The growth of online electronic commerce and markets is attributed not only to their ease of use but also to the fact that they provide reputation and feedback systems that help create trust. Recent research has exposed, however, that feedback systems are biased, suffer from “grade inflation”, and do not clearly differentiate between higher and lower quality sellers. This lecture highlights recent research that addresses these concerns and presents ways to increase the effectiveness of online reputation systems and markets.
