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...

Most studies find no collusion in tournaments. This result suggests that social preferences are irrelevant in this context. We investigate the impact of social preferences in a tournament using data from a laboratory experiment with two treatments. In a conentional tournament, an agent receives...

Mediation is a popular process to manage conflicts, but there is little systematic insight into its mechanisms. This paper discusses the results from an experiment in which a mediator can induce two conflict parties to behave cooperatively. If the mediator recommends cooperative behavior and...

In tournaments, the large variance in effort provision is incompatible with standard economic theory. In our experiment we test theoretical predictions about the role of envy and loss aversion in tournaments. Our results confirm that envy implies higher effort while loss aversion increases the...

Property rights theory suggests that vertical integration is a sensible solution to hold-up problems and therefore improves social welfare. Theories of reciprocity, in contrast, suggest that vertical integration can reduce social welfare if it implies an unfair distribution. Translating the...
