Abstract
We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region. Different measures and estimation approaches lead to rather similar assessments. We find that both spillovers within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector R&D in the respective region. It is not the mere presence and size of public research institutions, but rather the intensity of interactions between private and public sector R&D that leads to high RIS efficiency. We find that relationship between the diversity of a regions’ industry structure and the efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.

Economic 'Clusters' in East Germany: Evidence on the Location and the Characteristics of Spatially Concentrated Industries
Martin T. W. Rosenfeld, Peter Franz, Gerhard Heimpold
Post-Communist Economies,
No. 1,
2007
Abstract
The contribution provides empirical findings, which regions in East Germany show spatially concentrated industries possessing ”cluster” qualities. The latter are regarded as being existent if spatially concentrated industries coincide with networking activities and innovative competences. The findings reveal that spatially concentrated industries possessing the qualities sketched are relatively rare, and they are, if existent, primarily located in the East German agglomerated spaces. This in mind, the article draws the conclusion, that spreading regional policy schemes by the “watering can principle” should be avoided. Instead, the resources should be concentrated on locations where spatially concentrated industries are existent. Networks and innovative competences should be strengthened there.

Mikroökonometrische Evaluation der ökonomischen Wirkungen betrieblicher Mitbestimmung - Möglichkeiten und Grenzen des Matching-Ansatzes
Birgit Schultz
Jahrbücher für Nationalökonomie und Statistik,
No. 5,
2006
Abstract
The evaluation of economic effects of workers participation is not simple from the methodical point of view because of specific characteristics of establishments with works councils. Especially recent studies show contradictory results. In this study problems are pointed out, discussed, and options for solution are presented on the example of workers participation in East German establishments of industry and construction by the IAB-Establishment Panel.
An optimal matching-algorithm which supplies good matching-results for small samples to assign 'statistical establishment-twins' is applied. But by reason of very short primarily spells it can only calculate short time effects. Therefore, the matching method is additionally used to construct longer observation periods. By this new application establishments with recently founded works councils are matched with so called 'proxy establishments' with existing works councils. As a result short observation periods are prolonged and information about long-term effects can be given.
The effects on productivity, profitability and qualification level of employees show neither in short-term nor in long-term a significant impact on workers' participation.

Die Gestaltung der Wirtschaftsstruktur durch das Land Brandenburg - Eine kritische Analyse der Subventionszahlungen für die CargoLifter AG
Mirko Titze
Forum der Forschung. Wissenschaftsmagazin der Brandenburgischen Technischen Universität Cottbus,
No. 17,
2004
Abstract
The Government of the State of Brandenburg subsidised the company CargoLifter AG on the basis of the „new industrial policy“. Following this policy the government supports individually selected industries or companies. The „new industrial policy“ is supported by the strategic trade policy, which states that subsidising domestic companies in incomplete markets with declining average costs and high entry barriers can increase the welfare level of a particular region. The following article provides an analysis whether in the case of Cargo-Lifter the Government of the State of Brandenburg pursued an effective strategic trade policy. Moreover the article investigates particular problems of the strategic trade policy.

Where are the economic development cores of East Germany? Results of a survey of the focuses of branches, enterprise networks and innovative competence fields in the East German Regions

Regionale Strukturpolitik - quo vadis?, Informationen zur Raumentwicklung, Heft 9,
No. 9,

Abstract
The contribution presents the results of an empirical study conducted by the Halle Institute for Economic Research on behalf of the Federal Office for Building and Regional Planning. The study concerns the identification of “regional clusters” for all spatial planning regions in East Germany. As criteria to identify clusters, three components were taken into consideration: spatially concentrated industries, enterprise networks and innovative competence fields, whereas, for the purpose of identifying “clusters”, the networks and innovative competences have to show a co-incidence with the industry which is spatially concentrated. Cases of co-incidence of all three elements were categorised as economic development cores (or spots), i. e. as forms of spatially concentrated economic activities which show cluster-relevant qualities. For regions which possess economic development spots, the growth perspectives can be expected as more favourable in comparison with other regions. The findings show a particularly high concentration of economic development spots in the Berlin region as well as in the Federal States of Saxony and Thuringia, where the cities of Dresden, Leipzig, Erfurt and Chemnitz form delineating points within which a particularly high number of economic development spots are existent. As a consequence, the study might initiate a debate in favour of a stronger spatial concentration of regional policy measures instead of spreading the resources by “watering can principle”.

Vernetzung und einzelwirtschaftliche Effekte von Unternehmen der Kunststoff- und Biotechnologiebranche in Mitteldeutschland - eine Analyse am Beispiel der Clusterinitiativen „Chemie/Kunststoffe“ und „Biotechnologie/Life Sciences“
Walter Komar
IWH-Sonderhefte,
No. 2,

Abstract
According to theoretical implications the success of enterprises benefits from co-operation in clusters and networks. Studies of cluster and network processes show this for the industries chemistry/plastics and biotechnology/Life Sciences in Central Ger-many. Therefore enterprises which are organized in networks have better economic characteristics. Estimations of the productivity of firms using co-operation-based and non-co-operation-based factors as independent variables reveal a significantly positive influence of the propensity to co-operate as well as networking. In this regard scientific institutions and universities located in the region of firms play an important role. From this analysis it can be generalized and concluded, also concerning other industries, that networks emerge automatically under certain conditions. Nevertheless their creation and development should be encouraged, e.g. by efficiency strengthening of public research and university education as well as the intensification of co-operation and networking between the scientific and the corporate sector. This can promote the technology and human capital transfer.

Wie steht es in Mecklenburg-Vorpommern um die Ballung wirtschaftlicher Aktivitäten? - Eine Untersuchung unter besonderer Berücksichtigung der Städte des Landes
Gerhard Heimpold, Martin T. W. Rosenfeld
Rostocker Beiträge zur Regional- und Strukturforschung, Heft 18,
No. 18,
2006
Abstract
Urban and regional economics put great emphasis on urban spaces and, in general, on the importance of agglomeration forces, which is of great importance for the development perspectives of structurally weak regions. This in mind, the contribution investigates the extent and the structures of economic agglomeration characteristics, using the example of the cities in the Federal State of Mecklenburg-Vorpommern. In this context, the question is raised whether the potential given there might be better used to achieve economic progress. The contribution starts with a brief theoretical overview on the importance of agglomeration forces for urban and regional development. The empirical section comprises, first, an analysis how the cities under consideration are endowed with factors being regarded as important for economic growth; second, two essential elements of agglomeration of economic activities are investigated more in-depth: spatially concentrated industries and business networks. The investigation is based on a method which was already in use within an East-Germany wide study on Economic Development Spots (project on behalf of the Federal Office for Building and Regional Planning - BBR, finished in 2004). Finally, the contribution draws implications for the economic policy at the Laender level as well as at the municipal level.

Longterm development of return on assets – an empirical panel data analysis
Olaf Neubert
Wirtschaft im Wandel,
No. 5,
2006
Abstract
One of the basic propositions of economic theory is the fact that competition does not allow permanent very high or very low returns. But how can the permanent surplus gain of a monopolist be distinguished from innovation gains? In which markets is a regulatory interference necessary? Contrary to the static analysis, the concept of dynamic competition explicitly considers the temporal development of return and gain. An entrepreneur can achieve an advantage over the competitors through new products or new production processes. Hence arising innovation gains function as incentives for imitators to join the development which in turn leads to a reduction of the surplus gains. Thus, these gains are not contradictory to an effective competition. On the basis of annual balance sheets of German firms, this article analyses the temporal development of returns on assets. It is to evaluate whether the adaptation process assumed by Schumpeter that matches very high and very low gains with a longterm level can be confirmed, and how fast this process works. The average industry returns of the manufacturing industry show a convergence to a longterm level. During this process, an average of 40% of the deviation from the longterm level are melted every year. However, the analysis of company returns shows longterm differences. The adaptation rate of companies, 50%, is significantly higher compared to the industry value. The analysis of the connection between the adaptation rate and the longterm return level of companies proves that companies which face above-average competition strength obtain a higher longterm return level than other companies. When firms operate within markets with high stress of competition they do not achieve below-average returns but rather significantly above-average returns in the long term.

Economies of Scope in European Railways: An Efficiency Analysis
Christian Growitsch, Heike Wetzel
IWH Discussion Papers,
No. 5,
2006
Abstract
In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies – companies owning a network and providing transport services – argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realise economies of joint production and, thus, produce railway services on a higher level of efficiency. To determine whether joint or separate production is more efficient we apply a Data Envelopment Analysis super-efficiency bootstrapping model which relates the efficiency for integrated production to a virtual reference set consisting of the separated production technology. Our findings are that in a majority of European Railway companies exist economies of scope.
