Teoria da inflação: do princípio da demanda efetiva à curva de Phillips com expectativas adaptadas

Abstract

This article is of a pedagogical nature. It makes a review of the evolution of research and economic discussion on the theory of inflation over a large period lasting from keynesian thought up to the point before the advent of the rational expectations "revolution". It centers around the mainstream arguments covering the keynesian theories, the Cost "versus" Demand-pull Inflation discussion, the original Phillips Curve formulation, and the expectations-argumented Phillips Curve which followed the Friedman-Phelps criticisms to the original formulation.
