By drawing information from a survey of inventors of 9,017 European patents (PatVal-EU), this paper provides novel and detailed data about the characteristics of the European inventors, the sources of their knowledge, the importance of formal and informal collaborations among researchers and...

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...

This paper studies the geographical breadth of knowledge spillovers. Previous research suggests that knowledge spillovers benefit from geographical proximity in technologically active and rich regions more than elsewhere. An alternative view explains the geographical breadth of knowledge...

This paper uses a novel database composed of 4,262 European chemical patents applied for by 693 firms during 1987-1996 to compare the relative effect of firm and regional characteristics on the production of technological hits (highly cited patents). By using an extensive set of controls, the...

This paper estimates the determinants of labour productivity in European NUTS regions during 1989-1996. Unlike previous studies, which have focussed either on local technological capabilities or on agglomeration economies, we compare three potential explanations of regional advantages:...

This paper examines the relationship between the location of R&D and production activities. By using a sample of 799 Japanese investments in Europe, it distinguishes between affiliates performing only R&D, both R&D and production, and production only. The analysis produces two main results....

This paper discusses the role of education in shaping the geographical breadth of knowledge spillovers. Data pertaining to 6,051 European inventions reveal that inventors with a high level of education, such as a university or doctoral degree, rely more on external spillovers regardless of the...
