This paper compares the innovation performance of established pharmaceutical firms and biotech companies, controlling for differences in the scale and scope of research. We develop a structural model to analyze more than 3,000 drug R&D projects advanced to pre-clinical and clinical trials in the...

This paper measures differences in the innovation performance of different types of firms in the pharmaceutical industry. We compare the innovation performance of incumbent firms with entrants, controlling for differences in the scale and scope of research, both at the firm level and at the...

This paper compares the innovation performance of established pharmaceutical firms and biotech companies, controlling for differences in the scale and scope of research. We develop a structural model to analyze more than 3,000 drug research and development projects advanced to preclinical and...

This paper explored an unusually comprehensive dataset of more than 2,000 drug R&D projects all over the world during the 1990s. This enabled us to characterise several features of the innovation process in pharmaceuticals, particularly the different role and comparative R&D performance of the...

This paper provides new information, not available from other sources, on the characteristics ofthe innovation process in Europe, and on the economic use and value of European patents. Ourdata are drawn from a survey (PatVal-EU, or PatVal for short) of 9,017 patents granted by theEuropean Patent...

Based on a survey of the inventors of 9,017 European patented inventions, this paper provides new information about the characteristics of European inventors, the sources of their knowledge, the importance of formal and informal collaborations, the motivations to invent, and the actual use and...
