In contrast to previous studies on cross-group comparisons of conditional cooperation, this study keeps cross- and within-country dimensions constant. The results reveal significantly different cooperation behavior between social groups in the same location.<p>

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 develop a model that relates self-control and conflict identification to cooperation patterns in social dilemmas. As predicted, we find in a laboratory public goods experiment a robust association between stronger self-control and higher levels of cooperation. This means that there is...

This paper investigates whether disclosure crowds out pro-social behavior using a public goods experiment. In a between-subject design, we investigate different degrees of disclosure. We find a small positive but insignificant effect of disclosure treatments on contributions to the public good....

When facing the opportunity to allocate resources between oneself and others, individuals may experience a self-control conflict between urges to act selfishly and preferences to act pro-socially. We explore the domain of conditional cooperation, and we test the hypothesis that increased...

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...

Many economic decisions are made jointly within households. This raises the question about spouses’ relative influence on joint decisions and the determinants of relative influence. Using a controlled experiment (on inter-temporal choice), we let each spouse first make individual decisions and...

We conducted a field experiment in a protected area to explore the effects of conformity to a social reference versus a comparable, but imposed, suggested donation. As observed before, we see visitors conforming to the changing social reference. On the other hand, the treatment in which we...

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 mechansism have been documented in cross-cultural studies, recently. We present data which prove that stark...

Using a random sample of individuals in rural Bangladesh, this paper investigates people’s preferences regarding relative values of lives when it comes to different ages of the individuals being saved. By assuming that an individual has preferences concerning different states of the world, and...
