Growth cycles: transformation and regional development
Departing from the renewed interest within economic history and neo-Schumpeterian perspectives on growth and economic transformation, we will suggest a theoretical framework for analyzing long term regional economic growth and transformation. Emphasis will be given to different driving forces and their various roles over time, lead-lag relations between industries and how divergence and convergence between regions shift cyclically as consequences of technological change, market integration and economic growth. We claim that systemic approaches in general have been neglected in regional science in favor of “neoregionalism” in the sense that the study of regional growth has been focusing for years on regional innovation systems and cluster theories without any regard to systemic relations at all. Using detailed time series data and applying a systemic approach we will follow Swedish regions from the structural crises in the mid 1970s to the starting point of the present financial crises. Our results suggest that there are time lags as well as systemic spatial asymmetries between industries and regions leading to changing patterns of divergence and convergence in the regional system. Furthermore, there are indications that the regional disparities between centre and periphery have increased compared to the situation in the mid 1970s.
Who Needs Agglomeration? Varying Agglomeration Externalities and the Industry Life Cycle
In this paper, the changing roles of agglomeration externalities during different stages of the industry life cycle are investigated. A central argument is that agglomeration externalities vary with mode of competition, innovation intensity, and characteristics of learning opportunities in industries. Following the Industry Life Cycle perspective, we distinguish between young and mature industries, and investigate how these benefit from MAR, Jacobs’ and Urbanization externalities. The empirical analysis builds on a Swedish plant level dataset that covers the period of 1974-2004.The outcomes of panel data regression models show that the benefits industries derive from their local environment are strongly associated with their stage in the industry life cycle. Whereas MAR externalities increase with the maturity of industries, Jacobs’ externalities decline when industries are more mature. This is in line with the hypothesis that young industries operate in an environment dominated by rapid product innovation and low levels of standardization. Hence, it pays off when knowledge can be sourced locally from many different sources, but there is still little scope for specialization benefits. Mature industries, in contrast, are associated with lower innovation intensities and a focus on cost saving process innovations. Therefore, there are major benefits to be derived from specialization, whereas knowledge spillovers from different industries are less relevant. The distinction between the product competition in young industries and price competition in mature industries is reflected in our finding that high regional factor costs are detrimental to mature industries, but not to young industries. This can also be related to the finding that high quality living environments, attractive for highly paid employees, are important to young industries. Overall, the outcomes stress that industrial life cycles have to be taken into account in the analysis of agglomeration externalities.agglomeration externalities, industry life cycle, urbanization, Sweden
The Dynamics of Agglomeration Externalities along the Life Cycle of Industries
This paper investigates the changing roles of agglomeration externalities along the industry life cycle. We argue that industries have different agglomeration needs in different stages of their life cycles because their mode of competition, innovation intensity, and characteristics of learning opportunities change over time. For 12 Swedish manufacturing industries, we determined for each year between 1974 and 2004 whether the industry was in a young, intermediate, or mature stage. Whereas MAR externalities steadily increased with the maturity of industries, the effect of local diversity (Jacobs’ externalities) was positive for young industries but declined and even became negative for more mature industries

Educational attainment does not influence brain aging.
Education has been related to various advantageous lifetime outcomes. Here, using longitudinal structural MRI data (4,422 observations), we tested the influential hypothesis that higher education translates into slower rates of brain aging. Cross-sectionally, education was modestly associated with regional cortical volume. However, despite marked mean atrophy in the cortex and hippocampus, education did not influence rates of change. The results were replicated across two independent samples. Our findings challenge the view that higher education slows brain aging
The European union’s 2010 target: Putting rare species in focus
P. 167-185The European Union has adopted the ambitious target of halting the loss of biodiversity by
2010. Several indicators have been proposed to assess progress towards the 2010 target, two
of them addressing directly the issue of species decline. In Europe, the Fauna Europaea
database gives an insight into the patterns of distribution of a total dataset of 130,000 terrestrial
and freshwater species without taxonomic bias, and provide a unique opportunity
to assess the feasibility of the 2010 target. It shows that the vast majority of European species
are rare, in the sense that they have a restricted range. Considering this, the paper discusses
whether the 2010 target indicators really cover the species most at risk of extinction.
The analysis of a list of 62 globally extinct European taxa shows that most contemporary
extinctions have affected narrow-range taxa or taxa with strict ecological requirements.
Indeed, most European species listed as threatened in the IUCN Red List are narrow-range
species. Conversely, there are as many wide-range species as narrow-range endemics in
the list of protected species in Europe (Bird and Habitat Directives). The subset of
biodiversity captured by the 2010 target indicators should be representative of the whole
biodiversity in terms of patterns of distribution and abundance. Indicators should not overlook
a core characteristic of biodiversity, i.e. the large number of narrow-range species and
their intrinsic vulnerability. With ill-selected indicator species, the extinction of narrowrange
endemics would go unnoticedS
