This paper derives the conditions under which fitness-reducing alleles can survive in a longrun stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction

Teamwork and cooperation between workers can be of substantial value to a firm, yet thelevel of worker cooperation often varies between individual firms. We show that thesedifferences can be the result of labor market competition if workers have heterogeneouspreferences and preferences are...

In public good provision, privileged groups enjoy the advantage that some of its membersfind it optimal to supply a positive amount of the public good. However, their inherentasymmetric nature may make the enforcement of cooperative behavior through informalsanctioning harder to accomplish...

This paper reports an experiment which compares behaviour in two punishment regimes: (i) a standard public goods game with punishment in which subjects are given the opportunity to punish other group members (democratic punishment regime) and (ii) a public goods game environment where all group...

Reciprocal cooperation can be studied in the Centipede game, in which two players alternate in choosing between a cooperative GO move and a non-cooperative STOP move. GO sustains the interaction and increases the player pair's total payoff while incurring a small personal cost; STOP terminates...

Until recently, theorists considering the evolution of human cooperation have paid little attention to institutional punishment, a defining feature of large-scale human societies. Compared to individually-administered punishment, institutional punishment offers a unique potential advantage: the...

If actors want to reach a particular goal, they are often better off forming collaborative relations and investing together rather than investing separately. We study the coordination and cooperation problems that might hinder successful collaboration in a dynamic network setting. We develop an...

Who benefits from the ignorance of others? We address this question from the point of view of a policy maker who can induce some ignorance into a system of agents competing for resources. Evolutionary game theory shows that when unconditional cooperators or ignorant agents compete with defectors...
