Ioweanimmensedebtofgratitudetomymainadvisor,DavidWeil,andmythesis committee members, Pedro Dal B´o,Stelios Michalopoulos, and Brian Knight. I am particularly grateful to David. His advice, guidance, support, and mentorship during my years at Brown were crucial for my professional development. David is not only one of the smartest scholars I have ever met but also a great human being. I would certainly be remiss in failing to acknowledge the key role played by Pedro in making my journey at Brown possible. He was not only instrumental in bringing me to Brown University but also in making me feel that my lovely Argentina was actually not that far. With his scientific meticulousness, Pedro also taught me how to think outside the box. Brian and Stelios had nurtured my intellectual development by generously providing their time, invaluable comments, and unwavering guidance. I would also like to take this opportunity to thank Oded Galor who was always willing to help. I appreciate the fact that his office door was always open whenever I needed advice. Many thanks also go to Peter Howitt, Vernon Henderson, Ken Chay, Louis Put- terman and Blaise Melly for comments, help, and advice in di↵erent stages of my graduate studies. I thank Juan Carlos Hallak, Daniel Heymann, and Walter Sosa Es- cudero for their invaluable support, help, and mentoring in the transition to my Phd studies at Brown University.

Her kindness and hilarious sense of humor is something that I will certainly miss.
