Abstract
The analysis of large two-sided many-to-one matching markets available to date focuses on the class of responsive preferences. This paper gives the first thorough analysis of large market matching under the wider class of substitutable preferences satisfying the Law of Aggregate Demand. We show that the central results of Kojima and Pathak (2009) establishing vanishing incentives to misreport hold under these more general preferences. In doing so, we apply the characterization of stable matchings developed in Hateld and Milgrom (2005) to extend the foundational large market matching theorems not only to more general preferences, but also to arbitrary stable mechanisms. This analysis culminates in the first proof that truthful reporting constitutes an epsilon Nash equilibrium in large markets for all agents under any stable mechanism.
