Mortality Modeling With Non‐Gaussian Innovations and Applications to the Valuation of Longevity Swaps

Abstract: This article provides an iterative fitting algorithm to generate maximum likelihood estimates under the Cox regression model and employs non-Gaussian distributions-the jump diffusion (JD), variance gamma (VG), and normal inverse Gaussian (NIG) distributions-to model the error terms of the Renshaw and Haberman (2006) (RH) model. In terms of mean absolute percentage error, the RH model with non-Gaussian innovations provides better mortality projections, using 1900-2009 mortality data from England and Wales, Fran… Show more

“…In this section, we demonstrate the benefit of capturing the geographical structure with the LSHAC-based multicountry mortality model by applying it to pricing and hedging a survivor index swap. Such derivative has been studied extensively in Blake et al (2013), Dawson et al (2010), Dowd et al (2006), and Wang, Huang, and Liu (2013). We consider a survival index for a cohort of x 0 = 65, which follows the framework of Wang, Yang, and Huang (2015), with the underlying survivor index based on multipopulation survivor distributions in order to reduce basis risk.…”

“…In addition, some articles have focused on comparing existing models in the literature (e.g., Stallard, ). Another strand of the literature is using well‐known techniques from econometrics or other disciplines to model multipopulation mortality (e.g., Hatzopoulos and Haberman, ; Lin, Liu, and Yu, ; Wang, Huang, and Liu, ; Yang and Wang, ; Zhou et al, ).…”
