‘The Supermultiplier is a wonderful and much-needed book. It is wonderful because it is thoughtful, scholarly and well-written and it is much-needed because it takes the ideas, theories and models of the Post-Keynesian movement in today's economics and develops their implications for policy and social development, centring the analysis on the idea of the supermultiplier. The result is an excellent piece of economic writing: highly readable, yet deeply thoughtful.’
