & employmentJoint Complementarity of Scale and Verification IntermediariesThe joint treatment increased employer-initiated candidate contact by 147% (from 2.5 to 6.2 candidates) and increased interview likelihood by 25% (13 percentage points). Jointly treated firms were 8 percentage points (68%) more likely to hire from the portal and 11 percentage points (73%) more likely to retain the portal hire after 6 months.RCT Labour & employmentThe Jordan CompactPledged 200,000 work permits for Syrian refugees in agriculture, construction, and manufacturing by relaxing administrative barriers and trade rules of origin. However, 93% of urban refugees initially remained below the national poverty line ($5/day), and control group employment rates remained low at 2.7% for Syrians and 6.8% for Jordanians.Observational Study Economics (general)Jordan Compact Policy FrameworkEased administrative procedures in manufacturing, agriculture, and construction to issue up to 200,000 work permits, establishing a global model for refugee economic integration later adopted in Ethiopia.Observational Study Firms & operationsKinship-Bound Firm Expansion and Delegated GovernanceThe number of male relatives (brothers and sons) of a firm owner directly predicts overall firm size and plant count; owners with multiple male relatives establish multiple plants even when poorly managed, whereas the best-managed firm with no male relatives operates only a single plant.Observational Study Firms & operationsKinship Delegation as Firm Expansion ConstraintThe count of owner brothers and sons directly predicted firm size and plant expansion; well-managed firms with zero brothers/sons operated only a single plant, while poorly managed firms with multiple male relatives established multiple production plants.Observational Study DevelopmentKinship Property Protection and Female SeclusionMuslim women face the highest restriction index score (1.70 out of 5), driven by external kinship boundary restrictions aimed at protecting family real estate shares, resulting in zero statistically significant gains in borrowing or business income post-training.Observational Study DevelopmentKinship Target Beneficiary InvarianceTreatment interaction by parental beneficiary status produced no statistically significant heterogeneity in overall remittance probability (+0.003 effect size for non-parents, p > 0.10; +0.001 for parents, p > 0.10).RCT Methods & evidenceKling Summary Index AggregationThe Kling labeling index demonstrated a statistically significant treatment take-up effect (mean index = 1.233, t = 44.445, p < 0.001) and a statistically significant overall remittance increase in the low-baseline subsample (+0.027 index units, p < 0.01).Observational Study Methods & evidenceKling Summary Index Aggregation in Multi-Outcome RCTsThe overall labeling treatment effect on the aggregated Kling remittance index across the full sample was +0.013 standard deviations (p > 0.10), while for the low baseline remittance subsample it reached +0.027 standard deviations (p < 0.01).RCT Labour & employmentLabeled Cash Transfers for Refugee Job SearchFour months post-treatment, the cash grant increased Syrian refugee employment by 3.8 percentage points (a 70% increase over control) and raised earnings by 65% (p = 0.040). It doubled job retention rates from 3.3% to 6.2% (p = 0.036) and increased hourly wages by 0.308 JOD (p = 0.055).RCT Finance & microfinanceLabeled RemittancesRemittance labeling feature adoption was statistically significant with a 4.2% weekly usage probability (t = 47.701, p < 0.001), averaging 0.054 labeled transfers per week and a winsorized average labeled remittance amount of 687.57 PhP per week (t = 30.389, p < 0.001).RCT Labour & employmentLabor Market Disconnection Heterogeneity in Human Capital ResponseSeverely disconnected jobseekers in the control group exhibited negative baseline human capital investment index scores (-11.84), but cash transfers generated a statistically significant positive effect of +14.30 points (p < 0.05; p < 0.01 for equality test across groups), driven primarily by gains in self-assessed employment prospects. Conversely, less disconnected jobseekers showed a slight negative response (-5.61 points).RCT Labour & employmentLabor Market Displacement EffectAt eight months, untreated job seekers in treated communities were 2.1 percentage points less likely to obtain long-term employment than job seekers in communities where no counseling was offered, and in highly competitive job markets, untreated peers experienced a 7.7 percentage point drop in employment relative to pure comparison areas.RCT Labour & employmentLabor Market Information Provision and Job FairsIn Ethiopia, job fairs corrected distorted beliefs about employment prospects and enhanced job search outcomes for job seekers with strong initial misconceptions. In the Philippines, a job fair sharing overseas labor market information increased the likelihood of seeking employment outside the local region and entering formal sector employment. In Germany, providing information about the job search process increased employment and earnings for workers at risk of long-term unemployment.RCT EducationLabor Market Opportunity Cost PullBroad expansion in low-skill formal export manufacturing jobs substantially raised the probability of quitting upper secondary school for youth on the dropout margin at age 16.Observational Study Labour & employmentEducational Labor Market SegmentationA worker with tertiary education is **7 times more likely** to hold a permanent job and **4 times more likely** to hold a formal job compared to a high school graduate; baseline control group permanent job rates were only 12% overall.Observational Study Labour & employmentLabor Substitution and Foregone EarningsIn Côte d'Ivoire, net participant earning gains accounted for only 53 percent of total public works wages due to foregone lower-paying work. In the Democratic Republic of the Congo, when one family member participated, other household members worked 1.5 percentage points less, contributing to a 9 percent decline in total monthly household earnings.RCT Labour & employmentLabor Supply Adjustment LagMPE is 0.004 in the year of winning (Year 0), drops to -0.056 in Year 1, and stabilizes around -0.10 from Year 2 onward, demonstrating a 1-to-2-year adjustment period.Observational Study Labour & employmentFormal Sector Labor Supply Expansion Without Local Sector DisplacementBusiness process outsourcing employment increased by 4.6 percentage points (p < 0.01) with no statistically significant decline in agricultural labor (-0.008, p > 0.10) or non-BPO paid work (-0.012, p > 0.10), proving total female labor supply expanded from previously inactive populations.RCT EducationLagged Retention Effects of Relational MentoringEnrollment effects were statistically indistinguishable from zero after two semesters (TOT = 0.072) and four semesters (TOT = -0.077), but grew into a statistically significant 25.1 percentage point increase in college persistence by six semesters (TOT, p < 0.10).RCT DevelopmentLand Fragmentation Micro-Climate Risk DiversificationThe number of cultivated land parcels significantly and positively increases the gross value of crop output (IV coefficient = +0.056, p < 0.01;

Off-platform employment probability changed by +0.18 percentage points (p = 0.910 unadjusted; +1.08 percentage points, p = 0.589 adjusted).RCT Methods & evidenceOmnibus Super-Family Index InferenceConstructing standardized family indices confirmed that secondary domains (e.g., total financial expenditure $p = 0.797$, life satisfaction $p = 0.901$) showed no spurious treatment effects, maintaining statistical rigor across multi-domain evaluations.RCT Economics (general)One-on-One Peer MentoringFemale microentrepreneurs in Kenya paired with mentors increased short-term profits by 20%, but these profit gains completely vanished after one year when mentor stipends ended; two additional mentorship studies in Kenya and Ethiopia showed no long-term impact on firm performance.RCT Firms & operationsHierarchical Decision Delays and Operational DowntimeMiddle plant managers lacked financial spending authority to purchase spare parts for broken textile lifts and trolleys, causing basic equipment breakdowns to persist unaddressed and inducing substantial productivity drops.RCT DevelopmentOperational Fidelity Benchmarking in Social Work InterventionsImplementation benchmarking increased student-navigator interaction frequency, directly preceding the emergence of statistically significant six-semester persistence gains (25.1 percentage points TOT, p < 0.10).RCT Labour & employmentOrthogonal Effort-Attention FrameworkEach Rs. 1 piece-rate increase raised output by 0.020 SDs (p=0.042) but had a zero or slightly negative effect on attentiveness (-0.013 SDs, p=0.198; equality test p=0.001), establishing that effort and attention operate via independent mechanisms.RCT EducationOut-of-School Scheduling FrictionScheduling sessions outside normal class hours resulted in a 70.0% zero-attendance rate for cognitive behavioral therapy workshops and a 97.0% zero-attendance rate for supplementary mathematics tutoring.RCT Labour & employmentProgram Outcome Stigma Dominance Over Participation StigmaInterventions addressing job outcome stigmas created large heterogeneous responses ranging from a -15.5 percentage point reduction in applications in low-response groups to positive gains in high-response groups, whereas financial hardship framing produced no statistically significant change in application rates (-2.3 percentage points, p = 0.44) or applicant composition.RCT Economics (general)Extreme Value Top-Coding Truncation ProtocolCapping administrative distributions at the 99th percentile eliminated extreme hiring outliers, ensuring linear treatment effect estimates (+0.047 vacancies, +0.046 hires) reflected representative firm behavior across the sample.RCT Firms & operationsOutsourced Marketing ProfessionalizationSubsidizing small firms to hire or outsource skilled marketing professionals directly improved firm marketing practices and generated business growth more cost-effectively than providing traditional managerial consulting services.RCT Economics (general)Overtime Intercept Constraint ExtrapolationUnconstrained logit models yield an imprecisely estimated marginal value of time of $43.10 (s.e. = 15.90) for 40 vs 45 hours, whereas imposing linear intercept constraints reduces the standard error tenfold, yielding a precise MVT of $21.89 (s.e. = 1.70).RCT Firms & operationsOwner Centralization and Decision-Making Delegation BarriersPlant managers in the US, Europe, and Japan can independently approve capital investments averaging $50,000, whereas owners in developing countries like India, China, and Brazil delegate almost no authority and require owner sign-off on purchases as small as $25.Observational Study Firms & operationsOwner Time Constraints and Procrastination in Process AdoptionFirm directors worked an average of 68 hours per week; owner time scarcity and procrastination rose from causing 3.7% of practice nonadoption at baseline to 14.0% after 9 months as an implementation backlog accumulated.RCT DevelopmentPaired Migrant-Household Dyad SurveyingSuccessfully completed endline interviews with 1,987 migrants and 2,075 target household financial managers, establishing 1,377 fully paired dyads to analyze expenditure shifts against recorded remittances.RCT DevelopmentPalliative Insurance Demand PatternMarginal product of inputs negatively predicts actual insurance purchase in interlinked villages (coefficient = -0.0221, p < 0.01), sum insured (coefficient = -30.91, p < 0.01), and own cash spent (coefficient = -1.050, p < 0.01). Chemical fertilizer use positively predicts uptake (coefficient = +0.177, p < 0.05).RCT EducationParaprofessional Remediation Cost-EffectivenessThe remedial tutor program cost Rs. 107 ($2.25) per student per year and achieved a cost of $0.67 per standard deviation improvement in test scores, making it 5 to 7 times more cost-effective than computer-assisted learning ($15.18 per student per year).RCT DevelopmentParastatal Input Procurement Lead-Time FrictionOver 70% of surveyed smallholder households reported that chemical fertilizer is regularly supplied late, and approximately 40% reported that available input quantities were inadequate for farm needs.Observational Study EducationDecoupling Child Human Capital Investments from Parental Educational DeficitsSchool enrollment increases for young girls in treatment villages (5.0 percentage points overall, p < 0.01) were equally pronounced in households where parents had zero formal education, proving demand-side labor market returns offset parental educational deficits.RCT Labour & employmentPart-Time Labor Scarcity RationalizationBecause the marginal value of time curve transitions rapidly from highly elastic below 30 hours to highly inelastic above 30 hours, the wage range in which part-time employment is optimal is extremely narrow, naturally generating a sparse intermediate hours distribution.RCT Economics (general)Partial-Coverage Co-Payment FundingInflation reduced public voucher coverage from initial full tuition to 56% of average private school tuition by 1998, requiring low-income target families (strata 1 and 2) to make up the remaining 44% in co-payments while maintaining a 15 to 17 percentage point increase in private school enrollment.Observational Study Labour & employmentPartially Directed Search under Behavioral FrictionJobseekers apply to higher-salary jobs at higher rates, but control jobseekers apply to under 0.1% of top-salary quintile matches. Marginal applications induced by phone call initiation match the distribution of inframarginal applications across salary quintiles (p = 0.739), whereas forcing random search via vacancy ordering yields sharply lower interview returns (2.4% vs 6.3%, p = 0.077).RCT Behaviour & psychologyPatient Reporting Reticence from Social ProximityPatients were 7.4 to 10.3 percentage points less likely to file complaints when complaints led to tangible monetary or peer-shaming consequences for providers (a 25% to 33% reduction from the Complaint Box mean of 29.3%), driven primarily by patients who personally recognized health workers participating in the session.RCT EducationPay-for-Percentile Tournament ContractTiered raise brackets (top 10% get 10% raise, 61-90th get 7%, 16-60th get 5%, 3-15th get 2%, bottom 2% get 0%) generated a 0.0918 standard deviation increase in student test scores relative to flat 5% raise controls (p < 0.10).RCT Labour & employmentPay-for-Performance Counseling and Take-Up FrictionOnly 35 percent of job seekers offered intensive counseling enrolled in the program, short-term employment gains at eight months were driven entirely by fixed-term contracts rather than permanent contracts, and all employment advantages disappeared completely after twelve months.RCT Labour & employmentPay Frequency Contract Permanence ProxyExperimentally induced short-term work experience resulted in a negative point estimate on payment frequency (-0.318 ITT, -0.386 IV, p > 0.10), indicating that the observed wage gains occurred through less permanent, daily-remunerated positions rather than permanent monthly roles.Observational Study Behaviour & psychologyPayday-Driven Effort SpikesWorkers exhibiting above-average payday effects were 13.8 percentage points more likely to select positive production targets, selected targets that were 351 fields higher, and after two months were 20.6 percentage points (73%) more likely to select commitment contracts, yielding a 9% output increase when commitment contracts were offered.RCT Economics (general)Payment Mode Equivalence Under Unconstrained LiquidityDynamic labor supply responses over a 10-year follow-up period show statistically indistinguishable trajectory patterns between lump-sum payout recipients and monthly annuity recipients, rejecting severe present bias or binding borrowing constraints.RCT Economics (general)Payoff-Maximizing Task SelectionTreated students were 14.1 percentage points more likely in Sample B during Visit 1 (p < 0.01) and 9.1 to 9.6 percentage points more likely across both samples during Visit 2 (p < 0.05) to select the task difficulty that maximized expected material payoffs.RCT Labour & employmentInsignificance of Pecuniary and Time Search CostsFree callback salience increased applications by only 0.003 percentage points (1/100th of phone call treatment effect, p = 0.017). Offering text-based callback scheduling to eliminate wait time increased application probability by 0.059 percentage points, which is 1/4th the effect of proactive phone call initiation (p = 0.002).RCT EducationPedagogical Process TrackingUnlike material block grants whose gains decayed to 0.02 SD in Year 2, pedagogical tracking interventions demonstrated cumulative second-year learning gains that were larger than initial first-year impacts.RCT DevelopmentPeer-Accompanied Business TrainingWomen trained with a friend were 7 percentage points (117 percent) more likely to take a business loan within four months and 4 percentage points (40 percent) less likely to report their occupation as housewife compared to the control group, accompanied by higher household income and sales expansion. Solo-trained women showed no significant increase in borrowing or sales.RCT Finance & microfinancePeer-Based Selection of MicroentrepreneursEntrepreneurs ranked in the top third by peers achieved monthly returns of 24% to 30% on cash grants (around 3 times the average return of 10% to 11%), and combining observable traits with peer information yielded 38% monthly returns.RCT Labour & employmentPeer Cognitive Evaluation AsymmetryHigh-ability workers accurately predicted referral puzzle scores (coefficient = 0.190, p < 0.05), corresponding to an 0.8 standard deviation performance difference, whereas low-ability workers showed no statistically significant predictive accuracy (coefficient = 0.025, p > 0.10).RCT Crime & justicePeer Group Composition Constraints in Program TargetingWhile 100% of crime reduction cost savings ($652–$1,250 per participant) stem from the 3% at-risk subgroup, universal open-enrollment programs embed at-risk youth in a broader peer group where 97% of participants have no criminal record, preventing adverse peer contagion.Expert Theory EducationPost-Randomization Peer Compositional StabilityAssigned teacher effectiveness showed no statistically significant relationship with peer baseline math scores (coefficient = 0.246, SE = 0.164) or other peer traits; joint hypothesis p-values were 0.405 for grades 4–8 and 0.321 for high school, proving post-randomization peer stability.RCT HealthPeer Disclosure Accountability MechanismPeer Disclosure increased provider reciprocity (returned-received ratio) by 42 percentage points relative to the Complaint Box control (p = 0.048 wild bootstrap), representing a 40% increase over the control mean of 1.039, performing as effectively as direct Monetary Penalties (33 percentage point increase).RCT EducationPeer Effects Overcontrolling in Value-Added ModelsThe component removed by peer effect controls predicted student achievement after random assignment with a coefficient of 1.150 (p < 0.01, SE = 0.336), proving it contains causal teacher effectiveness. In contrast, the component removed by individual baseline score controls yielded a coefficient of 0.047 (SE = 0.042), showing baseline score controls successfully remove non-teacher sorting noise.RCT DevelopmentVideo-Based Peer Modeling in Financial Literacy PedagogyCombining peer video motivation with concrete goal-setting generated a 19 percentage point increase in labor market participation (p < 0.01) and a 17 percentage point increase in business discussions with family (p < 0.05) among moderately restricted women.RCT Finance & microfinancePeer Monitoring Risk ConstraintPeer monitoring within microfinance groups incentivizes borrowers to select safer, lower-return projects to minimize peer disapproval and social penalties.Expert Theory DevelopmentLocal Geographic Distance and Business Practice Non-ContagionMinimum distance to a consulting tailor had no statistically significant effect on business practice adoption by control tailors (coefficient = -0.0304, p > 0.10), and the number of consulting tailors within 0.5 km similarly showed no significant spillover effect (coefficient = 0.00779, p > 0.10).RCT Labour & employmentPeer Productivity SpilloversSitting near a peer with above-average productivity increased an individual worker's output by 5%, driven primarily by an increase in total hours worked rather than speed per unit of time, and increased the worker's probability of choosing commitment contracts by 5 percentage points.RCT Firms & operationsPeer Role Model IntegrationIncreased monthly household income by US$30–US$50 (~15% increase) 1 year post-program at 1/10th the cost of individual consulting, while significantly raising rates of tax registration and seed fund applications.RCT Behaviour & psychologyPeer Saturation and Information DiffusionEvaluates whether achieving a 75% training saturation threshold in local administrative units increases social spillover effects and program uptake compared to a 25% threshold.RCT EducationPell Grant Completion Gap ParadoxFederal Pell Grants provided $30 billion in aid in 2015 with over one-third going to community college students (38% with zero out-of-pocket tuition), yet low-income college completion gaps widened over the same period.Observational Study Economics (general)Perceived Contract NoiseA 1 standard deviation increase in perceived contract noise decreases teacher time worked by 13 hours and decreases student test scores by 0.20 standard deviations.RCT Behaviour & psychologyPerceived Marginal Product of EffortRaising perceived effort productivity caused treated students to be 8.5 percentage points more likely in Sample A (p < 0.01) and 12.9 percentage points more likely in Sample B (p < 0.01) to consistently choose challenging, high-reward tasks across all five rounds compared to control baseline rates of 25% and 17%.RCT Labour & employmentPerformance-Based Incentive SystemsIntroducing worker and manager incentive systems directly increased worker efficiency and attendance, contributing to a 9.4% overall increase in plant output and a 16.6% productivity increase in the first year.RCT EducationPerformance-Contingent Voucher Renewal IncentivesConditioning voucher renewal on passing grades reduced grade repetition rates by 5.3 to 6.3 percentage points and increased 8th-grade completion rates by 8.7 to 9.4 percentage points.RCT Firms & operationsStructured Worker Performance and Attendance Incentive SystemsAt baseline, only 21.4% of treatment plants had performance reward systems for non-managerial staff; implementing performance and attendance incentives combined with visual efficiency tracking contributed to a 9.4% increase in fabric weaving output and reduced worker absenteeism.RCT DevelopmentPerformance Monitoring in Education RemittancesDirect payment with monitoring increased total remittances by 103.0 € over the no-label mean of 614.6 € (p < 0.01), but showed no statistically significant incremental gain over direct payment without monitoring (107.4 € vs 103.0 €, p = 0.4771).RCT DevelopmentPeril Mismatch in Index Insurance Design36 out of 120 Kebeles (30%) were excluded from the study because rainfall deficit was not the primary hazard, as frost and flooding predominated and lacked suitable index data.Observational Study HealthDifferential Belief Persistence Between Personal and Peer Health InformationWhile individual status learning effects decay within two years (Thornton 2012), community-level testing information produces statistically significant downward belief adjustments and condom reductions two years post-intervention (p < 0.01).Observational Study EducationPersistent Student Baseline Sorting CovarianceThe signal standard deviation of persistent within-school student baseline sorting was 0.297 in math and 0.300 in ELA for randomized MET teachers, compared to 0.437 in math and 0.440 in ELA for non-randomized MET school teachers, proving that structural student sorting was substantial prior to experimental intervention.RCT Economics (general)Personal Initiative TrainingMicroentrepreneurs in Togo who received personal initiative training increased adoption of business practices by 5.4 percentage points and boosted firm profits by 30% relative to the comparison group 2.5 years after training.RCT Economics (general)Personal Stigma Invariance in Behavioral InterventionsPersonal stigma messaging produced no statistically significant average treatment effect (ATE = +0.025, p > 0.10) and no statistically significant treatment effect difference between the top (+0.073) and bottom (+0.047) predicted response groups (p = 0.756).RCT Labour & employmentHigh-Caseworker Personalised Employment Model for Homeless IndividualsParticipants assigned to personalized support worked approximately 14 additional days over a 6-month follow-up period according to administrative records (an 80% increase over comparison), were 8 to 10 percentage points more likely to report employment in surveys, and demonstrated marked improvements in housing stability, safety, and life satisfaction.RCT Labour & employmentPersonalized In-Person Formalization AssistanceIndividualized in-person assistance significantly increased formalization and tax compliance in Rio de Janeiro and Bogotá, whereas virtual messaging and group workshops produced zero statistical impact on formalization rates.RCT DevelopmentPesticide Input Risk ComplementarityProviding rainfall insurance increased pesticide investments for cash crops by 0.932 log points (p < 0.05) and increased the likelihood of positive pesticide usage by 5.4 percentage points (p < 0.05), representing the only individually statistically significant input category shift among disaggregated agricultural inputs.RCT Finance & microfinancePhase-Based Parametric Monsoon TriggersInsurance contracts define payouts using linear deficit functions between a crop-vital rainfall threshold ("strike") and a catastrophic crop-failure threshold ("exit", e.g., 0–10 mm), paying up to a Rs. 1,000 maximum policy cap.Expert Theory Firms & operationsPhased Pilot Implementation Strategy for Belief UpdatingNonadoption driven by incorrect profitability beliefs dropped from 34.6% to 15.2% over 9 months in treatment plants as pilot demonstrations built owner trust, enabling the rollout of more complex human resource and incentive practices.RCT Methods & evidencePhased Treatment Enablement ProtocolThe phased enablement protocol effectively isolated non-complying recruits without introducing observable baseline trait imbalances (p > 0.10 across balance tests on gender, age, income, and remittance history).RCT Labour & employmentPiece-Rate Incentive Effect vs. Worker SelectionRaising the piece rate by 10 MWK increases output quantity by 0.18 to 0.26 units sorted per day from a baseline mean of 7.35 units (p < 0.01), establishing a positive incentive effect. Controlling for actual piece rate received, reservation wage (minimum willingness to accept) exhibits a slightly negative or zero relationship with output quantity (a 10 MWK increase in minimum WTA lowers daily output by 0.20 to 0.30 units in random effects models, p < 0.05).RCT Economics (general)Piece-Rate Financial Incentive Orthogonality to Promotion TournamentsRegression analysis showed that interaction terms between short-term piece-rate bonuses and meritocratic promotion incentives on household visit output were statistically non-significant, confirming that career advancement tournaments function independently of short-run cash incentives.RCT Economics (general)Placebo Validation of Information Treatment MechanismsDisclosing official supervisor salary to workers with accurate baseline beliefs produced no statistically significant change in household visits under either meritocratic (+1.308 visits; p = 0.608) or non-meritocratic (-0.968 visits; p = 0.608) promotion regimes, ruling out attention or demand artifacts.RCT Labour & employmentPlan-Driven Workplace Stress MitigationTreatment loan officers were 8 percentage points more likely to increase or maintain high planning levels (p < 0.10) and experienced a 5.8 percentage point reduction in the percentage of time feeling stressed at work (p < 0.10, OLS coeff = -0.058), alongside a 5 percentage point increase in job satisfaction (probit coeff = 0.298, p < 0.10) and a 6 percentage point increase in compensation satisfaction (probit coeff = 0.358, p < 0.10).RCT Labour & employmentPoint System Selection InefficiencyRecent immigrants experienced an unemployment rate of 10.4% versus 5.9% for native-born workers. Median earnings for recent immigrants were 36% lower than native-born workers ($21,000 vs. $33,000), and controlling for educational attainment expanded the relative wage gap to 48% lower earnings, despite 60% of recent immigrants holding undergraduate degrees compared to 20% of native-born peers.Observational Study Economics (general)Policy-Relevant Treatment Effect vs. Microeconometric BiasAt experimental intensity ($\tau = 0.3$), participants enjoyed a 5.4 percentage point higher monthly matching rate than nonparticipants (0.245 vs 0.191). However, the policy-relevant treatment effect under full rollout ($\tau = 1.0$) was only 0.3 percentage points (0.208 vs 0.205), proving standard microeconometric trials overestimate nationwide impact by over 1,700%.Observational Study Economics (general)Policymaker Targeting Efficiency Dilemma Under Stigma MitigationStigma alleviation pitches systematically selected applicants who were older (+2.79 years, p = 0.02 in Exp 2), richer (+0.209 SD Lasso index, p < 0.01 in Exp 1), and already working (+7.0 percentage points, p < 0.05 in Exp 1), creating a trade-off between maximizing employment returns versus equity-focused targeting.RCT Labour & employmentPortable Vocational CertificationVocational trainees received significantly more job offers and maintained higher long-run employment rates compared to firm-provided apprentices because trainees could better certify their skills to new employers.RCT Finance & microfinanceDebt Maturity Portfolio Effect vs Income EffectThe net present value income effect accounts for only Rs 10,000 (roughly 42%) of the observed Rs 23,600 long-run capital stock differential between grace period and regular clients, proving that enabling illiquid investment choice (the portfolio effect) drives the majority of economic gains.RCT Behaviour & psychologyPositional List-Order Choice BiasExactly 31.3% of control group applications and 31.1% of treatment group applications were directed to the first vacancy mentioned on the call or text message, despite first-listed vacancies comprising only 22% of all available matches.RCT Labour & employmentPost-Formalization Registration Non-Renewal (Formalization Churn)Personalized assistance initially increased business formalization, but the effect dissipated completely over time as newly formalized firms chose not to renew registration after experiencing zero gain in sales or profits.RCT Society & networksPost-Indexed Communication Lag ParameterizationPeer effect estimates for submission and quality stabilize when the communication lag threshold reaches $\tau \ge 80$ intermediate sentences, converging directly to the unbounded benchmark ($\tau = \infty$, $\beta = 0.533, p < 0.01$ for submission; $\beta = 0.537, p < 0.01$ for extensive quality).RCT Behaviour & psychologyPost-Intervention Behavioral RelapseFollowing program termination, the post-intervention treatment dummy returned to zero/statistically insignificant levels across goal completion, gap indicator (-5.16, p > 0.10), and biweekly productivity (0.387, p > 0.10), proving that productivity gains were driven strictly by active reminders rather than permanent habit formation or career concerns.RCT Society & networksPost-Migration Mobility RestrictionsMigrant female workers relocating over 100 kilometers reside in factory hostels under movement restrictions that curtail social network building.Observational Study Labour & employmentPost-Employment Retention and Wraparound SupportsRetention and case management supports enabled sectoral program trainees to work 1.3 months longer (a 9.6% increase, p < 0.01) over two years and achieve a 10 percentage point increase in jobs offering benefits (57% vs 47%, p < 0.01) relative to control group members.Expert Theory Labour & employmentPost-Probation Match DurabilityFirms receiving combined advertising and verification services were 11 percentage points (73 percent) more likely to still employ their online portal hire 6 months post-posting compared to comparison firms.RCT Labour & employmentThe Post-Program Labor Market Dissipation EffectSYEP participation increased in-program job probability by 71 percentage points and yielded $1,085 in program earnings ($876 net gain after $209 crowd-out of alternative income), but reduced subsequent earnings by ~$100 annually across the three post-program years. OSC+ increased program-summer formal employment by 85 percentage points (from a 12% baseline) and earnings by ~$1,000, but exhibited zero statistically significant impact on post-program employment, earnings, grade point average, or college enrollment.RCT Labour & employmentPost-Program Self-Employment TransitionPublic works program participants worked 16 percent more days in self-employment compared to non-participants, measured more than a year after program completion.RCT Crime & justicePost-Program Violence Reduction via Workplace Social-Emotional LearningParticipation in One Summer Chicago Plus (OSC+) reduced violent crime arrests one year after random assignment by 6.4 arrests per 100 youth from a baseline of 18.3 arrests per 100 youth (a 35% reduction), with the bulk of the decline occurring after the program ended. OSC+ increased property crime arrests over two years by 5.8 per 100 youth from a baseline of 12.7 (a 45% increase). Estimated social benefits from violence reduction were nearly six times larger than program costs.RCT Labour & employmentPost-Programme Negative ImpactEmpirical estimations revealed non-positive or negative exit hazard coefficients following program completion across multiple program types (e.g. vocational training post-completion coefficient -0.49 for control group members in Storstrøm).RCT Labour & employmentPost-Training Livelihood AssistanceEmpirical findings are forthcoming as the evaluation is ongoing, with follow-up surveys planned via phone 3 months post-intervention.RCT Labour & employmentPotential Experience Measurement BiasNonexperimental wage returns relying on potential experience proxies require approximately 10 years of estimated potential experience in Malawi to match the wage gain produced by 5 days of actual measured work experience, demonstrating that potential experience drastically underestimates true per-day returns while overstating accumulated work history.Observational Study DevelopmentPoverty Productivity TaxBelow-median wealth workers experienced a 0.204 SDs (13.0%) output increase (p=0.003) and a 0.133 SD decrease in attentional lapses (p=0.037) following cash receipt, whereas above-median wealth workers showed virtually zero productivity response (+0.014 SDs, p=0.819).RCT Labour & employmentPre-Experimental Out-of-Sample Predictive ProfilingThe historical model successfully stratified the experimental sample into 1,688 high-employability ($\le 6$ months) and 2,475 low-employability ($> 6$ months) individuals, correctly identifying 87% of long-duration cases in baseline data without endogenous stratification bias.RCT HealthPre-Sexual Debut Curriculum Timing StrategyDelivering the curriculum to mostly inexperienced 15-year-olds produced a 0.38 SD increase in overall sexual knowledge, a 0.17 SD increase in positive attitudes, and a 55% increase in condom voucher redemption without increasing self-reported sexual activity rates.RCT Labour & employmentPrecarious Employment Path DependencySecuring a permanent job after 1 year accounts for 23% of the 4-year earning gains, while 1-year earnings account for 56% (62% joint); holding a temporary or informal job after 1 year yields zero long-term wage gain compared to remaining unemployed.RCT DevelopmentPredictable Lean-Season Liquidity ShortfallsCasual laborers secured wage employment on average only 1.9 days per week during the lean season, with 86% reporting being worried or very worried about finances, 71% holding outstanding debt, and 66% unable to access Rs. 1,000 for emergencies.Observational Study Economics (general)Preference-Based In-Group Price DiscountingBuyers received a discounted price when randomly matched with a wholesaler from their own ethnic group, but sellers did not reduce advance payment demands for co-ethnics.RCT EducationParental Preference Heterogeneity in School ChoiceMean preference for school test scores ranges from 1.461 to 2.714 among non-lunch recipients compared to 0.102 to 1.444 for lunch recipients. A 1 standard deviation increase in school test score increases choice odds by 331% for white non-lunch elementary families. African American parents face a tradeoff where choosing high-scoring schools requires sacrificing preferences for majority same-race schools, preferring 80% black over 35% black schools by 10% to 70%.Observational Study Labour & employmentPrerequisite Criteria Pre-SelectionTreated firms experienced a 122% increase in vacancies assigned the prerequisites pre-selection service (0.028 increase over a 0.034 control mean, p < 0.01), where counselors co-defined 1 to 5 unobservable screening criteria with employers.RCT Labour & employmentReinforced Pre-Screening and Filtering ServicesVacancies in treated firms experienced a 58% increase in pre-screening and filtering service usage (3.4 percentage points over 5.8% control mean, p < 0.01) and a 57% increase in private listings, leading to a 39% reduction in direct jobseeker application volume (2.67 fewer applications, p < 0.01) and 0.84 fewer firm-initiated candidate searches (p < 0.01).RCT Behaviour & psychologyPrescriptive-Descriptive Norm Disconnect ActivationPro-transgender participants made supportive statements 2.5 times more frequently than anti-transgender statements during discussions, relying on moral arguments regarding rights and equality.

In Year 11, participant employment reached 83.8% compared to 73.7% in the control group (a 10.1 percentage point increase, p < 0.01), representing the longest-sustained earnings gains in US workforce evaluation history.RCT Labour & employmentService Provider Incentive Alignment in Job CounselingIn France, private providers achieved lower employability outcomes than public employment services because fee structures incentivized maximizing participant volume over job fit. In Switzerland, private providers generated higher short-term placements, but long-term employment outcomes deteriorated because contractors prioritized rapid placement over durable employment matches.RCT Behaviour & psychologyProvider Retaliation Threat DeterrenceThe threat of provider retaliation muted provider reciprocity increases from 42 percentage points down to 26 percentage points relative to the Complaint Box control (a reduction from a 40% increase to a 25% increase over the control mean of 1.039) and suppressed patient complaint card intensity from 1.053 extra cards down to 0.190 cards (p = 0.033 for difference in card intensity between PD and PD-R).RCT EducationProximity Friction and Transportation Zone ConstraintsCommute distance imposes significant negative utility across all student demographics (lognormal distance mean parameters of -0.235 to -0.488 across middle and elementary subgroups). Guaranteed busing within a designated Choice Zone increases choice utility by 1.213 to 2.170 logit points, offsetting the disutility of an additional 3.5 to 5.0 miles of driving distance.Observational Study Labour & employmentPseudo-Contractual Monitoring Ritual80% of surveyed job seekers reported that the integration agreement served as a reminder of search obligations, 78% viewed it as a monitoring tool, and 74% of caseworkers confirmed using it to control search efforts; the intervention operated independently of participation in other active labor market programs or meeting frequencies.Expert Theory HealthTreatment-Induced Work Time ReductionParticipants in the standalone Psychiatric Care group reduced work time by 5.4 hours per week (a 10 percent decrease) during the intervention, with no statistically significant increase in overall earnings.RCT Economics (general)Psychological Costs of Application InitiationProactive phone call initiation increased the job application rate by 600% (from 0.185% to 1.507% of matches, effect = 0.01322, p < 0.001) and increased the interview invitation rate by 550% (from 0.012% to 0.090% of matches, effect = 0.00078, p < 0.001).RCT Economics (general)Psychological Poverty TrapAlleviating financial strain via early wage payments increased production by 0.27 plates per hour (a 7 percent increase) and high attentiveness by 7.7 percentage points (a 17.1 percent increase), establishing that cognitive distraction from financial distress actively suppresses labor efficiency.Expert Theory Firms & operationsPsychosocial Health-Productivity LinkageLongitudinal tracking of individual production line output alongside standardized psychological evaluations to determine the direct economic returns of mitigating loneliness.RCT Labour & employmentPsychosocial Value of EmploymentParticipants randomly assigned to receive paid work experienced significantly stronger psychological and mental health benefits compared to participants receiving the exact same cash amount without work.RCT Labour & employmentIntegrated Psychosocial Therapy and Certified Vocational TrainingThe program significantly enhanced personal autonomy, reduced participants' risk of experiencing mental health problems, increased frustration tolerance and problem identification skills, and expanded job search strategies and perceived employment probability, despite showing low completion rates (25%) and no immediate short-term employment gains.RCT Labour & employmentPublic Early Childhood Care ProvisionFree early childhood education significantly reduced the post-motherhood spike in female informality, helping address the 76.4% informal contract rate among Brazilian domestic workers in late 2023.RCT Policy & public sectorPublic Cost-Benefit Valuation of Policy RegimesThe intensified activation policy regime generated a net societal economic value of €2,000 per exposed unemployed individual, excluding macro general equilibrium effects.Observational Study Finance & microfinanceTargeted Microfinance Risk SubsidiesA targeted public subsidy of Rs 150 per borrower renders microfinance lenders indifferent between classic and grace period contracts at standard 17.5% APR interest rates, generating an estimated annual social return on public capital of 178% based on an average monthly profit gain of Rs 287 per client.Expert Theory Labour & employmentPublic Employment Referral Quality and Systemic FrictionNational usage of SINE among Brazilian job seekers fell from 3.81% in 2012 to 1.81% in 2022. While receiving a job referral through SINE increased overall hiring probability, it resulted in a statistically significant wage reduction compared to workers' previous employment due to the system's inability to capture high-quality private vacancies.Observational Study Labour & employmentPublic Intensive Job Search CounselingAssigned personal advisors to maximum 40 clients for weekly meetings over six months at an estimated cost of €657 per client. Increased exit rate to employment by 50% within six months (a 10.2 percentage point increase from a baseline of 20.7%).

In India, survey completion after unsatisfying wage hikes reduced quit likelihood by 20% (0.23 percentage points).RCT Labour & employmentUrn-Ball Matching Function with Elastic Search EffortThe urn-ball functional form micro-founds crowding-out externalities, yielding structural elasticity estimates where increased search intensity of treated workers directly depresses the contact rate per unit of search effort for non-treated workers.Expert Theory Labour & employmentUrn-Ball Search Coordination FrictionsIncreasing application intensity per worker initially reduces search friction but eventually yields diminishing marginal returns due to severe application clustering, capturing how nonparticipant matching rates drop from 18.2% to 16.0% under full activation ($\tau = 1.0$).Expert Theory Economics (general)Utility-Bill Stratification TargetingMandatory utility bill stratification restricted participation to poor households, resulting in 53.5% of vocational voucher applicants residing in the poorest neighborhood tier in Bogotá.Observational Study Labour & employmentVacancy Competition Non-CongestionShifting a jobseeker from the 25th to the 75th percentile of exposure to treated competitors changed control group interview probability by +0.006 percentage points (p = 0.589) and treated group probability by -0.011 percentage points (p = 0.511).RCT Labour & employmentVacancy Drafting and Legal Compliance SupportFree public vacancy drafting support provided legal compliance verification, salary transparency guidelines, and anti-discrimination checks across treatment firm postings, though overall implementation rates for standalone drafting support remained small compared to pre-screening services.RCT EducationValue-Added Extreme Outlier Trimming and Anomaly DetectionIn English language arts, including an extreme outlier teacher with a 1.666 SD value-added swing dropped the predictive coefficient to an imprecise 0.375 (SE = 0.264); trimming the top 1% restored the ELA coefficient to 0.697 (p < 0.01, SE = 0.213) and overall composite predictive coefficient to 0.955 (SE = 0.123).RCT EducationRank-Based Van Der Waerden Score StandardizationStudents were ranked based on raw scores and mapped to standard normal quantiles (mean 0, SD 1). This eliminated cross-district scale artifacts while preserving relative performance ranks across 6 distinct testing regimes.RCT Labour & employmentVertical versus Horizontal Pay Inequality Incentive DichotomyDisclosing steep vertical pay progression generated strong incentive effects (+23% visits; p < 0.05) under meritocracy but negative morale effects (-27% visits; p < 0.01) under non-meritocracy, demonstrating that vertical pay gaps operate through dynamic career tournament mechanics rather than horizontal peer fairness comparisons.RCT Behaviour & psychologyVicarious Deliberation Spillover in Passive ListenersPassive listeners in the 2-person discussion arm increased their selection of transgender workers by 13 percentage points relative to control, capturing roughly 76% of the 17 percentage point gain observed in fully active 3-person discussions.RCT Labour & employmentVideo-Guided MGNREGS Navigation and TrainingBaseline figures indicated that while three-quarters of study women wanted to work under MGNREGS, majorities lacked operational knowledge regarding work requests and direct deposit configuration prior to intervention.RCT Labour & employmentVillage Labor Market Clearing MechanismCross-village labor commuting accounts for less than 8% of total agricultural labor days, confirming that village labor markets clear locally and driving equilibrium daily wage shifts of up to 33% depending on weather state and insurance density.RCT Labour & employmentOpportunity Cost of Vocational TrainingShort-term labor earnings in the treatment group fell by 10,494 FCFA/month (-25%, p < 0.001) due to reductions in wage work (-6,414 FCFA) and self-employment (-6,381 FCFA). The monthly program stipend of 10,213 FCFA fully offset these forgone earnings, resulting in zero net change in total short-term income.RCT DevelopmentPrice Discount Voucher Discontinuity EffectUnsubsidized uptake was exactly 0% among study subjects receiving no voucher. Receiving a voucher increased insurance purchase probability by 34.4% to 38.0% (p < 0.01), with only 21% of buyers contributing any personal cash beyond the voucher value.RCT Economics (general)Voucher Non-Portability Identification StrategyAdministrative restrictions resulted in fewer than 20% of transferring students retaining their vouchers; consequently, 59.6% of voucher winners who applied to vocational schools remained in vocational schools 3 years later compared to only 42.6% of lottery losers.RCT Labour & employmentWage Framing Invariance (Average vs. Marginal)Estimated marginal values of time are statistically indistinguishable between average wage framing ($12.00, s.e. = 1.50) and explicit marginal wage framing, confirming that structural framing does not bias applicant labor supply evaluations.RCT Economics (general)Wait-List Deferred Residential MobilityApplicants postponed moves during the wait-list period and increased moves after receiving a voucher offer, resulting in a statistically insignificant total address difference (0.036 ITT, p > 0.05).RCT Behaviour & psychologyWealth-Differentiated Sanction Sensitivity in ReportingWealthier patients were significantly more willing to file complaints when reports generated monetary penalties for providers compared to poorer patients (interaction coefficient = +0.076, p = 0.045), whereas lower-wealth patients showed heightened reticence when complaints carried tangible consequences.RCT DevelopmentWealth-Independent Insurance-Induced Risk-TakingInteracting the insurance treatment with landholdings or the principal component wealth index yielded statistically insignificant interaction coefficients for cash crop investment probability, cash crop expenditure, and cash crop cultivated area.RCT Economics (general)Weather-Shock Selection CorrectionOne additional day of rainfall during the 3-day window reduced participant return probability by 20.7 percentage points (p < 0.01, chi-squared > 12.6), providing a valid instrument that eliminated non-response selection bias without affecting indoor cognitive task scores.RCT Economics (general)Welfare Contrasts in Policy ChoiceContrast $\Delta_1 = 0.002$ (95% CS: [0.000, 0.004]), showing negligible in-sample adaptive gain due to muted 6-week treatment effects. Contrast $\Delta_2 = 0.017$ (95% CS: [0.001, 0.034]), demonstrating a 35% gain in employment for the optimal targeted policy over control. Contrast $\Delta_3 = 0.006$ (95% CS: [-0.015, 0.027]), showing half the gain for an un-targeted policy.RCT Labour & employmentWelfare Reversal in Large-Scale Policy RolloutWhile a naive microeconometric evaluation calculates a false positive net return of 4,094 DKK (~550 EUR) per participant, structural simulation proves social welfare is maximized at only 20% treatment intensity and drops by 0.13% under full (100%) rollout, while government UI program expenditures are minimized at 30% intensity.Expert Theory Economics (general)Welfare Stigma Neutrality in Developing EconomiesExplicit financial hardship framing caused no statistically significant change in application rates (-2.3 percentage points, SE = 0.030) or Lasso-based demographic composition relative to standard subsidized control.RCT Labour & employmentWhite-Collar Service Wage Premium AsymmetryStarting BPO salaries for entry-level candidates with basic English and computer skills ranged from 5,000 to 10,000 INR ($110-220 USD) per month in 2003, representing 200 percent of the average pay for non-BPO workers with similar educational attainment.Observational Study DevelopmentWhite-Collar Comparative Advantage and Stigma ReductionThe recruiting treatment increased reported community acceptability of post-marital female work away from home by 4.3 percentage points (p < 0.05) relative to a control group mean of 7.1%, while national BPO call centers maintain a female worker share of 45% in India (and 69% globally).RCT HealthLay-Delivered WHO PM+ Intervention in ManufacturingProgram evaluation is actively ongoing; baseline data shows loneliness among young migrant factory workers is as severe as levels in older adults aged 32 to 47 and chronically ill individuals.RCT Finance & microfinanceWillingness to Pay for Debt Flexibility40.0% of existing microfinance clients were willing to pay an interest rate of 17.5% APR or higher for a grace period contract, and 30.8% of non-clients expressed willingness to pay above the MFI break-even threshold of 38.0% APR.Observational Study Labour & employmentWindfall Effect on Youth Training Supply25.9% of formal apprentices substituted out of traditional informal apprenticeships ($\omega = 0.259$, p < 0.001); overall youth entry into any apprenticeship increased by 52.8 percentage points despite this 18.5 percentage point windfall drop.RCT Economics (general)Application Window Timing DecayEach additional day between notification and application deadline reduced the phone-call treatment effect on job application probability by 0.072 percentage points (p < 0.001).RCT EducationRandom Effects and Fixed Effects Value-Added EquivalenceTeacher effect estimates generated from random-effects specifications controlling for classroom section-mean covariates are highly correlated with teacher fixed-effects specifications because the vast majority of student baseline variance exists within classrooms rather than between classrooms.Observational Study Methods & evidenceWithin-Firm Spillover Dilution ControlRemoving multi-establishment corporate branches prevented internal information spillovers, maintaining orthogonal treatment variation across 7,438 independent establishments.RCT Labour & employmentWithin-Occupation Task IntensificationNon-routine analytical tasks increased significantly within sectors (+0.139 standard deviations, p < 0.01), driving a significant within-sector reduction in overall routine task intensity (-0.175 standard deviations, p < 0.05).RCT Methods & evidenceWithin-Participant Nested Choice ArchitectureIsolating features revealed that soft labeling accounted for a 15% increase (93.66 €) over the basic remittance baseline of 614.6 €, while adding direct payment added only an incremental 2.2% (13.74 €), demonstrating diminishing marginal returns for hard commitment features.RCT Labour & employmentWorkAdvance Sectoral Advancement ModelPooled earnings across all four providers increased by $1,945 (a 14% increase, p < 0.01) in Year 2 and $2,716 (a 11.5% increase, p < 0.01) in Year 5. Mature providers yielded higher impacts; Per Scholas participants achieved a 41 percentage point increase in IT sector employment in Year 2 (61% vs. 20%, p < 0.01) and a 19.6% long-term earnings gain in Year 6 (p < 0.01).RCT Firms & operationsWorkplace-Based Firm ConsultingIn contrast to modest results from general microentrepreneur classroom training, workplace-based consulting and customized business training for larger firms consistently improved managerial best practices and increased total business profits.RCT Methods & evidenceWorkplace Batching and Peer Isolation ProtocolControl group workers showed zero output decline on Day 9 after witnessing Wave A treatment workers receive early cash payouts, confirming the absence of relative fairness spillover.RCT Labour & employmentWorkplace Environmental Hazard and Microclimate MitigationMitigating physical microclimates via heat-reducing LED lighting, lowering machinery noise, facilitating short afternoon naps, and reducing pollution exposure significantly increased employee cognitive function and daily labor productivity.RCT Labour & employmentWorkplace Network Expansion for Family Planning InformationBaseline state survey revealed 40% female employment compared to 78% male employment; evaluation measures whether job expansion builds social networks that make family planning accessible and affordable.RCT Methods & evidenceWorst-Case Variance Bounded SamplingSetting lambda = 0.00125 guarantees a worst-case standard error of 0.05 for treatment contrasts and a statistical power >= 0.80 for detecting effect sizes of 0.124 across N = 4,000 participants, enforcing a minimum assignment probability floor of 0.05 per treatment arm.Expert Theory Labour & employmentYearUp Intensive Youth Sectoral Training ModelBy Year 3, participant annual earnings grew by $7,011 (a 40% increase, p < 0.01), driven by a 33 percentage point gain in IT sector employment (37% vs. 4%, p < 0.01) and a 9 percentage point gain in financial services (23% vs. 14%, p < 0.01). By Year 5, quarterly earnings remained $1,857 higher (a 33.5% increase, p < 0.01), generating $1.66 in public benefit per $1 spent ($15,349 net benefit per participant).RCT EducationYouth Engagement Pre-ConditioningIntegrating structured youth engagement exercises enabled lay teacher-facilitators to build an atmosphere of trust, with qualitative surveys showing nearly 100.0% teacher willingness to participate in future implementations.Observational Study
