Findings that have different viewpoints aren’t taken into consideration to assess the ATT. 2nd, we show harmony regarding covariates and you can common service screening into the order to be transparent towards estimate. 3rd, OLS estimators together with have problems with new curse of multidimensionality. And finally, the fresh new PSM estimator will not demand as much limits into practical mode since OLS.
