On the methodological plain this paper outlines the conditions that contribute to the development of economic theories and it continues with an examination of the concrete circumstances that gave rise to modern neoclassical macroeconomic theories. The paper further claims that the current impasse in macroeconomics is indicative of the need for new directions in economic theory which becomes imperative in the long economic downturn that started in 2007 and concludes by suggesting the need for a synthesis between the classical analysis and the theory of effective demand.
