Studies have shown that there are differences in cooperative behavior across countries. Furthermore, differences in the use and the reaction on the introduction of a norm enforcement mechanism have been documented in cross-cultural studies, recently. We present data which prove that stark...

We investigate attitudes toward positionality among rural farmers in Northern Ethiopia using a survey experiment. On average, we find very low positional concerns both for income per se and for income from aid projects. The results support the claim that positional concerns are positively...

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.

Using a natural field experiment in a recreational site, a public good almost fully dependent on voluntary donations, we explored the crowding-out effect of gift rewards. First, we investigated whether receiving a map in appreciation of a donation crowded out prosocial behavior and found no...

Earlier research has shown that using a default option has a decisive effect on individuals’ choices. In many cases, however, the low proportion of subjects who switch from the pre-set default option might partly explained by inexperience with the goods or services offered, and high...

In a natural field experiment, we tested whether being alone or in a group had an effect on prosocial behavior as expressed in donations to a recreational park. We also explored whether the presence of people exogenous to the group at the time of the donation had any behavioral effect. Our first...

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a large-scale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, one-shot allocation tasks, allowing us...

This paper analyses whether individuals are influenced by the day of the week when reporting subjective well-being. By using a large panel data set and controlling for observed and unobserved individual characteristics, we find a large day-of the-week effect. Overall, we find a 'blue' Sunday...

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.
