Efficient equilibrium selection in evolutionary games with random matching

The Pareto-superior equilibrium has been chosen in the key class of 2x2 coordination games. Using the KMR approach, the Pareto-superior equilibrium was adopted even if not risk-dominant. Convergence to the invariant distribution has been shown to be relatively fast. Sensitivity of the major properties of the KMR model has been investigated to the exact specification of the mechanism that matches individuals in each stage of play.
