基于G-期望的稳健均值-方差套期保值

Robust Mean-Variance Hedging via G-Expectation

Francesca Biagini, Jacopo Mancin, Thilo Meyer Brandis

摘要:

本文在G-期望框架下研究均值-方差套期保值问题。我们利用G-鞅表示定理和相关的概率工具进行分析,在一个连续的金融市场中有两种资产,其中贴现的风险资产被建模为对称的G-鞅。通过处理越来越大的或有债权类别,我们能够明确地计算出最优策略的一般假设下的或有债权的形式。

英文摘要:

In this paper we study mean-variance hedging under the G-expectation framework. Our analysis is carried out by exploiting the G-martingale representation theorem and the related probabilistic tools, in a contin- uous financial market with two assets, where the discounted risky one is modeled as a symmetric G-martingale. By tackling progressively larger classes of contingent claims, we are able to explicitly compute the optimal strategy under general assumptions on the form of the contingent claim.
