In a contest players compete for winning a prize by effort and thereby increasing their probability of winning. Contestants, however, could also improve their own relative position by harming the other players. We experimentally analyze contests with heterogeneous agents who may individually...

We analyze explicit and implicit contracts in a repeated principal-agent model with observable but only partially contractible actions of the agent. It is shown that the set of implementable actions may increase or decrease if additional actions become contractible.

We reconsider Tirole's framework of a three-tier principal-agent problem, in which he has shown that an incentive problem is caused by the possibility of monetary side payments between the agent and the middle -level supervisor. We consider the case where monetary transfers are not possible, but...

The effects of unproductive lobbying have so far mainly been addressed by the public choice literature on rent-seeking and by Milgrom/Roberts' (1988,1990) work on influence activities in organizations. Our paper makes an attempt to incorporate lobbying into the simple principal-agent framework...

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...

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...

Several empirical studies have challenged tournament theory by pointing out that (1) there is considerable pay variation within hierarchy levels, (2) promotion premiums only in part explain hierarchical wage differences and (3) external recruitment is observable on nearly any hierarchy level. We...

The importance of fair and equal treatment of workers is at the heart of the debate in organizational management. In this regard, we study how reward mechanisms and production technologies affect effort provision in teams. Our experimental results demonstrate that unequal rewards can potentially...

The existing literature on the comparison of tournaments and piece rates as alternative incentive schemes has focused on the case of unlimited liability. However, in practice real workers' wealth is typically restricted. Therefore, this paper compares both schemes under the assumption of limited...

This paper discusses the properties of stylized U.S. ("U-type") and Japanese tournaments ("J-type"), which can both solve the unverifiability problem of labor contracts. Under a zero-profit condition, both tournament types will yield first-best efforts if workers are homogenous and risk neutral....
