摘要：We consider a Paired Kidney Exchange (PKE) model in which patients' preferences are restricted so that patients prefer kidneys from compatible younger donors to kidneys from older ones. We propose a family of rules, sequential priority rules, that only allow for pairwise exchanges and satisfy individual rationality, efficiency, strategy-proofness, and non-bossiness. These rules allocate kidneys according to a priority algorithm that gives priority to patients with younger donors and assign kid...

摘要：We report on an experiment on decentralized markets in the presence of adverse selection. When allowing for costless and non-binding communication (cheap-talk), there exists a partially separating equilibrium that results in a substantially higher efficiency level than the adverse selection benchmark. The partially separating equilibrium hinges on the presence of matching frictions, which create a trade-off for low quality sellers between successfully mimicking high quality sellers and an incr...

摘要：We consider the possibility that cooperation in a prisoner's dilemma is fostered by people's voluntary enhancement of their own vulnerability. The vulnerability of a player determines the effectiveness of possible punishment by the other. In the Gradual mechanism, players may condition their incremental enhancements of their vulnerability on the other's choices. In the Leap mechanism, they unconditionally choose their vulnerability. In our experiment, subjects only learn to cooperate when eith...

摘要：We study which factors in terms of trading environment and trader characteristics determine individual information acquisition in experimental asset markets. Traders with larger endowments, existing inconclusive information, lower risk aversion, and less experience in financial markets tend to acquire more information. Overall, we find that traders overacquire information, so that informed traders on average obtain negative profits net of information costs. Information acquisition and the asso...

摘要：An evaluator estimates as precisely as possible the innate talent of a careerist expert by observing the expert's performance in a prediction task, and has the ability to interfere with the expert's private signal by affecting its precision. The expert on the other hand knows her talent, observes this interference and can misrepresent private beliefs through strategic predictions to enhance her reputation. We show that when priors are significantly uninformative so that the task is a priori ha...

摘要：Games in which players aim to guess a fraction or multiple p of the average guess are known as guessing games or (p -)beauty contests. In this note, we derive a full characterization of the set of rationalizable strategies and the set of pure strategy Nash equilibria for such games as a function of the parameter p, the number of players and the (discrete) set of available guesses to each player.

摘要：I consider the strategic manipulation problem in multistage tournaments. In each stage, players are sorted into groups in which they play pairwise matches against each other. The match results induce a ranking over players in each group, and higher ranked players qualify to the next stage. Players prefer qualifying to higher stages. In this setting, a player may potentially profit by exerting zero effort in some matches even when effort exertion is costless. Since such behavior manipulates the...

摘要：A learning rule is completely uncoupled if each player's behavior is conditioned only on his own realized payoffs, and does not need to know the actions or payoffs of anyone else. We demonstrate a simple, completely uncoupled learning rule such that, in any finite normal form game with generic payoffs, the players' realized strategies implements a socially optimal coarse correlated (Hannan) equilibrium a very high proportion of the time. That is, the empirical frequency associated with the pla...

摘要：We conduct a bargaining experiment where interaction is tacit and payoffs are earned and cumulated in real time. We test hypotheses about the interaction between the focal properties of payoffs and the complexity of coordinating on an intertemporal behavior that achieves them. The general finding is that when a payoff focal outcome requires a complicated coordination scheme bargainers tend to settle on a simpler and sometimes inefficient behavior. (C) 2017 Elsevier Inc.

摘要：This paper explores the behavior of a decision maker (DM) who is unaware of some of the options available to her. The DM has a preference over consumption alternatives that is informed by her epistemic state: what she knows and what she is aware of. The main result is a characterization, via observable choice, of introspective unawareness a DM who is both unaware of some information and aware she is unaware. Under dynamic introspective unawareness, the DM is unwilling to commit to future choic...
