Our guest this week is Princeton University economics professor Atif Mian. He will discuss his new research on how much fiscal space the United States has and whether it can rely on low interest rates and economic growth—rather than higher taxes or spending cuts—to manage its debt.

This interview is part of the Urban-Brookings Tax Policy Center series of online conversations on tax and fiscal policy in today’s economy. The discussions take place every other Thursday afternoon and feature varying perspectives on the historic economic challenges facing the United States and the world and the best ways to address them.
