Evolutionary game theory studies the robustness of strategy profiles and sets of strategy profiles with respect to evolutionary forces in games played repeatedly in large populations of boundedly rational agents. The approach is macro oriented inthe sense of focusing on the strategy distribution...

This paper examines equilibrioum and stability in symmetric two-player cheap-talk games. In particular, we characterize the set of neutrally stable outcomes in finite cheap-talk 2x2 coordination games.

In the models of Young (1993a,b), boundedly rational indivudals are recurrently matched to play myopic best replies to the recent history of play. It could therefore be an advantage to instead play a myopic best reply tthe myopic best reply, something boundedly rational players might conceivably...

This paper analyzes the interplay between economic incentives and social norms in a public finance context. We assume that to live one's own work is a social norm, and that the larger the population fraction adhering to this norm, the more intensely it is felt by the individual.

This paper provides deterministic approximation results for stochastic processes that arise when finite populations of boundedly rational agents recurrently play finite games. The deterministic approximation is defined in continuous time in terms of a system of ordinary differential equations of...

We derive a family of probabilistic choice models including the multinomial logit model, from a microeconomic model in which the decision maker has to make some effort in order to avoid mistakes when implementing any desired outcome. The disutility of this effort enters the decision maker's goal...

Bergin and Lipman (1996) show that the refinement effect from the random mutations in the adaptive dynamics in Kandori, Mailath and Rob (1993) and Young (1993) is due to restrictions on how these mutation rates vary across population states. We here model these mutation rates as endogenously...
