The course will analyze the relationship between federalism and public policies from three perspectives. The first is conceptual, studying the concept of Federation and its impact on public policies, both from a theoretical point of view and from the point of view of comparative international experience. Secondly, the intersection of the federative theme with the construction of a Welfare State in Brazil will be analyzed, starting with the presentation of a broader historical panorama and focusing on the changes that have occurred especially since the 1988 Constitution. Finally, some specific government sectors will be discussed, such as Education, Health, Social Assistance and the Environment, among the main ones, to show how intergovernmental dynamics are a key element in understanding the functioning and results of Brazilian Public Administration.
