随机系数均值-方差投资组合选择与方差套期保值:闭环均衡策略

Mean-variance portfolio selection and variance hedging with random coefficients: closed-loop equilibrium strategy

Tianxiao Wang

摘要:

本文在非马尔可夫框架下讨论了动态均值-方差投资组合选择问题和动态方差套期保值问题。首次通过统一的方法分别得到了这些问题的显式闭环平衡策略。一些新的有趣的事实出现在均值方差问题与常数风险厌恶。例如,只要无风险收益率是随机的,均衡策略仍然可以依赖于初始财富。另外,在非马尔可夫背景下,闭环均衡策略和开环均衡策略与初始财富的关系是相同的,并且当无风险收益率是确定的时,闭环均衡策略和开环均衡策略恰好相等。

英文摘要:

In this paper, both dynamic mean-variance portfolio selection problems and dynamic variance hedging problems are discussed under non-Markovian framework. Explicit closed-loop equilibrium strategies of these problems are respectively obtained via a unified approach for the first time. Several new interesting facts arise in mean-variance problems with constant risk aversion. For example, it is shown that equilibrium strategies are still allowed to rely on initial wealth as long as risk-free return rate is random. In addition, the closed-loop equilibrium strategy and open-loop equilibrium strategy have the same connection with initial wealth in non-Markovian setting, and they happen to equal to each other if only risk-free return rate is deterministic.
