I must first acknowledge the mentorship my two wonderful supervisors, Peter Hedström and Maria Brandén, gave me throughout my PhD education. Peter, your curiosity with a touch of skepticism every time you gave feedback on my writing made this dissertation a much better version of what it would become otherwise. I am forever grateful for your mentorship, your attention and backing whenever I needed. Maria, I am not sure if a few sentences can sum up how grateful I am for all you've done. Whatever I write here will fall short of how important you've been in my life since I've met you. I wholeheartedly believe that I became a better researcher and a better human being with your support throughout these years. Your mentorship, your confidence in me, all the advice you gave about navigating in academia, and countless and always constructive feedback you gave on my drafts are some of the reasons that this dissertation is now finished. Thank you both for keeping me on track but also giving me the space to explore my own ideas.At the Institute, I had the opportunity to study and work alongside many creative and supportive scholars. Sarah Valdez, I am one of the luckiest to have you as a friend and as a colleague since the first days of IAS. Your unwavering support, encouragement, and insightful suggestions throughout these years were monumentally important for me. Now that this journey is over, I am looking forward to the future to party one day like it's 3012. Marc Keuschnigg, I cannot overestimate your help for showing that you always believed in my abilities as a researcher. You have been a colleague that I can turn to whenever I needed advice, and your guidance has been a great help for this dissertation and for my career. Karl Wennberg, I am grateful for all your feedback on v III. Mutgan, Selcan and Eduardo Tapia (2021). "School Closure as a Desegregation Policy: A comprehensive evaluation". Unpublished manuscript.
