H. Ramlau-hansen,, Thiele's differential equation as a tool in product development in life insurance, Scandinavian actuarial journal , 1990(2-3), 1990, pp. 97-104
In the paper Thiele's differential equation is used to derive premium and reserve formulas for some new life products where the element of insurance is kept at a minimum. The products have been introduced in Denmark in order to provide policies with characteristics similar to pure savings accounts offered by banks and other financial institutions.
