Economics (general)Observational Study
Average Effect Size (AES) Quality Indexing
Combining multiple peer quality indicators (mean college entrance exam scores, dropout rates, remedial programs, matriculation fees) into an AES index revealed that voucher winners attended schools with statistically significant lower observable peer quality across academic indicators.
Economics (general)RCT
Frequentist Variance Bounding in Adaptive Trials
Bounded the worst-case standard error of estimated average treatment effects at $\sqrt{2\lambda} = 0.05$ (equivalent to 80% power for detecting effect sizes of 0.124), resulting in an actual empirical standard error bound of 0.016 in the trial.
