带违约的随机最大值原理

Stochastic Maximum Principle with Default

Khalida Bachir Cherif, Nacira Agram, Kristina Dahl

摘要:

本文给出了一类随机最优控制问题的充分必要最大值原理,其中系统状态由带缺省值的受控随机微分方程给出。证明了受控违约随机微分方程解的存在唯一性。进一步证明了伴随倒向随机微分方程解的存在唯一性,该方程是与最大值原理有关的。最后,我们应用最大值原理来解决对数效用函数的效用最大化问题。

英文摘要:

In this paper, we derive sufficient and necessary maximum principles for a stochastic optimal control problem where the system state is given by a controlled stochastic differential equation with default. We prove existence of a unique solution to the controlled default stochastic differential equation. Furthermore, we prove existence and uniqueness of solution to the adjoint backward stochastic differential equation which appears in connection to the maximum principles. Finally, we apply the maximum principles to solve a utility maximisation problem with logarithmic utility functions.
