This paper estimates peer effects originating from the ability composition of tutorial groups for undergraduate students in economics. We manipulated the composition of groups to achieve a wide range of support, and assigned students - conditional on their ability - randomly. The data support a...

How do peers influence the impact of incentives? Despite much work on incentives, little is known about the spillover effects of incentives. We investigate two mechanisms by which these effects can occur: through peers' actions and peers' incentives. In a field experiment on snack choice (grapes...

Little is known about how peers influence the impact of incentives. We investigate two mechanisms by which these effects can occur: through peers' actions and peers' incentives. In a field experiment on snack choice in the school lunchroom (choice of grapes versus cookies), we randomize who...

This paper presents the result of a field experiment on the effectiveness of non-monetary incentives on pupils' achievement on a mathematical multiple choice test. Our sample consists of 2113 pupils of deprived and high-achieving secondary schools in Germany. Based on a pre-study, we compare the...

Dishonest activities with negative consequences for others and society are often undertaken by individuals as well as groups of people. In this paper, we use a field experiment among students aged 11-16 years to study whether there is a difference between individual and group cheating behavior....

We conduct a field experiment in a Dutch retail chain of 122 stores to study the interaction between team incentives, team social cohesion, and team performance. Theory predicts that the effect of team incentives on team performance increases with the team's social cohesion, because social...

In many natural environments, carefully chosen peers influence individual behavior. In this paper, we examine how self-selected peers affect performance in contrast to randomly assigned ones. We conduct a field experiment in physical education classes at secondary schools. Students participate...

We explore the role of self- and peer evaluations in education, with a particular emphasis on gender differences. We construct a model of (self-)deception to predict outcomes for scenarios with and without self-evaluation. By using unique data from a first-year economics class at a Sino-UK...
