Population games describe strategic interactions among large numbers of small, anonymous agents. Behavior in these games is typically modeled dynamically, with agents occasionally receiving opportunities to switch strategies, basing their choices on simple myopic rules called revision protocols....

This paper shows how strategic matching generates reputation-building behavior in an evolutionary chain-store game. Strategic matching means the possibility for an entrant to choose in a strategic way the local market into which it will move. Players are boundedly rational and follow behavioral...

We present a dynamic analysis of the evolution of preferences in a strategic environment. In our model, each player's behavior depends upon both the game's payoffs and his idiosyncratic biases, but only the game's payoffs determine his evolutionary success. Dynamics run at two speeds at once:...

Neuroeconomics focuses on brain imaging studies mapping neural responses to choice behavior. Economic theory is concerned with choice behavior but it is silent on neural activities. We present a game theoretic model in which players are endowed with an additional structure - a simple "nervous...

We call a correspondence, defined on the set of mixed strategy proles, a generalized best reply correspondence if it (1) has a product structure, (2) is upper hemi-continuous, (3) always includes a best reply to any mixed strategy prole, and (4) is convex- and closed-valued. For each generalized...

n this paper we propose a pluralistic and multi-dimensional ap- proach to cooperation. Specifically, we seek to show that, in certain settings, less unconditional forms of cooperation may be combined with more gratuitous ones. Starting with the prisoner’s dilemma game, the evolution of...

This paper studies the extent to which diffusion approximations provide a reliable guide to equilibrium selection results in finite games. It is shown that they do for a class of finite games with weak learning provided that limits are taken in a certain order. The paper also shows that making...

This paper introduces two new concepts in evolutionary game theory: Nash equilibrium with Group Selection (NEGS) and Evolutionarily Stable Strategy with Group Selection (ESSGS). These concepts generalize Maynard Smith and Price (1973) to settings with arbitrary matching rules, inparticular they...

We justify risk neutral equilibrium bidding in commonly known fair division games with incompleteinformation by an evolutionary setup postulating (i) minimal common knowledge, (ii) optimal responses to conjectural beliefs how others behave and (iii) evolutionary selection of conjectural beliefs...

We apply an indirect evolutionary approach to player’ perceived prize valuations in contests. Evolution in finite populations leads to preferences that overstate the prize’s material value and induce overexpenditure. We establish an equivalence between the behavior evolutionarily stable...
