报告摘要: In this work, we propose some variable
annuities (VAs) with guaranteed minimum death benefits (GMDB) which depend on the combined survival status of two lives, e.g., for a married couple. We assume a general exponential Levy process for the risky asset price, and propose to combine the bivariate Laguerre series expansions with the projection method for the valuation of joint life VAs. We obtain explicit closed-form formulas for three types of GMDB riders. Numerical examples demonstrate that the proposed method is highly accurate and efficient.
