Note: Controls in all regressions include: pre-intervention outcomes (manual desludging in year before baseline) and fixed effects at the grid-point level. Standard errors are in parentheses: p<0.10, p<0.05, p<0.01. Outcome variables are (1) signed up for the subsidized mechanized desludging through the subscription, (2) purchased the subsidized mechanized desludging through the subscription, (3) purchased an unsubsidized mechanized desludging between the baseline and endline, and (4) purchased any mechanized desludging between the baseline and the endline. In the lower panel, ‘High subsidy if mech in year before baseline’ shows the value of the sum of the coefficient on ‘High subsidy’ and ‘High subsidy x Mechanized desludging in year before baseline,’ the heterogeneous treatment effect.
