英文摘要:
We introduce an affine extension of the Heston model where the instantaneous variance process contains a jump part driven by $\\alpha$-stable processes with $\\alpha\\in(1,2]$. In this framework, we examine the implied volatility and its asymptotic behaviors for both asset and variance options. Furthermore, we examine the jump clustering phenomenon observed on the variance market and provide a jump cluster decomposition which allows to analyse the cluster processes.

中文摘要:
我们引入了赫斯顿模型的仿射扩展,其中瞬时方差过程包含由$\\α$-稳定过程驱动的跳跃部分,其中$\\α$\\ in(1,2]$。在此框架中,我们研究了资产和方差期权的隐含波动率及其渐近行为。此外,我们还研究了方差市场上观察到的跳跃聚类现象,并提供了跳跃聚类分解,用于分析聚类过程。
