均值-方差-偏度投资组合问题的鲁棒均衡策略

Robust equilibrium strategy for mean-variance-skewness portfolio selection problem

Jian-hao Kang, Nan-jing Huang, Zhihao Hu, Ben-Zhang Yang

摘要:

考虑了模糊厌恶投资者的鲁棒时间一致均值-方差-偏度投资组合选择问题,该问题考虑了投资者的财富依赖风险厌恶和财富依赖偏度偏好以及模型的不确定性.利用扩展的Hamilton-Jacobi-Bellman-Isaacs(HJBI)系统,通过博弈论方法,刻画了该问题的鲁棒均衡投资策略和相应的均衡值函数.进一步,对于一类特殊的鲁棒时间一致均值-方差-偏度投资组合问题,得到了鲁棒均衡投资策略和相应的均衡价值函数的半封闭形式.最后,通过数值实验,给出了鲁棒均衡投资策略和效用损失的一些新结果。

英文摘要:

This paper considers a robust time-consistent mean-variance-skewness portfolio selection problem for an ambiguity-averse investor by taking into account wealth-dependent risk aversion and wealth-dependent skewness preference as well as model uncertainty. The robust equilibrium investment strategy and corresponding equilibrium value function are characterized for such a problem by employing an extended Hamilton-Jacobi-Bellman-Isaacs (HJBI) system via a game theoretic approach. Furthermore, the robust equilibrium investment strategy and corresponding equilibrium value function are obtained in semi-closed form for a special robust time-consistent mean-variance-skewness portfolio selection problem. Finally, some numerical experiments are provided to indicate several new findings concerned with the robust equilibrium investment strategy and the utility losses.
