Matching on the Estimated Propensity Score
Propensity score matching estimators (Rosenbaum and Rubin, 1983) are widely used in evaluation research to estimate average treatment effects. In this article, we derive the large sample distribution of propensity score matching estimators. Our derivations take into account that the propensity score is itself estimated in a first step, prior to matching. We prove that first step estimation of t...

متن کاملProof of Proposition 1 in : “ Matching on the Estimated Propensity Score ” ( Abadie and Imbens , 2012 )
Lemma A.1 Consider two independent samples of sizes n0 and n1 from continuous distributions F0 and F1 with common support: X0,1, . . . , X0,n0 ∼ i.i.d. F0 and X1,1, . . . , X1,n1 ∼ i.i.d. F1. Let N = n0 + n1. Assume that the support of F0 and F1 is an interval inside [0, 1]. Let f0 and f1 be the densities of F0 and F1, respectively. Suppose that for any x in the supports of F0 and F1, f1(x)/f0(...
متن کاملA Propensity Score Matching Analysis
The purpose of this paper is to determine how much is the “bonus” or “prize” to the sales per worker of Internet-using firms compared to not Internet-using firms. The author employs matching techniques based on an Argentinean database. The author first presents a binary logit model, in which the dependent variable is a dichotomous variable equal to 1 if the firm adopted Internet and 0 otherwise...
متن کاملThe Effect of Inflation Targeting on Indirect Tax Performance in Selected Countries Using Propensity Score Matching Model
Inflation targeting framework has become a predominant monetary approach across the globe. Williams (2015) believes that in a very real sense, almost all economies are inflation targeters -either explicit or implicit- now.(1) Due to the increasing spread of this policy, it is necessary to consider the way it affects macroeconomic variables. using prevalent economic models for evaluating the eff...
