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“

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

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.

Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
IWH Discussion Papers,
No. 7,
2006
Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

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.

Essays on Network Regulation – Theoretical and Empirical Evidence from the Electricity Supply Industry

Abstract
Mit dem Etablieren des gemeinsamen Europäischen Binnenmarktes im Laufe der 80er und 90er Jahre des vergangenen Jahrhunderts und dem damit verbundenen Wegfall von Handelsbarrieren und anderen Wettbewerbshemmnissen rückte die Liberalisierung sogenannter Netzindustrien in den Fokus der Europäischen Politik. Die Deregulierung solcher Sektoren mit physischer Netzinfrastruktur, insbesondere der Märkte für Strom, Gas, Telekommunikation und Schienenverkehr wurde zu einem wesentlichen Aspekt des Ziels der Förderung von Wettbewerb in der Europäischen Ökonomie. Die Einführung wettbewerblicher Strukturen in die ehemalig monopolistischen Netzindustrien bedingte die Notwendigkeit wettbewerbspolitischer Reformen auf nationaler und Europäischer Ebene. Insbesondere die Sicherstellung gleicher Wettbewerbsbedingungen und der Schutz der Verbraucher vor Marktmachtmißbrauch durch die etablierten Anbieter rückte in den Fokus der Wirtschaftspolitik und führte zum Aufbau sektorspezifischer Regulierungsregime. Diese unterscheiden sich deutlich sowohl sektoral wie im Hinblick auf nationale Ordnungsrahmen hinsichtlich ihrer Rahmenbedingungen, ihrer Methoden, ihrer Struktur und ihrer ökonomischen Wirkung. Der Austausch und die Übertragung von Erkenntnissen und Erfahrungen und die kontinuierliche Verbesserung bestehender institutioneller Arrangements sollte daher ein bedeutender Aspekt ökonomischer Forschung und staatlicher Wirtschaftspolitik sein. Die hier vorliegende Sammlung energieökonomischer Aufsätze zielt auf eben jenen Erkenntnistransfer ab. Dazu wird in den ersten beiden Artikeln ein spezifisches Regulierungsregime, der sogenannte verhandelte Netzzugang, und die damit verbundenen Erfahrungen aus dem deutschen Elektrizitätsmarkt vorgestellt. Ein dritter Aufsatz beschäftigt sich mit der Versorgungsqualität in Netzsektoren am Beispiel lokaler Stromverteilnetzbetreiber in einem europäischen Vergleich.

Quality of Service, Efficiency, and Scale in Network Industries: An Analysis of European Electricity Distribution

No. 3,
2005
Abstract
Quality of service is of major economic significance in natural monopoly infrastructure industries and is increasingly addressed in regulatory schemes. However, this important aspect is generally not reflected in efficiency analysis of these industries. In this paper we present an efficiency analysis of electricity distribution networks using a sample of about 500 electricity distribution utilities from seven European countries. We apply the stochastic frontier analysis (SFA) method on multi-output translog input distance function models to estimate cost and scale efficiency with and without incorporating quality of service. We show that introducing the quality dimension into the analysis affects estimated efficiency significantly. In contrast to previous research, smaller utilities seem to indicate lower technical efficiency when incorporating quality. We also show that incorporating quality of service does not alter scale economy measures. Our results emphasise that quality of service should be an integrated part of efficiency analysis and incentive regulation regimes, as well as in the economic review of market concentration in regulated natural monopolies.

Negotiated Third Party Access - an Industrial Organisation Perspective
Christian Growitsch, Thomas Wein
European Journal of Law and Economics,
2005
Abstract
In the course of the liberalization of European energy markets, the German government opted – diverging from all other European countries – for Negotiated Third-Party Access. In this article we analyze if, theoretically, this institutional regime can be superior to regulation. We review empirically whether certain aspects of the actual implementation, in particular publication of the network access charges for each network supplier, facilitated or inhibited competition. In the first place we reconsider previous research, showing that NTPA can – under certain conditions – be economically effective. Our empirical analysis shows that the duty of publishing access charges supported market transparency and imposed a regulatory threat, particularly to suppliers with significantly above-average charges. On the other hand observable price adjustments over time serve as an indicator of tacit collusion. Although the expensive suppliers cut their prices, the cheaper ones raised theirs.

Abstract
According to theoretical implications the succes of enterprises benefits from co-operation and integration into networks. Enterprises of the biotechnology sector in particular have a high propensity to build up co-operations. Estimations of the growth of firms using co-operation-based and non-co-operation-based factors as independent variables reveal a significantly positive influence of the propensity of co-operation as well as networking. In this regard scientific institutions and universities located in geographical proximity of firms play an important role. From this analysis it can be generalized and concluded, concerning other industries too, that networks emerge automatically under certain conditions. Nevertheless their creation and development should be encouraged, e.g. by efficiency incentives for public research and education of universities as well as an intensification of co-operation and networking between the scientific and the corporate sector. This can promote the technology and human capital transfer.
