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 …

Intensive studies on indirect reciprocity have explored rational assessment rules for maintaining cooperation and … hybrid-assessment scheme in which players use both assessment systems and by using evolutionary game theory. We calculated … replicator equations using the expected payoffs of three strategies: unconditional cooperation, unconditional defection, and …

conditionally cooperative preferences. Cooperation generated by this type of preferences is notoriously unstable, as individuals …-shared conclusion that cooperation observed in experiments (and its collapse) is mostly driven by imperfect reciprocity. In this study …

Case studies of cartels and recent theory suggest that repeated communication is key for stable cooperation in … understood. We study cooperation under different monitoring and communication structures in the laboratory. Under all monitoring … monitoring, where actions can only be observed with noise, cooperation is stable only when subjects can communicate before every …

This paper studies the interaction of beliefs, payoff parameters, and the cooperation rate in the infinitely repeated … prisoner's dilemma. We show formally that a player's belief about the probability of cooperation by their opponent moderates … the effect of changes in the payoff parameters on cooperation. If beliefs are high, increasing the gain from unilateral …
