Findings which have unlike philosophy aren’t considered so you can assess the fresh ATT. Second, i tell you balance from the covariates and you can prominent service tests during the purchase to-be clear regarding quote. 3rd, OLS estimators along with suffer with the fresh curse from multidimensionality. Finally, this new PSM estimator does not demand as much limitations into useful function once the OLS.
sixteen. The process for estimating it equation is like Formula (2), not in lieu of providing differences in the post-procedures several months, i plus grab differences in the new pre-procedures period.
