WITGT21 Interviews

The mission of this interview series is to talk to elite economists and ask them what is their views on the evolutions of macroeconomics since the Great Recession. We would introduce some of the new macroeconomics ideas which top economists are pondering in the last ten years. Hopefully, this should give us a good survey on how much macroeconomics, as a science, as the basis of policy tools, has improved (or worsened) since 2008.

What have economists learned from the Great Recession? What else can we try? Does Inequality have a role in Macro of the 21st Century? Does Debt have a role in Marco of the 21st Century? Does Politics have a role in Macro of the 21st Century?
