The severity of the Great Financial Crisis took economists by surprise, particularly the ones who believed that markets were largely stable and self-regulating.

On this week's episode of Odd Lots, we speak with Lord Robert Skidelsky, an economic historian who is known for being the pre-eminent biographer of John Maynard Keynes. Skidelsky is the author of the new book “Money and Government: The Past and Future of Economics”, and he tells us why economists' failure to understand what money is has been so detrimental to their understanding of the world.
