摘要：Is it better to present evidence first or second in trials if witnesses cannot lie, and the litigants share all available witnesses? We address this question by defining preferences over playing games via their equilibrium correspondences. Exploiting this partial ordering over games, we show that litigants cannot prefer to lead, but can prefer to follow; the judge/jury may also prefer some litigant to lead, but only if the litigants each prefer to follow. Allowing a litigant to choose whether ...

摘要：We investigate equilibrium in the buyer's bid double auction (BBDA) in a model with correlated private values/costs. Using a combination of theorems and computed examples, we demonstrate that simple equilibria exist even in small markets. Moreover, we bound traders' strategic behavior as a function of market size and derive rates of convergence to zero of (i) inefficiency in the allocation caused by strategic behavior and (ii) the error in the market price as an estimate of the rational expect...

摘要：Ambiguous language is ubiquitous and often deliberate. Recent theoretical work (Bose and Renou, 2014; Kellner and Le Quement, 2018; Beauchene et al., 2019) has shown how language ambiguation can improve outcomes by mitigating conflict of interest. Our experiment finds a significant effect of language ambiguation on subjects who are proficient at Bayesian updating. For ambiguity averse subjects within this population, a significant part of this effect operates via the channel of subjects' desir...

摘要：We consider a pricing problem where a buyer is interested in purchasing/using a good, such as an app or music or software, repeatedly over time. The consumer discovers his value for the good only as he uses it, and the value evolves with each use. In this paper, we explore the performance of a class of pricing mechanisms that are extremely simple for both the buyer and the seller to use: the seller offers the product for free for a certain number of uses, and then charges an appropriate fixed ...

摘要：We study effort provision and the development of the belief that effort matters over time: a student is uncertain whether she has control over success through her effort or whether success is determined by her innate ability, which she also does not know. In each period, what she can learn about her control and her ability depends on the level of effort she exerts. The student's optimal effort policy in this two-dimensional bandit problem takes the form of a linear belief cutoff rule and typic...

摘要：We consider a model where players can actively form a limited number of links with other players to play a general class of size-dependent coordination games. This class of games includes multi-person binary action coordination games, minimum effort games, average opinion games, and others, and it is mainly characterized by strategic complementarities among actions. Whenever players may only support links to a relatively small number of other players, the most efficient convention will be sele...

摘要：We investigate the influence of self and social image concerns as potential sources of lying costs across two studies (n = 991). In Experiment 1, in a standard die-rolling paradigm, we exogenously manipulate self-awareness and observability, which direct the focus of a person on their private and public selves, respectively. We find that our self-awareness manipulation has no effect on overreporting in comparison to a control treatment, while our observability manipulation significantly decrea...

摘要：Let V be a society whose members express weak preferences about two alternatives. We show simple representation formulae that are valid for all, and only, the elements of various classes of non-manipulable social choice functions on V. We represent the entire class of the non-manipulable social choice functions, and various of its subclasses corresponding to further properties. We focus mainly on anonymity. Efficiency and neutrality up to one voter are also considered. As a consequence of the ...

摘要：In this paper we study probabilistic Owen-Shapley spatial power indices, which are generalizations of the Owen-Shapley spatial power index (1977). We provide an explicit formula for calculating these spatial indices for unanimity games and give an axiomatic characterization of the family of probabilistic Owen-Shapley spatial power indices. We employ an equal power change property, a spatial dummy property, anonymity, a positional invariance property, and a positional continuity property. Some ...

摘要：In this note, I explore the implications of informational robustness under the assumption of common belief in rationality. That is, predictions for incomplete-information games which are valid across all possible information structures. First, I address this question from a global perspective and then generalize the analysis to allow for localized informational robustness. (C) 2022 Elsevier Inc. All rights reserved.
