Kramkov和Sirbu(2006,2007)已经证明,在特定的等价鞅测度下,通过求解均值-方差套期保值问题,可以计算基于电力效用的价格和套期保值策略的一阶近似。为了避免由于数字变量的变化而引入额外的状态变量,我们提出了一种替代数字变量的表示方法。更具体地说,我们使用类似于Cerny和Kallsen(2007)关于均值-方差套期保值的半鞅特征来刻画相关量。将这些结果应用于指数L\'Evy过程以及Barndorff-Nielsen和Shephard型随机波动模型。

英文摘要:
  Kramkov and Sirbu (2006, 2007) have shown that first-order approximations of power utility-based prices and hedging strategies can be computed by solving a mean-variance hedging problem under a specific equivalent martingale measure and relative to a suitable numeraire. In order to avoid the introduction of an additional state variable necessitated by the change of numeraire, we propose an alternative representation in terms of the original numeraire. More specifically, we characterize the relevant quantities using semimartingale characteristics similarly as in Cerny and Kallsen (2007) for mean-variance hedging. These results are illustrated by applying them to exponential L\'evy processes and stochastic volatility models of Barndorff-Nielsen and Shephard type.
