This is a substantially re-written and enlarged version of the book From Keynes to Neoclassical Synthesis. It was necessary to re-write and add to that book not just because of the new facts which have come to light since then. The 1970s were marked by a deep crisis of bourgeois economic thought the gist of which was a sharp criticism of the orthodox economics, a re-appraisal of the values, a review of the old theories and a search for new theories of economic development and regulation of the economic mechanism, notably a restructuring of the theoretical paradigm as a whole.
