英文摘要:
In this paper we explore an identity in distribution of hitting times of a finite variation process (Yor\'s process) and a diffusion process (geometric Brownian motion with affine drift), which arise from various applications in financial mathematics. As a result, we provide analytical solutions to the fair charge of variable annuity guaranteed minimum withdrawal benefit (GMWB) from a policyholder\'s point of view, which was only previously obtained in the literature by numerical methods. We also use complex inversion methods to derive analytical solutions to the fair charge of the GMWB from an insurer\'s point of view, which is used in the market practice, however, based on Monte Carlo simulations. Despite of their seemingly different formulations, we can prove under certain assumptions the two pricing approaches are equivalent.

中文摘要:
在本文中,我们探讨了一个有限变分过程(约尔过程)和一个扩散过程(具有仿射漂移的几何布朗运动)的命中时间分布的恒等式,这两个过程产生于金融数学中的各种应用。因此,我们从投保人的角度提供了可变年金保证最低提取福利(GMWB)公平收费的分析解决方案,这在之前的文献中仅通过数值方法获得。我们还使用复杂的反演方法,从保险人的角度推导出GMWB公平收费的解析解,这在市场实践中使用,但基于蒙特卡罗模拟。尽管它们的公式似乎不同,但我们可以在某些假设下证明这两种定价方法是等价的。
