Tidskriftsartikel (refereegranskat)abstract
- This paper studies the innovative performance of 130 Swedish corporations during 1993-1994. 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, within and between corporations located across regions, is introduced. We examine the relative importance of intra- and interregional knowledge sources from 1) the own corporation, 2) other corporations, and 3) universities. The results show that there is a positive relationship between the innovativeness of a corporation and its accessibility to university researchers within regions where own research groups are located. Good accessibility among the corporation's research units does not have any significant effects on the likelihood of generation of patents. Instead the size of the R&D staff of the corporation seems to be the most important internal factor. There is no indication that intraregional accessibility to other corporations' research is important for a corporation's innovativeness. However, there is some indication of reduced likelihood for own corporate patenting when other corporate R&D is located in nearby regions. This may reflect a negative effect from competition for R&D labor.

- This paper examines howtechnologyspecialization, measured by citation-weighed patents, affects trade flows. The paper analyzes the relationship between (i)technologyspecializationandexportspecializationacross regions and (ii) thetechnologyspecializationof origin and destination and thequalityofexportflows. We find that theexportspecializationof regions corresponds to theirtechnologyspecialization. Regions with highertechnologyspecializationexportproducts of higherquality, as indicated by higher prices. Moreover,exportflows to destination countries with a hightechnologyspecializationconsist of products of higherqualityin the specifictechnology. The results are consistent with knowledge andtechnologybeing important forexportperformance and with regions with higherspecializationin atechnologybeing better equipped to produce high-qualityproducts. They are also consistent with destinations of highertechnologyspecialization, having a more pronounced demand for products of higherqualityin the sametechnology.

Process Innovations in a Duopoly with Two regions
- 2004
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Most models of duopolies with a spatial dimension refer to the ’linear’ or ’circular’ city. Moreover, in duopoly models with innovations, the spatial dimension is usually dropped. We bridge this gap by constructing a model with two regions, each hosting production of a differentiated quality (high and low quality). In addition, consumers are heterogenous with different willingness to pay for quality. The analysis focuses on the incentives for process innovations, which affect the unit cost of production. The model captures two common trends in the urbanization process, and their effects on the incentive for process innovations. The first is regional enlargement or reduced transport costs. We find that such changes raise the proportion of process R&D in the region producing the low-quality good relative to process R&D from the high-quality region. Second, we examine the effect on optimal process R&D of moving consumers from the low-quality to the high-quality region. This lowers the optimal amount of process R&D undertaken in the low-quality region, while it is raised in the high-quality region.
