Notes: p-values are reported from Wald tests on the equality of means of the attrition group and panel for columns (3) and (6) and treatment and control for column (8). Standard errors are clustered at the CWAC level. Of the 2,492 female transfer recipients at baseline 2,031 are in the panel sample and 444 lost to attrition at any wave and 17 lost to missing covariate data at baseline. We show unlogged values of per capital monthly expenditures for mean comparisons, however control for logged values in regression analyses.
