In this paper we analyze the behavioral consequences of transparent wage distributions on workers' motivation. We study a simple gift-exchange game with one principal and three agents in two different treatments. In the first treatment, agents are not informed about their co-workers' wages and...

We experimentally test Dufwenberg and Kirchsteiger's (2004) theory of sequential reciprocity in a sequential prisoner's dilemma (SPD) and a mini-ultimatum game (MUG). Data on behavior and first- and second-order beliefs allow us to classify each subject's behavior as a material best response, a...

We study the interplay of inequality and trust in a dynamic game, in which trust increases efficiency and thus allows higher growth of the experimental economy in the future. We find that trust is initially high in a treatment starting with equal endowments, but decreases over time. In a...

In reciprocal interactions, both genuine kindness and self-interested material gain may motivate socially beneficial actions. The paper presents results from two experiments that distinguish the role of perceived motives in reciprocal decision making from the role of outcomes or perceived...

This paper investigates gender differences in donating behavior in double-anonymous dictator game experiments. To do so, we developed a new treatment where researchers can connect the gender of a dictator to her/his donation amount despite both female and male dictators being gathered in a room...

We study the role of performance differences in a task requiring cognitive effort on in-group bias. We show that the in-group bias is strong in groups consisting of high-performing members, and it is weak in low-performing groups. This holds although high-performing subjects exhibit no in-group...
