Common and Idiosyncratic Inflation
We disentangle price changes due to economy‐wide shocks from those driven by idiosyncratic shocks by estimating a two‐regime dynamic factor model with dynamic loadings on a new large dataset of finely disaggregated monthly personal consumption expenditures price inflation indexes from 1959 through 2024. We find that up to the mid‐1990s and after the COVID‐19 pandemic, common shocks were the primary driver of US inflation dynamics and had long‐las…
The role of observed and unobserved heterogeneity in the duration of unemployment
This paper studies the degree to which observable and unobservable worker characteristics account for the variation in the aggregate duration of unemployment. I model the distribution of unobserved worker heterogeneity as time varying to capture the interaction of latent attributes with changes in labor‐market conditions. Unobserved heterogeneity is the main explanation for the duration dependence of unemployment hazards. Both cyclical and low‐fr…
Heterogeneity and Unemployment Dynamics
Many previous articles have studied the contribution of inflows and outflows to the cyclical variation in unemployment, but ignored the critical role of unobserved heterogeneity across workers. This article develops new estimates of unemployment inflows and outflows that allow for unobserved heterogeneity as well as direct effects of unemployment duration on unemployment-exit probabilities. With this approach, we can measure the contribution of d…
