An empirical analysis of structural forces in refractory metal markets von Dirk Johannes Langhammer Diplom-Wirtschaftsingenieur Promotionsschrift Eingereicht am 19.

I am particularly indebted to my doctoral advisor Prof. Dr. Armin Reller (Augsburg University), whose initial ideas formed the nucleus for this work and whose encouragement and valuable comments were always a driving force throughout the entire process. In addition, Prof. Reller created a thought-breeding environment to explore new frontiers and ways to the theoretical underpinnings of the dynamics in metal markets. Furthermore, I would like to express my earnest appreciation to Dr. Benedikt Zeumer (McKinsey&Company) who brought an inspiring commercial view to the topic and was a key sparring partner always available to discuss new issues and concepts. Dr. Leonhard Birnbaum (RWE AG) and Dr. Thomas Vahlenkamp (McKinsey&Company) were an invaluable force in helping to lay out the initial concept and support for this work and I would like to express my gratitude to both of them. Prof. Dr.
