在对广义期望效用理论进行综述的基础上,将该理论与一致性性风险测度联系起来,并利用广义期望效用理论中的Choquet期望效用函数,提出了一个主观概率调整的一致性风险测度.以中国股市中的一个资产组合为样本,利用二元随机波动率模型对资产组合收益率分布进行描述,并使用马尔克夫链蒙特卡罗的模拟方法对该分布进行模拟,计算了主观概率调整的风险值.
Starting from a review of the general expected utility theory,which was then associated with the new research progress in the financial risk measurement,a probability adjusted coherent financial risk measurement was put forward based on the Choquet expected utility function.A bivariate stochastic volatility model was used to describe a portfolio return distribution from Chinese stock market.The Markov Chain Monte Carlo method was applied to simulate the distribution and obtain the probability adjusted coherent financial risk value.
