摘要：We design a public goods laboratory experiment in both a virtual world environment and an abstract computerized environment, each with and without communication and visibility, to investigate how communication and visibility of other participants affect individual contributions to public goods. In both environments, the presence of communication significantly and consistently improves public good contributions. However, the interaction between communication and visibility differs in the two en...

摘要：We provide a sound and complete axiomatization for a class of logics appropriate for reasoning about the rationality of players in games, and show that essentially the same axiomatization applies to a very wide class of decision rules. We also consider games in which players may be uncertain as to what decision rules their opponents are using, and define in this context a new solution concept, D-rationalizability.

摘要：Players have privacy concerns that may affect their choice of actions in strategic settings. We use a variant of signaling games to model this effect and study its relation to pooling behavior, misrepresentation of information, and inefficiency. (C) 2017 Elsevier Inc. All rights reserved.

摘要：Simple majority does not reflect the intensity of voters' preferences. This paper presents an efficient collective choice mechanism with two alternatives when the designer may use non-transferable punishments to persuade agents to reveal their private information. The designer faces a dilemma - a punishment may induce a more correct choice, but its cost is socially wasteful. The efficient mechanism is a weighted majority. Weight of each individual is known ex ante and no punishments are applie...

摘要：We study continuous-time stochastic games, with a focus on the existence of their equilibria that are insensitive to a small imprecision in the specification of players' evaluations of streams of payoffs. We show that the stationary, namely, time-independent, discounting game has a stationary equilibrium and that the discounting game and the more general game with time-separable payoffs have an epsilon equilibrium that is an epsilon equilibrium in all games with a sufficiently small perturbati...

摘要：This paper analyzes two-stage rank-order tournaments. To influence efforts in the two periods, a principal can use the intertemporal prize structure and the weight of first-period performance in the second-period prize. These two instruments implement different sets of effort vectors. We characterize the optimal combination of prizes and weights as a function of parameters. For large parameter regions, the principal should only give a second-period prize, but use positive first-period performa...

摘要：We show that feasible elimination procedures (Peleg, 1978) can be used to select k from m alternatives. An important advantage of this method is the core property: no coalition can guarantee an outcome that is preferred by all its members. We also show that the problem of determining whether a specific k-tuple can result from a feasible elimination procedure is computationally equivalent to the problem of finding a maximal matching in a bipartite graph.

摘要：We study the information aggregation properties of unanimous voting rules in the laboratory. In line with theoretical predictions, we find that majority rule with veto power dominates unanimity rule. We also find that the strategic voting model is a fairly good predictor of subject behavior. Finally, we exploit a framing effect to study how the presence of less sophisticated agents affects Veto's welfare properties. (C) 2016 Elsevier Inc. All rights reserved.

摘要：In this spatial model of common-value elections, votes convey citizens' private opinions regarding which policies are socially optimal, and the winning candidate utilizes this information in choosing policy. In equilibrium, large margins of victory convey mandates for candidates to make bold policy changes. To communicate extreme policy views, citizens support extreme parties that may be unlikely to win office. To convey moderate views, citizens deliberately abstain from voting, thereby avoidi...

摘要：This paper considers all-pay contests in which the relationship between bids and allocations reflects a small amount of noise. Prior work had focused on one particular equilibrium. However, there may be other equilibria. To address this issue, we introduce a new and intuitive measure for the proximity to the all-pay auction. This allows, in particular, to provide simple conditions under which actually any equilibrium of the contest is both payoff equivalent and revenue equivalent to the unique...
