摘要：Do boundedly rational players learn to choose equilibrium strategies as they play a game repeatedly? A large literature in behavioral game theory has proposed and experimentally tested various learning algorithms, but a comparative analysis of their equilibrium convergence properties is lacking. In this paper we analyze Experience-Weighted Attraction (EWA), which generalizes fictitious play, best-response dynamics, reinforcement learning and also replicator dynamics. Studying 2 x 2 games for t...

摘要：The bilingual game is a simple variant of a coordination game in which players can choose between two alternative languages, but also have the option of a bilingual strategy, which allows them to coordinate with speakers of both languages at some additional cost. In this paper, we introduce heterogeneity in this cost and show how it leads to the persistence of the bilingual strategy in equilibrium. This helps to explain phenomena such as people using multiple pieces of software that can achiev...

摘要：Lately, there has been an increase in the use of sequential mechanisms, instead of the traditional direct counterparts, in college admissions in many countries, including Germany, Brazil, and China. We describe these mechanisms and identify their shortcomings in terms of incentives and outcome properties. We introduce a new mechanism, which improves upon these shortcomings. Unlike direct mechanisms, which ask students for a full preference ranking over colleges, our mechanism asks students to ...

摘要：We revisit the basic variant of the classical secretary problem. We propose a new approach in which we separate between an agent (the sender) that evaluates the secretary performance and one (the receiver) that makes the hiring decision. The sender signals the quality of the candidate to the hiring agent. Whenever the two agents' interests are not fully aligned, this induces an information transmission (signaling) challenge for the sender. We study the sender's optimization problem subject to ...

摘要：Central to this note is the concept of disjointly productive players. Two players are disjointly productive if there is no synergy effect if one of these players joins a coalition containing the other. Our first new axiom states that the payoff to a player does not change when another player, disjointly productive in relation to that player, leaves the game. The second new axiom implies that if a player splits into two disjointly productive players who together contribute the same to the game ...

摘要：In an information graph situation, a finite set of agents and a source are the set of nodes of an undirected graph with the property that two adjacent nodes can share information at no cost. The source has some information (or technology), and agents in the same component as the source can reach this information for free. In other components, some agent must pay a unitary cost to obtain the information. We prove that the core of the derived information graph game is a von Neumann-Morgenstern s...

摘要：We experimentally test whether increasing the salience of payoff-irrelevant focal points (Schelling, 1960) can counteract the negative impact of conflicts of interest on coordination. The intuition is that, in the presence of conflict, the solution to the coordination dilemma offered by the focal point loses importance. Increasing its salience increases its relevance and, therefore, coordination success. When we vary label salience between subjects, we find support for this conjecture in games...

摘要：In infinitely repeated games, Nachbar (1997, 2005) has shown that Bayesian learning of a restricted strategy set is inconsistent; the beliefs required to learn any element of such a set will lead best responses to lie outside of it in most games. But I establish here that Nash convergence of Bayesian learning requires only that optimal play (rather than any possible play) is learnable, and an appropriately modified notion of learnability is consistent in many of the games to which Nachbar's re...

摘要：Lemma 20 in Gori (2021) is not correct. In this note we propose a new version of Lemma 20 and we discuss the impact of that new version on the other results in Gori (2021). Notation and definitions are as in Gori (2021). (C) 2022 Elsevier Inc. All rights reserved.

摘要：We analyze the implications of consumers' limited perception in a model of horizontal product differentiation. Consumers with limited perception do not necessarily notice all goods in the market. Limited perception thus offers a market segmentation into consumers who notice only one good and consumers who notice all goods. Our objective is to analyze whether less perception is harmful to consumers when firms use this segmentation to price discriminate. We show that product differentiation unde...
