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...

We study ultimatum bargaining games with asymmetric information regarding disagreement payoffs. Results from Mensch (2020) are used to find conditions under which a monotonic equilibrium exists in these games. A standard single crossing assumption implies the existence of a monotonic Nash...

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...
