SUPERCEDES EORKING PAPER 17-32 Buzard et al. (2017) show that American R&D labs are highly spatially concentrated even within a given metropolitan area. We argue that the geography of their clusters is better suited for studying knowledge spillovers than are states, metropolitan areas, or other...

We employ a unique data set to examine the spatial clustering of about 1,700 private research and development (R&D) labs in California and across the Northeast corridor of the United States. Using these data, which contain the R&D labs' complete addresses, we are able to more precisely locate...

The knowledge production function, which has initially been suggested as a mean to measure of technological externalities, is extended here to the spatial dimension. After accounting for spatial autocorrelation, two interesting results are worth noting : 1) distance matters when it comes to...

We study the relationship between firm centralization and organizational reproduction in satellite locations. For decentralized firms, the ethnic compositions of inventors in satellite locations mostly resemble their host cities, with little link to the inventor composition of their parent...

We analyse the determinants of national R&D expenditure and patenting activity. In contrast to most related studies, we account for factors that impact on small, distant countries. These factors include country size, firm size, distance from major economic centres, and industrial structure. We...

In this paper we address the manifold nature of knowledge through the analysis of four distinct but complementary phenomena (Internet hyperlinks, European research networks, EPO co-patent applications, Erasmus students mobility) that characterize knowledge as an intrinsic relational structure...

We investigate the role of universities as a knowledge source for regional innovation processes. The contribution of universities is tested on the level of German NUTS-3 regions (Kreise) by using a variety of indicators. We find that the intensity and quality of the research conducted by the...

It is often claimed that universities act as local knowledge factories. Although this function is largely analyzed in previous research, there still is a knowledge gap regarding the role of a technological match between the profiles of partners in university-industry interactions. In addition,...

Collaboration over distance is difficult to maintain in innovation projects which require a great deal of regional collaboration. However, patent documents reveal that a number of inventor teams are able to overcome long distances. Earlier literature started to investigate factors, which...

The question of the determinants of inter-regional knowledge flows has received a growing interest in the recent past. Particularly, the question of the relationship between geography and networks has been debated. Yet, at the inter-regional level, there is no study assessing the effect of...
