In his work on market signaling, Spence proposed a dynamic model of a signaling market in which a buyer revises prices in light of experience and sellers choose utility-maximizing signals given these prices. Spence also suggested that subjecting the dynamic process to rare perturbations might...

This paper develops an approach to equilibrium selection in game theory based on studying the equilibriating process through which equilibrium is achieved. The differential equations derived from models of interactive learning typically have stationary states that are not isolated. Instead, Nash...

We generalize traditional equilibrium concepts for finite games in extensive form with behavioral strategies so that they apply to all games, including games of imperfect recall. Adapting and augmenting previous de finitions (in particular, by Piccione and Rubinstein, and by Battigalli), we de...

This paper studies equilibrium refinements in signaling games through an examination of rationalizability in derived games obtained by replacing the equilibrium path with a sure outcome that yields the equilibrium payoff to all players. The informed player chooses between the sure payoff and...

We study the effects on the Nash equilibrium of the presence of a structure of social interdependent preferences in a Cournot oligopoly, described in terms of a game in which the network of interactions reflects on the utility functions of firms through a combination of weighted profits of their...

This paper shows that under very general conditions, there exists a locally stable Nash equilibrium in games of strategic complements (GSC), as well as in the more general case of games with non-decreasing best response correspondences. While it is well known that in such cases a unique...

I introduce a new framework to study environments with both structural and strategic uncertainty, different from Harsanyi's (1967-8) `Bayesian games', that allows a researcher to test the robustness of Nash predictions while maintaining certain desirable restrictions on players' beliefs. The...

This note applies the evolutionary dynamic of Kandori, Mailath, and Rob ( Econometrica 61 (1993), 29-65) to class coordination games that the entire population plays simultaneously. In these games, payoffs and best replies are determined by a symmary statistic of the population strategy profile...

This article considers the robustness of long run equilibria when mutation rates are not assumed to be constant over time. Particular attention is paid to the case where mutation rates decline to zero in the limit. It is found that if behaviour is ergodic, then it corresponds to the long run...
