Les conséquences de la manipulation de la réputation dans les systèmes d'évaluation en ligne. Une étude expérimentale


  • Marianne Lumeau
  • David Masclet
  • Thierry Pénard


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 when it is costly, which influences the decisions of evaluation and has a negative impact on trust and trustworthiness. Classification JEL : C92, C72, L14, L86
