What is Firm Growth Rates and Distributions?
Firm growth rates and distributions analyze empirical patterns of firm size changes, testing Gibrat's law and Laplace distributions across industries and time periods.
Researchers examine scaling properties and selection effects in firm growth data. Studies use micro-level datasets to test whether growth rates are independent of firm size as per Gibrat's law (1931). Over 10,000 papers cite related foundational works like Melitz (2002) with 3056 citations.
Why It Matters
Firm growth distributions reveal selection mechanisms driving aggregate productivity, as trade exposes heterogeneous firms leading to resource reallocation toward high-productivity ones (Melitz, 2002). Misallocation in growth rates explains TFP gaps in China and India versus the U.S. (Hsieh and Klenow, 2007). Insights guide industrial policy by identifying barriers to scaling for innovative firms (Brandt, Van Biesebroeck, and Zhang, 2011).
Key Research Challenges
Testing Gibrat's Law Empirically
Gibrat's law posits size-independent growth rates, but selection effects bias estimates in survivor samples. Empirical tests require longitudinal microdata to separate true growth from exit risks (Melitz, 2002). Citation distributions show heavy tails challenging random growth models.
Modeling Heavy-Tailed Distributions
Firm growth rates follow Laplace distributions with fat tails, not normal distributions. Identifying scaling exponents demands large datasets amid noise from measurement error (Hsieh and Klenow, 2007). Industry heterogeneity complicates universal parameter estimation.
Quantifying Misallocation Effects
Resource misallocation distorts growth distributions and lowers aggregate TFP. Firm-level data from China reveals dispersion in marginal products driving productivity losses (Brandt, Van Biesebroeck, and Zhang, 2011). Isolating policy distortions from technological heterogeneity remains difficult.

Frequently Asked Questions
What is Gibrat's law in firm growth?
Gibrat's law states firm growth rates are independent of initial size, implying log-normal size distributions. Empirical rejections show Laplace distributions due to selection (Melitz, 2002).
What methods test firm growth distributions?
Methods include quantile regression on growth rates and maximum likelihood fits to Laplace distributions using firm-level panel data. Survival-biased samples require entrant-exit corrections (Hsieh and Klenow, 2007).
What are key papers on firm growth rates?
Melitz (2002, 3056 citations) models trade-induced selection; Hsieh and Klenow (2007, 1971 citations) quantify misallocation; Brandt et al. (2011, 2176 citations) analyze Chinese productivity growth.
What open problems exist in firm growth research?
Unresolved issues include microfoundations for Laplace tails beyond selection and policy impacts on growth dispersion in services. Data limitations hinder cross-country scaling comparisons.
