Sampling error of the supremum of a Lévy process

open access: yes, 2011
This thesis is to study the expected difference of the continuous supremum and discrete maximum of a Lévy process that is often used in finance. We will show that the expected difference is a quantity that highly depends on the variational property of ...

Lévy Process-Driven Asymmetric Heteroscedastic Option Pricing Model and Empirical Analysis

open access: yesDiscrete Dynamics in Nature and Society, 2018
This paper describes the peak, fat tail, and skewness characteristics of asset price via a Lévy process. It applies asymmetric GARCH model to depict asset price’s random volatility characteristics and builds a GARCH-Lévy option pricing model with random ...

Financial Modeling and Option Theory with the Truncated Levy Process

open access: yes
In recent studies the truncated Levy process (TLP) has been shown to be very promising for the modeling of financial dynamics. In contrast to the Levy process, the TLP has finite moments and can account for both the previously observed excess kurtosis at

On Levy Processes Conditioned to Stay Positive [PDF]

open access: yes, 2006
We construct the law of Levy processes conditioned to stay positive under general hypotheses. We obtain a Williams type path decomposition at the minimum of these processes.

Bandit problems with Levy payoff processes

open access: yes, 2009
We study two-armed Levy bandits in continuous-time, which have one safe arm that yields a constant payoff s, and one risky arm that can be either of type High or Low; both types yield stochastic payoffs generated by a Levy process. The expectation of the Levy process when the arm is High is greater than s, and lower than s if the arm is Low.
