摘要：A platform offers sellers and buyers trading opportunities by creating one-to-one matches between them. A matching mechanism specifies subscription fees and the probabilities with which each seller type is matched with each buyer type. When the subscribers are fully strategic in their interactions with their matched partners, the optimal mechanism may not employ socially efficient positive assortative matching (PAM) but instead focus on the extraction of the agents' informational rents. In alt...

摘要：We study optimal employment contracts for present-biased employees if firms cannot commit to long-term contracts. Assuming that an employee's effort increases his chances to obtain a future benefit, we show that individuals who are naive about their present bias will actually be better off than sophisticated or time-consistent individuals. Moreover, firms might benefit from being ignorant about the extent of an employee's naivet & eacute;. Our results also indicate that naive employees might b...

摘要：This paper studies a multi-player lottery contest in which heterogeneous contestants exhibit reference-dependent loss aversion a la Ko?szegi and Rabin (2006, 2007). We verify the existence and uniqueness of pure-strategy choice-acclimating personal Nash equilibrium (CPNE) under moderate loss aversion and fully characterize the equilibrium. The equilibrium sharply contrasts with that in the two-player risk-neutral symmetric case. Loss aversion can lead contestants' individual efforts to change ...

摘要：A general condition called coarser traits is introduced and shown to be necessary and sufficient for the idealized limit property of large games with traits. Moreover, we illustrate the minimality of the coarser traits condition by showing its necessity in deriving the existence of pure-strategy Nash equilibria in large games with traits.

摘要：This paper models a scenario where finite perfect-information games are distorted in two ways. First, each player can have different possible levels of foresight, where foresight is a particular number of future stages that the player can observe/understand from each of her moves. In particular, each player's foresight is allowed to be limited or insufficient to observe the entire game from each move. Second, there is uncertainty about each opponent's foresight. I define the Limited Foresight ...

摘要：We consider evolutionary games on a population whose underlying topology of interactions is determined by a binomial random graph G(n, p). Our focus is on 2-player symmetric games with 2 strategies played between the incident members of such a population. Players update their strategies synchronously: each player selects the strategy that is the best response to the current set of strategies its neighbours play. We show that such a system reduces to generalised majority and minority dynamics. ...

摘要：We consider a fixed network of players endowed with idiosyncratic preferences over actions and involved in interactions of various types. The aim is to investigate the interplay between idiosyncratic preferences and interactional incentives on a network. The earlier literature demonstrated the conflict between players' intrinsic preferences and coordination incentives. This paper shows that such a conflict is also present in contexts in which players do not necessarily aim at coordination with...

摘要：We study generalized Shapley-Scarf exchange markets where each agent is endowed with multiple units of an indivisible and agent-specific good and monetary compensations are not possible. An outcome is given by a circulation which consists of a balanced exchange of goods. We focus on circulation rules that only require as input ordinal preference rankings of individual goods, and agents are assumed to have responsive preferences over bundles of goods. We study the properties of serial dictators...

摘要：The paper introduces coalition structures to study belief-free full implementation. When the mechanism designer does not know which coalitions are admissible, we provide necessary and almost sufficient conditions on when a social choice function is robustly coalitionally implementable, i.e., implementable regardless of the coalition pattern and the belief structure. Robust coalitional implementation is a strong requirement that imposes stringent conditions on implementable social choice functi...

摘要：This paper studies competitive bundling in an oligopoly market with one multi-product dominant firm and several symmetric small firms. In the model of (competing against) specialists each small firm produces a single product, while in the model of (competing against) generalists each small firm produces multiple products. In the model of specialists, we show that the dominant firm will bundle if and only if its dominance level is relatively high. In the model of generalists, the dominant firm'...
