Notes: ATT = Average Treatment Effect on the Treated. In the above table model 1 & 4 is Kernel matching; model 2 & 5 is Nearest Neighbor matching - random draw version; and model 3 & 6 is Inverse Probability Weighting (IPW) by logistic regression. The SES index is a binary variable based on having electricity at home and current employment status. The standard errors are bootstrapped standard errors. Significance levels: ***p < 0.01, **p < 0.05, *p < 0.1
