The NBER’s 35th Annual Conference on Macroeconomics brought together leading scholars to present, discuss, and debate six research papers on central issues in contemporary macroeconomics. In addition, Jeremy Stein, former governor of the Federal Reserve, led a thoughtprovoking discussion on whether the financial system is safer now than it was prior to the Great Recession. Given the pandemic, the conference took place via Zoom. Video recordings of the presentations of the papers and the after-dinner talk are all accessible on the web page of the NBER AnnualConference onMacroeconomics.

This conference volume contains edited versions of the six papers presented at the conference. With one exception, each paper is followed by two written discussions by leading scholars and a summary of the debates that followed each paper.
