Traditional game theory studies strategic interactions in which the agents make rational decisions. Evolutionary game theory differs in two key respects: the focus is on large populations of individuals who interact at random rather than on small numbers of players; and individuals are assumed...

The function of a social norm is to coordinate people`s expectations in interactions that possess multiple equilibria. Norms govern a wide range of phenomena, including property rights, contracts, bargains, forms of communication, and concepts of justice. Norms impose uniformity of behavior...

An individualʼs learning rule is completely uncoupled if it does not depend directly on the actions or payoffs of anyone else. We propose a variant of log linear learning that is completely uncoupled and that selects an efficient (welfare-maximizing) pure Nash equilibrium in all generic...
