We study the structure of the spatial inventor networks in Sweden by examining the residence of inventors and coinventors in Swedish patent applications to the European Patent Office. Several factors are found to influence the spatial affinity. We find that spatial affinity is strongly...

Although Sweden is one of the most R&D-intensive OECD-countries, the importance of R&D spillovers in the country has not been systematically analyzed. This paper employs a cross-sectional dataset of 264 R&D-performing Swedish firms from 1996-97. With this set, knowledge production functions are...

Recent studies have documented extensive heterogeneity in firm performance within countries, and innovation has been found as an important determinant. This paper addresses the issue of innovation firm performance across countries. A growing number of national firm level studies on the...

Recent empirical evidence strongly supports Jacobs’ (1969) externality hypothesis, that urban diversity provides a more favorable environment for economic development. In order to correctly gauge Jacobs’ hypothesis, economic development should be understood as a result of innovations....

In general there is agreement about the positive impacts of R&D on performance of firms measured as productivity, profitability and growth. However, the opposite relationship is less obvious and very little attention has been paid on examining the feedback from performance on investment. This...

The link between proximity and innovation has been dwelled upon extensively in the literature. A regional economic milieu characterized by proximity between relevant actors is maintained to be suitable for establishing and maintaining successful regional innovation system. In this paper it is...

The paper studies innovative performance of 130 Swedish corporations for 1993-94, using number of patents per corporation as a function of internal and external knowledge sources to the corporation. A coherent way of handling accessibility measures, within and between corporations located across...

An empirical method to identify the existence of a spatial cluster is proposed. The method, based upon regression analysis, offers researchers to categorise regions, municipalities, or cities with respect to their over- or under-representation in number of establishments and employment for any...

In recent decades the world has witnessed the emergence of a global knowledge economy. For example, the evolution in recent decades of the developed economies has been accompanied by a regional shift in economic activity away from traditional industrial regions to new agglomerations of high...

The main purpose in this paper is to study to what extent accessibility to R&D can explain patent production. Therefore a knowledge production function is estimated both on aggregated level and for different industrial sectors. The output of the knowledge production is the number patent...
