We show how size-contingent laws can be used to identify the equilibrium and welfare effects of labor regulation. Our framework incorporates such regulations into the Lucas (1978) model and applies this to France where many labor laws start to bind on firms with exactly 50 or more employees....

In the large literature on firm performance, economists have given little attention to entrepreneurs. We use deaths of more than 500 entrepreneurs as a source of exogenous variation, and ask whether this variation can explain shifts in firm performance. Using longitudinal data, we find large and...

We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the...

This paper provides evidence that learning about demand is an important driver of firms' dynamics. We present a simple model with Bayesian learning in which firms are uncertain about their idiosyncratic demand parameter in each of the markets they serve, and update their beliefs as noisy...

We study the implications of ownership and its induced incentives on firm performance in the ‘New Economy’. Instead of traditional performance we use firm survival on the stock market as the performance indicator. Using a unique data set of all 341 firms listed on the Neuer Markt, the German...

After deregulation in 1980, competitive pressures forced the large U.S. freight railroads to restructure. Much attention has focused on defensive (cost-cutting) restructuring: until 2004 employment was reduced by 60%, and railroads abandoned many of their lines. Less attention has been given to...

What is the effect of imports on productivity? To answer this question, we estimate a structural model of producers using product-level import data for a panel of Hungarian manufacturing firms from 1992 to 2001. In our model with heterogenous firms, producers choose to import or purchase...

The German potable water supply industry is regarded as being highly fragmented, thus inhibiting high potentials for efficiency improvements through consolidation. Focusing on a hypothetical restructuring of the industry, we apply Data Envelopment Analysis (DEA) to analyze the potential...

We generalize Krugman's (1979) 'new trade' model by allowing for an explicit production chain in which a range of tasks is performed sequentially by a number of specialized teams. We demonstrate that an increase in market size induces a deeper division of labor among these teams which leads to...

Firm turnover and growth recorded in administrative data sets differ from underlying firm dynamics. By tracing the employment history of the workforce of new and disappearing administrative firm identifiers, we can accurately identify de novo entrants and true economic exits, even when firms...
