We study the potency of sectoral productivity shocks to drive aggregate fluctuations in the presence of three empirically relevant heterogeneities across sectors: sector size, intermediate input consumption, and pricing frictions in a multi-sector New Keynesian model. We derive conditions under...

We study the ability of sectoral shocks to generate aggregate fluctuations in a multi-sector general equilibrium model featuring sectoral heterogeneity in price stickiness, sector size, and input-output linkages. We show fat-tailed distributions of sectoral size or network centrality are neither...

We document a novel role of heterogeneity in price rigidity: It strongly amplifies the capacity of idiosyncratic shocks to drive aggregate fluctuations. Heterogeneity in price rigidity also completely changes the identity of sectors from which fluctuations originate. We show these results both...

We study the aggregate implications of sectoral shocks in a multi-sector New Keynesian model featuring sectoral heterogeneity in price stickiness, sector size, and input-output linkages. We calibrate a 341 sector version of the model to the United States. Both theoretically and empirically,...

Realistic heterogeneity in price rigidity interacts with heterogeneity in sectoral size and input-output linkages in the transmission of monetary policy shocks. Quantitatively, heterogeneity in price stickiness is the central driver for real effects. Input-output linkages and consumption shares...

This paper introduces a novel measure of consumer inflation expectations: We elicit and combine inflation forecasts across categories of personal consumption expenditure to form an aggregated measure of inflation expectations. Drawing on answers from nearly 60,000 respondents, our data cover the...
