This timely book presents a nuanced investigation into the idiosyncrasies of the supermultiplier model, examining its application to residential investment, exports and fiscal policy. It offers an accessible introduction to this growth model, hypothesising that it is one of the cornerstones of modern macroeconomics.

By highlighting what this unique model adds to other heterodox systems that share common elements, such as structural growth models, this insightful book strengthens the current theoretical understanding of new macroeconomics. Utilising important case studies such as open and decarbonised economies to encapsulate key messages gained from the study of this model, it fully acknowledges that the supermultiplier is still a work in progress and may be developed further.

The Supermultiplier will be hugely influential for finance and economics graduate students focusing on an alternative macroeconomics approach. It will also appeal to academics within the same fields searching for a model that permits direct application within spreadsheets.
Critical Acclaim
‘The Superrmultiplier 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, centering the analysis on the idea of the supermultiplier. The result is an excellent piece of economic writing: highly readable, yet deeply thoughtful.’
– Edward J. Nell, The New School, US

‘This is an excellent book that offers a new perspective on macroeconomics by utilizing the theoretical tools of modern contributions based on the surplus approach. Dejuán admirably and didactically links various topics around the supermultiplier as a unifying concept to capture the permanent state of things. Therefore, this book is indispensable for understanding the current economy and tackling economic policy.’
– Josep M. Bricall, University of Barcelona, Spain

‘Finally, a thorough discussion on the supermultiplier has arrived. This is an important book that examines many aspects of the supermultiplier. It is a well-researched, well-documented and well-written book, arriving at a time when the topic is gaining prominence across all heterodox approaches. Indeed, all heterodox economists will find much to agree with in this book, which potentially can unite many heterodox voices. It deserves to be in the hands of all those interested in the future development of heterodox economics.’
– Louis-Philippe Rochon, Laurentian University, Canada
