Optimality of a barrier strategy in a spectrally negative Lévy model with a level-dependent intensity of bankruptcy
Dante Mata, Jean-François Renaud
We consider de Finetti's stochastic control problem for a spectrally negative Lévy process in an Omega model. In such a model, the (controlled) process is allowed to spend time und…

Optimal withdrawals in a general diffusion model with control rates subject to a state-dependent upper bound
Hélène Guérin, Dante Mata, Jean-François Renaud +1
We consider a classical stochastic control problem in which a diffusion process is controlled by a withdrawal process up to a termination time. The objective is to maximize the exp…
