Parisian quasi-stationary distributions for asymmetric L\'evy processes

Probability 2016-04-15 v2

Abstract

In recent years there has been some focus on quasi-stationary behaviour of an one-dimensional L\'evy process XX, where we ask for the law P(Xtdyτ0>t)P(X_t\in dy | \tau^-_0>t) for tt\to\infty and τ0=inf{t0:Xt<0}\tau_0^-=\inf\{t\geq 0: X_t<0\}. In this paper we address the same question for so-called Parisian ruin time τθ\tau^\theta, that happens when process stays below zero longer than independent exponential random variable with intensity θ\theta.
