Selected Risk classification in life and health papers
Risk classification and actuarial pricing is at the heart of our team’s expertise. Besides classical applications to P&C insurance, our senior actuaries also considered effective methods to include risk factors in mortality or morbidity rates.
The following paper explains how to apply Poisson regression tools (GAMs, GBMs or trees) to explain variations in mortality and morbidity rates:

This work greatly benefitted from interactions with AXA teams and is based on two previous case studies conducted with actuarial teams from the German reinsurer Munich Re and the French reinsurer SCOR:

Our team also considered practical ways to perform actuarial calculations in segmented life and health portfolios. See for instance
