I would like to thank my advisor, Luciano Nakabashi, for his support in my thesis work, for his valuable macroeconomics lessons and for his guidance during all the research we did together. Our partnership over the five years of my doctorate was very successful and gave me a lot of learning. I also want to express my gratitude to my co-supervisor, Fernando Barros Jr, for his support and commitment to the papers we produced together. Our weekly meetings have always been very productive and have added a lot of knowledge to me. I am also very grateful to Fernando Barros Jr for having the patience to teach me how to work with computable general equilibrium models. I extend my thanks to Professor Bruno Delalibera for his support, particularly in the third paper of this thesis, and for sharing insights about professional and academic life. The dedication, hard work, patience, and professional journey of these three economists will always be a source of inspiration for me.I would like to thank the members of the committee, Maurício Bittencourt, Luiz Brotherhood, Tomás Martinez, and Pedro Cavalcanti, for their valuable contributions to our research. I am grateful to Professors Fábio Gomes and Luiz Brotherhood for their conversations and insights during the initial phase of my thesis project. I also appreciate the teachings of Professor Jefferson Bertolai, who instilled in us the importance of rigor in our work. I would also like to express my gratitude to the professors at FEARP, Márcio Poletti Laurini, Sérgio Kannebley Júnior, Fábio Barbieri and Sergio Naruhiko Sakurai, for the knowledge imparted during my doctoral studies, which has been incredibly valuable. Finally, I would also like to thank the staff at the department, particularly Selma Lúcia Rocha Pontes and Érika de Lima Veronezi Costa for their support.
