The refinements of the orthodox macroeconomic theory and the post keynesian theory : bringing back the debate between keynes and classicals

Abstract

O artigo, à luz da teoria pós-keynesiana, objetiva mostrar que a teoria macroeconômica ortodoxa, mainstream, apesar de seu refinamento teórico, é inconsistente com as características das modernas economias empresariais e, por conseguinte, não consegue explicar a dinâmica do mundo real. O artigo, ainda, sinaliza que o atual debate macroeconômico entre mainstream e pós-l<eynesianos é uma extensão do debate entre Keynes e os economistas clássicos, então observado há mais de sessenta anos.

In the light of post Keynesian theory, the articles aims at showing that the principal theoretical questions and results of new classical models and new Keynesian models are inconsistent with the basic characteristics of modern entrepreneurial economies and, as a consequence, they cannot help us to understand the dynamic process of the real world. Besides, it shows that the present debate between post Keynesians and mainstream economists brings back an old discussion between Keynes and classical economists.
