Abstract

Joint with Srinivas Arigapudi and Amnon Schreiber.

The hawk-dove game admits two kinds of equilibria: asymmetric pure equilibria in which players in one population play `hawk' and players in the other population play `dove', and a symmetric mixed equilibrium. The existing literature on dynamic evolutionary models show that populations will converge into playing one of the asymmetric pure equilibria from any initial state. By contrast, we show that under plausible sampling dynamics, in which agents occasionally revise their actions by observing either opponents' behavior or own payoffs in a few past interactions, can induce the opposite result: global convergence to a symmetric mixed equilibrium.
