Experimental research on generosity has focused predominantly on behavior in the monetary domain, although many real life decisions take place in the non-monetary domain. Investigating generosity preferences in the non-monetary domain is important to understand a large class of situations...

During the COVID-19 pandemic, the introduction of mandatory face mask usage was accompanied by a heated debate. It was argued that community use of masks creates a false sense of security that could decrease social distancing, thus making matters worse. We conducted a randomized field experiment...

Integrating economic experiments into household surveys provides unique possibilities. We introduce the German Socio-Economic Panel's Innovation Sample (SOEPIS), which offers researchers detailed panel data and the possibility to collect personalized experimental and survey data for free. We...

Many occupations and industries are highly segregated with respect to gender. This segregation could be due to perceived job-specific productivity differences between men and women. It could also result from the belief that single-gender teams perform better. We investigate the two explanations...

Bosch-Domènech et al. (2014) reported a negative association between 2D:4D, a suggested marker of prenatal testosterone exposure, and the Cognitive Reflection Test (CRT) in a sample of 623 university students. In this pre-registered study, we test whether we can replicate their findings in a...

We investigate the elasticity of moral ignorance with respect to monetary incentives and social norm information. We propose that individuals suffer from higher moral costs when rejecting a certain donation, and thus pay for moral ignorance. Consistent with our model, we find significant...

We explore situations in which a decision-maker bears responsibility for somebody else's outcomes as well as for her own. For gains we confirm the intuition that being responsible for somebody else's payoffs increases risk aversion, while in the loss domain we find increased risk seeking. In a...

Is there a way of matching donations that avoids crowding out? We introduce a novel matching method where the matched amount is allocated to a different project, present some simple theoretical considerations that predict reduced crowding out or more crowding in (depending on the degree of...

Multiple sources of funding are becoming increasingly important for charitable organizations. Donations from corporate donors for example account for 25-35% of charitable income for the largest US charities, across charitable sectors. This note presents some tentative first evidence from a...

Altruists and envious people who meet in contests are symbionts. They do better than a population of narrowly rational individuals. If there are only altruists and envious individuals, a particular mixture of altruists and envious individuals is evolutionarily stable.
