Extending Time-Changed Lévy Asset Models Through Multivariate Subordinators [PDF]

open access: yes
The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence.

Duality and Derivative Pricing with Lévy Processes [PDF]

open access: yes
The aim of this work is to use a duality approach to study the pricing of 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

Skewness Premium with Lévy Processes [PDF]

open access: yes
We study the skewness premium (SK) introduced by Bates (1991) in a general context using Lévy Processes. We obtain sufficient and necessary conditions for Bate's x% rule to hold.

Nonparametric adaptive estimation of linear functionals for low frequency observed Lévy processes [PDF]

open access: yes
For a Lévy process X having finite variation on compact sets and finite first moments, µ( dx) = xv( dx) is a finite signed measure which completely describes the jump dynamics.

Hyperfinite stochastic integration for Lévy processes with finite-variation jump part [PDF]

open access: yes
This article links the hyperfinite theory of stochastic integration with respect to certain hyperfinite Lévy processes with the elementary theory of pathwise stochastic integration with respect to pure-jump Lévy processes with finite-variation jump part.

Low-frequency estimation of continuous-time moving average Lévy processes [PDF]

open access: yes, 2016
In this paper we study the problem of statistical inference for a continuoustime moving average Lévy process of the form Zt=∫ℝκ(t-s)dLs, t∈ℝ with a deterministic kernel κ and a Lévy process L. Especially the estimation of the Lévy measure v of L from

Cliquet option pricing with Meixner processes

open access: yesModern Stochastics: Theory and Applications, 2018
We investigate the pricing of cliquet options in a geometric Meixner model. The considered option is of monthly sum cap style while the underlying stock price model is driven by a pure-jump Meixner–Lévy process yielding Meixner distributed log-returns ...

A Comparison among Portfolio Selection Strategies with Subordinated Lévy Processes [PDF]

open access: yes, 2007
In this paper we describe portfolio selection models using Lévy processes. The contribution consists in comparing some portfolio selection strategies under different distributional assumptions. We first implement portfolio models under the hypothesis the

OPTION PRICING UNDER LÉVY PROCESSES: A UNIFYING FORMULA [PDF]

open access: yes
A new option pricing formula is presented that unifies several results of the existing literature on pricing exotic options under Lèvy processes. To demonstrate the flexibility of the formula a few examples are given which provide new valuation formulas ...
