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 …

To what extent is the recent spike in inflation driven by a change in its permanent component? We estimate a semi …-structural model of output, inflation, and the nominal interest rate in the United States over the period 1900-2021. The model predicts … that between 2019 and 2021 the permanent component of inflation rose by 51 basis points. If instead we estimate the model …

expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real … shocks and higher investment in response to government spending. Sticky discount rates imply that inflation has real effects … inflation expectations and permanently lowers the long-run inflation target in response to expansionary shocks, even when shocks …

. The model delivers a static wage Phillips curve linking current wage inflation to current unemployment. For standard … stickiness, which features a forward-looking wage Phillips curve, linking current wage inflation to future expected wage … inflation and current unemployment. This result puts in perspective the role played by the forward-looking component of the new …

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 …

of inflation from different periods, which have become more prevalent as inflation has risen to 40-year highs. To better … contextualize the current run-up in inflation, this paper constructs new historical series for CPI headline and core inflation that … that current inflation levels are much closer to past inflation peaks than the official series would suggest. In particular …

This paper first outlines the key stylized facts about changes in inflation dynamics in recent years: 1) inflation … persistence has declined, 2) the Phillips curve has flattened, and 3) inflation has become less responsive to other shocks. These … changes in inflation dynamics are interpreted as resulting from an anchoring of inflation expectations as a result of better …

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 …

Sticky-price models with rational expectations fail to capture the inertia in U.S. inflation. Models with backward …-looking expectations capture current inflation behavior, but are unlikely to fit other monetary regimes. This paper seeks to overcome these … problems with a near-rational model of expectations. In the model, agents make univariate forecasts of inflation: they use …
