分数和粗糙波动率模型中的CVA

CVA in fractional and rough volatility models

Elisa Alòs, Fabio Antonelli, Alessandro Ramponi, Sergio Scarlatti

摘要:

在这项工作中,我们提出了一个一般的表示公式的脆弱的欧式期权的价格,和相关的CVA随机(粗糙或不)波动率模型的基础价格,当承认相关的违约事件。我们专门为一些波动率模型,我们提供价格近似,基于表示公式。我们数值研究其准确性,比较结果与蒙特卡罗模拟,我们运行的误差的理论研究。我们还介绍了粗糙度对索赔价格的影响的开创性研究。

英文摘要:

In this work we present a general representation formula for the price of a vulnerable European option, and the related CVA in stochastic (either rough or not) volatility models for the underlying's price, when admitting correlation with the default event. We specialize it for some volatility models and we provide price approximations, based on the representation formula. We study numerically their accuracy, comparing the results with Monte Carlo simulations, and we run a theoretical study of the error. We also introduce a seminal study of roughness influence on the claim's price.
