My work on inflation has included research on inflation forecasting and structural models of the Phillips curve, including:
Unobserved components models of inflation and the interaction of wages and prices. (slides)
Changes over time in the reduced form Phillips curve and the role of regional variation.
Early work on the New-Keynesian Phillips curve, including the role of sticky prices and sticky information and implications for economic stability.
The graphs below show
Measures of wage and price inflation, related to work on inflation forecasting (e.g., unobserved components models).
Alternative measures of underlying inflation, related to work on inflation forecasting (e.g., unobserved components models).
The Phillips curve in the two decades up to 2019 and then through 2024, suggesting the Phillips curve is back post 2019.
