Gauti Eggertsson is a professor of economics at Brown University and is the author of several recent papers on the causes of the 2021-22 inflation surge and the lessons to be drawn from it for monetary policy going forward. Gauti is also a returning guest to Macro Musings, and he rejoins the show to talk about these papers and their findings. Specifically, David and Gauti discuss the role of the Fed’s FAIT framework in the post-pandemic inflation surge, the return of the non-linear Phillips curve, the merits of nominal GDP targeting and average nominal output targeting, Gauti’s policy suggestions for the Fed, and a lot more.   Transcript for this week’s episode.   Gauti’s Twitter: @GautiEggertsson Gauti’s website Gauti’s Brown University profile   David Beckworth’s Twitter: @DavidBeckworth Follow us on Twitter: @Macro_Musings   Join the Macro Musings mailing list!
