John Maynard Keynes 
The General Theory of Employment, Interest, and Money 

The General Theory of Employment, Interest, and Money, written by legendary author John Maynard Keynes is widely considered to be one of the top 100 greatest books of all time. This masterpiece was published right after the Great Depression. It sought to bring about a revolution, commonly referred to as the ‘Keynesian Revolution’, in the way economists thought—especially challenging the proposition that a market economy tends naturally to restore itself to full employment on its own. Regarded widely as the cornerstone of Keynesian thought, this book challenged the established classical economics and introduced new concepts.
‘The General Theory of Employment, Interest, and Money’ transformed economics and changed the face of modern macroeconomics. Keynes’ argument is based on the idea that the level of employment is not determined by the price of labour, but by the spending of money. It gave way to an entirely new approach where employment, inflation and the market economy are concerned.

About the Author:
John Maynard Keynes (5 June 1883–21 April 1946), was an English economist whose ideas fundamentally changed the theory and practice of modern macroeconomics and the economic policies of governments. He built on and greatly refined earlier work on the causes of business cycles, and is widely considered to be one of the most influential economists of the 20th century and the founder of modern macroeconomics. His ideas are the basis for the school of thought known as Keynesian economics and its various offshoots.
