Propensity Score Matching∗ Propensity Score Matching (PSM) has become a popular approach to estimate causal treatment effects. It is widely applied when evaluating labour market policies, but empirical examples can be found in very diverse fields of study. Once the researcher has decided to

Apr 30, 2014 · Once a propensity score has been calculated for each observation, one must ensure that there is overlap in the range of propensity scores across treatment and comparison groups (called “common support”).Cited by: 383

Propensity score matching Basic mechanics of matching The matching criterion could be as simple as the absolute difference in the propensity score for treated vs. non-treated units. However, when the sampling design oversamples treated units, it has been found that matching on the log odds of the propensity score (p=(1 p)) is a superior criterion.

In case of non-parametric (semi-parametric) estimation (matching on X or on the propensity score) this assumption is crucial. However, I am wondering whether this assumption has to hold if I want to estimate the treatment effect in a parametric regression (e.g. a simple multivariate linear model fitted by OLS).

Rosenbaum and Rubin (1983) proposed propensity score matching as a method to reduce the bias in the estimation of treatment e ects with observational data sets. These methods have become increasingly popular in medical trials and in the evaluation of economic policy interventions. Grilli and Rampichini (UNIFI) Propensity scores BRISTOL JUNE ...

Propensity score / linear propensity score With propensity score estimation, concern is not with the parameter estimates of the model, but rather with the resulting balance of the covariates (Augurzky and Schmidt, 2001). Implementing a matching method, given that measure of closeness. Methods: k:1 Nearest Neighbor
