When employers face a trade-off between growing large and paying low wages—that is, when they have monopsony power—some productive employers will decide to acquire fewer customers, forgo sales, and remain small. These decisions have adverse consequences for aggregate labor productivity....

When employers face a trade-off between growing large and paying low wages that is, when they have monopsony power some productive employers will decide to acquire fewer customers, forgo sales, and remain small. These decisions have adverse consequences for aggregate labor productivity. Using...

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 heterogeneous-firm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

We study the relationship between cyclical job and worker flows at the plant level using a new data set spanning from 1976-2006. We find that procyclical labor demand explains relatively little of procyclical worker flows. Instead, all plants in the employment growth distribution increase their...

This paper examines how households adjusted their consumption behavior in response to COVID-19 infection risk during the early phase of the pandemic. We use a monthly consumption survey specifically designed by the German Statistical Office covering the second wave of COVID-19 infections from...

Are fluctuations in firms' profitability risk a major cause of regular business cycles? We study this question within the framework of a heterogeneous-firm dynamic stochastic general equilibrium model with fixed capital adjustment costs. In such a model, surprise increases of risk lead to a...

We document a new business cycle fact: the cross-sectional standard deviation of firm-level investment (investment dispersion) is robustly and significantly procyclical. This makes investment dispersion different from the dispersion of productivity and output growth, which is countercyclical....
