Basic Concepts of Live Insurance Mathematics

Abstract

The conjunction of a financial model and a mortality model is a life insurance model. The classical life insurance model is the conjunction of the classical financial model (with constant interest rate i) and the classical mortality model (with survival probabilities resulting from a continuous life table l _ξ). The classical life insurance model is adopted if nothing else is stated explicitly. Some developments have direct generalizations in case of variable interest rates: it is enough to replace the discount factor v^τ by v_τ, everywhere.
