The TRIPS Agreement, which specifies minimum levels of intellectual property protection for countries in the WTO, has increased levels of patent protection around the world. Using variation across countries in the timing of patent laws and the severity of disease, we test the hypothesis that...

We examine the role of spillover learning in shaping the value of exploratory versus incremental R&D. Using data from drug development, we show that novel drug candidates generate more knowledge spillovers than incremental ones. Despite being less likely to reach regulatory approval, they are...

Operation Warp Speed (OWS) was a U.S. government-led program to accelerate the development, production, and administration of COVID-19 vaccines. The program cut the typical ten-year timeline needed to develop a new vaccine down to ten months and began vaccinating vulnerable populations within a...

While most economists believe that public scientific research fuels industry innovation and economic growth, systematic evidence supporting this relationship is surprisingly limited. In a recent study, Acemoglu and Linn (2004) identified market size as a significant driver of drug innovation in...

Multinational enterprises' research and development (R&D) activities are increasingly internationalised and organised into new types of network, as part of their global innovation networks. In this article, we investigate the dynamics and strategies of R&D reorganisation through an in-depth case...

Research on intellectual property has focused on formal legally recorded rights that we call deeded, most often measured by granted patents. Meanwhile, other "defacto" IP (mainly purposive secrecy and natural excludability) has become more important because of the increasing closeness of...

Even though management consultants increasingly recommend that in-house research be outsourced, little is known about the conditions favoring substitution or complementarity between internal R&D and external technology acquisition. In this paper, we attempt to provide a deeper understanding of...

Existing research has focused on why and when firms may choose to access the external technology market. Surprisingly, however, less is known about the reliability of the patents attached to these external technologies in the face of litigation. “Weak” external patents expose a firm to the...
