Cooperation models, such as ERC and inequality aversion, yield superior predictions compared to the standard … account well for the observed fairness and cooperation in all the tested games. The impressive predictions of the theory … promoting fairness and cooperation in the discussed games is only marginal. Strikingly, the Golden Ratio, known for its …

Cooperation in social dilemmas plays a pivotal role in the formation of systems at all levels of complexity, from … stability of cooperation pose an evolutionary conundrum, since cooperation, though beneficial to others, is costly to the … of cooperation without bearing the costs of cooperating themselves. Many proximate mechanisms have been proposed to …

low probability of survival. We derive a rule for the evolutionary stability of cooperation, x/z > T/R, where x represents … the duration of mutual cooperation, z the duration of exploitation, T the defector’s free-riding payoff, and R the payoff … for mutual cooperation. This finding suggests that higher survival costs can enhance social welfare by selecting for …

Cooperation is widely recognized to be fundamental for the well-balanced development of human societies. Several … different approaches have been proposed to explain the emergence of cooperation in populations of individuals playing the … cooperation for these classes of games. We find the conditions for which these Nash equilibria are asymptotically stable, and we …

Indirect reciprocity is one of the major mechanisms driving the evolution of cooperation in human societies. There are … two types of indirect reciprocity: upstream and downstream reciprocity. Cooperation in downstream reciprocity follows the … pattern ‘You helped someone, and I will help you’, while the direction of cooperation is reversed in upstream reciprocity …
