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 derive a natural definition of responsibility in a formal model where employees care for their career prospects: A superior holds a subordinate responsible for a task, when she announces her beliefs that this subordinate contributes most to this task. We show, that those announced beliefs...

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...

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...

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 study the compensation of gig workers in a natural field experiment. To derive testable predictions, this paper presents a formal model capturing a central feature of online freelance work: gig work- ers' ability to choose both how much to work and how big an effort to make. We analyse the...
