Reputation plays a central role in human societies. Empirical and theoretical work indicates that a good reputation is valuable in that it increases one's expected payoff in the future. Here, we explore a game that couples a repeated Prisoner's Dilemma (PD), in which participants can earn and can benefit from a good reputation, with a market in which reputation can be bought and sold. This game...

Generally online (Electronic commerce or E-commerce) applications use reputation reporting system for trust evaluation where they gather overall feedback ratings from the sellers to compute the reputation score. A well-known issue with the reputation conduct system is " all good reputation " problem where over 99% of feedback ratings are positive leading to high reputation scores. This issue is...

Some form of measure of reputation seems to be at the heart of all online transactional activities that require trust. However, most of the first generation reputation management systems (RMS) used are yet very basic and often vulnerable to various attacks. In this research, we take a holistic approach to the problem of RMS design. We propose a generalized set-theoretic reputation function cons...

Reputation systems evolve as a mechanism to build trust in virtual communities. In this paper we evaluate different metrics for computing reputation in multi-agent systems. We present a formal model for describing metrics in reputation systems and show how different well-known global reputation metrics are expressed by it. Based on the model a generic simulation framework for reputation metrics...

Markets for Reputation: Evidence on Quality and Quantity in Academe We develop a theory of the market for individual reputation, an indicator of regard by one’s peers and others. The central questions are: 1) Does the quantity of exposures raise reputation independent of their quality? and 2) Assuming that overall quality matters for reputation, does the quality of an individual’s most importan...

The need for reputation assessment is particularly strong in peer-to-peer (P2P) systems because the peers’ personal site autonomy is amplified by the inherent technological decentralization of the environment. However, the decentralization notion makes the problem of designing a peer-to-peer based reputation assessment substantially harder in P2P networks than in centralized settings. Existing ...

Reputation management is a powerful security tool that helps establish the trustworthiness of users in online applications. One of the most successful use of reputation systems is on e-commerce web sites such as eBay.com and Amazon.com, which use reputation systems to root out fraudulent sellers. Reputation systems can also play an important role in social networks to enforce various security r...

A positive corporate reputation is generally taken to be a valuable resource leading to competitive advantage. In this paper we examine the association between a firm's media reputation and the amount of trade credit given in a sample of listed UK firms. Consistent with expectations, our results show that a firm's willingness to extend trade credit to its customers is inversely related to its m...
