Abstract:
In this paper we consider the risk process described by a piecewise deterministic Markov processes (PDMP). We; mainly discuss the distribution of the deficit at ruin for the risk process. We derive the integro-differential equation satisfied by this distribution. We obtain the explicit expressions for it, for certain choices of the claim amount distribution.
