Abstract:

In this article, a threshold dividend strategy is used for classical risk model. Under this dividend strategy, certain probability of ruin, which occurs in case of constant barrier strategy, is avoided. Using the strong Markov property of the surplus process and the distribution of the deficit in classical risk model, the survival probability for this model is derived, which is more direct than that in Asmussen (2000, P195, Proposition 1.10). The occupation time of non-dividend of this model is also discussed by means of Martingale method.

Key words: hreshold dividend strategy, ruin, occupation time, piecewise deterministic Markov process
