| Abstract: | The duration of negative surplus of a compound Poisson-Geommetric risk model was studied.By a new method different from the traditional Martingale methed,and taking full advantage of the strong Markov property of the surplus process,an integral differential equation of a conditional moment generating function for the first duration of negative surplus was obtained.Finally,the explicit expression is given when the claim is exponential distribution. |
