We use skin conductance responses and self-reports of hedonic valence to study the emotional basis of cooperation and punishment in a social dilemma. Emotional reaction to free-riding incites individuals to apply sanctions when they are available. The application of sanctions activates a...

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...

Experimental studies of social dilemmas have shown that while the existence of a sanctioning institution improves cooperation within groups, it also has a detrimental impact on group earnings in the short run. Could the introduction of pre-play threats to punish have enough of a beneficial...

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...

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...

In this paper, we investigate individuals' investment in status in an environment where no monetary return can possibly be derived from reaching a better relative position. We use a real-effort experiment in which we permit individuals to learn and potentially improve their status (rank). We...

The authors test the hypothesis that individual effort on the job depends both on one’s own income and on the individual’s position in the relevant income distribution. Combining experimental evidence from a gift-exchange game with multi-country ISSP survey data, they analyze the extent to...

In this paper, we examine labor market favoritism in a unique laboratory experiment design that can shed light on both the private benefits and spillover costs of employer favoritism (or discrimination). Group identity is induced on subjects such that each laboratory "society"consists of eight...
