内容简介：

We develop a model of preference evolution with endogenous matching. In the short-run, individuals' subjective preferences influence partner selection and behavior in social interactions, which affects their material payoffs. These payoffs, in turn, affect how preferences evolve in the long-run. To properly model the "match-to-interact" process, we integrate stable matching and equilibrium concepts within a unified framework. Our analysis shows that purely efficient or purely selfish preferences cannot survive natural selection under endogenous matching. Instead, preferences that combine these considerations with inequality aversion or a form of morality can be evolutionarily stable. Such preferences stand out because they are able to force joint payoff maximization and equal payoff allocation. Under incomplete information, only the preference type that exhibits morality can prevail in evolution, because it provides stronger incentives to engage in sorting when information frictions are present.
