Standard (S,s) models of lumpy investment allow us to match many aspects of the micro data, but it is well known that the implied interest rate sensitivity of investment is unrealistically large. The monetary transmission mechanism is therefore a particularly clean experiment to assess the...

Price setting has become more flexible following a string of large adverse shocks (Covid-19, the Ukraine War). We argue that a shift to a high-uncertainty regime incentivizes firms to invest in their ability to adjust prices. We formalize this idea in a general equilibrium model with endogenous...

Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneousfirm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

Using a unique German firm-level data set, this paper is the first to jointly study the cyclical properties of the cross-sections of firm-level real value added and Solow residual innovations, as well as capital and employment adjustment. We find two new business cycle facts: 1) The...

This paper studies the role of sticky prices for the monetary transmission mechanism, using disaggregated industry-level data from 205 US industries. There is substantial heterogeneity in the output responses of industries to monetary policy surprises. I show that an industry's response to...

Staggered nominal price setting introduces predictable sales variations at the firm level. We study the implications of staggered prices in a framework where, because of increasing marginal cost, firms use inventories to smooth production and thereby separate sales from production. Conventional...

This paper compares the welfare effects of anticipated and unanticipated cost-push shocks in the canonical New Keynesian model with optimal monetary policy. We find that, for empirically plausible degrees of nominal rigidity, the anticipation of a future cost-push shock leads to a higher welfare...
