In intergroup contests a manager advises and motivates her group’s members. Her rewards often depend on the subsequent contest expenditure of the members. I test whether such incentives undermine the credibility and effectiveness of a manager’s efforts. In the different experimental...

The paper presents experimental evidence on the impact of managers and their incentives on the behavior of group members in intergroup contests. I find that members follow the nonbinding investment recommendations of their group manager in particular if the managers payoff does not depend on the...

We study the effects of random assignment to coeducational and single-sex classes on the academic performance of female high school students. Our estimation results show that single-sex schooling improves the performance of female students in mathematics. This positive effect increases if the...

We analyze educational institutions incentives to set up demanding or lax curricula in duopolistic markets for education with endogenous enrolment of students. We assume that there is a positive externality of student achievement on the local economy. Comparing the case of regulated tuition fees...

A small lie appears trivial but it obviously violates moral commandments. We analyze whether the preference for others’ truth telling is absolute or depends on the size of a lie. In a laboratory experiment we compare punishment for different sizes of lies controlling for the resulting economic...

This paper uses experimental data to analyze how competitive behavior is influenced by coaching and peer observation. We study behavior in a sequential contest, considering information about the effort level of subjects in other contests (observation of peers) and information about the...

Social preferences explain competitive behavior between agents and reciprocity towards a principal but there is no insight into the interaction of competition and reciprocity. We conducted a laboratory experiment with two treatments to address this issue. In a conventional tournament, an agent...
