Stephanie Flanders looks at the life and work of economist John Maynard Keynes, and how his ideas have never been more relevant or controversial than now.

In Masters of Money, produced in partnership with the Open University, BBC economics editor Stephanie Flanders examines how three extraordinary thinkers, Keynes, Hayek and Marx, helped shape the 20th century and continue to exert a huge influence on our world today.

Stephanie begins by looking at John Maynard Keynes. Many argue only Winston Churchill had a greater impact on British life than Keynes over the last century. Even today his ideas remain crucial to one of the most important debates of our time: how can we escape from the economic crisis? Should governments borrow and spend their way out of trouble or slash spending and reduce the national debt?

With contributions from some of the world's leading economic thinkers including a Nobel laureate and the governor of the Bank of England, Stephanie Flanders argues Keynes has never been more relevant or controversial than now.

During his life, Keynes was credited with, amongst other things, helping to save capitalism from the Great Depression, funding the war against the Nazis and building post-war decades of growth and rising prosperity. And when the global crisis struck in 2008, it was his ideas that the world's leaders turned to to help avoid another depression.
