The findings
Ability-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.RCTAbility-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.RCTActivation 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.RCTActual 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 StudyAdvance 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).RCTAge-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 StudyAlgorithmic 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.RCTAlgorithmic 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.RCTCost-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.RCTActive 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.RCTAnglo 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%).RCTAnglo-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 StudyAbsence 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.RCTAnonymized 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.RCTAsymmetric 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.RCTAuxiliary 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).RCTBaseline 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.RCTSubstitutability 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.RCTBaseline 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.RCTBelief 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).RCTSubjective 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.RCTVoluntary 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 StudyEx-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 TheoryBlind 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 TheoryBPO 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.RCTComparative 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).RCTBroad-Based Wage Distribution CDF ShiftWage gains persisted consistently across all 8 post-intervention months ($1 to $6 per day increase across individual months), displaying a rightward shift of the entire daily wage CDF rather than earnings concentration among a few top earners.RCTCalibrated Labor Supply Elasticity of Housing SubsidiesCalibrated utility parameters ($\mu = 0.7285$) yield an income elasticity of -0.09 and a compensated wage elasticity of 0.15.RCTCandidate 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).RCTCandidate 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).RCTCareer 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).RCTCaseworker 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.RCTCaseworker 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).RCTMulti-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).RCTCasual-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.RCTCausal 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.RCTDual 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.RCTMobile-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.RCTChild 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.RCTCohort 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 StudyMacroeconomic 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 StudyConstant 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).RCTContract 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.RCTContract 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.RCTCombined 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.RCTAsymmetric 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.RCTCounselor 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.RCTCounselor 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.RCTCredential 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.RCTCross-Gender Asymmetry in Human Capital and Labor Market EffectsTreatment had zero statistically significant impact on men's BPO employment (0.003, p > 0.10), total paid employment (-0.006, p > 0.10), enrollment in school/training (0.003, p > 0.10), or likelihood of marriage (-0.006, p > 0.10).RCTCustomised Employment Methodology for Disabled Job SeekersThe Customised Employment Methodology increased weekly working time by 2.3 hours (a 73% increase over the comparison group) and increased accumulated work contracts by 0.14 (a 45% increase), while enhancing participation in training, volunteering, social inclusion, and overall well-being.RCTDeepTech Integrated Skill SignalingProgram historical data indicates 50% to 70% of trained participants successfully secure STEM jobs at major tech companies; RCT impact evaluation on earnings and placement is ongoing.RCTDemand-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).RCTDemographic 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 StudyDigital 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.RCTOnline 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.RCTBundled 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.RCTDigital 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.RCTFinancial 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).RCTDirect 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.RCTDiscontinuous 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).RCTDisplacement 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).RCTDisplacement-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.RCTDistributional 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 $4.19 daily wage increase (p < 0.05) represents broad-based income growth rather than outlier-driven mean distortions.RCTDisutility of Leisure and Wage Discipline EffectMandatory participation eliminates non-market leisure time value ($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%.RCTDominated 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%.RCTDouble-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.RCTDriver'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).RCTDual-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.RCTDual 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 TheoryDual-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.RCTIntegrated 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.RCTDual-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.RCTDual-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 StudyDuration 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 StudyDynamic 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.RCTEarly 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).RCTEducated 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 $210 per 3-month period prior to intervention.Observational StudyEducation-Driven Apprentice Self-SelectionFormal apprentices were 47.5 percentage points less likely to have no education (p < 0.0001), 34.8 percentage points more likely to have completed primary education (p < 0.0001), 2.10 years older on average (p < 0.0001), and 23.0 percentage points more likely to aspire to formal wage employment (p < 0.0001) compared to traditional apprentices in control firms.RCTEducational Heterogeneity in Information FrictionsHigh-school educated jobseekers doubled their permanent employment rate from 5.8% to 11.6% (ITT = +5.76 percentage points, p < 0.05) and increased formal employment by 45% (+4.82 percentage points, p < 0.10), driven by an 8.7% reduction in reservation wages (p < 0.10); post-secondary jobseekers showed no statistically significant change in permanent employment (-2.6 percentage points, p > 0.10) or reservation wages (-3.5%, p > 0.10).RCTEffective Wage Differential Bundle MechanismThe logit intercept divided by the slope directly identifies the marginal value of time, proving that effective wage variation cleanly isolates willingness to supply incremental work hours without income effects.RCTEmployability-Driven Effect HeterogeneityFor job seekers with low employability (predicted median duration exceeding 6 months), assignment to an early integration agreement (month 1 or 3) increased the 1-year re-employment probability from 45% (month 6 reference group D) to 53% (group A) and 54% (group C) (p < 0.01), representing an 8 percentage point or 18% relative increase; for high-employability job seekers, early integration agreements had no statistically significant effect (82% vs 82–83%).RCTEmployed vs. Unemployed MVT DivergenceThe overall sample (including employed workers) yields a higher implied flow value of time ($\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.RCTEmployer 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 StudyEmployer 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.RCTExternal Employer Prescreening ServicesProviding prescreening hiring services directly to firms reduced employer evaluation costs and accelerated vacancy fill rates across participating businesses.RCTEmployer-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.RCTEmployment 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.RCTEndogenous 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).RCTEndogenous 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%.RCTEndogenous 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%**.RCTEndogenous 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 StudyEnglish 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.RCTBusiness 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 StudyEquilibrium 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$), demonstrating that equilibrium spillover losses offset roughly 27%–32% of firm-level hiring gains.Expert TheoryEquilibrium Search Modeling via Indirect InferenceA full rollout ($\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 TheoryEthnic 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 StudyEx-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.RCTExperience-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 StudyExport 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 StudyExtensive 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).RCTParticipation 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).RCTExtraversion 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.RCTFeasibility-Constrained Programme AggregationProgram aggregation eliminated demographic choice-set restrictions (such as native language requirements), increased sample sizes per category to maintain statistical estimation power, and aligned algorithmic choices with operational local course availability.Observational StudyFemale Labor Force UnderrepresentationFemale labor force participation in India was 27 percent in 2018 (roughly half the global average) and continues to decline, with migration spells remaining shorter and less frequent compared to males.Observational StudyGendered Labor Migration Social CostsFemale labor force participation in India stood at 27 percent in 2018 (half the global average); baseline loneliness among young migrant workers equals levels found in older adults aged 32–47 and chronically ill individuals.Observational StudyDeliberate Female Supervisory PromotionDeliberately promoting women to line supervisor roles successfully challenged and reduced discriminatory gender beliefs among factory staff while maintaining full operational line productivity with zero performance loss.RCTFinancial Relief vs Incentive DichotomyIncreasing payment per plate from INR 2 to INR 4 modestly increased production speed by 0.036 plates per hour but had zero effect on worker attentiveness. Conversely, early cash relief increased both production speed (+0.27 plates/hour) and high attentiveness (+7.7 percentage points) by reducing financial anxiety.RCTEarned Wage Access and Financial Stress AlleviationPaying wages in advance effectively mitigated worker stress associated with financial insecurity, generating direct productivity gains by restoring worker cognitive availability on the shop floor.RCTFirm Commitment Failure in General Skill ProvisionCombining external classroom instruction (180 hours/year) with monitored apprenticeship contracts led to a 48.4 percentage point increase in training participation (p < 0.0001) and a 10.83 month increase in training duration over the control group mean of 2.93 months.RCTFirm-Directed Active Labor Market PolicyTreated firms exhibited a 24% increase in permanent contract vacancy postings (0.047 additional vacancies over a 0.199 control mean, p < 0.01) and a 10.2% increase in permanent contract hires of registered jobseekers (0.046 additional hires over 0.450 control mean, p < 0.05), generating 17.5 additional theoretical workdays per firm (p < 0.05).RCTFirm Net Return on On-the-Job Soft Skills TrainingTreated workers became 20 percent more productive (10.8 percentage point efficiency gain, p < 0.05) after program completion, while wages increased by only 0.5 percent ($0.50 USD/month). Program costs were $95,000 for 1,087 treated workers, producing a net return to the firm of 73 percent at program completion and 258 percent 8 months post-completion.RCTSignal Variance Reduction for Risk-Averse FirmsTheoretical derivation proves that reducing signal noise variance ($\sigma^2$) strictly increases expected match value and wages for any employer risk-aversion coefficient $r < 1.2533$.Expert TheoryFirm-Scale Heterogeneity in Digital Platform AdoptionLarge firms (more than ten employees) increased candidate engagement under both advertising alone and joint treatments. In contrast, small firms (less than ten employees) increased engagement exclusively when assigned to the joint combination group.RCTFirm-Side Reservation Quality DowngradingAmong firms with high professional recruitment needs, market exposure significantly reduced the proportion of professional hires holding university degrees by 7 percentage points (p < 0.10) and reduced expected 12-month future hiring targets by 30% (from 45.6 to 32.3 workers, p < 0.10), aligning recruitment criteria with candidate availability.RCTFirm-Side Substitution BoundFor every 1.398 formal apprentices placed per firm, host firms displaced 0.318 traditional apprentices, yielding an estimated firm substitution parameter $\psi = 0.227$ (p = 0.128) and bounding net position creation between 74.1% and 77.3% of formal placements.RCTFirm-Specific Training Non-TransferabilityTraining was strictly firm- and project-specific (questionnaire terminology for a single health survey), and scores were never disclosed to outside employers. Yet participants achieved an 80% daily wage increase ($3.83/day), ruling out general human capital or skill signaling as the primary driver.RCTFirm Stipend Internalization and Fee RemovalHost enterprise owners eliminated entry fees (-5,303 FCFA, p < 0.0001) and reduced direct transport and meal payments (-3,698 FCFA, p = 0.004) to formal apprentices, lowering their total wage bill per formal apprentice by 4,054 FCFA per month (p = 0.021) compared to traditional apprentices in control firms.RCTFixed-Fee Referral InelasticityIncreasing fixed referral fees from Rs. 60 to Rs. 80 or Rs. 110 produced zero statistically significant impact on referral quality, choice of candidate, or task performance.RCTFixed-Fee Referral InvarianceIncreasing fixed finder's fees from Rs 60 to Rs 110 increased referral participation by 8 percentage points (p < 0.10) but had zero statistically significant impact on referral cognitive test scores (p = 0.865) or referral relationship composition.RCTFlat Participation Fees and Income TargetingElasticity of effort with respect to piece rates remains positive (+0.06), demonstrating that guaranteed show-up pay does not eliminate piece-rate incentive responsiveness or induce target-earning labor supply contraction.RCTFlexibility Productivity PenaltyParticipants who upgraded from office to flexible home work produced 19 percent less output per minute and experienced work sessions that were on average 10 minutes shorter due to home interruptions.RCTFlexible Formal Work Schedule ArrangementsWomen were willing to forgo higher wages in exchange for job schedule flexibility, and providing remote/flexible formal work arrangements led to significant increases in female labor force participation.RCTForced Random Search Decreasing ReturnsListing a vacancy first increased application probability by 0.440 percentage points (p < 0.001), but marginal applications yielded an interview rate of only 2.44% (p = 0.231 relative to 0%, p = 0.077 compared to 6.29% control return), demonstrating sharply decreasing returns compared to initiation-based search (5.87%).RCTForeign Experience DiscountResumes with foreign qualifications and foreign experience received a 6.0% callback rate compared to 15.7% for native Canadian resumes. Adding one domestic Canadian job increased callback rates from 6.0% to 8.5%, while replacing all foreign experience with Canadian experience raised callback rates to 11.0% (p < 0.01).RCTFormal Resume Experience Reporting DiscrepancySelf-reported survey data indicated that 15% of candidates had no prior work experience, whereas submitted résumé data indicated that 35% of candidates had no prior work experience, revealing a 20 percentage point underreporting gap on formal application documents.Observational StudyFrictionless Firm and Occupational Retention StabilityWealth shocks produce no statistically significant effect on employer switching, workplace changes, occupation transitions, industry moves, or geographic relocation across 10 post-win years, proving that intensive-margin labor supply adjustments occur almost entirely within existing employment arrangements.RCTGale-Shapley Algorithmic Match RecommendationAlgorithmic match recommendations increased the probability of actual worker-firm meetings by ~200% compared to non-recommended pairs ($p < 0.01$), whereas randomly suggested match recommendations showed no statistically significant effect ($p > 0.10$).RCTGanyu Informal Casual Labor Market Structure45% of surveyed ganyu contracts are piece-rate based while 55% are time-rate. Quality monitoring is present in 74% of contracts overall (62.5% for piece-rate vs 82.8% for time-rate), with severe penalties including unpaid redo of work or loss of daily wages.Observational StudyOn-the-Job Soft Skills Training for Line WorkersTrained workers demonstrated higher teamwork skills, a 4.7 percentage point (3.5%) increase in promotion probability, and a 16 percentage point (63%) increase in requests for further skill training. Production output rose by 7.4 percentage points (13.5%), yielding a net return on investment of 256% for the firm eight months post-training.RCTDecoupling of Entry Wages from Aggregate Economic GrowthAverage nominal wages in the control group grew strictly at the rate of inflation during a period when the national economy expanded at 8% per year in real terms.Observational StudyGender-Differentiated Employment GainsIn the Democratic Republic of the Congo, overall public works program increases in participant employment probability and average hours worked were driven primarily by female employment gains.RCTGender-Differentiated Selection and Outside OptionsWomen accept lower reservation rates (WTA is 2.3 to 3.0 MWK lower for women, p < 0.01), sort 0.76 more units per day, and make 0.16 fewer errors than men. The negative selection effect is driven exclusively by men, where a 10 MWK higher minimum WTA is associated with sorting 0.20 to 0.50 fewer units per day (p < 0.05); women display no significant selection relationship.RCTGender-Invariant Labor Supply Response to Unearned IncomeThe gender interaction term coefficient with yearly prize is +0.002 (standard error 0.057), demonstrating no statistically significant difference in marginal propensity to earn between men (baseline MPE of -0.124) and women (MPE of -0.122).Observational StudyGender-Sensitive Workplace Harassment MitigationBaseline and endline worker surveys tracking self-reported harassment, job satisfaction, attendance, and turnover; evaluation ongoing with results forthcoming.RCTGender-Targeted Workplace Safety and Harassment MonitoringImplementing safer harassment reporting surveys empowered female workers to report physical harassment by 290% (from a baseline of 1.5%) and sexual harassment by 271% (from a baseline of 1.8%).RCTGendered Household Influence and Caregiving BarriersWomen-led enterprises formalized at significantly lower rates than male-led firms following formalization incentive programs due to domestic care burdens, heavy family financial demands, and higher business closure rates.RCTGeneral Equilibrium Wage SpilloversIn India's NREGA, 80 percent of the total earnings increase for participants resulted from higher private sector wages rather than direct program transfers. In Ethiopia, public works rollouts increased private sector wages by 9 to 18 percent by reducing private sector labor supply.RCTHeterogeneous Impact DisparityThe upper quartile of participants who benefited most from the program saw short-term earnings increase by 2.2 times the earnings gain experienced by participants in the lowest quartile.RCTHigh-Frequency Managerial ObservationManagers in the study conducted an average of 4.7 classroom observations per year (nearly double the US principal average of 2.5) and dedicated 17.5 hours per week (37% of total work time) to direct teacher management and observation.Observational StudyHost-Refugee Labor Market Friction AsymmetryCash transfers increased Syrian wage employment by 5.2 percentage points at 2 months (p = 0.017) and 3.8 percentage points at 4 months (p = 0.027), while raising earnings by 65%. 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.RCTHousewife-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.RCTImmune 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.RCTIn-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.RCTIncome 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.RCTCapital 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).RCTInformal 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.RCTInformal 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.RCTInformal 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 StudyInformational 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).RCTFinancial 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 StudyIntensive 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).RCTIntensive 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%.RCTInter-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.RCTIntermediary 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).RCTIntermediate 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.RCTInternational 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).RCTInternational 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).RCTIntersectoral 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.RCTIntra-Production Line Soft Skill Productivity SpilloversUntrained workers on treatment lines accrued 8.02 additional person days during treatment (p < 0.05) and experienced efficiency gains of 7.14 percentage points post-treatment (over two-thirds the size of direct treatment effects), leading to an overall line-level efficiency increase of 4.31 percentage points (p < 0.05).RCTIntra-Week Task Familiarity and Learning DynamicsDaily output increases from 6.02 units on Day 1 to 8.12 units on Day 4 (+2.10 units sorted per day, p < 0.01), while error rates drop from 2.20 to 1.69 errors per unit (-0.51 errors, p < 0.01), robust to worker fixed effects.RCTJob Match Quality and Recurrence MitigationIntensive counseling significantly reduced overall unemployment duration while simultaneously extending employment tenure before unemployment recurrence.Observational StudyJob 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.RCTJob 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.RCTJob 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 StudyJobseeker 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).RCTJoint 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.RCTThe 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 StudyLabeled 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).RCTLabor 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).RCTLabor 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.RCTLabor 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.RCTEducational 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 StudyLabor 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.RCTLabor 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 StudyFormal 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.RCTLandless Labor Supply Income EffectIn villages experiencing delayed monsoon payouts, receiving an insurance payout lowered labor force participation by 28.5 percentage points (t-stat = -1.635) and reduced harvest labor supply by 15.44 days (t-stat = -1.391) at median rainfall deficiency.RCTLeisure Cost Disutility in Mandatory Activation ProgramsMandatory activation reduces job application costs from $\gamma_0 = 0.202$ to $\gamma_1 = 0.114$, but completely eliminates non-market time value $h = 0.013$ per month (equivalent to 1.3% of monthly productivity or ~2% of unemployment benefits).Expert TheoryLeisure Tax Hypothesis of Active PoliciesMandatory active labor market policy regimes act as a direct time tax, shortening average unemployment duration by 2.2 weeks (~15%) and generating a net social value of €2,000 per treated individual without requiring positive post-program skill gains.Expert TheoryLifecourse Career Aspiration and Workforce Attachment ShiftDesires to work for pay increased by 13 percentage points pre-marriage (p < 0.05; control mean 30%), 10 percentage points post-marriage before children (p < 0.05; control mean 19%), and 11 percentage points after children leave school (p < 0.05; control mean 23%).RCTLifecycle Labor Supply Anticipation EffectApplicants awaiting a voucher offer increased employment by 0.6 percentage points (approximately 1 percent relative to the control mean) during the pre-offer waiting period prior to receiving voucher assistance.RCTLiquidity Constraints in Optimal Job SearchMedian baseline search expenditure consumed 16% of total weekly expenditures (rising to 25% for 6-day searchers); receiving transport cash subsidies induced a temporary drop in low-quality work probability as cash-constrained youth substituted short-term casual work for active central job search.RCTLMIC Managerial Practice Adoption FrictionIndian garment sector employs over 45 million people facing high turnover; study measures whether scalable digital tools overcome adoption barriers to improve firm productivity and worker satisfaction.Observational StudyHigh Workforce Turnover in LMIC ManufacturingLow-tech manufacturing factories in low- and middle-income countries face turnover rates exceeding 75 percent annually.Observational StudyLocal Unemployment Rate Moderation of CCT RelianceIn areas with high youth unemployment (>25%), cash transfers increased counselor meetings by 6.58 (p < 0.01) versus 4.16 in low-unemployment areas (p < 0.01; equality test p < 0.01). Total personal monthly income increased significantly by €57.23 (p < 0.01) in high-unemployment regions, compared to a non-significant €19.05 increase in low-unemployment regions.RCTSpatial Locational vs Temporal Hour Flexibility DecompositionWorking from home with childcare multitasking increased labor take-up by 33 percentage points (228%) compared to 14.6% for office work, with effects driven primarily by working from home rather than flexible scheduling.RCTLong-Term Job Retention Matching in Counseling ProgramsPublic intensive counseling increased the probability of finding a job lasting at least six months by 34% (a 7.2 percentage point increase over the counterfactual). Private intensive counseling increased lasting job placement by 27% (a 5.0 percentage point increase).RCTLow-Ability Foot-in-the-Door EffectCandidates at the 25th percentile of baseline ability gained a 25 percentage point increase in post-intervention employment probability and earned $11.01 more per day. In contrast, candidates at the 75th percentile experienced a 1.5 percentage point decrease in employment probability and earned only $2.20 more per day.RCTLow Intertemporal and Hicksian Labor Supply ElasticitiesThe calibrated model yields an uncompensated (Marshallian) labor supply elasticity of 0.010, a compensated (Hicksian) elasticity of 0.096, and an intertemporal (Frisch) elasticity of 0.150; lifetime marginal propensity to earn ranges from -0.169 at age 20 to -0.036 at age 60.RCTLow-Productivity Cost OffsetsVacancies created by treated firms showed no difference in offered wages (log wage diff = -0.017, p > 0.10) or required experience, but were 12.1 percentage points more likely to be low-skilled/unqualified positions (p < 0.01), confirming that vacancy cost reductions selectively unlock lower-productivity job creation.RCTMacroeconomic Mitigation of Work DisincentivesA 1 percentage point increase in the unemployment rate surrounding the time of the voucher offer mitigated the ITT employment reduction by 0.006 (relative to an average ITT employment effect of -0.017), indicating weaker economic conditions at offer buffer against labor supply drops.RCTMacroeconomic Skill Mismatch and ShortageOnly 2.3 percent of India's workforce has formal skills training, while 56 percent of employers report difficulties filling job vacancies.Observational StudyMale Labor Supply CompensationMen in the full treatment group were significantly more likely to work in the public sector, compensating for household income that had shifted under the direct control of female household members.RCTManagerial Soft Skills TrainingManager soft skills training increased team productivity by 5.8% and manager wages by 6.0%. Six months post-training, the financial productivity gains were estimated to be 54 times the program implementation cost.RCTMarginal Applicant Phone Screening ProtocolRecruiters cite spoken language uncertainty as the primary reason for foreign resume rejections, yet systematically decline to perform 2-minute screening phone calls to verify language ability, resulting in severe misallocation of skilled labor.Expert TheoryMarginal Propensity to Earn Out of WealthWinning a lottery prize reduces annual pre-tax earnings by approximately 1.066% of the prize amount per year (p < 0.001); a 1 million SEK windfall reduces pre-tax earnings by 10,660 SEK per year (5.5% of sample average) and after-tax earnings by 0.576% per year; calibrated dynamic models yield a lifetime marginal propensity to earn (MPE) ranging from -0.17 at age 20 to -0.04 at age 60.RCTMarginal Value of Non-Work Time (MVT)Mean hourly MVT rises monotonically from $4.80 for 5–10 hours/week to $8.95 for 20–25 hours/week, $12.00–$14.68 for 30–40 hours/week, and $21.89–$22.69 for 40–50 hours/week, yielding an average flow value of non-work time relative to pre-tax predicted market wage ($\tilde{z}$) of 0.58 ($s.e. = 0.04$).RCTMatch Quality Optimization via Noise ReductionWorkshop skill certification increased the longest completed employment tenure by 1.2 months (a 10% increase over the 11.85-month control mean, p < 0.10), increased skill utilization in current jobs by 8.2 percentage points (p < 0.05), and raised earnings conditional on employment by 370.4 ETB (a 15% increase, p < 0.05).RCTMicro-Market Priority Targeting AlgorithmPrioritizing small and medium-sized firms (5 to 250 employees) in low-tightness micro-markets concentrated treatment among high-need sectors, achieving a 24% increase in permanent vacancies (p < 0.01) while keeping the proportion of treated firms in any single micro-market below 2% median.RCTCommute-Zone Micro-Market Tightness GranularityThe distribution of granular micro-market tightness yielded a median value of 0.35 across experimental firm locations, matching national macroeconomic slackness while enabling fine-grained subgroup treatment evaluations.Observational StudyMicro-Task Smartphone Crowdsourcing Compensation ModelParticipants earned approximately INR 1 ($0.013 USD in 2021) per verified task, earning up to INR 4,000 ($52 USD) across the intervention duration.RCTRural-to-Urban Migrant Female Labor VulnerabilityBaseline data context reveals severe retention, attendance, and well-being challenges among rural female migrants; impact evaluation tracking intervention effects ongoing.Observational StudyMixed Proportional Hazard (MPH) ModelThe MPH framework isolated a 20% to 40% time-varying increase in unemployment escape rates attributable to the policy regime, preventing bias from a small sub-population (1-2%) of unobserved 'immune' individuals with zero exit probability.Expert TheoryMobile SMS Vacancy DisseminationDelivering job vacancy information via SMS generated modest positive impacts on short-term (2-month) employment, whereas traditional non-digital intermediation produced no statistically detectable effect. Sending SMS alerts containing vacancies from both inside and outside the PES database yielded the largest gains in employability and online search activity at minimal additional cost.RCTMonopsonistic Employer Profit MaximizationEmployers maximize profit by offering the lowest piece rate (5 MWK) combined with quality monitoring, exploiting low worker bargaining power. For male workers, monitoring at low piece rates increases employer profit by nearly 50% compared to unmonitored contracts.RCTMorale-Driven Productivity Loss versus Lobbying DivergenceDisclosing higher pay progression under non-meritocracy produced no statistically significant change in worker communication with facility in-charges (-3.8 percentage points; p = 0.954) or non-patient task time share (p = 0.391), rejecting influence activities in favor of morale-driven output reductions.RCTMulti-Component Training BundlingStandalone skills training yielded no significant long-term impact on skills or employment; however, participants receiving hard-skills training bundled with an incentivized savings scheme experienced the largest positive impacts on job likelihood and total savings.RCTMulti-Contextual Network Spillover MismatchOver 35% of reported gifts and high-value loans (at least Rs 500) occurred between relatives compared to only 2% between coworkers, driving referrers to select low-skilled relatives unless external employer incentives outweigh social transfers.RCTMulti-Tiered Corporate Mentorship Apprenticeship ModelThe program significantly enhanced participants' core and transversal skills (including self-confidence, communication, digital literacy, and problem-solving), though it produced no statistically significant short-term increases in employment rates, days worked, self-esteem, or post-program educational re-enrollment.RCTMulti-Dimensional Skill Portfolio Signaling44% of participants scored in the top performance band for at least one skill, while only 10% scored in the lower half across all skills; as a result, earnings for the certified group strictly stochastically dominated control earnings.RCTMultinational Firm Transferability DeficitResumes listing foreign job experience at multinational firms received a callback rate of 6.8%, compared to 7.1% for resumes listing local foreign company names, showing no statistically significant benefit from brand recognition (p > 0.10).RCTNet Value of Apprentice WorkHost enterprise net value of work performed by apprentices increased by 21,380 FCFA per month (p = 0.0003), more than doubling the control group mean of 19,230 FCFA per month, while firm wage bills did not significantly rise (+4,391 FCFA, p = 0.177).RCTNetwork Incentive Trade-Off Threshold ConditionUnder the mathematical threshold where performance pay exceeds the social transfer differential divided by signal precision, high-stakes performance pay (50 Rupees) successfully incentivized participants to overcome network social transfer differentials, shifting referrals away from relatives by 7 percentage points and toward higher-skilled coworkers by 8 percentage points.RCTNetwork Inequality PerpetuationInformal networks account for 30–60% of jobs in the US and 45% of jobs in the Kolkata labor sample, creating substantial long-run inequality risks across socio-demographic groups if uncountered by meritocratic screening.Expert TheoryRandomized Saturation Design for Network SpilloversModerate transport subsidy saturation (40%) generated positive indirect spillovers on untreated neighbors, raising formal employment by 6.2 percentage points (p < 0.10) and permanent employment by 6.4 percentage points (p < 0.05); high saturation (90%) produced negative spillovers on permanent work (-6.8 percentage points, p < 0.01).RCTNon-Linear Compensated Labor Supply ElasticityCompensated labor supply elasticity is highly elastic below 30 weekly work hours (exceeding 1.0), but becomes highly inelastic at 40 hours per week and above (dropping to 0.5–0.6).RCTCross-Sectoral Wage Spillovers Outside Specialty RolesWhile employment increases occurred across both RA and non-RA roles, the overall post-intervention daily wage gains were primarily driven by employment in non-RA positions rather than continued research assistant work.RCTNon-RA Sectoral Wage SpilloverPost-intervention daily wage returns were driven primarily by non-RA positions (IV coefficient = $3.803, p < 0.10 for non-RA wages vs. $3.288 for RA wages; inverse hyperbolic sine log daily wage coefficient = 0.541, p < 0.10 for non-RA vs. 0.044 for RA), demonstrating that wage gains spilled over into general market positions rather than remaining confined to research roles.RCTNon-Skill Labor Market BarriersEmpirical results are forthcoming as the evaluation is ongoing, while baseline survey data highlights that 56% of Indian employers face hiring difficulties and 2.3% of the workforce holds formal skilling.Expert TheoryNon-Visible Ethnic Surname PenaltyResumes with Greek names experienced a statistically significant 4.0 percentage point reduction in interview callbacks (11.8% callback rate vs. 15.8% for English-named resumes), generating a penalty virtually identical to the 4.4 percentage point penalty experienced by Chinese, Indian, and Pakistani applicants.Observational StudyNon-Cognitive Soft Skills AssessmentTrainees who received objective feedback about their soft skills updated their expectations in line with reality regarding eligible jobs, though they became less willing to accept lower-quality employment.RCTNonlinear Income Effect Across Prize MagnitudesLinear specification yields an underestimated MPE of -0.051 due to extreme prize skewness, whereas a quadratic specification yields MPE derivatives of -0.114 at prize = $0 and -0.097 at median prize ($32,000), with a highly significant quadratic term (t-statistic = 4.8).Observational StudyExcludability of Biological and Physiological ChannelsCash infusion caused zero change in breakfast consumption (98% baseline rate) or sleep quality (p=0.671), and productivity gains persisted through the final 2 hours of the shift (+0.104 SDs, p=0.001), rejecting biological/nutritional mechanisms.RCTObservability Gradient in Labor Market BeliefsJobseekers' stated wage distributions closely matched prevailing firm salary data across occupational tiers, whereas jobseeker expectations of permanent employment (55% expected permanent job within 1 year vs 5.8% actual) and firm estimates of tertiary applicant cognitive test scores (overestimating tertiary ability premium by more than 4 times) exhibited massive structural biases.Observational StudyOccupational Language InvarianceThe callback ratio between English-named and foreign-named resumes remained virtually constant at 1.3 to 1.9 across all occupational deciles, showing a 3.4 percentage point callback penalty in low language-requirement jobs like computer programmer/maintenance technician (decile 1, callback ratio 1.4) compared to a 6.7 percentage point penalty in high requirement jobs like executive recruiter/community counselor (decile 10, callback ratio 1.7).RCTOccupational Relationship Referral SubstitutionHigh-stakes performance pay caused a 7.9 percentage point increase in referring coworkers (p < 0.05, from a 13.0% baseline) and a 6.9 to 7.2 percentage point decrease in referring relatives (p < 0.10, from a 14.8% baseline).RCTOff-Platform Search Non-DisplacementPhone call treatment changed off-platform search probability by -0.78 percentage points (p = 0.632) and monthly off-platform applications by -0.188 (p = 0.201). Off-platform employment probability changed by +0.18 percentage points (p = 0.910 unadjusted; +1.08 percentage points, p = 0.589 adjusted).RCTOrthogonal 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.RCTProgram 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.RCTPart-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.RCTPartially 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).RCTPay-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.RCTPay 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 StudyInsignificance 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).RCTPeer 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).RCTPeer 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.RCTPerformance-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.RCTHigh-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.RCTPersonalized 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.RCTPiece-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).RCTPlan-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).RCTPoint 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 StudyPortable 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.RCTPost-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.RCTPost-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 TheoryPost-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.RCTThe 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 ~$1,000, but exhibited zero statistically significant impact on post-program employment, earnings, grade point average, or college enrollment.RCTPost-Program Self-Employment TransitionPublic works program participants worked 16 percent more days in self-employment compared to non-participants, measured more than a year after program completion.RCTPost-Programme Negative ImpactEmpirical estimations revealed non-positive or negative exit hazard coefficients following program completion across multiple program types (e.g. vocational training post-completion coefficient -0.49 for control group members in Storstrøm).RCTPost-Training Livelihood AssistanceEmpirical findings are forthcoming as the evaluation is ongoing, with follow-up surveys planned via phone 3 months post-intervention.RCTPotential Experience Measurement BiasNonexperimental wage returns relying on potential experience proxies require approximately 10 years of estimated potential experience in Malawi to match the wage gain produced by 5 days of actual measured work experience, demonstrating that potential experience drastically underestimates true per-day returns while overstating accumulated work history.Observational StudyPre-Experimental Out-of-Sample Predictive ProfilingThe historical model successfully stratified the experimental sample into 1,688 high-employability ($\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.RCTPrecarious 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.RCTPrerequisite 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.RCTReinforced 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).RCTTime-Inconsistent Search Preferences12% of job-seekers exhibited incentivized present bias at baseline. Workshop treatment effects on permanent employment were significantly higher for present-biased individuals who failed to anticipate their time-inconsistency (p < 0.05).RCTPresent Bias and Non-Anticipated Revision in Search BehaviorUnanticipated present bias significantly moderates policy impacts; naive present-biased individuals who do not anticipate their revision behavior gain a **6.8 percentage point increase in permanent employment** from the application workshop (p < 0.01), whereas non-present-biased individuals exhibit no significant impact.RCTPrice Penalty and Financial Incentive Asymmetry in Program Take-UpApplication rates decreased significantly when charging a price fee, but showed no statistically significant increase when offering a positive cash incentive relative to free enrollment.RCTPrior Research Experience Return MagnificationAcquiring short-term work experience yielded a statistically significant positive wage interaction for candidates with prior research experience (interaction coefficient = 1.079, standard error = 0.618, p = 0.06), demonstrating magnified wage gains for research-experienced individuals.RCTPrivate Contractor Job Placement CounselingAssigned personal advisors to maximum 40 clients for weekly meetings over six months, costing between €900 and €3,947 per client depending on placement. Increased job placement probability by 22% within six months (a 4.5 percentage point increase). Increased likelihood of finding a job lasting at least six months by 27% (a 5 percentage point increase). Increased total net expenses per enrolled job seeker by approximately €1,162 without reducing days of unemployment benefits paid.RCTPrivate Sector Wage SubsidiesPrivate sector wage subsidies were utilized for 8%–12% of treatment group members (vs 4%–6% control) and yielded positive post-program exit effects in Storstrøm (completion coefficient 0.97) compared to public sector temporary jobs.RCTPrivate Vacancy Access ControlTreatment increased the proportion of vacancies made private (restricted from public online access) by 57% off the control mean, directly reducing unvetted jobseeker applications.RCTPrivate Vacancy FilteringTreatment increased the proportion of vacancies designated as private (hidden from public internet access) by 57% (0.030 increase over 0.053 control mean, p < 0.01), which mechanically reduced direct jobseeker applications by 39% (-2.67 applications, p < 0.01).RCTPrivate Vocational Training Investment Response to Market DemandWomen aged 18–24 in treatment villages were 2.8 percentage points more likely to enroll in vocational training (p < 0.01) relative to a control mean of 0.5%, whereas men showed no significant change (0.3 percentage points, p > 0.10).RCTPrivate vs. Group Mentoring ModalitiesEmpirical comparisons of employment rates and income outcomes between private and group modalities are forthcoming as the study evaluation is ongoing.RCTProactive Firm Prospection CampaignActive prospection generated a 488% increase in agency counselor visits to treatment firms (jump of 0.5 visits per firm) and a 152% increase in phone contacts (1.5 additional calls per firm) during the intensive phase.RCTProbabilistic Job Offer InstrumentThe probabilistic job offer assignment strongly predicts short-term employment acquisition with a first-stage F-statistic of 76.36. Assigning 50%, 75%, or 100% probabilities increases job acquisition by 40.2, 56.8, and 83.7 percentage points respectively (p < 0.01).RCTProbationary Trial Period ScreeningCombining PES pre-screening with statutory trial periods resulted in a 14% increase in hires who remained off unemployment registers for at least 12 months (0.046 quality hires, p < 0.01), showing that 100% of the net permanent contract hiring increase successfully survived probation.RCTProductivity Signaling and Unemployment Stigma MitigationThe intervention increased permanent contract hires of registered jobseekers by 14% (+0.046 hires per firm, p < 0.05) and stable quality hires lasting at least 12 months by 14% (+0.046 hires, p < 0.01), while producing no significant hiring increase for non-registered jobseekers.RCTActive Program Lock-In EffectSpecific active labor market programs exhibited zero positive direct impacts during participation, showing statistically significant negative lock-in effects on unemployment exit rates during program weeks and negative post-program effects across training, subsidized job, and education categories.RCTProgram Outcome Stigma versus Welfare StigmaEmphasizing that training was subsidized for financial hardship produced no statistically significant change in application rates (+0.003, SE = 0.022, control mean = 0.426) and generated no significant heterogeneous treatment effects across machine learning groups (p = 0.315).RCTProgramme Factory Rule-Based ActivationMandatory 80% time participation rules resulted in programmatic inefficiency, leading policy makers to loosen continuous activation mandates in 2003.Observational StudyProject QUEST Long-Term Support ModelAnnual earnings for participants were $5,080 higher (a 22% increase, p < 0.01) in Year 6 and remained $4,616 higher (a 15% increase, p < 0.01) in Year 11. 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.RCTService 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.RCTPseudo-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 TheoryPsychosocial 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.RCTIntegrated 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.RCTPublic 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.RCTPublic 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 StudyPublic 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%). Increased likelihood of finding a job lasting at least six months by 34% (a 7.2 percentage point increase). Reduced net costs to government per job seeker slightly, though the cost difference was not statistically significant.RCTPublic Skill CertificationJob seekers who received public branded certificates were 5.2 percentage points more likely to be employed, increased total hours worked by 20%, and earned US$130 over 3 months (generating an earnings gain 5.6 times greater than the per-participant program cost).RCTPublic Sector Benefit-Cost Return on InvestmentYearUp generated a total net benefit to society of $15,349 per participant ($38,484 in total benefits compared to $23,135 in total costs), returning $1.66 to society for every $1.00 spent on program operations (a 66% net positive return, p < 0.01).RCTPublic Work History & Reputation RatingsDisplaying detailed public information about workers' previous performance significantly increased job matches and overall earnings for strong performers on the platform.RCTPure Signaling Value of Grade DiscontinuitiesCrossing a certificate score band cutoff raised 4-year earnings by 0.332 standard deviations (p = 0.13 for optimal bandwidth, p < 0.10 for double bandwidth), confirming that official band labels directly drive wage premiums.RCTQuality Monitoring and Multitasking SubstitutionQuality monitoring decreases output quantity by 0.440 to 0.689 units per day (p < 0.01) while significantly improving quality by reducing sorting errors by 0.561 to 0.744 errors per unit (p < 0.01). Explicit quality monitoring does not increase worker reservation rates (WTA effect = -0.431 MWK, p > 0.10).RCTRacial Earnings Gap Structural MitigationFrom 2000 to 2019, Black workers' median wages were 75.6% of white workers' median wages; sectoral interventions generated earnings gains for workers of color driven by a 33 percentage point increase in IT sector placement (37% vs 4%, p < 0.01) in YearUp and an 8 percentage point increase in technical health roles (29.4% vs 21.5%, p < 0.01) in Project QUEST.Observational StudyRandomized Controlled Evaluation of Workforce ProgramsRandomized sorting ensured baseline equivalence between groups, establishing that sectoral programs causally increased 2-year earnings by $4,500 in SEIS (18% increase, p < 0.01), 5-year earnings by $2,716 in WorkAdvance (11.5% increase, p < 0.01), and 11-year earnings by $4,616 in Project QUEST (15% increase, p < 0.01).RCTRandomized Saturation Spillover DynamicsAverage indirect spillover effects on untreated neighbors were statistically zero across employment (-4.6 percentage points, p > 0.10) and earnings (-41.1 ETB, p > 0.10), proving that search interventions at this scale do not displace non-treated youth in integrated urban labor markets.RCTTemporal Persistence Disproving Gift-Exchange Motivations in Workplace TrainingProductivity treatment effects were small and statistically insignificant during the 12-month training phase (+3.0 percentage points, p > 0.10) but grew significantly post-completion (+10.8 percentage points, p < 0.05) and persisted for 8 months, disproving gift-exchange reciprocity and confirming genuine skill accumulation.RCTReference Letter Invalidation by NetworksAcquiring experimentally induced work experience reduced the probability of submitting a reference letter by 7.9 percentage points (p > 0.10) and decreased the frequency of reference letter submissions by 0.381 times, demonstrating that formal signaling via reference letters did not drive the observed wage gains.RCTReferral Quality Incentive Gap in Job NetworksUnder standard unincentivized conditions, male recommenders do not systematically refer the highest-quality candidates from their social networks; offering explicit financial performance incentives significantly increases the ability and test scores of referred job seekers.RCTRelational Trust Deficit in Entry-Level HiringOver two-thirds of surveyed firms cited employee recruitment challenges as a major growth barrier, and 53 percent specifically identified trust and worker behavioral concerns as their primary hiring hurdle.Observational StudyReputational Screening WorkshopsTested job seekers receiving hard-to-observe skill certificates were significantly more likely to receive a formal and permanent job offer while performing the same amount of job search as comparison candidates.RCTReservation Wage EscalationFive years post-program completion, public works participants experienced a 5 percentage point decline in the probability of engaging in any income-generating activity compared to non-participants, driven by elevated wage expectations and missed private sector opportunities.RCTReservation Wage Inelasticity to ExperienceShort-term work experience produced a statistically non-significant effect on monthly reservation wages (IV estimate = +$124.40, p > 0.10) and no significant increase in active job search duration (IV estimate = +0.089, p > 0.10), ruling out reservation wage shifts as the mechanism driving daily wage returns.RCTReservation Wage Rigidity Post-Employment ExposureReceiving short-term work experience resulted in a $124.40 increase in monthly reservation wages that was statistically insignificant (p > 0.10), and produced no statistically significant increase in the proportion of time spent actively searching for work (coefficient = 0.089, p > 0.10).RCTResume-Survey Experience Measurement DiscrepancyWhile only 15% of respondents reported no prior work experience in self-reported survey modules, 35% lacked work experience on their submitted résumés, revealing a 20 percentage point discrepancy caused by infrequent résumé updates and differing worker definitions of suitable CV entries.Observational StudyReward Devaluation Productivity SlumpCorrecting downward an overestimated supervisor salary under a meritocratic promotion regime reduced household health visits by 21% (-2.045 visits; p < 0.05), whereas under a non-meritocratic regime the effect was non-significant (-0.639 visits).RCTRoutine Task Intensity ReductionFour years after baseline, formal dual apprentices increased non-routine analytical task involvement by 0.243 standard deviations (p < 0.0001) and decreased overall routine task intensity by 0.213 standard deviations (p = 0.008).RCTRule-Based Cognitive Screening in Informal MarketsAbstract logic and pattern-matching tasks successfully stratified participant cognitive capacity in low-literacy informal labor settings without reliance on formal schooling credentials.RCTSanction Enforcement Asymmetry in Social Service OutsourcingPrivate providers applied sanctions (temporary or permanent removal from unemployment rolls for inactivity) significantly less frequently than public employment services, leading to reduced candidate job search effort.RCTPersonal Empowerment Workshops and Targeted Vocational Training ModelVocational training improved participant resilience, job search proactivity, organization, and overall job search behaviors, while empowerment workshops boosted job search motivation and proactivity; however, neither intervention increased short-term employment probability.RCTScale Invariance of Marginal Labor Supply EffectsEstimated marginal effects per unit of wealth are statistically indistinguishable across small, moderate, and large lottery prizes, rejecting hypotheses that fixed adjustment costs suppress labor supply responses to moderate wealth windfalls.RCTFormal Schooling Expansion as Formalization EngineIncreased average schooling levels served as the primary mechanism explaining the 12 percentage point drop in Brazilian labor informality from 2003 to 2012, counteracting the informalization pressure from rising minimum wages.Expert TheorySearch Acceleration versus Employability DecayTreated job seekers had a statistically significant 2.5 percentage point employment advantage over untreated peers at 8 months, but by 12 and 20 months, employment rates between treated and comparison groups were identical.RCTSearch Channel Substitution Under MonitoringIncreased monitoring yielded no significant overall increase in transition rates to employment, but induced a direct shift from informal to formal job search methods.RCTDecoupling Search Intensity from Employment OutcomesThe transport subsidy increased active job search by **12.5%** (5 percentage points, p < 0.05) and job board visits by **30%** (9 percentage points, p < 0.01) but generated **zero 4-year wage gains**; conversely, the application workshop caused **no change in search intensity** or application volume, yet increased 4-year monthly earnings by **20%** (299.5 ETB, p < 0.05).RCTSearch Intensity vs Search Efficiency DivergenceTransport subsidies increased search probability by 12.5% and vacancy board visits by 9 percentage points without altering long-term outcomes; the application workshop left search intensity unchanged but improved permanent offer conversion from 1 offer per 7.2 applications in the control group to 1 per 5.2 applications (p < 0.10).RCTSeasonal Labor Supply and Liquidity ConstraintsHigh-season workers facing acute liquidity constraints and lean food months report higher recent daily wages (344.6 MWK vs 257.7 MWK, p < 0.01) and sort 0.48 more units per day (p < 0.01). Self-reported cash-generating outside options significantly lower minimum reservation rates within worker.RCTSectoral Employment Impact Study (SEIS)Over two years, participants earned $4,500 more (an 18% increase, p < 0.01) than control group members, with Year 2 earnings $4,000 higher (a 29% increase, p < 0.01). Year 2 employment reached 70% compared to 60% for the control group (a 10 percentage point increase, p < 0.01). Participants were 14 percentage points more likely to work jobs paying at least $11/hour (59% vs. 45%, p < 0.01) and 10 percentage points more likely to secure jobs offering benefits (57% vs. 47%, p < 0.01).RCTSelf-Belief Updating and Directed Job SearchYoung job seekers in Johannesburg updated their beliefs about their abilities, redirected search efforts toward aligned sectors, and cumulatively earned 1.8 times more than program operating costs within 3.5 months.RCTSequential Labor Stepping-Stone DynamicsAssignment to flexible work increased job offer acceptance 10 weeks later by 6 percentage points, reduced maternal gender traditionalism by 0.05 standard deviations, reduced older children's gender traditionalism by 0.1 standard deviations, and increased paternal domestic help by 9 percentage points (a 16% relative increase over the 58% control mean).RCTSequential 'No Programme Now' Dynamic BaselineDefining Option 0 dynamically eliminated survivor selection bias in counterfactual estimation, showing that "no programme now" was the statistically optimal choice for 21–23% of jobseekers in Basel and Bern.Observational StudyService Sector Female Labor PreferenceWomen hold approximately 45 percent of all BPO jobs in India—substantially higher than in most other industries—with starting salaries ranging from 5,000 to 10,000 INR (US$110-220) per month, which was twice the average pay of non-BPO jobs for similar education levels.Observational StudySignal Variance Reduction ModelReducing signal variance ($\sigma^2$) strictly increases both the unconditional hiring probability $\Phi\left(\frac{-0.5r\sigma^2}{\sqrt{1+\sigma^2}}\right)$ and expected match quality, provided the firm's absolute risk aversion coefficient $r < 1.2533$.Expert TheorySkill Certification and Signaling WorkshopThe workshop increased 4-year earnings by 20% (USD 10 per month) above the control mean at a one-off cost of USD 18.20 per person. It increased short-run permanent employment by 6.9 percentage points (a nearly 60% increase over the 12% control mean) and increased job tenure duration by 10%.RCTSkill Signaling via Reference Letters and CertificatesStandardized reference letters significantly increased employment rates for female applicants in South Africa while having no effect on men, correcting employer baseline bias against women's reported skills. In the United States, reference letters increased employability and earnings sustained over a four-year follow-up period. Algorithmic writing assistance on resumes increased hiring probabilities by 8 percent in online labor markets.RCTSkill Signaling via Dual CertificationSubsidized dual apprentices achieved a 15.1 percentage point higher rate of formal skill certification (p < 0.0001) relative to a 9.5% control mean, contributing to a 15% increase in total earnings (9,394 FCFA/month, p = 0.0169) 2 years post-program completion.RCTSkill Signaling via Application WorkshopThe workshop increased the probability of **permanent employment by 60%** (6.9 percentage points over a 12% control mean, p < 0.01) after one year. Four years later, the intervention increased **monthly earnings by 20%** (299.5 ETB, p < 0.05) and **job satisfaction by 7 percentage points** (p < 0.10).RCTSobering Belief ShockMarket exposure reduced worker reservation wages by 6.6% (p < 0.10) and wage mismatch by 4.2% (p < 0.10), while increasing job board visits by 3.01 visits (p < 0.05); treated firms increased professional vacancy advertising by 12 percentage points (p < 0.01) and job board recruitment by 9.6 percentage points (p < 0.05).RCTSocial Benefit Formalization Disincentive (Welfare Trap)Monthly cash transfers restricted to non-formal workers created a statistically significant disincentive for program beneficiaries to accept formal employment contracts.Observational StudySocial Job Network ExpansionAcquiring short-term work experience increased the probability of receiving any job referral by 22.2 percentage points (p < 0.05) and increased the overall social network index by 0.306 standard deviations (p < 0.10) over the 8-month follow-up period.RCTSocial Network Expansion MechanismExperimentally induced short-term work experience increases the likelihood of hearing about a job opportunity through contacts met during the intervention by 22.2 percentage points (p < 0.05). It increases the standardized social network index by 0.306 standard deviations (p < 0.10).RCTInformal Social Network Search FrictionsBaseline survey results indicate that Yuva Parivartan graduates experience initial placement difficulties and disproportionately depend on personal social connections to find employment.Observational StudyEmpirical Prevalence of Occupational Stigma Misperceptions43% of jobseekers explicitly acknowledged that society looks down on entry-level jobs (10% reported "most of society", 33% reported "many people"), and approximately 25% reported that taking such jobs would negatively affect family and peer relationships.Observational StudyComplementarity of Soft Skills with Technical Skill AccumulationTrained workers were 15.8 percentage points more likely to request technical skill development training (p < 0.01; control mean = 24.9%), leading to assignment to more complex operations (SAM increased by 0.0384 minutes, p < 0.05), while efficiency gains were largest among machine operators with technical skills (+4.95 percentage points, p < 0.10).RCTSpatial Search Cost FrictionsTransport subsidies increased job search probability by 12.5% and central job board visits by 9 percentage points (nearly 30%) during the intervention. At 8 months, formal employment rose by 5.4 percentage points, but all impacts on employment and earnings completely dissipated by 4 years.RCTSpatial Distance Frictions in Centralized Job SearchLiving 10 km closer to the city center is associated with visiting central job boards 6.7 more times per year (0.4 SD) and submitting 1.9 more permanent job applications (0.5 SD), with active job-seekers spending a median of 16% (and up to 25%) of total weekly expenditure on search costs.Observational StudySpontaneous Candidature PromotionTreated firms received nearly 1 additional spontaneous candidate profile push per firm from public counselors compared to control firms which received virtually zero (a 488% jump in total counselor interactions including spontaneous profile pitches, p < 0.01), effectively uncovering latent job demand.RCTSpousal Labor Supply Underestimation GapIndividual married winners reduce pre-tax labor earnings by 0.965 SEK per 100 SEK won, while their spouses reduce earnings by 0.408 SEK per 100 SEK won; the total household response is -1.306 SEK per 100 SEK won, indicating that individual-level analysis understates true total labor supply reductions by 23%.RCTStandardized Cognitive Task BenchmarkingPerformance on the experimental cognitive quilt task correlated significantly with Raven's Progressive Matrices and Digit Span scores (p < 0.05), validating the puzzle metric as an accurate construct for measuring real cognitive skill.RCTStandardized Digitized Technical AssessmentResearch ongoing with results forthcoming; measuring impacts of digitized testing on promotion consistency, hiring rates, equity, and factory productivity.RCTStandardized Employer Reference LettersYouth receiving automated recommendation letters earned US$1,349 more cumulatively across four years and stayed in jobs 0.36 months longer. In South Africa, women using reference templates saw higher application review rates and increased 3-month employment rates, closing gender hiring gaps.RCTStatistical Stereotype Mitigation via Signal PrecisionModel proves reducing signal noise ($\sigma^2$) directly increases hiring probability for applicants with low observable proxies ($z_i$), contributing to a reduction in the high-to-low predicted earnings gap from 142% to 54%.Expert TheoryStatistical Targeting vs. Profiling SystemsEmpirical analysis demonstrated that long-term unemployment risk is not highly correlated with individual programme impacts, proving that targeting systems provide superior allocation efficiency over traditional profiling models.Observational StudyStatistically Assisted Programme Selection (SAPS)Providing econometric predictions to treatment caseworkers produced zero statistically significant change in programme assignment behaviour, with short-term compliance between recommended and assigned programmes remaining identical at 12% (Definition 1) and 29–30% (Definition 2) for both treatment and control groups.RCTBaseline Status Buffering in Stigma ResponseProfessional stigma treatment increased the share of rich applicants by 62% (p < 0.01) and currently working applicants by 28% relative to control. In Experiment 2, salient stigma treatment attendees were significantly older (+2.79 years, p = 0.02) and had higher baseline status scores on the Lasso index (+0.914 SD, p = 0.02).RCTStatutory Gender Quotas and Worksite SupportNationally, 40% of women who wanted work were employed versus 78% of men; MGNREGS policy guidelines legally mandate that at least one-third of beneficiaries be women alongside worksite childcare provisions.Observational StudyStatutory Benefit-Cutoff Sanction MechanismFailure to fulfill agreed search obligations or submit application verification results in a mandatory 2-week total unemployment benefit withdrawal ("Sperrzeit"), with repeated infractions triggering complete benefit disqualification for extended durations.Expert TheoryAbsence of Stepping-Stone Effect in Temporary EmploymentShort-term employment gains at eight months were driven entirely by job seekers finding fixed-term contracts with zero increase in permanent employment contracts, and all employment advantages vanished completely after twelve months.RCTStatistical Discrimination MitigationSignaling workshop gains were heavily concentrated among disadvantaged workers lacking tertiary education (40% wage increase over control) and those without prior permanent work experience. The intervention fully eliminated the 34% baseline earnings gap between experienced and inexperienced workers.RCTStigma Beliefs and Pecuniary Expectations DecouplingStigma salience information significantly increased the belief that society looks down on entry-level jobs (+0.10 points, p < 0.01) and decreased expected family pride (-0.15 points, p < 0.10), while producing zero statistically significant change in expected starting salary (+57 EGP/month, p = 0.27) or 5-year expected salary (-92 EGP/month, p = 0.46).RCTStigma Salience versus Mitigation Dual DynamicMerely mentioning social stigma reduced job fair attendance by 1.4 percentage points overall and by 12.0 percentage points for the bottom predicted response group (p = 0.022). Adding testimonials attenuated this negative effect to -0.044 percentage points (statistically insignificant), demonstrating that salience forces can offset mitigation efforts.RCTStigma Mitigation Policy Targeting Trade-OffStigma treatments shifted the applicant baseline characteristics index by +0.174 standard deviations in Exp 1 (p < 0.05) and +0.914 in Exp 2 (p < 0.05), increasing the applicant share of wealthy jobseekers by 62% (p < 0.01) and currently employed jobseekers by 28% (p < 0.05).RCTStratified Partial Likelihood for Externality IdentificationParticipation in the activation program reduced non-participants' unemployment exit hazard rate by approximately 5% ($\gamma = -0.048$, p < 0.10 in full covariate model; $\gamma = -0.079$, p < 0.05 in South Jutland sub-sample).Observational StudyStress Reduction via Probabilistic Fallback JobsTraining test performance strongly predicted hiring by the primary recruiter (R² = 0.357, where a 1 standard deviation increase in composite test score increased hiring probability by 9.7 percentage points). Receiving a higher guaranteed probabilistic outside job offer significantly increased candidate test performance during training by alleviating job-uncertainty stress.RCTSoft Skill Driven Promotion Expectations and Relative Performance ElevationTreated workers were 8.71 percentage points more likely to expect a career promotion within 6 months (p < 0.05; a 15% increase over control mean of 56.3%) and ranked their productivity significantly higher relative to technical skill grade peers on a 6-step ladder (p < 0.10).RCTSubjective Earnings and Employment Expectation UpdatingRecruitment services significantly increased the reported expected probability that a girl with a secondary education would obtain a well-paying service job, alongside a statistically significant increase in expected monthly earnings for educated young women.RCTSuboptimally Low Search EffortReducing initiation costs increased application volume 7-fold and interview volume 7-fold without reducing interview yields per application (p = 0.647) or creating crowd-out on control applicants (p = 0.589), demonstrating that baseline job search effort is suboptimally low due to initiation frictions.RCTSubsidized Dual ApprenticeshipFour years after baseline, assigned youth experienced a 15% increase in total earnings (p = 0.0169), spent 10.83 additional months in training (p < 0.0001), and achieved a 15.1 percentage point higher rate of skill certification compared to the control group mean of 9.5%.RCTSubsidized Employment Pathway AccelerationEarly integration agreements accelerated transitions into wage-subsidized roles and business startup grants (Gründungszuschuss lasting up to 15 months), driving early 180-day exit increases among low-employability job seekers before unsubsidized employment rates converged at 365 days (7.4 percentage point increase in unsubsidized jobs for Group A vs D).RCTSubsidized Vocational Job TrainingVocational job training programs significantly increased participants' probability of securing formal employment and improved overall employment quality compared to non-participants.RCTSupervisory Cost-Penalized Task MetricA perfect standardized score of 20 per puzzle required completion in under one minute with zero incorrect attempts; incorrect attempts and excessive completion times continuously lowered scores, with uncompleted puzzles receiving zero.RCTSupervisory-Time Efficiency MetricStandardized composite scores incorporating supervisory friction penalties differentiated referral performance and proved sensitive to referral incentives (mean = -0.009, SD = 1.00 across cognitive tasks).RCTSupply Chain Safety Compliance and OSH CommitteesEnforcing safety and health committees improved safety checklist performance by 0.23 standard deviations in Bangladeshi apparel suppliers, with improvements concentrated in well-managed firms with strong worker-manager communication.RCTTargeted High-Productivity Firm FormalizationThe average positive formalization effect of incentive programs in Brazil was driven 100% by high-income entrepreneurs, as small low-productivity firms derived negligible benefit from formalizing.RCTTask Complexity Reallocation via Standard Allowable MinutesSoft skills training significantly increased assigned task complexity, raising operation SAM by 0.0384 minutes post-treatment (p < 0.05; relative to a control baseline mean of 0.565 minutes), demonstrating that supervisors systematically assigned soft-skilled workers to more complex sewing operations.RCTTheoretical Workday StandardizationWorkday standardization filtered high-variance short-term contract noise (which had a standard deviation 9.9 times larger than permanent contracts), revealing a statistically significant increase of 17.5 theoretical workdays per firm for registered jobseekers (p < 0.05) and 43.8 workdays across all jobseekers in permanent contracts (p < 0.05).RCTThird-Party Credential Accreditation InefficacyAttaching formal third-party accreditation to foreign educational credentials produced virtually zero effect on callback rates (point estimates ranging from -0.014 to +0.007, statistically insignificant), failing to reduce the callback gap between foreign-educated and native-educated applicants.Observational StudyThree-Channel Search Effort DisaggregationControl vacancies received 3.588 caseworker matches, 1.102 firm-initiated candidate searches, and 6.862 organic jobseeker applications; treatment reduced firm search effort by 0.841 matches (p < 0.01) and organic jobseeker applications by 2.670 (p < 0.01).RCTTotal Opportunity Cost Parameter (z)Accounting for commuting costs (+0.06), foregone welfare benefits (+0.06), and childcare expenses elevates the baseline non-work value ($\tilde{z} = 0.58$) to a comprehensive total opportunity cost parameter of $z = 0.72$ under monopsony assumptions, or $z = 0.87$ under Diamond-Mortensen-Pissarides assumptions.RCTTournament Incentive Heterogeneity by Worker Rank and HorizonMeritocratic promotions boosted household visits by 38% (+2.348 visits; p < 0.01) for high-ranked workers versus +0.965 for low-ranked workers, and by 45% (+3.476 visits; p < 0.01) for workers expecting a supervisor retirement within 5 years versus +1.260 for distant horizons.RCTTransferable Industry-Recognized CredentialsSectoral programs substantially increased industry-recognized credential attainment; earnings gains were driven by placement in higher-paying credentialed jobs rather than total hours worked, yielding hourly wage increases of nearly $4/hour (a 31.7% increase, p < 0.01) in YearUp and a 14 percentage point increase in jobs paying over $11/hour (59% vs. 45%, p < 0.01) in SEIS.RCTTransitory Vacancy Posting DecayWhile permanent contract hiring gains remained persistent through the entire 16.5-month period, treatment effects on vacancy postings with the Public Employment Service peaked during the sanctuary period (+24%, p < 0.01) and progressively decayed starting May 2015 as proactive counselor contact ceased.RCTTransport Search Cost SubsidyTransit subsidies increased **active search likelihood by 12.5%** (5 percentage points, p < 0.05) and **job board visits by 30%** (9 percentage points) during intervention weeks, raising 1-year formal job rates by 5.4 percentage points (p < 0.01), but generating **no statistically significant long-term earning gains** after four years (30.9 ETB, p = 0.753).RCTSpatial Search Frictions and Transport SubsidiesIn Ethiopia, transport subsidies helped youth secure higher-quality employment and reduced job seeker discouragement. In South Africa, transit subsidies to access city centers adjusted wage expectations toward realistic market rates and increased acceptance of jobs closer to home. In Jordan, direct cash transfers significantly increased job search effort, employment rates, and total earnings among refugees.RCTTripartite Job Stigma TaxonomyProfessional stigma messages decreased application rates by 2.9 percentage points on average (-0.125 percentage points for the bottom Machine Learning group, p = 0.015), while personal stigma messages showed virtually zero effect (+0.006 average, +0.047 bottom group, p = 0.756), proving these stigma dimensions operate through distinct psychological mechanisms.RCTTwo-Step Cluster Randomization DesignWhile individuals offered counseling were 2.5 percentage points more likely to find long-term employment after eight months than untreated peers in the same communities, untreated peers in treated communities were 2.1 percentage points less likely to find jobs than job seekers in pure comparison communities where 0% were treated.RCTUncensored Aggregate Income TrackingWhile conditional wage comparisons suffered from duration-dependent sample censoring, total 365-day cumulative income tracked across all randomized participants provided a selection-free metric of total participant financial outcomes across treatment arms.RCTUnconditional Quantile Earnings GainThe cumulative distribution of total earnings for treated youth shifted uniformly rightward across all quantiles (Mann-Whitney permutation p = 0.0005), confirming medium-term earnings gains (+15%, p = 0.0169) were distributed across low, middle, and high earners rather than driven by outliers.RCTUncredentialed Job Fair IneffectivenessUncredentialed job fairs produced zero statistically significant long-term impacts on youth employment or earnings, functioning only to realign biased subjective beliefs regarding workforce market availability.RCTUnmonitored Quality Reciprocity (Gift Exchange)In the unmonitored condition, increasing piece rates has a negligible effect on error rates (+0.006 to +0.009 errors per unit, p > 0.05), indicating workers do not excessively compromise quality for speed when piece rates rise, consistent with gift-exchange reciprocity or anti-shirking norms.RCTSelective Responsiveness of Unmotivated Workers to SanctionsThe interaction between accountability treatments and baseline reciprocity was consistently negative (e.g., Monetary Penalty x Baseline Reciprocity coefficient = -0.269, p = 0.022), demonstrating that accountability sanctions selectively increase prosocial performance among unmotivated workers who have higher baseline absenteeism.RCTSocial Network Extraction of Unobservable ProductivityAdding controls for resume-observable variables and formal testing metrics did not reduce the productivity premium of referrals chosen by incentivized high-ability participants (coefficient remained 0.383 standard deviations versus 0.370 standard deviations in the baseline specification).RCTExternal Market Unobservability of General Soft SkillsDespite a 20 percent productivity increase (10.8 percentage point efficiency gain, p < 0.05), post-program long-run worker turnover showed zero differential retention or attrition (0.620 percentage points, p > 0.10) and wage increases remained negligible (0.492 percent, p < 0.10), proving that soft skills are unpriced by external labor markets due to unobservability.RCTUnsafe Search RegimeProves mathematically that in the intermediate "unsafe regime" where minimum qualification $z$ binds, a downward belief shock ($\mu$) increases search expenditure ($s$) to avoid remaining unmatched under vacancy penalty ($\kappa$).Expert TheoryUpfront Applicant Screening MechanismMandatory upfront screening ensures candidate readiness for technical training; programs utilizing strict screening achieved up to a 41 percentage point increase in targeted sector employment (61% vs. 20%, p < 0.01) and 19.6% long-term earnings increases (p < 0.01).Expert TheoryUpward Feedback and Worker Voice ChannelsSupervisor evaluation programs caused managers to become less critical, increasing team-level KPI performance by 2.3% in Chinese auto manufacturing. Open supervisory discussions increased productivity by 10.6% and retention by 10.3% after 12 weeks. In India, survey completion after unsatisfying wage hikes reduced quit likelihood by 20% (0.23 percentage points).RCTUrn-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 TheoryUrn-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 TheoryVacancy 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).RCTVacancy 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.RCTVertical 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.RCTVideo-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.RCTVillage 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.RCTOpportunity 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.RCTWage 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.RCTWelfare 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 TheoryWhite-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 ($110-220 USD) per month in 2003, representing 200 percent of the average pay for non-BPO workers with similar educational attainment.Observational StudyWindfall Effect on Youth Training Supply25.9% of formal apprentices substituted out of traditional informal apprenticeships ($\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.RCTWithin-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).RCTWorkAdvance 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).RCTWorkplace 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.RCTWorkplace 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.RCTYearUp 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
