The authors describe how evidence on aggregate job flows challenges standard business cycle theory and discuss recent developments in business cycle theory aimed at accounting for the evidence.

We provide a simple explanation for the observation that the variance of job destruction is greater than the variance of job creation: job creation is costlier at the margin than job destruction. As Caballero [2] has argued, asymmetric employment adjustment costs at the establishment level need...

We provide a simple explanation for the observation that the variance of job destruction is greater than the variance of job creation. In our model profit maximization in the presence of proportional plant-level costs of job creation and destruction implies that shrinking plants are more...

There are significant differences in the dynamics of employment over the business cycle between young and old manufacturing plants. Young plants are more sensitive to aggregate disturbances, and they respond to them along different margins. We interpret these differences as reflecting greater...

This paper studies how producers’ idiosyncratic risks affect an industry’s aggregate dynamics in an environment where certainty equivalence fails. In the model, producers can place workers in two types of jobs, organized and temporary. Workers are less productive in temporary jobs, but...
