We study symmetric play in a class of repeated games when players are patient. We show that, while the use of symmetric strategy profiles essentially does not restrict the set of feasible payoffs, the set of equilibrium payoffs is an interesting proper subset of the feasible and individually...

Consider a symmetric 2-player game of complete information. Consider an arbitrary Bayesian extension of that game with payoff-irrelevant types, independent random matching, and anonymity (private types). We show that, in this setting, while strategies in a Bayesian Nash equilibrium of that game...

We use a model of impressionable voters to study multi-candidate elections under different electoral rules. Instead of maximizing expected utility, voters cast their ballots based on impressions. We show that, under each rule, there is a monotone relationship between voter preferences and vote...

We study dismissal power in a simple bargaining model. Player 1 makes a (policy) proposal which player 2 may approve or reject. A proposal contains a random component. If the proposal is approved, then, after the policy realization, one of the two players can dismiss the agreement. First, we...

We propose a model of attentiveness in elections with impressionable voters under various electoral rules. Voters' behavior is determined by their attentiveness and impressions of candidates. We show that attentiveness is as important as voters' preferences for the outcome of the election....

We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...
