Building trust is very important because fraud has been on rise in online electronic markets. Trust allows participant in online electronic markets to overcome perceptions of risk and uncertainty and make a deal. This paper proposes a design of a mechanism of building trust in online electronic markets. The interesting aspects of this mechanism is that it not only improves reputation rating mea...

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...

In the play Peter Pan, the fairy Tinker Bell is about to fade away and die because nobody believes in her any more, but is saved by the belief of the audience. This is a very old meme; the gods in Ancient Greece became less or more powerful depending on how many mortals sacrificed to them. On the face of it, this seems a democratic model of trust; it follows social consensus and crumbles when t...

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 ...

This paper investigates the concept of corporate reputation and corporate image. Corporate image is the product of the experiences of a product or service and the messages sent by an organisation, while corporate reputation is the product of management behaviours and organisation-public relationships. This paper explores whether corporate reputation can be managed and who manages it. It is espe...
