We study the determinants of the (steady-state) POUM effect in a model where the individuals evaluate their expected future income using both their current income and observable characteristics such as education, race or gender.

The issue of how to best elicit charitable contributions has long been an important one for charitable organizations. Some recent studies have examined different schemes for eliciting contributions for public radio and maximizing revenue for commercial purposes. Our study is a pure field...

Is truth-value of a statement what lying aversion is all about? We propose an experimental test and find only limited support. In this context with 'bare promises', we also test for guilt aversion and again find only limited support.

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.

We study the effects of voluntary leadership in experimental public goods games when each group member can volunteer to contribute before the other members. We find that voluntary leadership increases contributions significantly, compared to a treatment where leadership is enforced exogenously.

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.

Arad and Rubinstein (2012a) have designed a novel game to study level-k reasoning experimentally. Just like them, we find that the depth of reasoning is very limited and clearly different from that in equilibrium play. We show that such behavior is even robust to repetitions; hence there is, at...

We examine gender differences in trust in another party's cooperation (CC) or its ability (AC). While men and women do not differ concerning trust in cooperation, gender has a strong influence when trust in another subject's ability is required.
