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...

Ultimatum proposals and dictator donations are studied when proposers can choose the sex and income of the responder. Information about the responders' income generated strong effects in the selection of responders; subjects preferred to send proposals to low-income responders and the proposals...

The main purpose of this paper is to suggest a mechanism of coordination whereby concerns for high relative position might evolve endogenously. A simple symmetric 2 × 2 strategic coordination game is analyzed in an evolutionary environment where continua of bounded rational agents are randomly...

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

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...
