The General Theory of Employment, Interest, and Money
by John Maynard Keynes
Keynes profoundly influenced the New Deal and created the basis for classic economic theory. “I can think of no single book that has so changed the conception held by economists as to the working of the capitalist system” —Robert L. Heilbroner.
“The General Theory is nothing less than an epic journey out of intellectual darkness. That, as much as its continuing relevance to economic policy, is what makes it a book for the ages. Read it, and marvel.” —Paul Krugman
