Description: This is the Quantification and Management of Longevity Risk in China paper authored by Johnny Li, Kenneth Q. Zhou and Wai-Sum Chan for Session 1A of the January 13-15, 2020 Living to 100 Symposium in Orlando, Florida.

Description: In this paper, we investigate the dynamics of the Lee-Carter mortality index parameter kt. Specifically, we perform statistical hypothesis tests to examine whether the mortality indexes for Canada, England and Wales and the United States are best described by stochastic trends difference stationary models or deterministic trends trend stationary models. The empirical results favor broken-trend stationary models over difference stationary models, which are used in most previous applications of the Lee-Carter method. The results also give strong statistical evidence that the rates of mortality decline for the three populations have significantly accelerated in mid-1970s.
