摘要:
In this paper, we derive the Laplace transform of occupation times of intervals until last passage times for spectrally negative Levy processes. Motivated by [2], the last passage times before an independent exponential variable are investigated. By a dual argument, explicit formulas are obtained and expressed as a modified version of the analytical identities introduced in Loeffen et al. [13]. As an application, a corridor option and an Omega risk model are studied here.
