This paper estimates the international diffusion and obsolescence of technological knowledge by technological field and country using patent citations from the U.S. Patent and Trademark Office (USPTO) and from the European Patent Office (EPO). We control for self-citations and for procedural and...

In this paper we present a model of the long term dynamics of market structure and innovation in the pharmaceutical industry in a history friendly way. Our results show a strong increase in concentration in each therapeutic area, but a rather low level of concentration in the overall market....

This paper estimates the process of diffusion and decay of knowledge from university, public laboratories and corporate patents in six countries and tests the differences across countries and across technological fields using data from the European Patent Office. It finds that university and...

This paper estimates the diffusion and obsolescence of technological knowledge by technological field, country and type of institutions that generates it. We use two comparable samples of patents and patent citations from the NBER U.S. Patent Citations Dataset (based on patents from the US...

The Innovation Act was introduced by the French government in 1999, with the aim of encouraging academic institutions to protect and commercialize their scientists’ inventions. We explore the effects of the Act on the distribution of Intellectual Property Rights (IPRs) over academic...

This paper examines entry and survival in the US software market of a sample of firms based in India, Ireland and Israel. Our investigation focuses on pre-entry technological capabilities, international linkages and home based experience as determinants of the firm entry decision and post-entry...

The lack of firm-level data on innovative activities has always constrained the development of empirical studies on innovation. More recently, the availability of large datasets on indicators, such as R&D expenditures and patents, has relaxed these constrains and spurred the growth of a new wave...

Authorship and inventorship are attribution rights that contribute to the reputation of individual scientists, but have to be distributed across several individuals, due to the importance of teamwork in both science and technology. For academic teams that both publish and patent their research...

This paper contributes to the debate upon the trade-off between science and technology by looking at how the scientific performances of a researcher relate ex-ante to his/her attitude to patent, during his/her academic career. We run an event history analysis explaining the hazard for a...
