Within a laboratory experiment we investigate a principal-agent game in which agents may,first, self-select into a group task (GT) or an individual task (IT) and, second, choose workeffort. In their choices of task and effort the agents have to consider pay contracts for bothtasks as offered by...

To study the effects of reminder nudges in complex environments, we apply a novel experimental approach based on a computer game in which decision makers have to pay attention to and perform multiple actions within a short period of time. The set-up allows us, first, to test the effect of...

Women and men may differ in their propensity to choose a risky outcome because of innate preferences or because their innate preferences are modified by pressure to conform to gender-stereotypes. Single-sex environments are likely to modify students' risk-taking preferences in economically...

Economists long considered money illusion to be largely irrelevant. Here we show, however, that money illusion has powerful effects on equilibrium selection. If we represent payoffs in nominal terms, choices converge to the Pareto inefficient equilibrium; however, if we lift the veil of money by...

We experimentally analyze whether the opportunity to receive a permanent contract motivates temporary group members in a public good setting and how this affects the other group members. We compare an exogenous and an endogenous decision mechanism to extend the temporary agent's group...

In an unique lab-in-the-field experiment we design a novel labor market environment, the Game of Prejudice, to elicit preferences for discrimination towards the largest minority group in Europe (the Roma) at the intensive margins as well as at the extensive margins. Our unique experiment design...

Using administrative data from a large 4-year public university, we show that male students are 18.6 percent more likely than female students to receive favorable grade changes. These gender differences cannot be explained by observable characteristics of the students, instructors, and the...

Hierarchies in social identities have been found to be integrally related to divergences in economic status. In India, caste is one such significant social identity where continued discriminatory practices towards the lower castes have resulted in poor outcomes for them. While there is...

In this paper we investigate whether the framing of the incentives used to foster participation into contexts characterized by high degrees of time pressure affects individuals' self-selection. At this aim we run a lab-in-the-field experiment structured in two parts. The first part investigates...

We study whether providing information about immigrants affects people's attitude towards them. First, we use a large representative cross-country experiment to show that, when people are told the share of immigrants in their country, they become less likely to state that there are too many of...
