In a new article in Foreign Affairs, 'The New Economic Geography: Who Profits in a Post-American World?,' Adam Posen, the President of the Peterson Institute for International Economics, argues that the policies and institutions the US has helped put in place over the past eight decades have not only bolstered its own economic fortunes, but have helped much of the world thrive. Adam joins EconoFact Chats to discuss the article, and point out how the Trump administration's pursuit of an America first policy could render the US, and much of the world, less economically stable. He also discusses who might benefit from America's retreat from global leadership.
