Preface

Since Black and Scholes have presented their seminal article on option pricing in 1973, there has been a lot of scientific activity in this research area. In 1995, Eberlein and Keller proposed a more realistic approach, the hyperbolic model. In this thesis we generalize their results to other than standard European options.

The content of the chapters is as follows. In Chapter 1 we give basic properties of L´evy processes and infinitely divisible distributions. We introduce the generalized hyperbolic distribution, and the corresponding L´evy motions, which will be needed for modelling stock prices. Chapter 2 gives a brief introduction to the field of option pricing as well as to Monte Carlo and Quasi-Monte Carlo methods. We also compare European option prices in the hyperbolic model and in the Black-Scholes model. In Chapter 3 we simulate Asian Esscher option prices based on the general mean using Monte Carlo methods with variance reduction techniques and Quasi-Monte Carlo methods. In Chapter 4 the normal inverse Gaussian (NIG) model in the context of Asian options is investigated. We give approximation and simulation results and use stop-loss transforms to obtain uppers bound for these Esscher option prices. Chapter 5 contains algorithms used for the simulation of American options prices. In Chapter 6 we discuss an alternative to the Esscher martingale measure, namely the minimal entropy martingale measure, to obtain option prices in the NIG model. And finally Chapter 7 gives a short survey on multi-asset options in the NIG model.

I take this opportunity to thank my thesis advisor O.Univ.-Prof. Dr. Robert F. Tichy for his encouragement, confidence and support. I would also like to thank Univ.-Prof. Dr. Gerhard Larcher for his promotion and support. Furthermore, I would like to thank all those, who contributed in various ways to the development of this thesis, especially Hansjörg Albrecher, Jürgen Hartinger, Gunther Leobacher and Elmar Teufl. Last but not least I would like to thank my parents for their support and credit.

Chapter 1
Hyperbolic L´evy processes
1.1Introduction

L´evy processes were first characterized by Paul L´evy in the 1930s. These processes are an excellent tool for modelling price processes in mathematical finance. Compared with semimartingales they have a simple structure. Thus, they can be used for practical applications. An overview on using L´evy processes in finance is given by BarndorffNielsen and Shepard [BS00].

In this chapter we give basic definitions and results concerning L´evy processes and

the related infinitely divisible distributions, in particular the generalized hyperbolic distribution. This distribution plays an important role in the context of modelling financial derivatives (see e.g. Eberlein [Eb98]).

This chapter contains parts of the articles The loghyperbolic distribution: Basic properties and random number generation [Pr01] by Predota and ML-estimators for parameters of hyperbolic densities in finance [PT01] by Predota and Tichy. [...]
