Heterogeneous Players and Specialized Models

Abstract

Game theory has been criticized as neglecting key aspects of individual behavior and as relying too heavily on special assumptions. It can, in fact, handle individual heterogeneity if the modeler is willing to carefully specify how people are different, but to the extent that such things as heterogeneity and culture are important, the desire for a single unified model is impossible to satisfy. At the same time, game theory's approach is very useful for building specialized models.
