Propensity score matching is a nonparametric technique frequently used for estimating average treatment effects. Yet … its applicability is not confined to treatment evaluation. In this paper the propensity score property is generalized to … the setting of selection on unobservables. It is shown that propensity score matching can be used to decompose effects due …

This paper reviews the main identification and estimation strategies for microeconometric policy evaluation. Particular … nonparametric matching and weighting estimators of the average treatment effects and their properties are examined. …
