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...

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...

This paper attempts to explain knowledge production in Swedish functional regions as measured by the number of patent applications. Recognizing that technological opportunity differs across sectors, a sectoral analysis is conducted. The Knowledge Production Function (KPF) approach is applied in...

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 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....

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...

Schumpeter claimed the entrepreneur to be instrumental for creative destruction and industrial dynamics. Entrepreneurial entry serves to transform and revitalize industries, thereby enhancing their competiveness. This paper investigates if entry of new firms influences productivity amongst...

This paper reassesses the relationship between density and productivity by using detailed geo-coded data on wages and employment in Sweden. The contribution is empirical and builds on an analysis of spatial units of exactly the same size in terms of geographic surface. The data divide Sweden...

This paper develops a framework to appreciate the observed heterogeneity of firm size distributions and the entry and exit of products and firms associated with it. It is based on a model where new products are introduced by innovating firms in a quasi-temporal setting of monopolistic...
