Before revision:  We derive the asymptotic properties of inverse probability weighted estimators for the average, distributional  and quantile treatment effects based on the IPS and illustrate their relative performance via Monte Carlo simulations and three empirical applications. An implementation of the proposed methods is provided in the new packageIPS forR .
