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 کاملPropensity Score Matching for Multiple Treatments Comparison in Observational Studies
A major limitation of making inference about treatment effect based on observational data from a non-randomized study designs is the treatment selection bias, in which the baseline characteristics of population under one treatment could dramatically differ from the other one. If not handle properly, such sources of heterogeneity will introduce confounding effect into causaleffect relationship a...

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 کاملConsequences of Traffic Accidents Transferred by Helicopter and Ground Ambulance: Propensity Score Matching
Introduction: The main task of the emergency medical system is to provide primary care and transfer the injured to a medical center. Studies have been conducted to investigate the outcome of helicopter and ground ambulance casualties, but they show different results. These different results may be due to the type of study, statistical methods, differences in pre-hospital emergency systems, an...
