摘要
In the classical model of risk theory a martingale method is used to compute the distributions of the first and last passage times (and of their difference) of the surplus process at a given level. As a byproduct a certain probabilistic identity related to Lagrange's formula is derived; furthermore Consul's generalized Poisson distribution is explained. © 1990.
