报告题目:Valuation of Guaranteed Lifelong Withdrawal Benefit with Long-term Care Option

报告摘要:In this work, under the stochastic interest rate framework, we consider the valuation of a Guaranteed Lifelong Withdrawal Benefit (GLWB) annuity product by explicitly incorporating the health state of the policyholder through the long-term care (LTC) option. The product provides policyholder with protection against longevity risk and market downturns, as well as financial support when facing long-term care needs. Within the context of dynamic withdrawals, the valuation of the GLWB annuity is characterized as a stochastic optimal control problem. We introduce a novel bang-bang analysis approach without the usual convexity assumption in literature, and prove that the optimal withdrawal strategies for the policyholder are constrained to a finite set. Furthermore, we conducted a sensitivity analysis of the determinants of the price of GLWB annuities. Specifically, we investigate the impact of fluctuations in interest rates and gender factors on the fair fee of GLWB and optimal withdrawal strategies, and provide economic explanations.
