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...

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 contexts such as education and sports, skill-accumulation of individuals over time crucially depends on the amount of training they receive, which is often allocated on the basis of repeated selection. We analyze optimal selection policies in a model of endogenous skill formation where, apart...

This paper shows that monitoring too much a partner in the initial phase of a relationship may not be optimal if the goal is to determine his loyalty to the match and if the cost of ending the relationship increases over time. The intuition is simple: by monitoring too much we learn less on how...

We perform a theoretical and empirical analysis of the impact of transfer fee regulations on professional soccer in Europe. Based on a model on the interaction of moral hazard and heterogeneity, we show (i) how the regulations effect contract durations and wages, (ii) that contracting parties...

We analyze the impact of three different transfer fee systems on payoffs, contract lengths, training and effort incentives in European football. The different regimes, being used until 1995 ("Pre-Bosman" or P), currently in use ("Bosman" or B), and recently approved ("Monti" or M) differ with...

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...

When a key responsibility of a manager is to allocate more or less attractive tasks to subordinates, these subordinates have an incentive to work hard and demonstrate their talents. As a new manager is less well acquainted with these talents this incentive mechanism is reinvigorated after a...

We analyze the role of damage clauses in labor contracts using a model in which a worker may want to terminate his current employment relationship and work for another firm. We show that the initial parties to a contract have an incentive to stipulate excessive damage clauses, which leads to ex...

Recent theoretical research has identified many ways how contracts can be used as rent seeking devices vis-à-vis third parties, but there is no empirical evidence on this issue so far. To test some basic qualitative properties of this literature, we develop a theoretical and empirical framework...
