Analysis of a drawdown-based regime-switching Lévy insurance model

D Landriault, B Li, S Li - Insurance: Mathematics and Economics, 2015 - Elsevier
In this paper, we propose a new drawdown-based regime-switching (DBRS) Lévy insurance
model in which the underlying drawdown process is used to model an insurer's level of …
