Heston模型最优投资问题的一个显式解

An explicit solution for optimal investment in Heston model

Elena Boguslavskaya, Dmitry Muravey

摘要:

在本文中,我们考虑了一个变化的Merton的问题,增加了随机波动率和有限的时间范围。在对过程和效用函数作一定的假设下,相应的最优控制问题可化为线性抛物边界问题。由此产生的抛物型偏微分方程通常很难求解,即使它是线性的。本文的贡献池的显式解决随机最优控制问题。我们的主要结果是Heston模型中最优投资的精确解。

英文摘要:

In this paper we consider a variation of the Merton's problem with added stochastic volatility and finite time horizon. It is known that the corresponding optimal control problem may be reduced to a linear parabolic boundary problem under some assumptions on the underlying process and the utility function. The resulting parabolic PDE is often quite difficult to solve, even when it is linear. The present paper contributes to the pool of explicit solutions for stochastic optimal control problems. Our main result is the exact solution for optimal investment in Heston model.
