Darrell West, vice president and director of Governance Studies and author of “Megachange: Economic Disruption, Political Upheaval, and Social Strife in the 21st Century,” analyzes how recent dramatic disruptions in trends, such as the rise of Donald Trump and Brexit, are challenging institutions and societies. Also in this episode, David Wessel, senior fellow and director of the Hutchins Center on Fiscal on Monetary Policy, talks about the types of economic policies that we can expect from a Trump presidency.
