Notes: Robust standard errors clustered by village are shown in parentheses. Marginal effects are reported for all binary outcomes; OLS coefficients are reported for the continuous outcome (Model 4). For Model 4, the value of Wooldridge’s robust score of endogeneity is 4.38, with a p value of .0412.
