Foreword This doctoral thesis was written during my employment as a research assistent at the Institute of Accounting and Taxation at the University of Graz under the direction of Univ.-Prof. Dr. Rainer Niemann. To him I feel very grateful for offering me the chance to get to know the world of science. Furthermore, I thank Univ.-Prof. Dr. Rainer Niemann for the committed supervision of my doctoral thesis and for giving me valuable advice and support always when needed. He always encouraged new ideas and supported participation at conferences and exchange with colleagues from other universities. I thank Univ.-Prof. Dr. Sabine Kanduth-Kristen for her interest in my scien- tific work and her kind willingness to be my second supervisor. I am especially grateful that I had two colleagues and companions during my time as a research assistent. I thank Silke R¨ungerand Andrea Gauper for being my dicussants, critics and friends. Furthermore I want to thank my parents Maritta and Wilhelm Gruber. With- out their believe in my abilities and their financial and moral support through- out my studies this doctoral thesis would not have been possible. Finally, I owe very special thanks to my husband Werner for the patient and loving support and his unresting moral encouragement. To him I dedicate this work.
