摘要：We study communication in social networks prior to a majority vote on two alternative policies. Some agents receive a private imperfect signal about which policy is correct. They can recommend a policy to their neighbors in the social network prior to the vote. We show theoretically and empirically that communication can undermine efficiency and hence reduce welfare in a common-interest setting. Both efficiency and existence of fully informative equilibria in which vote recommendations are tru...

摘要：We extend the global games method to the class of finite player, finite action games that includes games with strategic complements, games with strategic substitutes, and arbitrary combinations of the two. Our result is based on common order properties present in both strategic complements and substitutes, the notion of p-dominance, and the use of dominance solvability as the solution concept. In addition to being closer to the original arguments in Carlsson and van Damme (1993), our approach ...

摘要：We study the effect of rigid and flexible bid caps on contestants' aggregate costs and aggregate bids in all-pay contests with a large number of heterogeneous contestants and prizes. We show that rigid caps always decrease aggregate costs, whereas flexible caps have essentially no effect on aggregate costs. Rigid caps decrease aggregate bids when costs are linear or concave, but increase aggregate bids under some conditions when costs are convex. Flexible caps always decrease aggregate bids. (...

摘要：We explore evolutionary dynamics for repeated games with small, but positive complexity costs. We begin by extending a folk theorem result by Cooper (1996) to continuation probabilities, or discount rates, smaller than 1. Then we show that All D has a uniform invasion barrier. Since none of the more cooperative equilibria are robust against indirect invasions, we might expect not to observe any cooperative equilibria when complexity costs are positive. The average level of cooperation in the d...

摘要：At the beginning of a dynamic game, players may have exogenous theories about how the opponents will play. If these theories are commonly known, players will refine their first-order beliefs and challenge their own theories through strategic reasoning. I propose a new solution concept, Selective Rationalizability, which captures the following hypothesis: when the observed behavior is not compatible with the beliefs in rationality and in the theories of all orders, players keep the beliefs in r...

摘要：This study reports a continuous-time experimental test of evolutionary models in coordinated attacker-defender games. It implements three experimental treatment conditions: one with strong coordination incentives, one with weak coordination incentives, and one with zero coordination incentives. Each treatment exhibits identical equilibrium predictions but distinct evolutionary predictions. Observed behavior was tightly clustered around equilibrium under both the zero coordination treatment and...

摘要：In many countries, three or more candidates compete against one another in single-office elections. I present a model of three candidates competing for a single office in which two candidates can form a coalition prior to the election (a pre-electoral coalition). Since the candidates are both policy- and office-motivated, one candidate can incentivize the other candidate to withdraw his candidacy by choosing a joint policy platform. I examine how electoral environments such as election rules, ...

摘要：School districts that implement stable matchings face various decisions that affect students' assignments to schools. We study the properties of the rank distribution of students with random preferences when schools use different tie-breaking rules to rank equivalent students. Under a single tie-breaking rule, where all schools use the same ranking, a constant fraction of students are assigned to one of their top choices. In contrast, under a multiple tie-breaking rule, where each school indep...

摘要：Revolutionary vanguards, their radicalism and coercive actions, and their interactions with ordinary citizens and the state are common threads in narratives of revolutionary movements. But what are the defining features of revolutionary vanguards? The literature is replete with terms that allude to some notion of a revolutionary vanguard (e.g., revolutionary entrepreneurs, entrepreneurs of violence, early -risers), but the essence of these conceptions and their implications for revolutionary p...
