Universality classes for general random matrix flows
Jacek Małecki, José Luis Pérez
We consider matrix-valued processes described as solutions to stochastic differential equations of very general form. We study the family of the empirical measure-valued processes…
Optimal bail-out dividends problem with transaction cost and capital injection constraint
Mauricio Junca, Harold Moreno-Franco, José Luis Pérez
We consider the bail-out optimal dividend problem under fixed transaction costs for a Lévy risk model. Furthermore, we consider the version with a constraint expected net present v…
Backbone decomposition of multitype superprocesses
Dorottya Fekete, Sandra Palau, Juan Carlos Pardo +1
In this paper, we provide a construction of the so-called backbone decomposition for multitype supercritical superprocesses. While backbone decompositions are fairly well-known for…
Optimality of multi-refraction dividend strategies in the dual model
Irmina Czarna, José Luis Pérez, Kazutoshi Yamazaki
We consider the multi-refraction strategies in two equivalent versions of the optimal dividend problem in the dual (spectrally positive Lévy) model. The first problem is a variant…
Convergence of the empirical spectral distribution of Gaussian matrix-valued processes
Arturo Jaramillo, Juan Carlos Pardo, José Luis Pérez
For a given normalized Gaussian symmetric matrix-valued process , we consider the process of its eigenvalues as well a…
American options under periodic exercise opportunities
José Luis Pérez, Kazutoshi Yamazaki
In this paper, we study a version of the perpetual American call/put option where exercise opportunities arrive only periodically. Focusing on the exponential Lévy models with i.i.…
