We conduct a field experiment in a naturally occurring labor environment and track whether the performance of workers responds to unexpected wage increases. Specifically, we investigate how the timing of wage increases affects efforts. We find that workers performance is about 11% higher for the...

We investigate how bonus payments affect satisfaction and performance of managers in a large, multinational company. We find that falling behind a naturally occurring reference point for bonus comparisons reduces satisfaction and subsequent performance. The effects tend to be mitigated if...

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...

We report on two experiments designed to investigate the role of beliefs for ingroup favoritism. On average, dictators transfer substantially more to recipients who are publicly known to share the same group identity, compared to transfers given to recipients who are publicly known to be...

We let subjects estimate behavior and expectations of others before they play dictator games, and only vary the quantitative scales for their estimates. Our data show that this manipulation may significantly affect economic decisions: dictators who are presented a scale with a higher midpoint...

People do not only feel guilt from not living up to others' expectations (Battigalli and Dufwenberg (2007)), but may also like to exceed them. We propose a model that generalizes the guilt aversion model to capture the possibility of positive surprises when making gifts. A model extension allows...

We conduct an Internet dictator game experiment in collaboration with the popular German Sunday paper “Welt am Sonntag”, employing a wider and more representative subject pool than standard laboratory experiments. Recipients either knew or did not know the size of the cake distributed by the...

We study the interplay of inequality and trust in a dynamic growth game, in which trust increases efficiency and thus allows higher growth of the laboratory economy in the future. We find that trust (as measured by the percentage of wealth invested in a trust game) is initially high in a...
