英文摘要:
This paper proposes a market consistent valuation framework for variable annuities with guaranteed minimum accumulation benefit, death benefit and surrender benefit features. The setup is based on a hybrid model for the financial market and uses time-inhomogeneous L\\\'evy processes as risk drivers. Further, we allow for dependence between financial and surrender risks. Our model leads to explicit analytical formulas for the quantities of interest, and practical and efficient numerical procedures for the evaluation of these formulas. We illustrate the tractability of this approach by means of a detailed sensitivity analysis of the price of the variable annuity and its components with respect to the model parameters. The results highlight the role played by the surrender behaviour and the importance of its appropriate modelling.

中文摘要:
本文提出了一个具有保证最低累积收益、死亡收益和退保收益特征的可变年金市场一致性估值框架。该设置基于金融市场的混合模型,并使用时间不均匀的列维过程作为风险驱动因素。此外,我们考虑了财务风险和退保风险之间的依赖性。我们的模型导出了感兴趣的量的显式分析公式,以及评估这些公式的实用有效的数值程序。我们通过对可变年金及其组成部分的价格与模型参数的详细敏感性分析,说明了这种方法的可操作性。结果强调了投降行为所起的作用及其适当建模的重要性。
