How can we organize our economies without growth? "Macroeconomics Without Growth' provides a comprehensive understanding of how non-growing economies can be sustainable. With this book, Steffen Lange brings new momentum into the debate on post-growth, degrowth and steady state economies. The book delves deep into economic theory to understand how a macro-economy can operate without growth. By applying a highly diverse set of theories - from Neoclassical, Keynesian and Marxian traditions - the book is able to cover a wide range of macroeconomic aspects: Is zero growth possible in a capitalist economic system? What happens to aggregate demand and aggregate supply when economies stop growing? And what role do firms, markets and technological change play in post-growth economies?
