Abstract

Our experimental design mimics a traditional evolutionary game framework where players are matched pairwise to play a symmetric 3x3 bimatrix game which has two Nash equilibria. One equilibrium is an evolutionary stable state, or ESS; the other is an equilibrium in dominated strategies. Our primary experimental result is the observation that the ESS becomes extremely attractive when subjects have minimal information about the payoff functions although the dominated equilibrium assures the highest equilibrium payoff. The attractiveness of the ESS is only moderate when players are completely informed about the 3x3 payoff matrix.
