| dc.description | For a bivariate \Levy process $(ξ_t,η_t)_{t\geq 0}$ the generalised Ornstein-Uhlenbeck (GOU) process is defined as \[V_t:=e^{ξ_t}(z+\int_0^t e^{-ξ_{s-}}\ud η_s), t\ge0,\]where $z\in\mathbb{R}.$ We present conditions on the characteristic triplet of $(ξ,η)$ which ensure certain ruin for the GOU. We present a detailed analysis on the structure of the upper and lower bounds and the sets of values on which the GOU is almost surely increasing, or decreasing. This paper is the sequel to \cite{BankovskySly08}, which stated conditions for zero probability of ruin, and completes a significant aspect of the study of the GOU. | |
