摘要：We extend the study of behavioural types in voluntary contribution games, adapting the elicitation method of Fischbacher et al. (2001) to a broader range of economic and strategic incentives. Our results in the standard VCM game align with previous findings in many respects; in particular, we identify one-quarter of participants as a distinctive group of strong conditional cooperators. We provide an explanation for the behaviour of this group by tracking their contribution strategies as the fi...

摘要：We show how symmetric equilibria emerge in general two-player contests in which skill and effort are combined to produce output according to a general production technology and players have skills drawn from different distributions. The model includes the Tullock (1980) and Lazear and Rosen (1981) models as special cases. Our paper provides intuition regarding how the contest components interact to determine the incentive to exert effort and sheds new light on classic comparative statics resul...

摘要：We consider a Prisoner's Dilemma model with a pre-play communication stage. Players get a disutility from deceiving others after sending a message of conditional cooperation. Each player's realized lying aversion cost is private information. We prove existence and characterize the (unique) symmetric perfect Bayesian equilibrium that maximizes cooperation. In this distinguished equilibrium, the frequency of cooperation decreases as material gains from lying (or losses from being deceived) incre...

摘要：We propose an alternative to the tree representation of extensive form games. Games in product form represent information with sigma-fields over a product set, and do not require an explicit description of the play temporal ordering, as opposed to extensive form games on trees. This representation encompasses games with continuum of actions and imperfect information. We adapt and prove Kuhn's theorem - regarding equivalence between mixed and behavioral strategies under perfect recall - for gam...

摘要：This paper explores multi-stage incomplete information games with common ambiguous information about states or types and ambiguity averse players. We characterize a belief formation process that allows players to take their knowledge about the structure of the game into account. This process leads to subjective rectangular ex-ante belief sets for all players. We show that given these sets of beliefs, players behave dynamically consistent. Therefore, using our belief formation process, we can e...

摘要：We consider a model where the same group of players is involved in more than one cooperative (transferable utility) game. A rule determines the payoffs per game, and for each player a utility function evaluates the resulting vector of payoffs. We assume that each player, independently, can make transfers of worth between different games, thereby affecting its payoff vector and, thus, utility. Two transfer systems are considered, resulting in two distinct noncooperative games, and the focus of ...

摘要：We explore risk preference elicitation when subjects choose directly from an exogenously specified set of lotteries. Our choice tasks differ incrementally, e.g., from choosing between two lotteries to selecting a portfolio from a continuous set of bundled Arrow securities, and from text to spatial presentation. Each subject completes multiple instances of five different tasks, and responses for each task are summarized in parametric (CRRA) and non-parametric (normalized risk premium) measures ...

摘要：A decision maker would like to delegate the acquisition of information to an expert, but is unable to observe the expert's actions, nor is she able to postpone the payment to the expert until the truth is revealed. If the expert can manipulate their report of the realized signal then incentivizing information acquisition is typically impossible. However, by hiring multiple experts and making the payments contingent on the entire vector of signals the decision maker can obtain useful informatio...

摘要：We present results from laboratory experiments studying statistical discrimination and affirmative action. We induce statistical discrimination in simple labor-market interactions between firms and workers. We then introduce affirmative-action policies that vary in the size and duration of a subsidy that firms receive for hiring discriminated-against workers. These different affirmative-action policies have nearly the same effect, and practically eliminate discriminatory hiring practices. Howe...

摘要：Consider a market with two substitute products and a sequence of consumers. The consumers are uncertain about the quality of each product but obtain some private information about it. Additionally, each consumer observes the purchase decisions of her predecessors but not their private information. Absent prices, the standard logic of herding is that all but finitely many consumers may, with positive probability, select the lower quality product. One perspective in the literature is that inform...
