Hotelling’s famous ‘Principle of Minimum Differentiation’ suggests that two firms engaging in spatial competition will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not differentiated and...

In practice, two types of tournaments can be distinguished - U-type and J-type tournaments. In U-type tournaments, workers receive prizes that have been fixed in advance. In J-type tournaments, the employer fixes an aggregate wage bill in advance, which is then shared among the workers according...

This paper extends the standard principal-agent model with moral hazard to allow for agents having reference-dependent preferences according to Köszegi and Rabin (2006, 2007). The main finding is that loss aversion leads to fairly simple contracts. In particular, when shifting the focus from...

In this paper, we combine the strategic delegation approach of Fershtman-Judd-Sklivas with contets. The results show that besides a symmetric equilibrium there also exist asymmetric equilibria in which one owner induces pure sales maximization to his manager so that all the other firms drop out...

We study an industry in which an upstream monopolist supplies an essential input at a regulated price to several downstream firms. Legal unbundling means that a downstream firm owns the upstream firm but this upstream firm is legally independent and maximizes its own upstream profits. We allow...

It is often claimed that (i) managers work too hard on operational issues and do not spend enough effort on strategic activities and (ii) something can be done about this by introducing nonfinancial performance measures as for instance with a balanced scorecard. We give an explanation for both...

In an asymmetric tournament model with endogenous risk choice by the agents it is shown that equilibrium efforts decrease (increase) with risk if abilities are sufficiently similar (different). Risk also affects winning probabilities. The interaction of both effects is analyzed.

This paper considers the interplay of job assignments with the intrinsic and extrinsic motivation of an agent. Job assignments influence the self confidence of the agent, and thereby his intrinsic motivation. Monetary reward allow the principal to complement intrinsic motivation with extrinsic...

In innovation contests, the progress of the competing firms in the innovation process is usually their private information. We analyze an innovation contest in which research firms have a stochastic technology to develop innovations at a fixed cost, but their progress is publicly announced. We...
