In this paper we show experimentally that conditional cooperation, a phenomenon described in the private provision of … determines if they overcome a rival group. This environment allows us to identify new determinants of conditional cooperation. We … observe conditional cooperation in successful groups and in groups where members contribute more than rivals (even if they …

Evolution of cooperation by reciprocity has been studied using two-player and n-player repeated prisoner’s dilemma … cooperation when less generous, and better at maintaining a long-term cooperation in the presence of rare defectors when more …
