摘要: In some former contributions, the authors investigated actuarial quantities with stochastic interest rates. a first model, randomness is modelled by means of an ordinary Wiener process, and as consequence negative rates are possible. A second model provides tool to avoid these rates, which can be necessary in particular situations. This paper wants present alternative solution problem new will implemented case annuity certain perpetuity.
