Identification and Efficiency Bounds for the Average Match Function under Conditionally Exogenous Matching

Graham, Bryan S. - 2016

. 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 …
