The global financial crisis is largely behind us, but it left challenges it posed to the stability of the world's financial system, to the well-being of families all over the globe and to the academic consensus on the way the economy works.? To describe those challenges and the lessons learned, the Hutchins Center on Fiscal and Monetary Policy at the Brookings Institution turned to front-line policymakers and some of their most prominent critics. This volume provides the papers the Hutchins Center commissioned on unconventional monetary policy, on financial regulation, on the impact of the crisis on the independence of the Fed and transcripts of a lively discussion of those issues.? It also includes an interview with Ben Bernanke, then in his final weeks at Fed chairman, by Liaquat Ahamed, author of the Pultizer-Prize winning "Lords of Finance.""
