We analyze competition between workers in a gift-exchange experiment where two workers are hired by the same employer. In the competition treatment the two employees simultaneously choose their effort whereas in the baseline treatment competition cannot occur since there is only one employee per...

In this paper, we discuss learning behavior and the heterogeneity of subjects' ability to perform in real-effort tasks. Afterwards, we present a novel variant of Erkal et al.'s (2011) encryption real-effort task which aims to minimize learning behavior in repeated settings. In the task,...

This paper studies motivational crowding-out effects after financial incentives are lowered. In a real-effort setting, workers receive a piece rate before financial incentives are substituted by a one-time payment. Under the fixed payment, effort is significantly lower only when preceded by...

This paper theoretically and experimentally studies decision-making in risky and social environments. We explore the interdependence of individual risk attitudes and inequality aversion as two decisive behavioral determinants in such contexts. Our model and the data demonstrate that individual...

In this paper we study the impact of betrayal aversion on agents' effort provision, when principals have discretion regarding agents' remuneration. We show theoretically that agents who work under a nonbinding bonus contract face a trade off in their effort choice between the likelihood and the...

In a within-subjects experiment we test the relation of risk preferences and charitable giving. Women not only give substantially more than men, but also show an economically significant positive correlation between risk tolerance and donation levels. We find no such correlation for men. Men and...

This paper analyzes seasonal effects and their potential drivers in charitable giving. We analyze whether donations differ between the pre-Christmas shopping season and summer. Our experiment aims to minimize confounding factors and controls for donor heterogeneity. We find that prosocial...

This paper tests motivational crowding out in the domain of charitable giving. A novelty is that our experiment isolates alternative explanations for the decline of giving such as strategic considerations of decision makers. Moreover, preference elicitation allows us to focus on the reaction of...

This paper experimentally tests the relation between subjects' competitiveness and bargaining behavior. Bargaining is investigated in a demand-ultimatum game, where the responder can request a share of the pie from the proposer. The results show that highly competitive proposers earn less, since...

We test in a survey the impact of economic preferences on compliance and perception during the Corona pandemic. Results show that economic preferences crucially impact citizens' compliance to policies fighting the crisis. Risk tolerance negatively a↵ects citizens' avoidance of crowds, whereas...
