Há desigualdade de poder entre os Estados e regiões do Brasil? Uma abordagem utilizando o índice de poder de Banzhaf e a penrose square root Law

Abstract

In Brazil there are always discussions about the number of representatives in the Federal Camera, with indications of sub or super representativeness. This discussion has political and economic value because an amount of the public resources is defined in this body and it can be linked to the effective power of the states, which can be measured by the Banzhaf index. A proposal, suggested by Penrose, is analyzed for Brazilian States and Regions. Application shows that, for the current as for the Penrose system, the most favored region is the Southeast. From the viewpoint of States, it is noticed that are those more developed and populous that possess larger voting power in both situations.
