英文摘要:
In this paper, we consider a problem of contract theory in which several Principals hire a common Agent and we study the model in the continuous time setting. We show that optimal contracts should satisfy some equilibrium conditions and we reduce the optimisation problem of the Principals to a system of coupled Hamilton-Jacobi-Bellman (HJB) equations. We provide conditions ensuring that for risk-neutral Principals, the system of coupled HJB equations admits a solution. Further, we apply our study in a more specific linear-quadratic model where two interacting Principals hire one common Agent. In this continuous time model, we extend the result of Bernheim and Whinston (1986) in which the authors compare the optimal effort of the Agent in a non-cooperative Principals model and that in the aggregate model, by showing that these two optimisations coincide only in the first best case. We also study the sensibility of the optimal effort and the optimal remunerations with respect to appetence parameters and the correlation between the projects.

中文摘要:
在本文中,我们考虑了一个契约理论问题,其中多个委托人雇佣一个共同的代理人,并研究了连续时间环境下的模型。我们证明了最优契约应该满足一些平衡条件,并将委托人的优化问题归结为一个耦合的Hamilton-Jacobi-Bellman(HJB)方程组。我们提供了条件,确保对于风险中性主体,耦合HJB方程组允许解。此外,我们将我们的研究应用于一个更具体的线性二次模型,其中两个相互作用的主体雇佣一个共同的代理。在这个连续时间模型中,我们扩展了Bernheim和Whinston(1986)的结果,在该结果中,作者比较了非合作委托人模型和聚合模型中代理人的最优努力,表明这两种优化仅在第一种最佳情况下重合。我们还研究了最优努力和最优报酬对偏好参数的敏感性以及项目之间的相关性。
