Abstract

Studies show that reputation systems have the potential to improve market quality. In this paper we report the results of simulating a market of trading agents that uses the beta reputation system for collecting feedback and computing agents' reputations. The simulation confirms the hypothesis that the presence of the reputation system improves the quality of the market. Among other things it also shows that a market with limited duration rather than infinite longevity of transaction feedback provides the best conditions under which agents can adapt to each others change in behaviour.
