摘要：The prospect of receiving a monetary sanction for free riding has been shown to increase contributions to public goods. We ask whether the impulse to punish is unresponsive to the cost to the punisher, or whether, like other preferences, it interacts with prices to generate a conventional demand curve. In a series of experiments, we randomly vary the cost of reducing the earnings of other group members following voluntary contribution decisions. In our design, new groups are formed after each ...

摘要：A commonly held belief in economics is that an individual's preferences that are revealed by her choices must be complete. This paper takes issue with this position by showing that one may be able to distinguish between indifference and indecisiveness of an agent upon observing her choice behavior. We relax the standard Weak Axiom of Revealed Preferences (WARP) and show that a potent theory of individual choice (with and without risk) can be founded on this weaker axiom when it is coupled with...

摘要：In the framework of cooperative game theory, the concept of interaction index, which can be regarded as an extension of that of value, has been recently proposed to measure the interaction phenomena among players. Axiomatizations of two classes of interaction indices, namely probabilistic interaction indices and cardinal-probabilistic interaction indices, generalizing probabilistic values and semivalues, respectively, are first proposed. The axioms we utilize are based on natural generalizatio...

摘要：A seller sells dissimilar objects while taking the auction rule as given. Should the seller sell the objects separately or as a bundle? Generally, when the number of bidders is small bundling helps to stimulate the competition and raise revenue. In this paper, we show that if entry is costly enough the process of endogenous participation generates sufficient competition to make bundling unnecessary in auctions. Thus whether a bundle auction generates a higher or a lower revenue ultimately depe...

摘要：This paper studies a social game where agents choose their partners as well as their actions. Players interact with direct and indirect neighbors in the endogenous network. We show that the architecture of any nontrivial Nash equilibrium is minimally connected, and equilibrium actions approximate a symmetric equilibrium of the underlying game. We apply the model to analyze stochastic stability in 2 x 2 coordination games. We find that long-run equilibrium selection depends on a trade-off betwe...

摘要：We consider a panel of experts asked to assign probabilities to events, both logically simple and complex. The events evaluated by different experts are based on overlapping sets of variables but may otherwise be distinct. The union of all the judgments will likely be probabilistically incoherent. We address the problem of revising the probability estimates of the panel so as to produce a coherent set that best represents the group's expertise. (c) 2006 Elsevier Inc. All rights reserved.

摘要：The existence of a common prior is a property of the state space used to model the players' incomplete information. We show that this property is not just a technical artifact of the model, but that it is immanent to the players' beliefs. To this end, we devise a condition, phrased solely in terms of the players' mutual beliefs about the basic, objective issues of possible uncertainty, which is equivalent to the existence of a common prior. This condition specifies a countable sequence of ques...

摘要：We consider the consequences of competition between two types of experimental exchange mechanisms. a decentralized bargaining market, and a centralized market. It is shown that decentralized bargaining is subject to a process of unraveling in which relatively high value traders (buyers with a high willingness to pay and sellers with low costs) continuously find trading in the centralized markets more attractive until few opportunities for mutually beneficial trade remain outside the centralize...

摘要：A growing literature reports the conclusions that: (a) expected utility theory does not provide a plausible theory of risk aversion for both small-stakes and large-stakes gambles; and (b) this decision theory should be replaced with an alternative theory characterized by loss aversion. This paper explains that the arguments in previous literature fail to support these conclusions. Either concavity calibration has no general implication for expected utility theory or it has problematic implicat...
