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...

We devise an experiment to explore the effect of different degrees of bargaining power on the design and the selection of contracts in a hidden-information context. In our benchmark case, each principal is matched with one agent of unknown type. In our second treatment, a principal can select...

Are women disproportionately attracted to work environments where cooperation rather than competition is rewarded? This paper reports the results of a real-effort experiment in which participants choose between an individual compensation scheme and a team-based payment scheme. We find that women...

This paper presents the results of a laboratory experiment in which workers perform a real-effort task and supervisors report the workers' performance to the experimenter. The report is non verifiable and determines the earnings of both the supervisor and the worker. We find that not all the...

This paper experimentally investigates if and how people's competitiveness depends on their own gender and on the gender of people with whom they interact. Participants are given information about the gender of the co-participant they are matched with, they then choose between a tournament or a...

In social dilemmas, leading a team by making heroic efforts may prove costly, especially when the followers are not adequately motivated to make similar sacrifices. Attempting to shed light on what drives people to lead, we devise a two-stage public good experiment with endogenous timing. We...

We study the influence of risk and time preferences on trust and trustworthiness by conducting a field experiment in Vietnamese villages and by estimating the parameters of the Cumulative Prospect Theory and of quasi-hyperbolic time preferences. We find that while probability sensitivity or risk...

How does leadership work in teams? In this paper, leadership is grounded on both the possession of a private information by the leader and by her ability to communicate credibly with followers in order to induce them to expand high efforts. This paper reports an experiment testing the efficiency...

Lorsque le financement d'un bien collectif repose sur des contributions volontaires, il est courant d'observer une offre insuffisante du bien collectif en raison d'un comportement de passager clandestin. Pour faire face àun déficit d''offre de bien collectif, la puissance publique intervient...

This paper reports the results of an experiment on how team composition influences both the contract offer of employers and employee performance when a revenue-sharing scheme is introduced. Experimental evidence shows that the principal ceases trying to monitor her team through a contract offer...
