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

Resumo

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.
