An observation‐driven state‐space model for claims size modelling

Canadian Journal of Statistics, Volume 54, Issue 1, March 2026.
Abstract State‐space models are popular in econometrics. Recently, these models have gained some popularity in the actuarial literature. The best known state‐space models are of the Kalman‐filter type. These are called parameter‐driven because the observations do not impact the state‐space dynamics.

Optimal dividends for a NatCat insurer in the presence of a climate tipping point

Canadian Journal of Statistics, Volume 54, Issue 1, March 2026.
Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.
