In this paper we analyze the frequently observed phenomenon that (i) some members of a team ('black sheep') exhibit behavior disliked by other (honest) team members, who (ii) nevertheless refrain from reporting such misbehavior to the authorities (they set up a 'wall of silence'). Much cited...

Whistle-blowing by employees plays a major role in uncovering corporate fraud. Various recent laws aim at improving protection of whistle-blowers and enhancing their willingness to report. Evidence on the effectiveness of such legislation is, however, scarce. Moreover, critics have raised...

Extending the die rolling experiment of Fischbacher and Föllmi-Heusi (2013), we compare gender effects with respect to unethical behavior by individuals and by two-person groups. In contrast to individual decisions, gender matters strongly under group decisions. We find more lying in male...

In corporate practice, incentive schemes are often complicated even for simple tasks. Hence, the way they are communicated might matter. In a controlled field experiment, we study a minimally invasive change in the communication of a well-established incentive scheme - a reminder regarding the...

We characterize optimal incentive contracts in a moral hazard framework extended in two directions. First, after effort provision, the agent is free to leave and pursue some ex-post outside option. Second, the value of this outside option is increasing in effort, and hence endogenous. Optimal...

We study management practices and performance of public sector organizations in Germany. For a representative sample of municipalities, we provide survey evidence for substantial het-erogeneity in the use of structured management practices. This heterogeneity is not driven by differences across...
