Abstract

This paper discusses the calculation of the moments of the present value of the profit on a sickness insurance policy. The mathematical model for sickness insurance is a three-state continuous time semi-Markov process which is currently being investigated in the United Kingdom with a view to its practical implementation. The formulae derived for the moments of the profit are integral equations whose numerical solution results in a set of recursive formulae. The methods used to derive these formulae are also used to derive formulae for the aggregate amount of time spent sick; a problem discussed by Seal (1970). Numerical examples relating to both these problems are given. © 1990.
