Indirect Reciprocity under Incomplete Observation
Indirect reciprocity, in which individuals help others with a good reputation but not those with a bad reputation, is a mechanism for cooperation in social dilemma situations when individuals do not repeatedly interact with the same partners. In a relatively large society where indirect reciprocity is relevant, individuals may not know each other's reputation even indirectly. Previous studies i...
متن کاملEvolution of gossip-based indirect reciprocity on a bipartite network
Cooperation can be supported by indirect reciprocity via reputation. Thanks to gossip, reputations are built and circulated and humans can identify defectors and ostracise them. However, the evolutionary stability of gossip is allegedly undermined by the fact that it is more error-prone that direct observation, whereas ostracism could be ineffective if the partner selection mechanism is not rob...

Indirect reciprocity (IR) occurs when individuals help those who help others. It is important as a potential explanation for why people might develop cooperative reputations. However, previous models of IR are based on the assumption that individuals never meet again. Yet humans and other animals often interact repeatedly within groups, thereby violating the fundamental basis of these models. W...

In this paper we report experimental results that relate to the reciprocity experiment of Berg, Dickhaut, and McCabe (1995). We consider direct reciprocity, which means to respond in kind to another person, and indirect reciprocity, understood as rewarding someone else. Another variation concerns the information about the multiplier of donations where we compare the benchmark case with a common...
