. Consider the following matching mechanism: take a random draw from the `W=w_j` subgroup of the first population and match her … function (AMF), denote the expected output associated with this match. We show that (i) the AMF is identified when matching is … conditionally exogenous, (ii) conditionally exogenous matching is compatible with a pairwise stable aggregate matching equilibrium …

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 …

, potentially complementary, input fixed. We introduce a class of such reallocations -- correlated matching rules -- that includes … the status quo allocation, a random allocation, and both the perfect positive and negative assortative matching …
