We analyze optimal capital and labor taxes in a model where (i) the government makes noncontingent announcements about future policies and (ii) ex-post statecontingent deviations from these announcements are costly. With Full Commitment, optimal fiscal announcements are unbiased forecasts of...

We consider models where the Ramsey-optimal fiscal policy under Full Commitment (FC) is time-inconsistent and define a new notion of optimal policy, Limited-Time Commitment (LTC). Successive one-period lived governments can commit to future plans over a finite horizon. We provide a sufficient...

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...

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....

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...

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,...
