英文摘要:
This paper proposes to model asset price dynamics with a mixture of diffusion processes where the instantaneous volatility of the underlying diffusion process contains a random vector. The marginal probability distributions of the proposed process can match exactly the risk-neutral distributions implied by both spot vanilla options and forward start options. We can also derive the explicit pricing formula for derivatives that have a closed-form solution under Generalized Geometric Brownian Motion.

中文摘要:
本文提出了一种混合扩散过程的资产价格动力学模型,其中基础扩散过程的瞬时波动率包含一个随机向量。该过程的边际概率分布可以精确匹配即期普通期权和远期启动期权所隐含的风险中性分布。我们还可以导出在广义几何布朗运动下具有闭式解的导数的显式定价公式。
