Noisy equilibrium selection in coordination games

By perturbing symmetric coordination games à la Bryant [Bryant, J., 1983. Quarterly Journal of Economics 98, 525–528] we derive unique solutions, the noise-proof equilibria. Our results agree with the experimental findings in Van Huyck et al. [Van Huyck, J.B., R.C. Battalio and R.O. Beil, 1990. American Economic Review 80, 234–248] and have an interesting connection with the notion of potential. We also briefly discuss median games
