This paper examines how technology specialization, measured by citations-weighted patents, affects trade flows. The paper analyzes (i) the relationship between technology specialization and export specialization across regions and (ii) how the technology specialization of origin and destination...

This paper studies the innovative performance of 130 Swedish corporations during 1993-94. The number of patents per corporation is explained as a function of the accessibility to internal and external knowledge sources of each corporation. A coherent way of handling accessibility measures,...

We use a new, comprehensive database covering Swedish industry and service firms 1985-2002, to examine trends in the ratio between patenting and R&D (PR-ratio). There is a fall in PR-ratios in the long run (1985-2002) on the aggregate level and for all sectors. In general low-tech sectors...

Patent data play an important role as indicators of inventive and innovative activity across regions. This paper examines if the geographical distribution changes and in what direction if patent data are quality-adjusted. A quality index is constructed by means of factor analysis on the...

We analyze the effect of the Öresund Bridge, a combined railway and motorway bridge between Swedish Malmö and the Danish capital Copenhagen, on inventive activity in the region of Malmö. Applying difference-in-difference estimation on individual-level data, our findings suggest that the...

Knowledge production function approaches to estimation of knowledge flows in regions have recently come under attack not to open the ’black box’ of knowledge creation and it has been questioned whether spillovers really are the key determinant of knowledge diffusion rather than market...

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...

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...
