Book excerpt: As a whole this book adds the ‘Keynes’-component (K) to the Goodwinian vision of a ‘MKS-System’. It first provides a reconsideration of prominent past approaches towards the formation of Keynesian macrodynamics. Ultimately it aims to integrate Marx's Distributive Cycle and aspects of Schumpeter's reformulation of socialism and democracy theory, with Keynes' macro-theory of a ‘Tripartite Market Hierarchy’. This regards financial markets as being at the top, followed by goods markets which in turn are followed by the weakest element, the labor markets. It is completed by certain repercussions that influence the central causal nexus of these three fundamental macro-markets in the longer-run.
