I also wish to thank Prof. Dr. Thomas Dyllick, the co-advisor of my dissertation. His intellec- tual capacity always enabled him to provide constructive feedback and orientation, which he always presented in a very friendly manner. And whenever I myself had doubts about any particular weakness in my dissertation, I could be sure he had already identified it. Finally, my thanks go to Prof. Dr. Christoph Lechner who – without having a formal role in my dis- sertation – never hesitated to challenge my thoughts and provide helpful feedback. I further thank the Institute of Management, the University of St. Gallen and.
