Note: All regressions also include controls as in Table 1. See online Appendix B for variable definitions. Effect size is measured as treatment coefficient divided by the standard deviation of control group in endline for a continuous variable and the mean of control group in endline for a dummy variable. Standard errors are clustered at the locality level. ***p < 0.01, **p < 0.05, *p < 0.1. The Family Wise Error Rate (FWER) adjusted p-value was estimated using the free step-down resampling approach of Westfall and Young (1993).
