具有时间和状态依赖风险规避的均值-方差-效用投资组合选择

Mean-variance-utility portfolio selection with time and state dependent risk aversion

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

摘要:

在均值-方差-效用框架下,我们提出了一个新的投资组合选择模型,该模型允许财富和时间同时影响投资过程中的风险规避。在博弈论框架下求解了模型,并解析地推导出了均衡投资(消费)政策。这一结果与最优投资策略在很大程度上取决于投资者的财富和未来收入-消费平衡以及连续的最优消费过程在很大程度上取决于投资者的消费偏好这一事实相吻合。

英文摘要:

Under mean-variance-utility framework, we propose a new portfolio selection model, which allows wealth and time both have influences on risk aversion in the process of investment. We solved the model under a game theoretic framework and analytically derived the equilibrium investment (consumption) policy. The results conform with the facts that optimal investment strategy heavily depends on the investor's wealth and future income-consumption balance as well as the continuous optimally consumption process is highly dependent on the consumption preference of the investor.
