The exchange of technologies and technological knowledge - through joint-ventures, partnerships, licensing, cross-licensing, R&D contracts - and the upsurge of markets for technology are main features of the "knowledge-based" economy. Competitive strengths are shifting from technological aspects...

The chemical industry has often been accused of being highly responsible for environmental pollution, and chemical firms, before others, have been highly committed to solve environmental problems. In this respect, this paper assesses the contribution of the European chemical industry in...

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...

The paper develops the argument that the long-term structural evolution of an industry depends on the evolution of a vertically-related, downstream industry. We analyse two pairs of vertically-related industries, the jet and turboprop aircraft and engine industries, since the first introduction...

This paper investigates the role of skills and the division of labor among participants in collective inventions. Our analysis draws on a large sample of projects registered at Sourceforge.net, the world’s largest incubator of open source software activity. We explore the hypothesis that the...

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...

The paper explores the idea that properties at the level of firms coevolve with more aggregate properties at the level of market institutions in the dynamics of industries. We propose that the structure of network of vertical relations limits the effect of increasing returns at the firm level....

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...

A careful case study of the entire history of the turboprop engine industry (1948-1997) is offered as an example of non shakeout pattern. The persistence of high concentration is not associated to the exit of smaller manufacturers, but instead a stable coexistence of generalist and specialist...
