There is now plenty of evidence that economic growth is highly problematic for human welfare and survival. The evidence comes from three domains. 1) The ecological: continual growth uses up the resources that supply and the sinks that take the waste from human activity globally. 2) The social: economic growth does not correlate well with human welfare and its supposed benefits, rather than being shared, become ever more concentrated at the top of the wealth and income pyramid. 3) The economic: economic systems that rely on perpetual growth are inherently unstable, and meet internal and external constraints (or contradictions) that undermine them.
While it may be clear that the wager on endless growth is a bad one, a more difficult question arises: “what would be the characteristics of an economy that does not grow?”.
In his book “Macroeconomics Without Growth1” Steffen Lange attempts to construct a framework for answering this question, rooted in the three main approaches to theorising the economy, hence the subtitle: “Sustainable Economies in Neoclassical, Keynesian and Marxian Theories”. The book is a valuable contribution to the theory and practice of degrowth and provides a solid grounding for interventions in the policy arena, including those by political parties that seek to construct a coherent alternative, rather than a mishmash wish list of proposals. A strength of the book is its rigorous, formal analysis of the main theoretical approaches and what they say about the preconditions for growth, and the possibilities of zero growth.
As such the book extends to 583 pages, and the detail, with recourse to mathematical formulae to capture the various models and sub-models, will mean that many will not read it. The aim of this essay review, then, is to summarise the book, emphasising the synthesis reached by Lange, and suggesting a few issues that arise.
