We study the evolution of cooperation in group interactions where players are randomly drawn from well … voluntary participation. We first study how prescribed stochastic opting-out affects cooperation in finite populations, and then … both genetic and behavioral evolution mechanisms. Moreover, in the model, cooperation is favored by natural selection over …

We study the coevolution of cooperation, preferences and cooperative signals in an environment where individuals engage …

We study the coevolution of cooperation, preferences, and cooperative signals in an environment where individuals … in (social norms of) cooperation in societies which are not driven by social or environmental shocks. …

The article suggests a new explanation for cooperation in large, unstructured societies that avoids the restrictions … for cooperation to be part of an asymptotically stable equilibrium of an evolutionary dynamics of signaling norm … of the social norm and two parameters measuring the cost of cooperation into relation with each other. …

cooperative behavior include assortative matching in groups, group longevity, and punishment-based group norms. …

Economists have a long tradition in identifying the evolution of cooperation in large, unstructured societies as a … puzzle. We suggest a new explanation for cooperation which avoids restrictions of most previous attempts. Our explanation … deals with the role of internalized norms for cooperation in large unstructured populations. Even internalized norms, i …
