英文摘要:
We derive representations of local risk-minimization of call and put options for Barndorff-Nielsen and Shephard models: jump type stochastic volatility models whose squared volatility process is given by a non-Gaussian rnstein-Uhlenbeck process. The general form of Barndorff-Nielsen and Shephard models includes two parameters: volatility risk premium $\\beta$ and leverage effect $\\rho$. Arai and Suzuki (2015, arxiv:1503.08589) dealt with the same problem under constraint $\\beta=-\\frac{1}{2}$. In this paper, we relax the restriction on $\\beta$; and restrict $\\rho$ to $0$ instead. We introduce a Malliavin calculus under the minimal martingale measure to solve the problem.

中文摘要:
我们推导了Barndorff-Nielsen和Shephard模型的局部风险最小化表示:跳跃型随机波动率模型,其平方波动率过程由非高斯rnstein-Uhlenbeck过程给出。Barndorff-Nielsen和Shephard模型的一般形式包括两个参数:波动风险溢价$\\beta$和杠杆效应$\\rho$。Arai和Suzuki(2015,arxiv:1503.08589)在约束$\\beta=-\\frac{1}{2}$下处理了相同的问题。在本文中,我们放宽了对$\\beta$的限制;并将$\\rho$限制为0$。我们在最小鞅测度下引入Malliavin演算来解决这个问题。
