indirect reciprocity in the context of the evolution of cooperation, basic models of social dilemma situations, the path taken … in the elaboration of mathematical analysis using evolutionary game theory, the discovery of image scoring norms, and the …

interaction impacts cooperation within groups and surplus distribution. We developed and tested experimentally a Surplus … Allocation Game where cooperation of four agents is needed to produce surplus, but only two have the power to allocate it among … distributors and receivers. While behavior at the group level is diverse for surplus allocation and amount of cooperation …

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 …

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 …

Human cooperation, occurring without reciprocation and between unrelated individuals in large populations, represents … evidence for lower cooperation (i) when exposed to social information about peer cooperation levels than without such … observed cooperation was more likely to be caused by participants' general propensity to cooperate than by the effect of social …
