We use administrative corporate tax data from the IRS to study a particular form of tax avoidance for US multinational corporations (MNCs). This strategy relies on cost sharing agreements (CSAs), which govern joint R&D efforts conducted with foreign affiliates and allow US MNCs to shift profits...

We document the structural transformation of innovation using historical patent data since the 1850s, along with R&D expenditure and TFP growth for the post-war period. Over time, innovation has shifted from agricultural sectors to manufacturing, and, more recently, to services. We develop and...

We quantify the private returns to government R&D contracts awarded to firms. We present new evidence that R&D contracts not only finance innovation but also embed an implicit government guarantee of noncompetitive future procurement for the winning R&D contractor. We measure its private value...

Historical accounts suggest that Jewish émigrés from Nazi Germany revolutionized U.S. science. To analyze the émigrés' effects on chemical innovation in the U.S. we compare changes in patenting by U.S. inventors in research fields of émigrés with fields of other German chemists. Patenting...

This study examines the ethnic identity of authors in over 2.5 million scientific papers written by US-based authors from 1985 to 2008, a period in which the frequency of English and European names among authors fell relative to the frequency of names from China and other developing countries....

This paper surveys the major changes in patent policy and practice that have occurred in the last two decades in the U.S., and reviews the existing analyses by economists that attempt to measure the impacts these changes have had on the processes of technological change. It also reviews the...

Corporate science in America emerged in the interwar period, as some companies set up state-of-the-art corporate laboratories, hired trained scientists, and embarked upon basic research of the kind we would associate today with academic institutions. Using a newly assembled dataset on U.S....

Innovation policy can be a crucial component of governments' responses to crises. Because speed is a paramount objective, crisis innovation may also require different policy tools than innovation policy in non-crisis times, raising distinct questions and tradeoffs. In this paper, we survey the...

Research Joint Ventures (RJVs) are projects that combine the research resources of different firms. A sample of RJVs supported by the U.S. Advanced Technology Program shows that the projects yield revenues that are far less than costs. Related to this point, the RJVs are subject to...

The estimates indicate that cancer sites about which more research-supported articles were published since the 1970s had larger reductions in premature mortality and hospitalization during the period 1999-2013, controlling for the change in the number of people diagnosed. Cancer sites for which...
