英文摘要:
In a market with stochastic volatility and jumps, we consider a VIX-linked fee structure for variable annuity contracts with guaranteed minimum withdrawal benefits (GMWB). Our goal is to assess the effectiveness of the VIX-linked fee structure in decreasing the sensitivity of the insurer\'s liability to volatility risk. Since the GMWB payoff is highly path-dependent, it is particularly sensitive to volatility risk, and can also be challenging to price, especially in the presence of the VIX-linked fee. In this paper, we present an explicit weak solution for the value of the VA account and use it in Monte Carlo simulations to value the GMWB guarantee. Numerical examples are provided to analyze the impact of the VIX-linked fee on the sensitivity of the liability to changes in market volatility.

中文摘要:
在一个具有随机波动和跳跃的市场中,我们考虑了一个与波动率挂钩的费用结构,该结构适用于具有保证最低提取收益(GMWB)的可变年金合同。我们的目标是评估与波动率挂钩的费用结构在降低保险人责任对波动率风险的敏感性方面的有效性。由于GMWB的回报具有高度的路径依赖性,因此它对波动性风险特别敏感,也可能对价格构成挑战,尤其是在存在波动率挂钩费用的情况下。在本文中,我们给出了VA账户价值的显式弱解,并在蒙特卡罗模拟中使用它来评估GMWB担保。通过数值例子分析了与波动率指数挂钩的费用对负债对市场波动变化敏感性的影响。
