Essays on Agglomeration and Inter-Jurisdictional Competition Inaugural-Dissertation zur Erlangung des Grades Doctor oeconomiae publicae (Dr. oec. publ.) an der Ludwig-Maximilians-Universität München Volkswirtschaftliche Fakultät im Jahr 2009 vorgelegt von Hyun-Ju Koh Referent: Prof. Dr. Rainald Borck Korreferent: Prof. Dr. Michael Pflüger Promotionsabschlussberatung: 10. Februar 2010 Acknowledgements First I want to thank my supervisor Rainald Borck for his academic guidance and encour- agement. He gave me the freedom to pursue my research interests and was always willing to discuss new ideas and thoughts with me. His comments and suggestions improved every paper of the dissertation. I am also grateful to my second supervisor Michael Pflüger. His fascination for regional and urban economics spilled over and became my favorite research interest. I am also thankful for his efforts to arrange a research stay abroad. I thank Andreas Haufler who completes my thesis committee for valuable comments on my research. I am also indebted to Gilles Duranton who served as a local supervisor during my stay at the University of Toronto. I much enjoyed doing research in such an inspiring environment. I gratefully acknowledge financial and academic support from the Bavarian Graduate Program in Economics and the Elitenetzwerk Bayern. Special thanks go to my co-authors for the rewarding experience that doing research together is much more fun. Part of the chapters were presented at conferences: the meeting of the Austrian Economic Association (NoEG) in Vienna, 2008, the Annual Meeting of the European Economic Asso- ciation (EEA) in Milan, 2008, the IIPF Meeting in Maastricht, 2008, the Public Economic Theory (PET) Meeting in Seoul, 2008 and the Annual Meeting of the German Economic As- sociation (VfS) in Magdeburg, 2009. I thank all participants for their comments. I also thank all seminar participants of the BGPE Workshop, Public Economics Seminar and participants of the Trade Seminar at the University of Toronto for their remarks. Special thanks go to my colleagues at the department: Wolfgang Habla, Ferdinand Mitter- maier, Ines Pelger and Nadine Riedel for enjoyable conversations especially those beyond economics. Wolfgang Habla and Mohammed Mardan for research assistance and Anita Hof- mann for handling all administrative affairs. Most importantly, I am deeply indebted to my family. Their love and support helped me to endure especially difficult times during my years of studies.
