Estimating Average Treatment Effects: Supplementary Analyses and Remaining Challenges
平均处理效应估计:补充分析与尚存挑战
There is a large literature on semiparametric estimation of average treatment effects under unconfounded treatment assignment in settings with a fixed number of covariates. More recently attention has focused on settings with a large number of covariates. In this paper we extend lessons from the earlier literature to this new setting. We propose that in addition to reporting point estimates and standard errors, researchers report results from a number of supplementary…
