Microfinance is generally associated with high repayment rates. However, it is not clear whether the success of microfinance results only from the use of group lending or is also due to other mechanisms such as peer sanctioning or dynamic incentives induced by long-term relationships that are...

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...

Microfinance is generally associated with high repayment rates. However, it is not clear whether the success of microfinance results only from the use of group lending or is also due to other mechanisms such as peer sanctioning or dynamic incentives induced by long-term relationships that are...

This paper investigates experimentally gender and race discrimination in hiring decisions through a simple controlled setting where employers can observe workers’ individual characteristics before recruiting them. In this paper, we explore whether discrimination, if any, is statistical or...

We use data from the Trajectoires et Origines survey to analyze the labor-market outcomes of both second-generation immigrants and their French native counterparts. Second-generation immigrants have on average a lower probability of employment and lower wages than French natives. We find however...
