We study the relation between inflation and real activity over the business cycle. We employ a Trend-Cycle VAR model to … control for low-frequency movements in inflation, unemployment, and growth that are pervasive in the post-WWII period. We show … that cyclical fluctuations of inflation are related to cyclical movements in real activity and unemployment, in line with …

The US and other advanced countries suffered bursts of severe inflation in 2021 and the first half of 2022, followed by … declines of inflation later in 2022, in some countries. In times of high volatility of price determinants--cost and … productivity--inflation can jump upward and fall downward at high speed, contrary to the uniformly sticky behavior associated with …

We show that, in a broad class of menu cost models, the dynamics of aggregate inflation in response to arbitrary shocks …

explaining bouts of inflation. We begin by showing that a quasi-flat Phillips curve, which was popular prior to the pandemic …, still fits the post-2020 US data well and that changes in short term inflation expectations induced by supply shocks likely … played a major role in the recent inflation episode. We then document features of the joint dynamics of inflation and …

This paper provides an explanation for the run-up of U.S. inflation in the 1960s and 1970s and the sharp disinflation … by low inflation. However, prolonged episodes of high inflation ending with rapid disinflations can occur when … policymakers underestimate both the natural rate of unemployment and the persistence of inflation in the Phillips curve. I estimate …

Our current inflation stemmed from a fiscal shock. The Fed is slow to react. Why? Will the Fed's slow reaction spur … more inflation? I write a simple model that encompasses the Fed's mild projections and its slow reaction, and traditional … views that inflation will surge without swift rate rises.
