Well functioning Markets for Technology (MFT) allow inventors to sell their inventions to others that may derive more value from them. We argue that the growing reliance on science in inventions enhances MFT. In addition to higher quality inventions, reliance on science may enhance gains from...

Scientific knowledge is believed to be the wellspring of innovation. Historically, firms have also invested in research to fuel innovation and growth. In this paper, we document a shift away from scientific research by large corporations between 1980 and 2007. We find that publications by...

A defiining feature of modern economic growth is the systematic application of science to advance technology. However, despite sustained progress in scientific knowledge, recent productivity growth in the U.S. has been disappointing. We review major changes in the American innovation ecosystem...

We estimate the effect of patent protection on follow-on investments in corporate scientific research. We exploit a new method for identifying an exogenous reduction in the protection a granted patent provides. Using data on public, research-active firms between 1990 and 2015, we find that firms...

If scientific knowledge is a public good, why do firms invest in research? This paper revisits this classic question with new data on patent citations to scientific publications by corporations. Using data on 4,736 firms for the period 1980-2006, we document that corporate investment in research...

This paper studies knowledge sharing in alliances and alliance portfolios. We develop a theoretical framework that encompass as special cases the problems of knowledge misappropriation and asymmetric learning and show that, once the issue of encouraging effective collaboration is put...

We study the relationship between decentralization of R&D, innovation and firm performance using a novel dataset on the organizational structure of 1,290 American publicly-listed corporations, 2,615 of their affiliate firms, as well as characteristics of 594,903 patents that they hold. We...
