摘要：For object reallocation problems, TTC is the leading rule: if preferences are strict but otherwise unrestricted, it is the only rule satisfying efficiency, the endowments lower bounds, and strategy-proofness (Ma, 1994); moreover, it is the only rule satisfying the endowments lower bounds, strategy-proofness, and endowment-swapping-proofness (Fujinaka and Wakayama, 2018). We focus on the domain of single-dipped preferences, and ask whether these results hold there. We show that they do. Returni...

摘要：We test whether deviations from Nash equilibrium in rent-seeking contests can be explained by the slow convergence of payoff-based learning. We identify and eliminate two noise sources that slow down learning: first, opponents are changing their actions across rounds; second, payoffs are probabilistic, which reduces the correlation between expected and realized payoffs. We find that average choices are not significantly different from the risk-neutral Nash equilibrium predictions only when bot...

摘要：This paper examines the signaling role of prices in a context of salient thinking. Consumers cannot observe product quality directly, and they focus on the product attribute - either quality or price - that stands out in the market. Our analysis shows that salience considerations mitigate the incentive to signal quality via price. Moreover, depending on the difference in quality between products, the separating price of the high-quality seller can be inflated or deflated in relation to a set-u...

摘要：We develop a prior-free mechanism for an asset market that is dominant-strategy incentive compatible, ex post individually rational, constrained efficient, and asymptotically optimal- as the number of agents grows large, the designer's profit from using this mechanism approaches the profit it would optimally make if it knew the agents' type distribution at the outset. The direct implementation first identifies the agent whose value equals the Walrasian price. The second step can be described a...

摘要：We examine how repeated interaction can facilitate coordinated turn-taking in a two-player infinitely repeated Volunteer's Dilemma. We conjecture that repetition creates an environment for players to coordinate on the Pareto efficient, but asymmetric pure strategy Nash equilibria of the stage game by taking turns volunteering. We consider three cost treatments: both players have the same cost; one player has a higher cost and this cost assignment is constant; one player has a higher cost and t...

摘要：We study an environment where an informed sender has conflicting interests with an uninformed receiver only in some states. Using an infection-like argument, we show that with symmetric loss functions, the presence of such disagreement states -even if they are very rare -leads to coarse communication in all states, even those where, following communication, it is commonly known that the players' interests are perfectly aligned. However, with asymmetric loss functions, one can construct example...

摘要：We prove that if each generation cares, non-paternalistically, about other generations' wellbeing rather than about their choices, and do not curb or otherwise alter future generations' choice sets, then backward induction intergenerational choice paths are efficient. This somewhat surprising result implies that intergenerational inefficiencies, to the extent that they do occur, are not due to different generations having different preferences, and prior generations trying to tip the scales in...

摘要：We generalize the notion of convexity and average-convexity to the notion of weighted average-convexity. We show several results on the relation between weighted average-convexity and cooperative games. Our main result is that if a game is weighted average-convex, then the corresponding weighted Shapley value is in the core.(c) 2023 Elsevier Inc. All rights reserved.

摘要：We generalize the standard, private values voting model with single-peaked preferences and incomplete information by introducing interdependent preferences. Our main results show how standard mechanisms that are outcome-equivalent and implement the Condorcet winner under complete information or under private values yield starkly different outcomes if values are interdependent. We also propose a new notion of Condorcet winner under incomplete information and interdependent preferences, and disc...

摘要：Should a political leader first focus on smaller policy goals or start with the most ambitious policy agenda? We model a political leader who chooses the policy agenda and proposes policies to a responder. The leader has a high or low ability to persuade the responder to agree to a proposal, and both parties are symmetrically uninformed about this ability. If the belief about the leader's ability is low, then it is optimal to start with the ambitious policy, but the reverse is true if the beli...
