Potential Densities for Taxed Spectrally Negative Lévy Risk Processes

open access: yesRisks, 2019
This paper revisits the spectrally negative Lévy risk process embedded with the general tax structure introduced in Kyprianou and Zhou (2009). A joint Laplace transform is found concerning the first down-crossing time below level 0.

On the Depletion Problem for an Insurance Risk Process: New Non-ruin Quantities in Collective Risk Theory [PDF]

open access: yes, 2014
The field of risk theory has traditionally focused on ruin-related quantities. In particular, the socalled Expected Discounted Penalty Function has been the object of a thorough study over the years.

De Finetti’s Control Problem with Parisian Ruin for Spectrally Negative Lévy Processes

open access: yesRisks, 2019
We consider de Finetti’s stochastic control problem when the (controlled) process is allowed to spend time under the critical level. More precisely, we consider a generalized version of this control problem in a spectrally negative Lévy model ...

On the time spent in the red by a refracted L\'evy risk process [PDF]

open access: yes, 2013
In this paper, we introduce an insurance ruin model with adaptive premium rate, thereafter refered to as restructuring/refraction, in which classical ruin and bankruptcy are distinguished.

Three Essays on Stopping

open access: yesRisks, 2019
First, we give a closed-form formula for first passage time of a reflected Brownian motion with drift. This corrects a formula by Perry et al. (2004). Second, we show that the maximum before a fixed drawdown is exponentially distributed for any drawdown,

Probabilistic aspects of critical growth-fragmentation equations [PDF]

open access: yes, 2015
The self-similar growth-fragmentation equation describes the evolution of a medium in which particles grow and divide as time proceeds, with the growth and splitting of each particle depending only upon its size.

Optimal Bail-Out Dividend Problem with Transaction Cost and Capital Injection Constraint

open access: yesRisks, 2019
We consider the optimal bail-out dividend problem with fixed transaction cost for a Lévy risk model with a constraint on the expected present value of injected capital.

Power identities for Lévy risk models under taxation and capital injections

open access: yesStochastic Systems, 2014
In this paper we study a spectrally negative Lévy process which is refracted at its running maximum and at the same time reflected from below at a certain level. Such a process can for instance be used to model an insurance surplus process subject to tax

Asymptotic behavior of local times of compound Poisson processes with drift in the infinite variance case [PDF]

open access: yes, 2012
Consider compound Poisson processes with negative drift and no negative jumps, which converge to some spectrally positive L\'evy process with non-zero L\'evy measure.
