In a collective-action game a player`s payoff is the sum of (i) a private component that depends only on that player`s action, and (ii) a public component, common to all players and dependent upon all actions. A classic application is the private provision of a public good. Play evolves:...

A public good is produced if and only if a team of m or more volunteers contribute to it. An equilibrium-selection problem leads to the questions: will collective action succeed? If so, who will participate in the team? The paper studies the evolution of collective action: as part of a...

The volunteer`s dilemma is an asymmetric n-player binary-action game in which a public good is provided if and only if at least one player volunteers, and consequently bears some private cost. So long as the value generated for every player exceeds this private cost there are n pure-strategy...

This paper studies n-player collective-action games in which a public good is produced if and only if m or more volunteers contribute to it. Quantal-response strategy revisions allow play to move between equilibria in which a team of m players successfully provide, and an equilibrium in which...

A finite population of agents playing a 2 x 2 symmetric game evolves by adaptive best response. The assumption that players make mistakes is dropped in favor of one where players differ, via payoff heterogeneity. Arbitrary mutations are thus replaced with an economically justified specification....
