Matrix calculations for inhomogeneous Markov reward processes, with applications to life insurance and point processes

Mogens Bladt, Søren Asmussen, Mogens Steffensen

A multi--state life insurance model is naturally described in terms of the intensity matrix of an underlying (time--inhomogeneous) Markov process which describes the dynamics for t…

A factorization of a Lévy process over a phase-type horizon

Søren Asmussen, Jevgenijs Ivanovs

This note provides a factorization of a Lévy pocess over a phase-type horizon given the phase at the supremum, thereby extending the Wiener-Hopf factorization for exponenti…

Tail asymptotics of light-tailed Weibull-like sums

Søren Asmussen, Enkelejd Hashorva, Patrick J. Laub +1

We consider sums of i.i.d. random variables with tails close to for some . Asymptotics developed by Rootzén (1987) and Balkema, Klüppelberg & Resnick (1993)…

Discretization error for a two-sided reflected Lévy process

Søren Asmussen, Jevgenijs Ivanovs

An obvious way to simulate a Lévy process is to sample its increments over time , thus constructing an approximating random walk . This paper considers the error…

On the longest gap between power-rate arrivals

Søren Asmussen, Jevgenijs Ivanovs, Johan Segers

Let be the longest gap before time in an inhomogeneous Poisson process with rate function proportional to for some . It is shown that $λ_tL_t-b…
