摘要：Are fairness and efficiency compatible in behavioral welfare economics? Assuming multi-self agents, who may not be able to integrate their various objectives into complete and transitive rankings, we call an allocation unambiguously-fair if it fair according to every self of every agent. We show that efficiency is generically compatible with the unambiguous fair-share guarantee, and - in two agent economies - with unambiguous no-envy. But in some larger economies, no efficient allocation satis...

摘要：We consider the equity-manipulability trade-off when voting over two alternatives. Pairwise equity is a weakening of anonymity requiring certain permutations of the voters' identities to preserve the outcome of the election. B-robust group strategy-proofness (t-RGSP) and fine robust group strategy-proofness (FRGSP) are notions of group strategy-proofness that allow voters to have different beliefs about players' types (Kivinen and Tumennasan, 2021). Our main results show that, under mild condi...

摘要：We experimentally investigate how the prize structure affects the intensity, fairness, and dynamic behavior in sequential round-robin tournaments with three players. We compare tournaments with a second prize equal to either 0%, 50%, or 100% of the first prize. While theory predicts the 50%-treatment to be most intense, we find that aggregate effort is highest in the 0%-treatment. In contrast, our evidence supports the predictions that the 50%-treatment is fairest (though not perfectly fair), ...

摘要：Pro-social risk-taking involves the willingness to commit resources to initiatives and opportunities with a social benefit, as well as a risk of costly failure. These situations often occur in an environment in which groups compete for resources. In these contexts of intergroup conflict, often individuals make personal sacrifices on a voluntary basis, involving considerable risks of failure. We study the context of pro-social risk-taking and intergroup conflict by extending the volunteer's dil...

摘要：We introduce a new approach to studying the existence of a monotone pure-strategy Bayesian-Nash equilibrium in an n-player single-prize contest model that covers both perfectly and imperfectly discriminating contests. The contestants have continua of possible types and bids, atomless type distributions, and their valuations and costs might depend not only on their own bids and types but also on other bidders' bids and types. Many, quite different contests are covered by our generalized contest...

摘要：We introduce informational punishment to the design of mechanisms that compete with an exogenous status quo mechanism: Players can send garbled public messages with some delay and others cannot commit to ignoring them. Optimal informational punishment ensures that full participation is without loss, even if any single player can publicly enforce the status quo mechanism. Informational punishment permits using a standard revelation principle, is independent of the mechanism designer's objective...

摘要：Lab evidence on trust games involves more cooperation than conventional economic theory predicts. We explore whether this pattern extends to a field setting where we are able to control for (lack of) repeat-play and reputation: the taxi market in Mexico City. We find a remarkably high degree of trustworthiness, even with price-haggling which was predicted to reduce trustworthiness.(c) 2023 Elsevier Inc. All rights reserved.

摘要：This paper studies the design of efficient mechanisms for repeated bilateral trade in settings where (i) traders' values and costs evolve randomly with time, and (ii) the traders become ready and available to participate in the mechanism at random times. Under a weak condition, analogous to the non-overlapping supports condition of Myerson and Satterthwaite (1983), efficient trade is only feasible if the mechanism runs an expected budget deficit. The smallest such deficit is attainable by a se...

摘要：We consider a constitution as a pair of voting rules (f, F) in which the given rule f is for the decision on the final outcome, and the base rule F is for the decision on the change of a voting rule. Which constitutions would stably survive? We define the concepts of interim/ex-post stability, whereby agents' preferences over the outcomes are privately/publicly known when they change a voting rule. We fully characterize the set of interim stable constitutions, which consist of anonymous voting...

摘要：We introduce a model of sender-receiver stopping games, in which the sender observes the current state, and sends a message to the receiver to either stop the game, or to continue. The receiver, only seeing the message, then decides to stop the game, or to continue. The payoff to each player is a function of the state when the receiver quits, with higher states leading to better payoffs. We prove existence and uniqueness of responsive Perfect Bayesian Equilibrium (PBE) when players are suffici...
