Monte-Carlo simulation results in estimating a pure-jump Cox-Ingersoll-Ross process [PDF]

open access: yesESAIM: Proceedings and Surveys
We consider a pure-jump stable Cox-Ingersoll-Ross (α-stable CIR) process driven by a non-symmetric stable Lévy process with jump activity α ∈ (1,2), for which estimators of the drift, scaling and jump activity parameters from high-frequency observations ...

L_1-distance for additive processes with time-homogeneous L\'evy measures [PDF]

open access: yes, 2014
We give an explicit bound for the $L_1$-distance between two additive processes of local characteristics $(f_j(\cdot),\sigma^2(\cdot),\nu_j)$, $j = 1,2$. The cases $\sigma =0$ and $\sigma > 0$ are both treated.

Revisiting variance gamma pricing : an application to S&P500 index options [PDF]

open access: yes, 2015
We reformulate the Lévy-Kintchine formula to make it suitable for modelling the stochastic time-changing effects of Lévy processes. Using Variance-Gamma (VG) process as an example, it illustrates the dynamic properties of a Lévy process and revisits the ...

Fractional diffusion models of option prices in markets with jumps. [PDF]

open access: yes
Most of the recent literature dealing with the modeling of financial assets assumes that the underlying dynamics of equity prices follow a jump process or a Lévy process. This is done to incorporate rare or extreme events not captured by Gaussian models.

Expansion of Lévy Process Functionals and Its Application in Statistical Estimation [PDF]

open access: yes
In this paper, expansions of functionals of Lévy processes are established under some Hilbert spaces and their orthogonal bases. From practical standpoint, both time-homogeneous and time-inhomogeneous functionals of Lévy processes are considered. Several

Robust Superhedging with Jumps and Diffusion [PDF]

open access: yes, 2015
We establish a nondominated version of the optional decomposition theorem in a setting that includes jump processes with nonvanishing diffusion as well as general continuous processes.

BSDEs and log-utility maximization for Lévy processes

open access: yesModern Stochastics: Theory and Applications, 2019
In this paper we establish the existence and the uniqueness of the solution of a special class of BSDEs for Lévy processes in the case of a Lipschitz generator of sublinear growth.

Equivalent Martingale Measures and Lévy Processes [PDF]

open access: yes
In this paper we compute equivalent martingale measures when the asset price return is modeled by a Lévy process.

Markov Regime Switching of Stochastic Volatility Lévy Model on Approximation Mode

open access: yesJournal of Applied Mathematics, 2013
This paper deals with financial modeling to describe the behavior of asset returns, through consideration of economic cycles together with the stylized empirical features of asset returns such as fat tails.
