My work in this area began with the Cairns-Blake-Dowd (CBD) mortality model (2006) which rapidly became adopted as one of the standard models in the area (“A two factor model ...”). Since then Andrew Cairns, David Blake and I have been working on various extensions to the original CBD model, mainly to incorporate the impact of cohort or year-of-birth effects (see, e.g., “Modelling and management of mortality risk ...” and “A quantitative comparison ...”).
An introduction/overview of the CBD model and its various extensions can be found in the CBD Model homepage. This homepage includes a page about the model, a demo and downloadable Excel workbook that allows the user to estimate the model’s parameters.
Within the mortality/longevity area, I have been involved mainly in the following topics:
