By Atif Mian, Ludwig Straub, and Amir Sufi

òòò½Íø Review, December 2025

We develop a tractable framework for deficit and debt dynamics. A "free lunch" fiscal deficit—one that raises spending without higher future taxes—is sustainable without zero lower bound (ZLB) only when R < G − φ, where φ is the sensitivity of the...
