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...

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. In our model profit maximization in the presence of proportional plant-level costs of job creation and destruction implies that shrinking plants are more...

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...

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...

We construct a dynamic general equilibrium model of cities and use it to estimate the effect of local agglomeration on per capita consumption growth. Agglomeration affects growth through the density of economic activity: higher production per unit of land raises local productivity. Firms take...

This paper combines impatience with large recurring expenditures to replicate the observation that middle-class U.S. households consume much more out of transitory income than permanent income theory predicts. In the present model, households make a large recurring expenditure of exogenous...

This appendix provides a detailed exposition of the computational method applied to the model of Campbell (1997). Heterogeneity in the production sector of that model implies that its prices and quantities are contnuous functions on the real line rather than scalars. The computational method...

This paper considers the effects of a monopolist raising the cost of entry for potential competitors on Markov-perfect industry dynamics. All entrants serving the model industry incur sunk costs, which they partially recover when exiting. Empirically, the probability of exit declines with the...
