July 2020Skilled Human Capital and High-Growth Entrepreneurship: Evidence from Inventor Inflows
with Benjamin Balsmeier, Matt Marx, Seungryul Ryan Shin: w27605
To what extent does high-growth entrepreneurship depend on skilled human capital? We estimate the impact of the inflow of inventors into a region on the founding of high-growth firms, instrumenting mobility with the county-level share of millions of inventor surnames in the 1940 U.S. Census. Inventor immigration increases county-level high-growth entrepreneurship; estimates range from 29-55 immigrating inventors for each new high-growth firm, depending on the region and model. We also find a smaller but significant negative effect of inventor arrival on entrepreneurship in nearby counties.

We document three facts related to innovation and entrepreneurship in renewable energy. Using data from the US Patent and Trademark Office, we first show that patenting in renewable energy remains highly concentrated in a few large energy firms. In 2009, the top 20% firms accounted for over 40% of renewable energy patents in our data. Second, we compare patenting by venture capital-backed startups and incumbent firms. Using a variety of measures, we find that VC-backed startups are engaged in more novel and more highly cited innovations, compared to incumbent firms. Incumbent firms also have a higher share of patents that are completely un-cited or self-cited, suggesting that incumbents are more likely to engage in incremental innovation compared to VC-backed startups. Third, we document a...
