Labour & employmentAbility-Heterogeneous Wage ReturnsTreatment effects are significantly concentrated among lower-ability workers (interaction coefficient = -0.171, p < 0.05 for employment proportion; -0.568, p < 0.05 for log daily wages). Job seekers at the 25th ability percentile experience a 25 percentage point employment increase and an $11.01 daily wage increase, compared to a 1.5 percentage point employment decline and $2.20 wage increase for those at the 75th percentile.RCTLabour & employmentAsymmetric Productivity-Wage Pass-Through and Signaling BottlenecksWhile manager soft skills training increased team productivity by 5.8% and manager wages by 6%, frontline workers who achieved a 13.5% productivity gain and higher promotion rates received zero wage increase due to external signaling barriers.RCTLabour & employmentCausal Wage Returns to Short-Term Work ExperienceAcquiring 5 days of short-term work experience increased average daily wages by $3.83 (representing an approximate 80% wage increase) over the 8-month follow-up period and increased subsequent employment probability by 6.8 to 8.8 percentage points.RCTLabour & employmentDecoupling 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 StudyLabour & employmentInter-Firm Job Mobility for Wage GrowthOnly 13% of workers remained in the same job after 3 years; treated workers leveraged early job security and certified signals to switch firms successfully, sustaining a 20% wage premium over control workers (p < 0.05) without working longer current job tenures.RCTLabour & employmentNon-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.RCT
