. 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 …

, 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 …

Matching estimators (Rubin, 1973a, 1977; Rosenbaum, 2002) are widely used in statistical data analysis. However, the … large sample distribution of matching estimators has been derived only for particular cases (Abadie and Imbens, 2006). This … article establishes a martingale representation for matching estimators. This representation allows the use of martingale …

Matching estimators are widely used for the evaluation of programs or treatments. Often researchers use bootstrapping … neighbor matching, the standard conditions for the bootstrap are not satisfied, leading the bootstrap variance to diverge from …

selection--on--observables type assumptions using matching or propensity score methods. Much of this literature is highly …
