Firm size follows Zipf's Law, a very fat-tailed distribution that implies a few large firms account for a disproportionate share of overall economic activity. This distribution of firm size is crucial for evaluating the welfare impact of economic policies such as barriers to entry or trade...

We consider a tractable model of heterogeneous production units that features endogenous entry and productivity investment to assess the quantitative impact of policy distortions on aggregate output and establishment size. Relative to the standard factor misallocation framework, policy...

In France, firms with 50 employees or more face substantially more regulation than firms with less than 50. As a result, the size distribution of firms is visibly distorted: there are many firms with exactly 49 employees. We model the regulation as the combination of a sunk cost that must be...

The heavy-tailed distribution of firm sizes first discovered by Zipf (1949) is one of the best established empirical facts in economics. We show that it has strong implications for asset pricing. Due to the concentration of the market portfolio when the distribution of the capitalization of...

We provide a new model that generates persistent performance differences amongst seemingly similar enterprises. Our model provides a mechanism whereby efficient incumbent rivals can give permission for an inefficient firm to exist in the presence of efficient entrants. We demonstrate that, in a...

We construct a new dataset for the average employment size of establishments across sectors and countries from hundreds of sources. Establishments are larger in manufacturing than in services, and in each sector they are larger in richer countries. The cross-country income elasticity of...
