# John Maynard

john maynard Keynes, 1st Baron Keynes ( KAYNZ; 5 June 1883 – 21 April 1946), was a British economist, whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles, and was one of the most influential economists of the 20th century. His ideas are the basis for the school of thought known as Keynesian economics, and its various offshoots.During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands.
