No. 13,
2008
Abstract
The ‘cluster theory’ has become one of the main concepts promoting regional competitiveness, innovation, and growth. As most studies focus on measures of concentration of one industrial branch in order to identify regional clusters, the appropriate analysis of specific vertical relations within a value-adding chain is developing in this discussion. This paper tries to identify interrelated sectors via national input-output tables with the help of Minimal Flow Analysis by Schnabl (1994). The regionalization of these national industry templates is carried out with the allocation of branch-specific production values on regional employment. As a result, the paper shows concentrations of vertical clusters in only 27 of 439 German NUTS-3 regions.

Spatially Concentrated Industries as Innovation Driver? – Empirical Evidence from East Germany
Christoph Hornych, Michael Schwartz
Wirtschaft im Wandel,
No. 9,
2008
Abstract
A positive relation between the spatial concentration of sectors and their capacity of innovation is frequently assumed in regional science as well as in regional development policy. Therefore, with the support of sectoral agglomeration, effects on the regional technological performance are expected. However, previous empirical work is inconsistent in supporting this interdependency.
This study aims to examine the effects of sectoral agglomeration on innovative activities in East-German regions. For this purpose, spatially concentrated industries are identified and included in the estimation of regional ‘knowledge-production-functions’. Contrary to expectations, the spatial concentration seems to inhibit the amount of patent-activities of the sector in the specific region. In contrast, positive effects are generated from research facilities. Moreover, we find evidence for intersectoral spillovers.
The results show that for innovative activities, urbanization effects have a higher relevance as localization effects. So far, spatially concentrated industries are not an innovation driver in East Germany.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Determinants of Innovative Behaviour,
2008
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

Suburban Municipalities on Trial – Analysing the Sustainability of Socioeconomic Structures at the Example of the Municipality Schkopau
Sabine Döhler, Alexander Kubis
Wirtschaft im Wandel,
No. 7,
2008
Abstract
This article analyses socio-economic criteria of municipalities next to large cities. In a case study, we examine the municipality Schkopau in the south of Saxony-Anhalt. We ask if the fusion of smaller communes to this “new” municipality created in 2004 was rational in terms of sustainable socio-economic structures. Hence, we use the criteria of satellite towns developed by Boustedt.
We show that the criterion of political independence is assured by law. Meanwhile, the criteria independence of culture and urban development are not completely fulfilled. Due to the high density of industrial enterprises, the municipality has high tax revenue and therefore a strong financial basis. Also, the criterion of the minimum population figure is implemented.
Based on the specific results of the satellite town criteria, we could not find definite results for the municipality Schkopau, they are rather ambivalent. This result is partly caused by the strong interactions within the functional area of the provinces Saxony, Saxony-Anhalt and Thuringia. Due to the high dynamic of the structural change, we also point out the necessity to enhance the criteria for sustainable socio-economic structures of local and regional municipalities.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
No. 58,
2008
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Technologie- und Gründerzentren im Lichte von Diversifizierung versus Spezialisierung
Michael Schwartz, Christoph Hornych
IWH Discussion Papers,
No. 7,
2008
Abstract
In Germany, a growing tendency can be observed to focus business incubators (BIs) and technology centers and their respective support elements and processes as well as the selection criteria applied by the incubator management on firms from solely one sector or few but complementary sectors and their specific needs and requirements. These are called specialized business incubators (SBIs). Despite the increasing importance of specialization strategies of business incubators as local and regional policy instruments, there are no reliable empirical examinations of the specifics, and advantages in particular, of SBIs compared to more diversified BIs. On the basis of survey-data, that comprises responses from 161 actual firms incubated in 13 diversified BIs and 13 specialized BIs in Germany, this study investigates the mechanisms within the specific context of specialized BIs and their value-added contribution versus the more diversified incubation model. For the first time, this study provides large-scale empirical evidence concerning the effects of adopting a specialization strategy in the context of business incubation.

Export Promotion Needs the Disclosure of Industrial Potentials – A Case Study for the Federal State of Thuringia
Udo Ludwig, Brigitte Loose, Cornelia Lang
Wirtschaft im Wandel,
No. 5,
2008
Abstract
In countries and regions with weak domestic markets, the orientation towards external markets plays an important rule. This applies even more for economies emerging from the transformation process from a state to a market economy with a small export sector and a continuous decline in the number of residents. The federal state Thuringia presents such an example. There is still a large gap in exports compared to Germany as a whole. The paper deals with the role of exports in economic development and economic measures to increase the export activities of small and medium-sized companies (SMEs) in Thuringia. The study is based on a survey among SMEs in Thuringia on the performance of exporters and non-exporters. One of the main findings shows that export promotion was important only for one among three exporting companies during the last three years. That speaks for the confidence of the firms in their own power. The most measures used to implement or advance export activities are participation in a fair, information sessions on foreign markets and two general instruments to support companies: investment and innovation stimulation. As a result, economic measures make sense, but it should not depend on the age or the size of a company. Besides, the support should not only be given by department of foreign trade, but also by other departments. Finally, especially newcomers should be supported to entry foreign markets.

Regional origins of employment volatility: evidence from German states
Claudia M. Buch
CES IFO Working Paper No. 2296,
2008
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

Leaders and Laggards – An Analysis of Regional Growth Patterns in East Germany 1996 – 2005
Alexander Kubis, Mirko Titze, Matthias Brachert
Wirtschaft im Wandel,
No. 4,
2008
Abstract
Since the half of the 1990s, a heterogeneous development of East Germany NUTS 3 regions has taken place. Some of these regions could increase their competitiveness and regional employment. Otherwise, some regions do exist with less positive economic developments.
This article tries to contribute to this discussion. With the help of productivity and employment growth rates from 1996 to 2005, we create a regional classifications scheme for East Germany. Four types can be identified: Growth Regions, Weak Growth Regions, Regions in Transition, Stagnant Regions. Further, we demonstrate that each of these regions is undergoing specific patterns of structural change. Growth Regions (above average productivity growth and employment growth) benefit from positive developments both in the manufacturing and service sector. Additional research indicates that there is a need for an industrial base which contributes to a sound service sector. Thereby, spatial proximity of these sectors seems to be elementary for the above average development of this type of regions.

The Transition to Post-industrial BMI Values Among US Children
John Komlos, Ariane Breitfelder, Marco Sunder
NBER Working Paper No. 13898,
No. 13898,
2008
Abstract
In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some historical BMI values for comparison. The increase in BMIZ values during the period considered was on average 1.3σ (95% CI: 1.16σ; 1.44σ) among black girls, 0.8σ for black boys, 0.7σ for white boys, and 0.6σ for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black females, the rate of increase tended to accelerate among all four groups born in the mid-1950s to early-1960s with the contemporaneous spread of TV viewing. The rate of increase levelled off somewhat thereafter. There is some indication that among black boys and white girls born after c. 1990 adiposity has remained unchanged or perhaps even declined. The affects of the IT revolution of the last two decades of the century is less evident. Some regional evidence leads to the speculation that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We infer that the incremental weight increases are associated with the labor-saving technological developments of the 20th century which brought about many faceted cultural and nutritional revolutions.
