MULTIPLICIDADE DE EQUILÍBRIOS E TRANSIÇÃO DE FASE EM UM MODELO DE CAMPOS ALEATÓRIOS PARA UM JOGO SOCIAL NÃO-COOPERATIVO
Gustavo Gomes de Freitas
Heron Carlos Esvael do Carmo
We apply the random fields framework proposed by Durlauf (1997) and Brock and Durlauf (2001) to a non-cooperative game of binary choices. We extend their model to allow for a more general distribution of the economic agents heterogeneity, in accordance with Glaeser and Scheinckman (2001). We analyze the existence and multiplicity of equilibria in that non-cooperative game, when agents can exhibit some interest to adjust their strategic behaviour to that prevailing in the aggregate. Depending on the conformity of players' behaviour, concerning the social average choice, there can be a multiplicity of equilibria.
