Relativizando o Dilema Estabilidade versus Instabilidade: Keynes, o Mainstream e o Conceito de Bifurcação em Economia

From a methodological perspective, the paper aims to introduce a relativization of the dilemma stability versus unstability in the economic science. Although it was announced by Vercelli (1991), it is not well developed in Economics. While the mainstream regards the economic system as having an exclusively stable nature, Keynes’ General Theory, if not well understood, may take us to a interpretation exclusively unstable of the system. Hence, it’s necessary a complex comprehension of the economic system, that, through concepts as such bifurcation, makes it possible a theory of the historic alteration of phases in Economic Science.Estabilidade, Instabilidade, Mudan¸cas Estruturais, Bifurcação
