In the presence of social dilemmas, cooperation is more difficult to achieve when populations are heterogeneous because of conflicting interests within groups. We examine cooperation in the context of a non-linear common pool resource game, in which individuals have unequal extraction capacities...

Consider a game whose strategies are "contributions". A strategy profile is a Kantian equilibrium if no player would like all players to alter their contributions by the same multiplicative factor. Kantian equilibria are Pareto efficient. We characterize the allocation rules on several domains...
