IWH Discussion Papers,
No. 2,

Abstract
The aim of this paper is to analyze the technological activities of Central and Eastern European (CEE) economies and to compare them with the technological activities of other world regions. Using data from the EPO World Wide Statistical Database for the period 1980-2009 the analysis is based on counts of priority patent applications over time. In terms of priority patent applications, CEE reduced its technological activities drastically in absolute and per capita terms after 1990. The level of priority patent applications in this world region maintained more recently a stable level below the performance of EU15, South EU and the former USSR. In what concerns technological specialization, the results suggest a division of labor in technological activities among world regions where Europe, Latin America and the former USSR are mainly specializing in sectors losing technological dynamism in the global patent activities (Chemicals and/or Mechanical Engineering) while North America, the Middle East (especially Israel) and Asia Pacific are increasingly specializing in Electrical Engineering, a sector with strong technological opportunities.

Local Economic Structure and Sectoral Employment Growth in German Cities
Annette Illy, Michael Schwartz, Christoph Hornych, Martin T. W. Rosenfeld
Tijdschrift voor economische en sociale geografie,
No. 5,
2011
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on sectoral employment growth in German cities (“urban growth”). We test four elements simultaneously – sectoral specialisation, diversification of economic activities, urban size and the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. Our regression results show a U-shaped relationship between localisation economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former, a U-shaped relationship is found, whereas the effect is inversely U-shaped for the latter.

Im Fokus: Potenziale qualifizierter Zuwanderung nach Ostdeutschland
Alexander Kubis
Wirtschaft im Wandel,
No. 4,
2011
Abstract
Für die ostdeutsche Arbeitskräftenachfrage lässt sich auf Basis der demographischen Prognosen ein Engpass im Bereich des mittleren und hohen Qualifikationsniveaus vorhersagen, der nicht allein durch ein bisher nicht ausgeschöpftes Arbeitskräfteangebot gedeckt werden kann, sondern auch einer qualifizierten Zuwanderung bedarf. Der Beitrag beschreibt die verschiedenen möglichen Wege qualifizierter Zuwanderung nach Ostdeutschland:
internationale Zuwanderung von außerhalb und innerhalb der Europäischen Union sowie nationale Binnenzuwanderung aus Westdeutschland. Ein Schwerpunkt untersucht die Auswirkungen der vollständigen Arbeitnehmerfreizügigkeit für polnische Staatsbürger zum 1. Mai 2011. Die Ergebnisse zeigen, dass Emigranten aus dem Zusammenspiel von wirtschaftlicher Leistungsfähigkeit und bestehenden Netzwerken in der Zielregion Vorteile ziehen. Deshalb werden voraussichtlich vor allem die westdeutschen Wirtschaftszentren von einem ansteigenden polnischen Migrationsstrom profitieren. Die ostdeutschen Länder werden vielfach nur als Durchgangsregionen fungieren.

The Identification of Industrial Clusters – Methodical Aspects in a Multidimensional Framework for Cluster Identification
Mirko Titze, Matthias Brachert, Alexander Kubis
Abstract
We use a combination of measures of spatial concentration, qualitative input-output analysis and innovation interaction matrices to identify the horizontal and vertical dimension of industrial clusters in Saxony in 2005. We describe the spatial allocation of the industrial clusters and show possibilities of vertical interaction of clusters based on intermediate goods flows. With the help of region and sector-specific knowledge interaction matrices we are able to show that a sole focus on intermediate goods flows limits the identification of innovative actors in industrial clusters, as knowledge flows and intermediate goods flows do not show any major overlaps.

Is there a Superior Distance Function for Matching in Small Samples?
Eva Dettmann, Claudia Becker, Christian Schmeißer
Abstract
The study contributes to the development of ’standards’ for the application of matching algorithms in empirical evaluation studies. The focus is on the first step of the matching procedure, the choice of an appropriate distance function. Supplementary o most former studies, the simulation is strongly based on empirical evaluation ituations. This reality orientation induces the focus on small samples. Furthermore, ariables with different scale levels must be considered explicitly in the matching rocess. The choice of the analysed distance functions is determined by the results of former theoretical studies and recommendations in the empirical literature. Thus, in the simulation, two balancing scores (the propensity score and the index score) and the Mahalanobis distance are considered. Additionally, aggregated statistical distance functions not yet used for empirical evaluation are included. The matching outcomes are compared using non-parametrical scale-specific tests for identical distributions of the characteristics in the treatment and the control groups. The simulation results show that, in small samples, aggregated statistical distance functions are the better
choice for summarising similarities in differently scaled variables compared to the
commonly used measures.

Urban Growth in Germany – The Impact of Localization and Urbanization Economies
Christoph Hornych, Michael Schwartz, Annette Illy, Martin T. W. Rosenfeld
IWH Discussion Papers,
No. 19,
2009
Abstract
This study examines the impact of localization and urbanization economies as well as the impact of city size on urban growth in German cities from 2003 to 2007. Although, from a theoretical perspective, agglomeration economies are supposed to have positive impacts on regional growth, prior empirical studies do not show consistent results. Especially little is known about agglomeration economies in Germany, where interregional support policy and the characteristics of the federal system are further determinants of urban growth. The results of the econometric analysis show a U-shaped relationship between specialization and urban growth, which particularly holds for manufacturing industries. We do not find evidence for the impact of Jacobs-externalities; however, city size shows a positive (but decreasing) effect on urban growth.

EU Eastern Enlargement and Structural Change: Specialization Patterns in Accession Countries and Economic Dynamics in the Single Market

Abstract
This paper analyses key issues of structural change and specialization patterns in the economies of an enlarged European Union. In all transition countries we observe a shift from the agricultural and industrial sector towards the service sector in terms of employment and productivity; however, in some countries a reindustrialisation drives is observed in a late transition stage. While some countries namely the Czech Republic, Hungary, Slovakia, Poland, Estonia and Slovenia, have improved their productivity especially in medium-technology-intensive industries and may advance on the technological ladder, others remain unchanged and seem to get locked in labour-intensive industrial sectors. In the context of EU-enlargement, we expect trade creation – going along with a rise of intra-industry trade – and higher FDI-activities. Countries will have to adjust along the logic of comparative advantage, however, technological upgrading and human capital formation are fields in which government can stimulate the direction of comparative advantage. According to the Gerschenkron-hypothesis the accession countries have an “advantage of backwardness. Since accession countries have a low R&D-GDP ratio in the early transition stage rising government expenditures on research and development plus higher education is crucial. We expect the EU-15 countries in general to benefit from enlargement but gains will be asymmetric across countries: economic geography matters. Austria, Germany, the Scandinavian countries, the Netherlands, Italy and France are likely to profit more than the other members of EU-15. Germany and Austria additionally play a particularly crucial role as origins of FDI. Future research should focus on the speed and the scope of structural adjustment.

A glimpse on sectoral convergence of productivity levels
Gerald Müller
IWH Discussion Papers,
No. 133,
2001
Abstract
This paper examines the presence of sectoral convergence of labor productivity between 14 OECD countries. Using the OECD International Sectoral Data Base (ISDB), the paper looks at the developments within 12 distinct sectors during the period 1970-1995. The change of the coefficients of variance suggests that there is strong sectoral convergence within most service sectors while the evidence of convergence for Manufacturing as well as for Communication is rather weak. These findings are in line with most studies undertaken on this subject so far. It is concluded that economic theories at hand to explain growth and convergence (or divergence respectively) are of different importance for the sectors concerned. While models of the New Growth Theory seemed to be useful to explain growth mechanisms within Manufacturing and Communication, traditional models seemed to apply to most other sectors.
