Contrary to an accepted wisdom, this paper shows that cross-country variations in the number of patents per researcher do not only reflect differences in the propensity to patent but also signals differences in research productivity. We put forward and tes ...
This thesis proposes three studies that provide novel empirical evidence on how different types of proximity can affect innovation and science activities through various mechanisms and in different contexts. In the first study (second chapter of this thesi ...
The U.S. government invests more than $50 billion per year in R&D procurement but we know little about the outcomes of these investments. We have traced all the patents arising from government funding since the year 2000. About 1.5 percent of all R&D procu ...
This paper assesses the extent to which the international migration of inventors affects innovation in the receiving country. Drawing on a novel database that maps the migratory patterns of inventors, we exploit the end of the Soviet Union and the conseque ...
Patents have traditionally been used in the history of technology as an indication of the thinking process of the inventors, of the challenges or “reverse salients” they faced, or of the social groups influencing the construction of technology. More recent ...
This article decomposes the R&D-patent relationship at the industry level to shed light on the sources of the worldwide surge in patent applications. The empirical analysis is based on a unique data set that includes five patent indicators computed for 18 ...
This paper describes a new patent-based indicator of inventive activity. The indicator is based on counting all the priority patent applications filed by a country's inventors, regardless of the patent office in which the application is filed, and can ther ...
Patent-based indicators at the country level are frequently used to assess countries' innovation performances or efforts. Yet they are often said to reflect the propensity to patent rather than actual research productivity. The authors of this article argu ...
The invention relates to a method and a device for sequencing nucleic acid mols. on a perforated membrane. The inventive method and device can be esp. used in multiplex sequencing. The method involves prepg. an oligonucleotide that is labeled to satn. with ...
