(William Blake, 1757 - 1827) i ACKNOWLEDGMENTS During my time as a PhD student I had not only one, but two supervisors to whom I am very grateful. For most of the time I was supervised by Özgür Gürerk, who guided me through my first two research projects and enabled me to publish my first scientific paper. Özgür, thank you very much for your patience and support. When I needed a new supervisor, I was glad that Christine Harbring agreed to step into the role for the remainder of the time. Thank you, Christine, your supporting feedback and encouragement in the final phase really helped me a lot. Special thanks go to Thomas Lauer for collaborating on my first two projects and helping me with his profound expertise in econometrics. My thanks also go to Christian Grund, who made himself available as a reviewer for this dissertation. As a research associate, I had the pleasure of being surrounded by wonderful colleagues. I am thankful to Andreas Staffeldt, Britta Butz, Frederik Graff, Jan Wilhelm, Luca Carduck- Eick, Lucas Braun, Maik Theelen, and Nicolas Meier, for creating such a pleasant atmosphere and many joyful memories. Regarding Part III of this dissertation, I express my gratitude to Jan Wilhelm, who initially approached me with the underlying idea. Although it was intended as a joint project, Jan left research to pursue other goals, so I wrote the paper on my own. Jan, I hope you are satisfied with the result. I further thank our secretary Anja Uttich who assisted in many ways and Christine Stibbe for transforming my English into a comprehensible form. Finally, I would like to thank my friends and family on whose support I could always rely. ii TABLE OF CONTENTS Acknowledgements
