Individuals faced by a tournament can oftentimes not only choose their effort level, but also the risk level of their strategy. There are some theoretical contributions on risk taking in tournaments, which mainly point out disadvantages with respect to exerted effort. Empirical evidence is rare....

The benefits and costs of different forms of job design have been analyzed in the literature yet. The focus has thereby mostly been on job designs under formal contracts between the parties. However, in the real world relational contracts - informal agreements sustained by the value of future...

In this paper, we consider the market for video games, where some firms are active in both, the market for video games hardware and software. It is puzzling that hardware can be easily made compatible with duplicated (i.e. pirated) software. We ask, whether there exist strategic reasons...

In this paper, the market for video games is considered, where some firms produce both, hardware and software. It is analyzed, whether these firms are interested in strategically enabling software piracy. It will be shown that this is indeed the case, if firms differ substantially in hardware...

We consider antitrust enforcement within the adversarial model used by the United States. We show that, under the adversarial system, the Antitrust Authority may try to prohibit mergers also in those cases in which litigation is ine? cient. Even if market concentration and technological...

We consider a double-sided moral hazard problem where each party can renege on the signed contract since there does not exist any verifi- able performance signal. It is shown that ex-post litigation can restore incentives of the agent. Moreover, when the litigation can be settled by the parties...

We develop a general framework to study contests, containing the well-known models of Tullock (1980) and Lazear and Rosen (1981) as special cases. The contest outcome depends on players' effort and skill, the latter being subject to symmetric uncertainty. The model is tractable, because a...

This paper studies sabotage in a dynamic tournament. Three players compete in two rounds. In the final round, a player who is leading in the race, but not yet beyond the reach of his competitors, gets sabotaged more heavily. As a consequence, if players are at the same position initially, they...
