摘要：We present a model that investigates preference evolution with endogenous matching. In the short-run, individuals' subjective preferences influence partner selection and behavior in social interactions, impacting material payoffs. These payoffs, in turn, affect how preferences evolve in the long-run. To properly model the "match-to-interact" process, we combine stable matching and equilibrium concepts. Our analysis unveils that endogenous matching gives rise to a class of preferences that exhibit both homophily and efficiency. Such preferences stand out in the evolutionary process because they are able to force positive assortative matching and efficient play. Under incomplete information, a strong form of homophily, parochialism, is necessary for a preference to prevail in evolution, because stronger incentives are required to engage in self-sorting with information friction.
