Policyholder Behavior in the Tail Project–Annuity Lapse Modeling
Research Projects – Risk Management
The Society of Actuaries' (SOA) Policyholder Behavior in the Tail Group was formed to develop better estimates of policyholder behavior in extreme situations (a.k.a. the tail of the distribution). To further its mission, the group commissioned two research papers examining the modeling of annuity lapse rates under extreme conditions. Funding for the papers was provided by the SOA's Committee on Finance Research.
The resulting papers provide different perspectives on how these rates may be modeled. Changki Kim's paper applies a Logit model to Korean and U.S. experience. Sam Cox and Yijia Lin employ a different approach that relies on a Tobit model in its analysis of annuity lapse rates. Cox and Lin also suggest that a Count model may be more appropriate if more expanded lapse data were available.
