The Brazilian lag in the Sarney and Collor government, the planning for monetary stabilization, the resumption of growth of the Brazilian economy, the conquest of democracy and its repercussion are the facts presented in the chapters of Professor Argemiro Jacob Brum's Brazilian Economic Development. We made this presentation with the purpose of demonstrating the elements described above and in which we are responsible for representing this subject in a specific way for the discipline of Contemporary Brazilian Economy in the course of International Relations. Good reading to all, I hope you like it!
