主题:Group Rationality and Group Stable Equilibrium

讲座简介

In a repeated game, a strategy profile is group stable with respect to some groups of players if it is immune to deviations by any of these groups. Accordingly, a subgame perfect equilibrium is stable with respect to all single-player groups. We introduce the concept of group rationality, which is an extension of individual rationality from single-player groups to multi-player groups. For a collection of groups, a group stable equilibrium outcome must be feasible and weakly group rational for these groups. On the other hand, any feasible and strictly group rational payoff vector can be supported by a group stable equilibrium when the discount factor is sufficiently close to one, a folk theorem result for group stable equilibrium.
