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...

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 estimates the determinants of labour productivity and employment in European NUTS2 regions. We focus on technological capabilities (proxied by regional patents), agglomeration economies (employment density), and openness, proxied by the number of airplane passengers embarked and...

This paper studies the determinants of the quantity and quality of inventors’ patents. It uses a sample of 793 inventors drawn from the PatVal-EU dataset and the information on EPO patents that they contributed to inventing during the period 1988-1998. It explores three aspects of the...

This paper examines empirically the relationship between the internal technological profile and the diversification through strategic alliances of the largest 219 industrial firms world-wide. It explores three related issues. First, the paper shows that firms? internal technological...

According to the Sectoral Systems of Innovation and Production approach, the analysis of a specific sector has to describe its knowledge and technological base, existing complementarities among knowledge, technologies and products, the heterogeneity of agents, their learning processes and...

This paper estimates the determinants of labour productivity in European NUTS regions during 1989-1996. We compare three potential explanations of regional advantages: Technological capabilities (proxied by regional patents), agglomeration economies (employment density), and openness. To study...
