Risk attitudes are known to be sensitive to large stake variations. However, little is known on the sensitivity to moderate variations in stakes. This is important for studies that want to compare risk attitudes between countries or over time. I find that variations of ±20% affect only utility,...

We let subjects take risky decisions that affect themselves and a passive recipient. Adding a requirement to justify their choices significantly reduces loss aversion. This indicates that such an accountability mechanism may be effective at debiasing loss aversion in agency relations.

We report between-subject results on the effect of monetary stakes on risk attitudes. While we find the typical risk seeking for small probabilities, risk seeking is reduced under high stakes. This suggests that utility is not consistently concave.

This paper examines how a religious festival (Ramadan) and the degree of religiosity affect cooperation and costly punishment in a public goods experiment. We find significantly higher cooperation levels outside the festival among less religious people. This behavior is consistent with a...

We add a gift in appreciation of the subject’s contribution to a social reference treatment successfully proven to trigger higher donations, and find that the share of people contributing decreases significantly, thereby eroding the original treatment’s capacity to increase donations.

The effects of stake size on cooperation and punishment are investigated using a public goods experiment. We find that an increase in stake size does neither significantly affect cooperation nor the level of punishment.

In an experiment, we study risk-taking of cohabitating student couples, finding that couples’ decisions are closer to risk-neutrality than single partners’ decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.

We studied whether relative income has an impact on subjective well-being among extremely poor people. Contrary to the findings in developed countries, we cannot reject the hypothesis that relative income has no impact on subjective well-being in rural areas of northern Ethiopia.

We examine social preferences of Swedish and Austrian children and adolescents using the experimental design of Charness and Rabin (2002). We find that difference aversion decreases while social-welfare preferences increase with age.
