Nash equilibrium when players account for the complexity of their forecasts


  • Eliaz, Kfir


Nash equilibrium is often interpreted as a steady state in which each player holds the correct expectations about the other players` behavior and acts rationally. This paper investigates the robustness of this interpretation when players` preferences are affected by their forecasts about the other players. In particular, I analyze the case of lexicographic preferences in which the simplicity of forecasts is secondary to material payoffs.
