Methods & evidenceCatchment Cohort Size InstrumentThe first-stage F-statistic was 23.54 without controls and 10.32 with controls, yielding an IV elasticity estimate of household expenditure to rule-based grants of -0.946 to -1.124 (p < 0.01).Observational StudyMethods & evidenceExogenous Failure AssignmentAmong the subset forced into the difficult task who failed in Round 1 (N = 558 in Sample A, N = 522 in Sample B), treated students re-attempted the difficult task in Round 2 at rates 17.6 percentage points higher in Sample A (p = 0.002) and 13.9 percentage points higher in Sample B (p = 0.064) than control group baseline rates of 36% and 51%.RCTEconomics (general)Lottery-Based Instrumental Variable Identification StrategyFirst-stage F-statistics exceed standard weak-instrument thresholds, showing that winning a lottery increases SYEP participation by over 50 percentage points, isolating clean local average treatment effects (LATE) free from selection bias.RCTLabour & employmentRandomized 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).RCT
