Pricing Derivatives on Two Lé}vy-driven Stocks [PDF]
The aim of this work is to study the pricing problem for derivatives depending on two stocks driven by a bidimensional Lévy process. The main idea is to apply Girsanov's Theorem for Lévy processes, in order to reduce the posed problem to the pricing of a

Levy Noise Affects Ornstein–Uhlenbeck Memory
This paper investigates the memory of the Ornstein–Uhlenbeck process (OUP) via three ratios of the OUP increments: signal-to-noise, noise-to-noise, and tail-to-tail. Intuition suggests the following points: (1) changing the noise that drives the OUP from

A Multivariate Time-Changed Lévy Model for Financial Applications [PDF]
The purpose of this paper is to define a bivariate L´evy process by subordination of a Brownian motion. In particular we investigate a generalization of the bivariate Variance Gamma process proposed in Luciano and Schoutens [8] as a price process.

Symmetry and Time Changed Brownian Motions [PDF]
In this paper we examine which Brownian Subordination with drift exhibits the symmetry property introduced by Fajardo and Mordecki (2006b). We obtain that when the subordination results in a Lévy process, a necessary and sufficient condition for the ...

Asymptotic equivalence of jumps Lévy processes and their discrete counterpart
Shorter version focusing on the statistical analysis of the Lévy measure. A new example has been added.We establish the global asymptotic equivalence between a pure jumps Lévy process $\{X_t\}$ on the time interval $[0,T]$ with unknown Lévy measure $\nu$
