The standard method when analyzing the problem of cooperation using evolutionary game theory is to assume that people are randomly matched against each other in repeated games. In this paper we discuss the implications of allowing agents to have preferences over possible opponents. We model...

A simple symmetric 2 "e 2 strategic coordination game is analyzed in an evolutionary environment under the assumption that agents are able to condition their actions on observations made of the opponent. Agents are assumed to be associated with a profile of characteristics, of which all agents...

We analyze a cooperation game in an evolutionary environment. Agents make noisy observations of opponents' propensity to cooperate, called reputation, and form preferences over opponents based on their reputation. A game takes place when two agents agree to play. Pareto optimal cooperation is...
