High-Growth Firms in the United States: Key Trends and New Data Opportunities
Using administrative data from the U.S. Census Bureau, we introduce a new public-use database that tracks activities across firm growth distributions over time. With these new data, we uncover several key trends for high-growth firms---critical engines of innovation and economic growth. First, the share of firms that are high-growth has steadily decreased over the past four decades, driven not only by falling rates of entrepreneurship but also languishing growth among existing firms. Second, this decline is particularly pronounced among young and small firms, while the share of high-growth ...

Puzzlingly Divergent Trends in Household Wealth and Business Formation
The rate of new business formation has declined sharply in recent decades, raising concerns among economists about job and productivity growth. This observed decline in business formation is likely to be juxtaposed to changes in characteristics such as household wealth that affect households’ propensity to become entrepreneurs. Economic theories of business formation suggest that wealthier households are more likely to start a business because wealth allows them to more easily reach a profitable scale.Justin Barnette and Andrew Glover use data from the Panel Study of Income Dynamics from ...

Business Dynamics in the National Establishment Time Series (NETS)/Leland Crane, Ryan Decker
Business microdata have proven useful in a number of fields, but the main sources of comprehensive microdata are subject to significant confidentiality restrictions. A growing number of papers instead use a private data source seeking to cover the universe of U.S. business establishments, the National Establishment Time Series (NETS). Previous research documents the representativeness of NETS in terms of the distribution of employment and establishment counts across industry, geography, and establishment size. But there exists considerable need among researchers for microdata suitable for ...

Reparations and Persistent Racial Wealth Gaps
Reparations is a policy proposal aiming to address the wealth gap between Black and White households. We provide a first formal analysis of the economics of reparations using a long-run model of heterogeneous dynasties with an occupational choice and bequests. Our innovation is to introduce endogenous dispersion of beliefs about risky returns, reflecting differences in dynasties' experiences with entrepreneurship over time. Feeding the exclusion of Black dynasties from labor and capital markets as driving force, the model quantitatively reproduces current and historical racial gaps in wealth, ...

Competition, syndication, and entry in the venture capital market
There are two ways for a venture capital (VC) firm to enter a new market: initiate a new deal or form a syndicate with an incumbent. Both types of entry are extensively observed in the data. In this paper, I examine (i) the causes of syndication between entrant and incumbent VC firms, (ii) the impact of entry on VC contract terms and survival rates of VC-backed start-up companies, and (iii) the effect of syndication between entrant and incumbent VC firms on the competition in the VC market and the outcomes of incumbent-backed ventures. By developing a theoretical model featuring endogenous ...

Boom Town Business Dynamics
The shale oil and gas boom in the U.S. provides a unique opportunity to study economic growth in a "boom town" environment, to derive insights about economic expansions more generally, and to obtain clean identification of the causal effects of economic growth on specific margins of business adjustment. The creation of new business establishments--separate from the expansion of existing establishments--accounts for a disproportionate share of the multi-industry employment growth sparked by the shale boom, an intuitive but not inevitable empirical result that is broadly consistent with ...

Changing Business Dynamism and Productivity : Shocks vs. Responsiveness
The pace of job reallocation has declined in all U.S. sectors since 2000. In standard models, aggregate job reallocation depends on (a) the dispersion of idiosyncratic productivity shocks faced by businesses and (b) the marginal responsiveness of businesses to those shocks. Using several novel empirical facts from business microdata, we infer that the pervasive post-2000 decline in reallocation reflects weaker responsiveness in a manner consistent with rising adjustment frictions and not lower dispersion of shocks. The within-industry dispersion of TFP and output per worker has risen, while ...

Agglomeration and innovation
Draft chapter for the forthcoming Handbook of Regional and Urban Economics, Vols. 5A and 5B This paper reviews academic research on the connections between agglomeration and innovation. The authors first describe the conceptual distinctions between invention and innovation. They then discuss how these factors are frequently measured in the data and note some resulting empirical regularities. Innovative activity tends to be more concentrated than industrial activity, and the authors discuss important findings from the literature about why this is so. The authors highlight the traits of ...

Consumer Demand and Credit Supply as Barriers to Growth for Black-Owned Startups
We formulate a framework showing that differences in capital returns and capital intensity between groups of firms can identify relative differences in consumer demand and credit constraints. Using micro-data on Black- and White-owned startups, we find robust evidence that Black-owned startups have lower capital returns, implying that Black-owned startups face lower consumer demand due to race. In contrast, we find mixed evidence of tighter credit constraints due to race. We further show that differences in capital returns are persistent over time, whereas capital intensity differences are ...
