We characterize the dispersion of firm-level productivity and demand shocks over the business cycle using Swedish microdata including prices and analyse the consequences for firms and the aggregate economy. Demand dispersion increases by more than productivity dispersion in recessions....

This paper develops and estimates a fully microfounded equilibrium business cycle model of the US labor market with aggregate productivity shocks. Those microfoundations are consistent with evidence regarding the underlying distribution of firm growth rates across firms [by age and size] and,...

Firms' sensitivities to business cycles differ by size and age. The differences are large: "young and small firms" are more cyclical than large firms, whereas "old and small" firms are closer to acyclical. A heterogeneous-firm model with heterogeneous returns to scale can replicate these...

We characterize the dispersion of firm-level productivity and demand shocks using Swedish microdata including prices and utilization and analyse the consequences for firms and the aggregate economy. Demand dispersion increases by more than TFPQ dispersion in recessions. Productivity shocks pass...

Capital reallocation is procyclical in the data, but countercyclical in standard business-cycle models. To solve this puzzle, I build a model of endogenous partial irreversibility, with heterogeneous firms facing aggregate and idiosyncratic productivity shocks. Used investment goods are...
