The above estimand is applicable only when all the treated units are matched. As in our case when all treated units are not matched then SATT changes to LSATT or local sample average treatment for the treated and the estimands consequently changes to: where mT = number of matched treated units Tm = set of matched treated units For the unmatched treated units we extrapolate via some model estimands on the matched units to obtain virtual control units and obtain an estimate of the estimands. The overall SATT is then calculated as the weighted average of the two estimates for matched and unmatched treated units (Iacus et al., 2011) Results Summary Statistics of Raw Data Tables 1 and 2 shows the summary statistics for interval scale and categorical variables for the treated and control villages respectively. On an average, the number of household members engaged in agriculture varies from a little over 2 in case of control villages to a little over 2.5 in case of treated villages. Household members engaged in education have average highest education of 5.89 years in treated villages to 7.42 years in control villages. Average highest experience of household members currently engaged in agriculture varies very little among the treated and control villages, being around 28 years. Farm households on an average cultivate 5.70 bighas and 6.53 bighas of land in treated and control villages respectively and hence are mostly marginal farmers as per land size classification. In terms of formal sources of credit, lower proportion of farm households
