An engaging chapter-by-chapter guide to the most important economics text of the twentieth century John Maynard Keynes’s General Theory of Employment, Interest and Money revolutionized economics. But it can be dense and cryptic, an intimidating work for the uninitiated. This companion volume approaches the argument methodically and with clarity, explaining obscure terms and breaking down Keynes’s ideas and their significance for his time and ours. Award-winning economist and author Geoff Mann allows readers to comprehend why the word “Keynesian” has become so contentious today — and so important.
