状态转换跳跃扩散的Fourier变换方法与远期启动期权的定价

Fourier Transform Methods for Regime-Switching Jump-Diffusions and the Pricing of Forward Starting Options

Alessandro Ramponi

摘要:

本文考虑了一个参数由有限状态空间上的连续时间平稳马尔可夫链驱动的跳-扩散动力学模型,作为欧式未定权益的基础模型。对于这类过程,我们首先概述了傅立叶变换方法在对数价格和对数罢工有效地计算各种类型的期权的价值,并作为一个具体的应用例子,我们提出了一些数值结果内的两个状态状态转换版本的默顿跳扩散模型。然后,我们开发了一个封闭形式的解决方案的定价问题的远期启动期权,并使用这个结果来近似的价值,这样的衍生工具在一般的随机波动率框架。

英文摘要:

In this paper we consider a jump-diffusion dynamic whose parameters are driven by a continuous time and stationary Markov Chain on a finite state space as a model for the underlying of European contingent claims. For this class of processes we firstly outline the Fourier transform method both in log-price and log-strike to efficiently calculate the value of various types of options and as a concrete example of application, we present some numerical results within a two-state regime switching version of the Merton jump-diffusion model. Then we develop a closed-form solution to the problem of pricing a Forward Starting Option and use this result to approximate the value of such a derivative in a general stochastic volatility framework.
