Tempting FAIT: Flexible Average Inflation Targeting and the Post-COVID U.S. Inflation Surge

In August 2020, the Federal Reserve replaced Flexible Inflation Targeting (FIT) with Flexible Average Inflation Targeting (FAIT), introducing make-up strategies that allow inflation to temporarily exceed the 2% target. Using a synthetic control approach, this paper estimates that FAIT raised CPI inflation by about 1 percentage point and core CPI inflation by 0.5 percentage points, suggesting a moderate impact net of food and energy and a largely temporary effect. The findings are consistent with the hypothesis of a steeper-than-expected post-pandemic Phillips curve in the New Keynesian model.
