<em>Poles of competitiveness, the ambiguous comeback of local applications of the French industrial policy</em> - The French experiment of the "Pôles de compétitivité" is an original initiative of the French authorities in order to promote innovation-oriented collaborations and synergies between large...

This paper investigates the existence and characteristics of localized knowledge extemalities within the Paris region, lle-de-France, across biotechnology firms using business level data between 2000 and 2005. We test the combined effect of geographic and technological proximity on the firms'...

In this paper, we propose an exploratory approach which is essentially methodological and empirical in order to explore geographic proximity at the intra-regional level. Recent works suggest that a firm has to be located in a close neighborhood in order to benefit from knowledge externalities,...

This paper investigates the determinants of co-inventor tie formation using micro-data on genomic patents from 1990 to 2006 in France. We consider in a single analysis the relational and proximity perspectives that are usually treated separately. In order to do so, we analyse the determinants of...
