Voluntary Participation Game Experiments with a Non-Excludable Public Good: Is Spitefulness a Source of Cooperation?.

Economic theory predicts that it is impossible to have cooperation in finitely repeated games such as a prisoner's dilemma game without communication. In an experiment on a voluntary participation game with a non-excludable public good that is a version of a Hawk-Dove game, we obderved that evolutionary stable strategies did not appear, but cooperation emerged through a transmutation from the Hawk-Dove game to a game where a dominant strategy outcome is Pareto efficient.
