This study analyzes a continuous-time N-agent Brownian hidden-action model with exponential utilities, in which agents' actions jointly determine the mean and the variance of the outcome process. In order to give a theoretical justi¯cation for the use of linear contracts, as in Holmstrom and...

This paper examines the influence of type-dependent reservation utility on the optimality of linear contracts in a Principal-Agent model of procurement. Type-dependency of reservation utility, combined with the requirements of individual rationality and incentive compatibility in the principal's...

We study contracting when both principal and agent have to exert noncontractible effort for production to take place. An analyst is uncertain about what actions are available and evaluates a contract by the expected payoffs it guarantees to each party in spite of the surrounding uncertainty....

Using the concept of Inequity Aversion we derive in a Moral Hazard setting several results which differ from conventional contract theory. Our three key insights are: First, inequity aversion plays a crucial role in the design of optimal contracts. Second, there is a strong tendency towards...

 The objective of this paper is to develop an optimal incentive system for multitaskingscientists in universities or professors under repeat contracting. With the aid of a principalagentmodel under repeat contracting, we show that (i) when a second task is assigned to aprofessor and the two...
