Abstract
This paper introduces a fair valuation framework for pricing variable annuity liabilities and their embedded guarantee riders within a dynamic multi-period context. We focus on variable annuities featuring the Guaranteed Lifetime Withdrawal Benefit (GLWB) rider, which exposes policyholders to both financial and longevity risks. We employ a fair dynamic valuation method that is market-consistent, actuarially-consistent, and time-consistent. Our findings demonstrate that this approach effectively establishes fair management fee rates, aligning with prior research and industry surveys. Furthermore, we highlight the potential for significant reductions in liability valuation, and consequently, GLWB rider pricing, through effective management of longevity risk within the insurer's net liability.
期刊介绍：
Insurance: Mathematics and Economics publishes leading research spanning all fields of actuarial science research. It appears six times per year and is the largest journal in actuarial science research around the world.
Insurance: Mathematics and Economics is an international academic journal that aims to strengthen the communication between individuals and groups who develop and apply research results in actuarial science. The journal feels a particular obligation to facilitate closer cooperation between those who conduct research in insurance mathematics and quantitative insurance economics, and practicing actuaries who are interested in the implementation of the results. To this purpose, Insurance: Mathematics and Economics publishes high-quality articles of broad international interest, concerned with either the theory of insurance mathematics and quantitative insurance economics or the inventive application of it, including empirical or experimental results. Articles that combine several of these aspects are particularly considered.
