The paper studies venture capital's role in the geographic clustering of high-growth startups. We exploit a rule change that disproportionately impacted U.S. regions that historically lacked VC financing via a restriction of banks to invest in the asset class. A one-standard-deviation increase in VCs' exposure to the rule led to an 18% decline in fund size and a 10% decrease in the likelihood of raising a follow-on fund. Startups were not wholly cushioned: financing and valuations declined. Startups also moved out of impacted states after the rule change, likely exacerbating existing geographic disparity in entrepreneurship.

We examine the value of skilled immigrants in finance by exploiting two natural experiments. We find that hedge fund management companies that secure more H-1B visas in random lotteries deliver higher alphas, Sharpe ratios, and information ratios. Moreover, an unexpected reduction in the H-1B quota undermined the performance of hedge funds that were dependent on H-1B workers. The superior performance of funds with high H-1B visa allocations can be attributed to highly-educated, well-paid, and motivated H-1B workers with quantitative skills. H-1B workers add value by helping hedge funds overcome capacity constraints, arbitrage prominent stock anomalies, and develop distinctive investment strategies.

We examine whether VC-backed startups respond to R&D tax incentives by attempting to scale R&D activities through employment. We exploit a provision of the PATH Act of 2015, which allows qualified small businesses to offset payroll taxes with R&D tax credits, and show that marginally eligible startups increase their demand for R&D workers more than marginally ineligible startups after the PATH Act’s enactment in 2015. Marginally eligible startups not only ramp up recruiting of workers of higher quality, but also subsequently file more patents with new inventors. Our findings reveal that tax incentives can stimulate startup R&D activities through skilled labor recruitment.

We study how intellectual property (IP) protection impacts local firms' innovation incentives and patenting strategies. Exploiting the staggered establishment of specialized IP courts across Chinese regions, we show that strengthening IP protection leads to higher R&D investments but lower patenting activities. Higher litigation risk from disclosing inventions seems to dominate the benefit of stronger protections gained from patenting. Consistent with this explanation, we find that firms reduce patenting mainly in technology fields where their industry rivals have previously patented. Overall, our findings suggest that enhancing IP protection encourages more innovation efforts, possibly in uncharted technology areas.
This paper focuses on angel financing, and its interaction with the venture capital (VC) market. I collect the first systematic dataset on angel financing. Using this data, I find that the angel capital market is large, and angel financing has causal impacts on VCs: initial angel investments lead VCs to re-allocate financing from early to later rounds.
