Synergizing Ventures
Venture capital (VC) and growth are examined both empirically and theoretically. Empirically, VC-backed startups have higher early growth rates and initial patent quality than non-VC-backed ones. VC backing increases a startup's likelihood of reaching the right tails of the firm size and innovation distributions. Furthermore, outcomes are better for startups matched with more experienced venture capitalists. An endogenous growth model, where venture capitalists provide both expertise and financing for business startups, is constructed to match these facts. The presence of venture capital, the ...

The Impact of the 2017 Tax Cuts and Jobs Act on U.S. Multinationals’ Intangible Assets
This paper investigates the impact of the 2017 Tax Cuts and Jobs Act (TCJA) on U.S. multinationals’ intangibles. We develop a theoretical model that incorporates key provisions of the TCJA—the Global Intangible Low-Taxed Income (GILTI) and the Foreign-Derived Intangible Income (FDII)—and derive testable implications for changes in licensing and patent transfer patterns. Using data on international royalty flows and patent assignments, we test the model’s predictions. Our findings suggest that the TCJA may have impacted profit shifting strategies through intangibles, aligning with our ...
Transfer Pricing of Intangible Assets: Evidence from Patent Data
To reduce their tax exposure, multinationals may seek to shift profits to countries with lower tax rates. Do patents play a role in this strategy?

Lockdowns and Innovation: Evidence from the 1918 Flu Pandemic
Does social distancing harm innovation? We estimate the effect of non-pharmaceutical interventions (NPIs)—policies that restrict interactions in an attempt to slow the spread of disease—on local invention. We construct a panel of issued patents and NPIs adopted by 50 large US cities during the 1918 flu pandemic. Difference-in-differences estimates show that cities adopting longer NPIs did not experience a decline in patenting during the pandemic relative to short-NPI cities, and recorded higher patenting afterward. Rather than reduce local invention by restricting localized knowledge ...
Profit Shifting in the 21st Century: Multinationals’ Use of Intrafirm Patent Transfers
An analysis indicates that a high percentage of U.S. patents that shifted to tax havens like Bermuda are intrafirm transfers. Such transfers may be a tax avoidance strategy by multinationals.
East Asia Outpaces Other Regions in International Patenting
As foreign patenting continues to grow, East Asia has become both the main origin of innovations and the main destination for patent protection.

Patents to Products: Product Innovation and Firm Dynamics
We study the relationship between patents and actual product innovation in the market, and how this relationship varies with firms’ market share. We use textual analysis to create a new data set that links patents to products of firms in the consumer goods sector. We find that patent filings are positively associated with subsequent product innovation by firms, but at least half of product innovation and growth comes from firms that never patent. We also find that market leaders use patents differently from followers. Market leaders have lower product innovation rates, though they rely on ...

Bubbles and the Value of Innovation
Episodes of booming innovation coincide with intense speculation in financial markets leading to bubbles—increases in market valuations and firm creation followed by a crash. We provide a framework reproducing these facts that makes a rich set of predictions on how speculation changes both the private and social values of innovation. We confirm the theory in the universe of U.S. patents issued from 1926 through 2010. Measures based on financial market information indicate that speculation increases the private value of innovation and reduces negative spillovers to competing firms. No ...
