Liberty in Law? Intellectual Property Rights and Global Alliance Networks

Working Papers

We explore how intellectual property rights (IPR), a type of formal institution, affect firms’ access to global alliance networks and their positioning within those networks. We employed a difference-in-difference design to assess the impact of IPR reforms across thirteen countries.Read More

IP Litigation Is Local, But Those Who Litigate Are Global

Working Papers

While there has been a growing literature on the globalization of R&D and intellectual property (IP) strategies, most of the extant studies are conducted at a specific location or a specific point in time. The three projects in this program aim to provide a holistic view of firms’ global R&D footprint.Read More

Using Machine Learning to Predict High-Impact General Technologies

Working Papers

Can machine learning techniques be used to predict high-impact, general technologies? We find that an ensemble of deep learning models that analyze both the text of patents as well as their bibliometric information can ex-ante identify such patents, accurately identifying 80 of the top 100 high generality patents in the hold-out sample.

Patent Litigation Risk and VC Investments

Funded Research Proposal

As VC firms have an acute interest in high-tech companies, they potentially bear substantial risk of patent litigation. In this project, we aim at looking into the following questions: how do ex-ante and ex-post patent litigation risks affect VC firms’ investment strategies and how those risks is propagated among all portfolio companies they have invested?Read More

Managing Valuable Knowledge in Weak IP Protection Countries

Published Research

Although knowledge assets provide multinational corporations with competitive advantages in foreign markets, it can be difficult for firms to protect their knowledge in foreign countries – especially countries with weak intellectual property (IP) protection.Read More

Innovation and Intellectual Property Strategies of Multinational Enterprises

Funded Research Proposal

While there has been a growing literature on the globalization of R&D and intellectual property (IP) strategies, most of the extant studies are conducted at a specific location or a specific point in time. The three projects in this program aim to provide a holistic view of firms’ global R&D footprint, and to integrate IP strategies into firms’ overall globalization efforts. Read More

The NPE: Benevolent Middleman or Stick-Up Artist?

Working Papers

How do non-practicing entities impact innovation? This question has enormous relevance to industrial policy, with virtually no direct evidence to inform it. There are two dominant theoretical perspectives, one of which views Non-Practicing Entities (NPEs) as benevolent middlemen reallocating intellectual property (IP) to where it can be best used.Read More

Patent Value and Citations: Creative Destruction or Strategic Disruption?

Working Papers

Prior work suggests that more valuable patents are cited more and this view has become standard in the empirical innovation literature. Using an NPE-derived dataset with patent-specific revenues we find that the relationship of citations to value in fact forms an inverted-U, with fewer citations at the high end of value than in the middle.Read More

Beyond Citations: Determinants of Patent Value

Working Papers

The use of patents in economic research is complicated by the fact that patents vary enormously in their importance or value. While fewer than 10 percent of patents are worth the money spent to secure them, the most valuable ones are worth hundreds of millions of dollars.Read More

Movie piracy and sales displacement in two samples of Chinese consumers

Published Research

Intellectual property piracy is widely believed, by authorities in both US industry and government, to be rampant in China. Because we lack evidence on the rate at which unpaid consumption displaces paid consumption, we know little about the size of the effect of pirate consumption on the volume of paid consumption.

“Lost” on the Web: Does Web Distribution Stimulate or Depress Television Viewing?

Published Research

In the past few years, YouTube and other sites for sharing video files over the Internet have vaulted from obscurity to places of centrality in the media landscape. The files available at YouTube include a mix of user-generated video and clips from network television shows.Read More
