Central banks responded to the COVID-19 pandemic with large-scale purchases of bonds, commercial paper, and other financial assets.

And when? Join Steven Davis and guest Kathryn Dominguez as they discuss these issues and consider the wisdom of “open-endedness” in central bank policy pronouncements.
