Olivier Blanchard on debt: “Relax. Don’t relax too much, but relax”

Author of the standard textbook on macroeconomics, former head of research for the International Monetary Fund, currently at the Peterson Institute for International Economics, Olivier Blanchard works in the place where economists and politicians attempt to talk to each other. He talked to us about how the financial crisis changed his thinking on models, why state debt isn’t always and everywhere a bad thing and why the best forecasts in the future might come from artificial intelligence.
