Despite recent advances in reputation technologies, it is not clear how reputation systems can affect human cooperation in social networks. Although it is known that two of the major mechanisms in the evolution of cooperation are spatial selection and reputation-based reciprocity, theoretical study of the interplay between both mechanisms remains almost uncharted. Here, we present a new individual-based model for the evolution of reciprocal cooperation between reputation and networks. We… 

The evolution of cooperation based on indirect reciprocity and spatial locality in continuous space

An agent-based model in a two-dimensional continuous space where not only the game-based interaction but also the transmission of agents’ reputation take place based on the spatial locality is considered, finding that if the movement duration is long enough, a higher cooperation rate could be promoted.

Exploring norms indispensable for both emergence and maintenance of cooperation in indirect reciprocity

Some indispensable norms for emergence and sustenance of cooperation are shown using a norm knockout method which has been developed to analyze a function of each norm in the environment of coexistence of many norms.

Effect of memory, intolerance, and second-order reputation on cooperation.

This work relies on previous experimental findings to build a theoretical model based on two cooperation driving mechanisms: second-order reputation and memory, and finds that, when considering memory, the stern judging rule shows the lowest values of cooperation, while stricter rules show higher cooperation levels.

Clustering Drives Cooperation on Reputation Networks, All Else Fixed

This paper demonstrates the underlying mechanism in a way that is accessible to scientists not specialising in networks and shows that, when the size and degree of the network is fixed, it is the clustering coefficient that drives differences in how cooperative social networks are.

Experimental evidence of selective inattention in reputation-based cooperation

It is demonstrated that subjects’ decision-making in relation to cooperative action depends on the content of the information they receive about their recipients, and this supports the proposition that selective inattention occurs in reputation-based cooperation.

Promotion of Robust Cooperation Among Agents in Complex Networks by Enhanced Expectation-of-Cooperation Strategy

Experiments demonstrated that agents using the enhanced expectation-of-cooperation strategy can effectively distinguish cooperative neighboring agents from all-defecting agents and thus can spread cooperation among EEoC agents and avoid being exploited by AllD agents.

A Theoretical Approach to Norm Ecosystems: Two Adaptive Architectures of Indirect Reciprocity Show Different Paths to the Evolution of Cooperation

Impacts of different adaptive architectures, i.e., ways for individuals to adapt to environments, on indirect reciprocity are investigated and an analytic method is proposed to study norm ecosystems in which all possible second order social norms potentially exist and compete.

A Review of Theoretical Studies on Indirect Reciprocity

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 breakthroughs brought about by the analysis of the evolutionary instability of the norms are introduced.

The effects of reputational and social knowledge on cooperation

It is shown that global reputational knowledge is crucial to sustaining a high level of cooperation and welfare, associated with the emergence of dense and clustered networks with highly cooperative hubs.

Reputation-based partner choice promotes cooperation in social networks.

The results highlight the importance of the consideration of reputation (indirect reciprocity) on the promotion of cooperation when individuals can adjust their partnerships when individuals are able to alter their behavioral strategies and their social interaction partnerships on the basis of reputation.

Inferring Reputation Promotes the Evolution of Cooperation in Spatial Social Dilemma Games

The mechanism of inferring reputation into the selection of potential strategy sources to explore the evolution of cooperation is introduced and it is shown that the moderate value of evaluation factor enables cooperation to thrive best.

Cooperation Survives and Cheating Pays in a Dynamic Network Structure with Unreliable Reputation

An experiment based on the Prisoner's Dilemma is designed as a model for social interactions, which finds that the aggregate cooperation level is practically unchanged and two distinct types of behavior are found, one of reliable subjects and one of cheaters, where the latter artificially fake their reputation in almost every interaction.

Reputation drives cooperative behaviour and network formation in human groups

It is shown, for the first time, that reputation can be very well quantified as a weighted mean of the fractions of past cooperative acts and the last action performed, which has potential applications in collaborative systems and e-commerce.

THE EVOLUTION OF GENERALIZED RECIPROCITY ON SOCIAL INTERACTION NETWORKS

This work investigates whether social network structure can mitigate the vulnerability of reciprocal altruism in animals that hardly ever interact randomly and shows that heterogeneous interaction patterns strongly support the evolution of generalized reciprocity.

Evolution of Cooperation Driven by Reputation-Based Migration

A reputation-based model is proposed to explore the effect of migration on cooperation in the contest of the prisoner's dilemma and shows that cooperation is promoted for relatively large population density and not very large temptation to defect.

Indirect reciprocity is sensitive to costs of information transfer

It is shown that natural selection never favors indirect reciprocal cooperation in the presence of the cost of reputation building, regardless of thecost-to-benefit ratio of cooperation or moral assessment rules (social norms).
