Martin Feldstein is a professor of economics at Harvard University, former president of the National Bureau of Economic Research, and was chairman of the Council of Economic Advisers under President Reagan (1982-1984). In this Conversation, Feldstein discusses the financial crisis of 2008, the policy mistakes that led to it, and the risks we face today from a sustained policy of low interest rates. Feldstein then shares his perspective on other important questions of political economy—including the costs and benefits of trade, the impact of technological innovation, as well as the need for tax and regulatory reform. Finally, Feldstein recalls his experiences as chairman of the Council of Economic Advisers and explains what we can learn from how Reagan managed the serious economic challenges of the early 1980s.
