连续时间均值-方差-效用投资组合问题及其均衡策略

Continuous time mean-variance-utility portfolio problem and its equilibrium strategy

Ben-Zhang Yang, Xin-Jiang He, Song-Ping Zhu

摘要:

在本文中,我们提出了一类新的优化问题,最大化的终端财富和累积消费效用服从一个均值方差准则控制的最终风险的投资组合。通过引入投资者总体“幸福”的概念,将多目标优化问题转化为单目标优化问题,并在博弈论框架下求解。我们已经设法保持分析的易处理性,一组特殊的效用函数的封闭形式的解决方案,使我们能够讨论一些有趣的最优投资策略,还没有被发现在文献中。

英文摘要:

In this paper, we propose a new class of optimization problems, which maximize the terminal wealth and accumulated consumption utility subject to a mean variance criterion controlling the final risk of the portfolio. The multiple-objective optimization problem is firstly transformed into a single-objective one by introducing the concept of overall "happiness" of an investor defined as the aggregation of the terminal wealth under the mean-variance criterion and the expected accumulated utility, and then solved under a game theoretic framework. We have managed to maintain analytical tractability; the closed-form solutions found for a set of special utility functions enable us to discuss some interesting optimal investment strategies that have not been revealed before in literature.
