We develop a simple menu-cost model with non-constant elasticity of demand that features idiosyncratic productivity and demand shocks. The model is calibrated to match firm-level productivity and demand processes estimated from U.S. data. Despite its simplicity, the calibrated model delivers...

Unemployment is low and inflation is falling, but consumer sentiment remains depressed. This has confounded economists, who historically rely on these two variables to gauge how consumers feel about the economy. We propose that borrowing costs, which have grown at rates they had not reached in...

We study how US consumers' house price expectations respond to verbal and non-verbal communication about interest rate changes using several large online surveys. Verbal communication about interest rate hikes leads to little response of average house price expectations but large heterogeneity...

In a collaborative project with ten central banks, we have investigated the causes of the post-pandemic global inflation, building on our earlier work for the United States. Globally, as in the United States, pandemic-era inflation was due primarily to supply disruptions and sharp increases in...

We study how within-store price variation changes with inflation, and whether households exploit it to attenuate the inflation burden. We use micro price data for food products sold by 91 large multi-channel retailers in ten countries between 2018 and 2024. Measuring unit prices within narrowly...

This paper explores alternative methods for adjusting price indices for quality change at scale. These methods can be applied to large-scale item-level transactions data that includes information on prices, quantities, and item attributes. The hedonic methods can take into account the changing...

This paper uses machine learning (ML) to estimate hedonic price indices at scale from item-level transaction and product characteristics. The procedure uses state-of-the-art approaches from hedonic econometrics and implements them with a neural network ML approach. Applying the methodology to...

We document how supply-chain pressures, household inflation expectations, and firm pricing power interacted to induce the pandemic-era surge in consumer price inflation in the euro area. Initially, supply-chain pressures increased inflation through a cost-push channel and raised inflation...

This paper assesses the proximate causes of the post pandemic surge in US inflation, the Federal Reserve's real time reaction to and interpretation of incoming data in 2021, and the pivot to raising rates and shrinking the balance sheet that commenced in 2022 and continues in 2023. Particular...

We use equity returns to construct a time-varying measure of the interest rate that we call the zero-beta rate: the expected return of a stock portfolio orthogonal to the stochastic discount factor. The zero-beta rate is high and volatile. In contrast to safe rates, the zero-beta rate fits the...
