It is a pleasure to sit down and thank the many people who have contributed to this study.In particular, I would like to thank several scholars, both Colombian and American, who have shared their knowledge and enthusiasm for such a beautiful and complex country. James Robinson at Harvard University was quite helpful in putting me in contact with colleagues in Colombia, and in thinking about the idea of the frontier. Ana María Ibáñez at Universidad de los Andes in Bogotá was very generous in sharing the recent data on land gini collected by her team in collaboration with the geographic institute IGAC. Andres Zambrano at UCLA was kind enough to put me in contact with several of his colleagues in Colombia, and helped me to secure access to the CEDE-UNIANDES-IGAC data. Oliver Kaplan and Michael Albertus were also very generous, and shared their data on land reform enthusiastically.The Department of Sociology at UCLA, and Los Angeles more generally, have been my home for the past eight years. The research was made possible by fellowships from the Department of Sociology. My dissertation committee at UCLA has provided me with excellent guidance through what seemed at times an insurmountable process. Vilma Ortiz has been a warm and dedicated mentor, and helped me stick to this project when it felt like it was too hard to continue. Gabriel Rossman has provided incisive comments at each stage, and really helped tighten my thinking on networks and hierarchy, as well as broaden the scope theoretically; his breadth of knowledge is amazing. Mark Sawyer was a great outside member, and really helped me engage more with political science and political sociology, deepening my theoretical framework. My chair, César Ayala, has been with me since I began the program at UCLA, and has seen me through each stage of this process. He has provided encouragement and support throughout all of these stages, believing in me even in the periods when I lost focus. I would also x like to thank several of my fellow graduate students, without which I would not have been able to endure this process: in particular, Alex Huezo, Mateo Schoorl, Anthony Alvarez, and Dwight Davis. I am lucky to have found people I can call good friends while in graduate school. This dissertation is dedicated to my family: to my father, Carl, my mother Carmen and my brother Chris. They have provided me with endless love and support through the years, recharging me on trips home to Boulder with outdoor BBQs on our back deck, tennis games with my uncle Gustavo, hikes to Brainard Lake, ski trips to Telluride, trips to Ten Ten Brasserie and to Jax. My father started a program at UCLA in the Department of Geology in the 1970s. He inspired me to become a better thinker and to approach the world with patience and warmth and thoughtfulness. My mother has been my champion (even when she has embarrassed me), and has constantly shown me how to balance graduate school with the arts, and to become a more complete person. My brother has been an inspiration to me ever since we were litt...
