Economics (general)Belief Updating Realignment from Wage TransparencyDisclosing true supervisor pay reduced the mean absolute difference between perceived supervisor pay and actual salary from 35,320 SLL in the control group to 482 SLL in the treatment group (p < 0.001), where only 30% held accurate beliefs at baseline (37% underestimated, 33% overestimated).RCTDevelopmentSoft Skill Enhanced Social Entitlement and Benefit UtilizationSoft skills training increased worker utilization of government pensions by 2.48 percentage points (p < 0.10; relative to control mean of 3.9%) and government-subsidized healthcare by 2.26 percentage points (p < 0.05; relative to control mean of 0.6%, representing a nearly four-fold increase).RCTLabour & employmentSignal 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 TheoryLabour & employmentInformational Labor Rights and Interview SignallingAt two months, the intervention increased Syrian job search rates by 4.7 percentage points (p = 0.123), job applications by 35% (0.423 applications, p = 0.072), wage employment by 4.7 percentage points (p = 0.036), and monthly earnings by 6.21 JOD (p = 0.092). Impacts decayed by four months to a 1.9 percentage point employment gain (p = 0.148).RCTLabour & employmentLabor Market Information Provision and Job FairsIn Ethiopia, job fairs corrected distorted beliefs about employment prospects and enhanced job search outcomes for job seekers with strong initial misconceptions. In the Philippines, a job fair sharing overseas labor market information increased the likelihood of seeking employment outside the local region and entering formal sector employment. In Germany, providing information about the job search process increased employment and earnings for workers at risk of long-term unemployment.RCTEducationLevel-Based vs. Value-Added Quality Signals in Parental DemandExploded logit specifications using raw average test scores yielded the best fit to observed choices (-log likelihood = -42,570 for non-lunch white elementary), whereas models using estimated school value-added fit observed choices poorly (-log likelihood = -43,751), demonstrating that parental decisions are driven by achievement levels rather than gains.Observational StudyLabour & employmentMatch 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).RCTLabour & employmentExternal 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.RCT
