Some of the key economic challenges facing the U.S. include its large federal debt and the possibility of a fiscal crisis, as well as the disruptions (and perhaps promises) of the widespread adoption of Artificial Intelligence. Greg Mankiw discussed these challenges in an EconoFact Ask Me Anything webinar held on October 15, 2025. This EconoFact Chats episode is an abridged recording of that webinar.



Greg is the Robert M. Beren Professor of Economics at Harvard University. He served as the Chair of the Council of Economic Advisers in the George W. Bush administration. He is the author of the bestselling Principles of Economics and Macroeconomics textbooks.
