The model used to test this regression is a linear probability one, using the treatment variable as our dependent variable on all household characteristics and control variables. We use the F-test to check for exogeneity, under the null that all estimated regressors are equal to zero. Given that the F-test is 0.66, we fail to reject the null hypothesis and the identifying assumption of the paper holds. We compute robust standard errors. t-statistics in parentheses: *p < 0.05, **p < 0.01 and ***p < 0.001
