Nationalist economic policies, including rising opposition to free trade, skepticism of international institutions, and anti-immigrant sentiment, are on the rise at a time when the pandemic and climate change are making international cooperation more necessary than ever. This week on EconoFact Chats, Michael Klein speaks with Maurice Obstfeld, widely recognized as one of the world's leading experts in international economics, on the tensions between globalization and economic nationalism – the historical context, current challenges, and the prospects for the future. Maury Obstfeld is Professor of Economics at U.C. Berkeley. He formerly served as Chief Economist of the International Monetary Fund, and as a Member of the Council of Economic Advisors.
