期权定价的路径中偏差

Pathwise moderate deviations for option pricing

Antoine Jacquier, Konstantinos Spiliopoulos

摘要:

我们提供了一个统一的治疗路径的中度偏差模型中常用的金融应用程序,并为相关的集成泛函。适当的缩放使我们能够将这些结果转化为小时间,大时间和尾部渐近扩散,以及期权价格和实现的方差。顺便说一句,我们强调了中等偏差率函数和它们的大偏差对应物之间的一些直观关系;这些结果对于数值目的是有用的,因为大偏差率函数通常很难计算。

英文摘要:

We provide a unifying treatment of pathwise moderate deviations for models commonly used in financial applications, and for related integrated functionals. Suitable scaling allows us to transfer these results into small-time, large-time and tail asymptotics for diffusions, as well as for option prices and realised variances. In passing, we highlight some intuitive relationships between moderate deviations rate functions and their large deviations counterparts; these turn out to be useful for numerical purposes, as large deviations rate functions are often difficult to compute.
