ETH No. 24020 Labor Income Taxation in a Globalizing World: 1980-2012 A thesis submitted to attain the degree of Doctor of Sciences of ETH Zurich (Dr. sc. ETH Zurich) presented by NORA MARGOT STRECKER Master of Arts in Economics New York University, Graduate School of Arts and Science born on July 29, 1986 citizen of Germany accepted on the recommendation of Professor Peter H. Egger, ETH Zurich, examiner Professor Georg Wamser, University of T¨ubingen,co-examiner 2017 Acknowledgments Words can hardly express the debt of gratitude I owe Professor Peter Egger for giving me the opportunity to work with him and his team at the Chair of Applied Economics: Innovation and Internationalization at ETH Zurich and to complete this dissertation. The research environment at his Chair has produced wonderful interactions, fostered great relationships with my co-authors and colleagues, and greatly advanced both my work and my research. I also gratefully acknowledge the financial support of the Swiss National Science Foundation. I also want to thank my thesis committee, Professors Georg Wamser of the University of T¨ubin- gen and Marko K¨othenb¨urgerof ETH Zurich, for taking the time to read and comment on the dissertation presented here. Of those who have taught me over the years, two stand out in particular. I thank Professor T. Clark Durant for supporting me during my Master's degree at New York University. His courses and seminars allowed me to pursue wild ideas, led me to my first academic conference, and planted the idea of pursuing the even wilder idea of completing a PhD. I am also forever indebted to Marc Vincenti, who, in class and later via his wonderful letters, has continually expressed his unwavering support of me and my goals. His encouraging words were beacons in the dark times of my life, guiding me to where I am today. And for that I can never repay him. I thank my co-authors Simon B¨osenberg, Peter Egger, Sergey Nigai, Doina Radulescu, and Benedikt Rydzek for their efforts on behalf of our joint work and, along with Marie Poprawe, Michaela Kesina, Katharina Erhardt, Andrea Lassmann, Federica Liberini, Michael Stimmelmayr, and the many other current and former colleagues at the Chair for Applied Economics and the Chair for Public Economics at ETH Zurich, for the numerous discussions, the exchange of ideas, and the supportive and motivating environment they've created. This work has been a lengthy labor of love and for their patience I truly thank my friends, who have endured my absence at parties and lack of visits without complaint. For 17 years, Caroline Hintermann's friendship has given me the endurance to work through difficulties and been a light in my life. For fewer but by no means less important years, Polina Minkovski has believed in me, encouraged me, and been my cheerleader. Transitioning from challenging me to think outside i the box in class to think of the big picture outside of it, Polina has been my sounding board and wide-angle lens and invaluable addition to my life and my work. The patience and wholehearted love of my family, Annegret and Achim, Norbert and Ako, and my brother, Alexander, has been the source of great support and encouragement to pursue my goals and overcome our shared hardships. I thank them for their faith in me and my ambitions. Without them I would not be who I am or where I am today.
