Marx, Keynes e Lucas: distinções e afinidades

Abstract

This paper discusses three revolutionary economists, creators or reformists, from different schools of economy. Pointing out the differences between them, from a criterion to make such a comparison possible, this text makes the important distinction between “monetary economy” and “capitalist economy”, not only that, it shows the incompatibility of the ‘rational expectations’ and the Keynesian ‘uncertainty’. Seeking the elements that can approximate the distinguish authors, this paper could find some theoretical features of Keynes that move closer to the neoclassical school.
