Several studies have highlighted the role of feedback mechanisms in the success of electronic marketplaces. In this current experiment, we attempt to isolate experimentally the role of reputation and social (dis)approval associated to ratings using a trust game experiment with the opportunity to...

This paper reports the results of a laboratory experiment that aims at investigating the effect of manipulating reputation in the context of online decentralized feedback systems, such as eBay. Our experimental results indicate that the agents do not hesitate to manipulate their reputation even...

Several previous studies have highlighted the role of feedback mechanisms in the success of electronic marketplaces. This paper contends that the effectiveness of online feedback mechanisms passes through two channels, namely a ‘reputational’ effect that has been largely documented in the...

Feedback systems are claimed to be a crucial component of the success of electronic marketplaces like eBay or Amazon Marketplace. This article aims to compare the effects of various feedback systems on trust between anonymous traders, through a set of experiments based on the trust game. Our...

Several online marketplaces, like eBay provide their users with reputation management mechanisms (evaluations, ratings,...). This article aims at investigating the impact of these reputation mechanisms on trust building and market efficiency, through a set of experiments based on the trust game...

In this paper we replicate and extend the experiment of Fehr and Gaechter (2000) that analyzes the effect of an opportunity to punish others on the level contributions in the Voluntary Contributions Mechanism.
