The economist John Maynard Keynes transformed 20th century economic policy. Considered one of the great minds of his age, his seminal work The General Theory of Employment, Interest and Money, sought to diagnose and find solutions to the misery and mass unemployment of the Great Depression. For decades his ideas were central to economic policy adopted across the western world and have made a comeback after the financial crash of 2008. Alex Last presents rare recordings of Keynes from the BBC archive and speaks to Lord Skidelsky, Emeritus Professor of Political Economy at Warwick University and biographer of Keynes.
