In this dissertation, we analyze some patterns of aggregate job reallocation that are significantly determined by the coexistence of heterogeneous businesses in any industry. First, we argue that the interaction of non-strictly convex adjustment costs and learning about true efficiency can...

This paper studies the behavior of producers of capital goods, examining how they set shipments in response to fluctuations in new orders. The paper establishes a stylized fact: the response of shipments to orders is more pronounced when the level of new orders is low relative to the level of...

We propose a measure for the importance of aggregate shocks for fluctuations in job flows at the firm level. Using data for the Portuguese economy, we find that large and old firms exhibit higher relative sensitivity to aggregate shocks and have a disproportional influence over the dynamics of...

We propose an explanation for the rapid post-entry growth of surviving firms found in recent studies. At the core of our theory is the interaction between adjustment costs and learning by entering firms about their efficiency. We show that linear adjustment costs, i.e., proportional costs,...

After having been a relatively bright spot early in the recovery, nonresidential private fixed investment, which in this note we refer to as business fixed investment (BFI), increased at an average annual rate of only about 4 percent in 2012 and 2013, an unusually slow pace during an expansion
