Abstract
This chapter focuses on the evaluation of the transform of the ruin probability in a regime-switching (or Markov modulated) version of the standard Cramér-Lundberg model. In the derivation various elements from Chap. 1 are relied upon, in particular the idea of conditioning on the first event and the Wiener-Hopf decomposition. The results established in this chapter also facilitate the analysis of the conventional (non-modulated, that is) Cramér-Lundberg model over a phase-type horizon (rather than an exponentially distributed horizon). Finally, we comment on a setup in which the model parameters are periodically resampled, and argue that it fits in the modelling framework discussed in the chapter.
