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 …

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 …

Inflation rates across firms have become more dispersed and skewed since the start of … the pandemic. We find that average price inflation is positively correlated with the dispersion and skewness of the …

A key policy question is: How high an inflation rate should central banks target? This depends crucially on the costs … of inflation. An important concern is that high inflation will lead to inefficient price dispersion. Workhorse New … Keynesian models imply that this cost of inflation is very large. An increase in steady state inflation from 0% to 10% yields a …

To examine the first, we look at 122 recessions over the past 50 years … unemployment on inflation, for given expected inflation, decreased until the early 1990s, but has remained roughly stable since …

This paper asks whether a textbook Phillips curve can explain the behavior of core inflation in the euro area. A … critical feature of the analysis is that we measure core inflation with the weighted median of industry inflation rates, which … is less volatile than the common measure of inflation excluding food and energy prices. We find that fluctuations in core …

I estimate …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 …

This paper examines the recent behavior of core inflation in the United States. We specify a simple Phillips curve … based on the assumptions that inflation expectations are fully anchored at the Federal Reserve's target, and that labor …-market slack is captured by the level of short-term unemployment.
