The impact of transparency on the extent of reciprocal behavior is investigated in a simple repeated gift exchange experiment, where principals set wages and agents respond by choosing effort levels. In addition to the efforts the principals' payoffs are determined by a random component. It is...

The costs of vertical integration are analyzed within a game-theoretic signaling model. It is shown that a company when being vertically integrated with a supplier may well decide to buy certain components from this supplier even at a lower quality than that offered by external sources. When the...

By enriching a principal-agent model it is shown that the introduction of monetary incentives may reduce an agent's motivation. In a first step, we allow for the possibility that some agents stick to unverifiable agreements. The larger the fraction of reliable agents, the lower powered will then...

A central question in designing optimal policies concerns the assignment of individuals with different observable characteristics to different treatments. We study this question in the context of increasing workers' performance by using targeted incentives based on measurable worker...

We compare evaluations of employee performance by individuals and groups of supervisors, analyzing a formal model and running a laboratory experiment. The model predicts that multi-rater evaluations are more precise than single-rater evaluations if groups rationally aggregate their signals about...

We investigate how to strategically motivate sales agents in intermediary markets. In collaboration with a large travel company, we run a field experiment with more than 1, 200 independently owned intermediaries that sell our study firm's own products as well as products from competitors to end...

We present a natural field experiment on promoting pay equity through simple modifications to the salary review process involving 623 middle managers and 8,951 subordinate employees of a large technology firm. We first document a gender gap not only in salary levels but also in salary increases....

We study the impact of managers on the success of professional soccer teams using data from the German "Bundesliga". We evaluate the performance impact of individual managers by estimating regression models that include both team and manager fixed effects, where we are exploiting the high...
