Recent economic and financial crises have exposed mainstream economics to severe criticism, bringing present research and teaching styles into question. Building on a solid and vivid tradition of economic thought, this book challenges conventional thinking in the field of economics. The authors turn to the work of Luigi Pasinetti, who proposed a list of nine methodological and theoretical ideas that characterize the Classical Keynesian School. Drawing inspiration from both Keynes and Sraffa, this school has forged a long-standing and ambitious research programme often advocated as a competing paradigm to mainstream economics. Overall, the Classical Keynesian School provides a comprehensive analytical framework into which most non-mainstream schools of thought can be integrated. In this collection, a group of leading scholars critically assess the nine main ideas that, in Pasinetti's view, characterize the Classical-Keynesian approach, evaluating their relevance for both the history of economics and for present economic research.
