【摘要】We propose a theory of unequal social norms, or conventions, where unequal practices persist over long periods of time despite being inefficient and not supported byformal institutions. We extend the standard asymmetric stochastic evolutionary game model to allow sub population sizes to differ and idiosyncratic rejection of a status quo convention to be intentional to some degree (rather than purely random as in the standard evolutionary models), consistent with historical cases. In this setting, if idiosyncratic play is sufficiently intentional and the subordinate class sufficiently large relative to the elite, then risk-dominated conventions that are both unequal and inefficient relative to alternative conventions can be stochastically stable and will persist for long periods. We show that the same is true in a general bipartite network of the population if most of the subordinate groups interactions are local, while the elite is more “cosmopolitan”. We illustrate the model with a number of historical transitions.
