EducationDiscontinuity Assignment IdentificationRD estimates confirmed that direct learning gains for tutored students approached 1.00 standard deviation, while untutored peers above the rank cutoff showed no statistically significant indirect benefits.RCT Methods & evidenceFinancial Outcome WinsorizationWinsorization bounded weekly remittance amounts (control mean 2,338.50 PhP), stabilizing regression estimates across full sample (p = 0.81) and low-baseline subsample (+174.94 PhP, p < 0.05) specifications.RCT Methods & evidenceIndirect Inference Structural EstimationThe structural parameters matched the reduced-form empirical moments (treatment exit rate, control exit rate, regional comparison exit rate, and vacancy response curves), validating structural policy simulation counterfactuals.Expert Theory Methods & evidenceIntention-to-Treat (ITT) InstrumentationIn Year 2 in Mumbai, 33% of schools assigned to receive a balsakhi tutor did not receive one due to administrative difficulties; 2SLS instrumentation successfully eliminated non-compliance bias to yield unbiased direct treatment estimates.RCT Methods & evidenceKling Summary Index AggregationThe Kling labeling index demonstrated a statistically significant treatment take-up effect (mean index = 1.233, t = 44.445, p < 0.001) and a statistically significant overall remittance increase in the low-baseline subsample (+0.027 index units, p < 0.01).Observational Study Economics (general)Instrumental Variables Correction for Management Measurement ErrorThe IV point estimate for Total Factor Productivity (TFP) was 0.477 (p < 0.05, First-stage F-stat = 86.00) compared to an OLS estimate of 0.167, while the IV effect on quality defects was -1.694 compared to -0.558 under OLS, proving that uninstrumented estimates suffer from substantial downward attenuation bias.RCT Labour & employmentPre-Experimental Out-of-Sample Predictive ProfilingThe historical model successfully stratified the experimental sample into 1,688 high-employability ($\le 6$ months) and 2,475 low-employability ($> 6$ months) individuals, correctly identifying 87% of long-duration cases in baseline data without endogenous stratification bias.RCT Economics (general)Small-Sample Large-T Econometric Experimental DesignIntention-To-Treat (ITT) permutation tests demonstrated statistically significant reductions in quality defects (p = 0.001) and output increases (p = 0.026), proving that high-frequency weekly panel data compensates for small cross-sectional sample size.RCT Labour & employmentUncensored 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.RCT
