障碍期权定价的半群展开

A Semi-group Expansion for Pricing Barrier Options

Takashi Kato, Akihiko Takahashi, Toshihiro Yamada

摘要:

本文提出了一种新的连续监测障碍期权定价的渐近展开方法。特别地,我们对障碍期权定价中的二阶抛物型偏微分方程的Cauchy-Dirichlet问题建立了一个半群展开格式.作为应用,我们在一个随机波动率模型下给出了一个具体的近似公式,并通过数值实验证明了其有效性。

英文摘要:

This paper presents a new asymptotic expansion method for pricing continuously monitoring barrier options. In particular, we develops a semi-group expansion scheme for the Cauchy-Dirichlet problem in the second-order parabolic partial differential equations (PDEs) arising in barrier option pricing. As an application, we propose a concrete approximation formula under a stochastic volatility model and demonstrate its validity by some numerical experiments.
