Custom software is distinct from other types of capital in that it is non-rival—once a firm makes an investment in custom software, it can be used simultaneously across its many establishments. Using confidential US Census data, we document that while firms with more establishments are more...

Why do export sales increasingly concentrate among a few "superstars"? This paper is the first to argue that the expansion of the Internet matters for this phenomenon. Using firm-level customs transaction data from 11 developing countries, we show that the spread of the internet steepens the...

The Pareto distribution has been used to describe firm sizes in many theoretical models for its convenience and empirical validity. We provide estimates of the Pareto parameters across industries and investigate the determinants of the shape of the firm size distribution in Brazil. The Pareto...

What are the pro-competitive consequences of trade in frictional labor markets? This paper develops and estimates a dynamic general equilibrium trade model to show that the interplay between endogenously variable markups in product markets and frictions in labor markets has important...

Using a new panel dataset of about 140 thousand Portuguese firms during 2006-2019, we measure the effects of globalization on firm-level performance along four dimensions: ownership of capital, employment of foreign-seasoned managers, and participation in export and import markets. Once at least...

This paper examines a homogeneous-good Bertrand-Edgeworth oligopoly model to explore the role of firm size and number in pricing. We consider the price impact of merger, break up, investment, divestment, entry and exit. A merger leads to higher prices only when it increases the size of the...

This Brief studies the establishment size distribution in the European Union countries. A well-established literature has established that an abundance of small establishments among lower-income countries is evidence of the misallocation of inputs. To investigate this phenomenon, this Brief...

The current Special Issue brought out the newest trends in Econophysics that have made use of the most recent available tools, such as Big Data. The emphasis of the reprint is on deciphering the effects of current world events, such as the repercussions of the recent war conflicts, the oil and...

In 2011, the EU-South Korea Free Trade Agreement (EUKFTA) entered into force. With its focus on non-tariff barriers (NTBs), it is a leading example of a deep new generation agreement. Using detailed French customs data for the period 2000 to 2016, we investigate how exporters of different size...

How do firms of different sizes react to trade liberalization? Leading theories suggest that, amongst continuing exporters, lower trade costs should boost exports of smaller firms by the same or a greaterrate than those of larger firms. However, studying the entry into force of the ambitious...

Power laws in productivity and firm size are well documented empirical regularities. As they are upper right-tail phenomena, this paper shows that assuming asymptotic power functions for various model primitives (such as demand and firm heterogeneity) are sufficient for matching these...

The size distribution of firms is an important indicator of market concentration. Studying the distribution of sales for eBay’s commercial sellers, this paper provides the first analysis of a firm size distribution (FSD) at an online market, further examining its evolution, and the underlying...

Most of the rise in overall earnings inequality is accounted for by rising between-industry dispersion from about ten percent of 4-digit NAICS industries. These thirty industries are in the tails of the earnings distribution, and are clustered especially in high-paying high-tech and low-paying...

The expansion of enterprise level datasets has led to the emergence of a large body of literature on patterns of employment and job dynamics across different enterprise types. In the context of India, where MSMEs have been traditionally supported and encouraged by different policy initiatives to...

Recent work highlights a falling entry rate of new firms and a rising market share of large firms in the United States. To understand how these changing firm demographics have affected growth, we decompose productivity growth into the firms doing the innovating. We trace how much each firm...

This paper investigates firms’ responses to threshold-dependent intensity of tax enforcement. We use administrative tax return data over the entire population of German firms and exploit industry variation in firm size thresholds applied by the tax administration. In our setting, each...

We show that distortion in the size distribution of banks around regulatory thresholds can be used to identify costs of bank regulation. We build a structural model in which banks can strategically bunch their assets below regulatory thresholds to avoid regulations. The resulting distortion in...

We measure the role of firm heterogeneity in counterfactual predictions of monopolistic competition trade models without parametric restrictions on the distribution of firm fundamentals. We show that two bilateral elasticity functions are sufficient to nonparametrically compute the...

Analyzing data on all U.S. employers in a cohort of entering firms, we document a highly skewed size distribution, such that the largest 5% account for over half of cohort employment at firm birth and more than two-thirds at firm age 7. Little of the size variation is accounted for by industry...
