Foreign Subsidiaries in the East German Innovation System – Evidence from Manufacturing Industries
Jutta Günther, Björn Jindra, Johannes Stephan
IWH Discussion Papers,
No. 4,
2008
Abstract
This paper analyses the extent of technological capability of foreign subsidiaries located in East Germany, and looks at the determinants of foreign subsidiaries’ technological sourcing behaviour. The theory of international production underlines the importance of strategic and regional level variables. However, existing empirical approaches omit by and large regional level factors. We employ survey evidence from the “FDI micro data- base” of the IWH, that was only recently made available, to conduct our analyses. We find that foreign subsidiaries are above average technologically active in comparison to the whole East German manufacturing. This can be partially explained by the industrial structure of foreign direct investment. However, only a limited share of foreign subsidiaries with R&D and/or innovation activity source technological knowledge from the East German innovation system. If a subsidiary follows a competence augmenting strategy or does local trade, it is more likely to source technological knowledge locally. The endowment of a region with human capital and a scientific infrastructure has a positive effect too. The findings suggest that foreign subsidiaries in East Germany are only partially linked with the regional innovation system. Policy implications are discussed.

Determinants of Female Migration – The Case of German NUTS 3 Regions
Alexander Kubis, Lutz Schneider
IWH Discussion Papers,
No. 12,
2007
Abstract
Our study examines the regional patterns and determinants of migration flows of young women. At the NUTS-3 regional level, i.e. the district level (Kreise), the German internal migration flows of the year 2005 are explored. From descriptive statistics it can be seen that peripheral regions in East Germany face the strongest migration deficit with respect to young women, whereas agglomerations in West Germany but also in the East benefit from an intense migration surplus within this group. An econometric analysis of determinants of regional migration flows gives evidence of the importance of labour market, family-related and educational migration motives. Generally speaking, young women tend to choose regions with good income and job opportunities, in addition they seem to be attracted by regions enabling an appropriate balance between family and career. Furthermore the existence of excellent educational facilities is a significant influence for young women’s migration. This educationally motivated type of migration generates a long lasting effect on the regional migration balance, especially when the educational opportunities in the destination region are associated with adequate career perspectives for high qualified female graduates. In view of considerable losses due to migration, the study shows various options for action. An important course of action is to incorporate policy measures improving regional employment and income opportunities. Secondly, extending vocational and academic offers addressed to women seems to be a suitable way to stimulate women’s immigration. Moreover, enhancing the social infrastructure, which contributes to a satisfactory work life balance, might attract young women or at least reduce the number of them leaving a region.

Broadband Investment and the Threat of Regulation: Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
Review of Network Economics,
2007
Abstract
Die Investitionen seitens der Deutschen Telekom in die VDSL-Technologie wurden von ihr an die Bedingung der Regulierungsfreiheit geknüpft. Um eine Regulierungsstrategie zu entwickeln, die gleichzeitig Investitionen ermöglicht und monopolistische Preise verhindert, wird in diesem Beitrag die Investitionsentscheidung unter Regulierungsandrohung spieltheoretisch modelliert. Es wird gezeigt, daß die bloße Drohung einer Intervention durch den Regulierer Übergewinne verhindern kann. Der Regulierer kann die Investitionsentscheidung und den Preis des Investors über Signale über die Wahrscheinlichkeit des Eingreifens und den eventuellen Regulierungspreis beeinflussen.

Local Government Control and Efficiency of the Water Industry: An Empirical Analysis of Water Suppliers in East Germany
Peter Haug
IWH Discussion Papers,
No. 3,
2007
Abstract
The paper deals with the effects of local governments’ interference with business affairs of publicly owned utilities. A partial model is presented to illustrate the consequences of “democratic control” for the public managers’ effort and the efficiency of local public production. To check the theoretical results empirically, a two-stage data envelopment analysis (DEA) is carried out for a sample of East German water suppliers. The organisational form is used as a measure for the degree of municipal control. The results of the OLS- and Tobit regression indicate an efficiency-enhancing effect of organisational forms with less distinctive control options for local politicians.

Local Public Utilities' Profits and Municipal Expenses in Germany: An Empirical Analysis
Peter Haug, Birger Nerré
Proceedings of the 99th Annual Conference on Taxation (November 16-18), Washington DC,
2006
Abstract
The article offers information on profits and municipal expenses of local public utilities in Germany. It reveals that cities and municipalities faced rising expenses over the last years and the only way for local governments to avoid budgetary bottlenecks is to postpone infrastructure investment and increase short-term borrowing. The countries municipalities tried to overcome such difficulties by increasing local public utilities' profits.

Network investment and the threat of regulation: avoiding monopoly or infrastructure extension

Wirtschaft im Wandel,
No. 5,

Abstract
Im Sommer 2005 gab die Deutsche Telekom ihre Pläne für den Aufbau eines neuen Glasfasernetzes bekannt. Sie formulierte gleichzeitig die Bedingung, daß dieses Netz weder preislich noch hinsichtlich der Nutzung durch andere Anbieter (Netzzugang) reguliert werden sollte. Um die Investitionen zu ermöglichen, einigte sich die große Koalition im Koalitionsvertrag darauf, das neue Netz von der ex-ante Regulierung auszunehmen und diese Regulierungsfreiheit im Telekommunikationsgesetz zu integrieren. Es stellt sich nun die Frage, wie die Investitionen ermöglicht und gleichzeitig Wohlfahrtsverluste durch Monopolgewinne verhindert werden können. Spieltheoretisch läßt sich zeigen, daß eine Regulierungsbehörde wie die für den deutschen Telekommunikationssektor zuständige Bundesnetzagentur mit steigender Unsicherheit über die erwarteten Kosten und Erträge einer Investition eine zunehmende Toleranz gegenüber Abweichungen von einem von ihr selbst ermittelten und festgelegten Regulierungspreis signalisieren sollte. Dann führt bereits allein Androhung eines regulatorischen Eingriffs zu tolerierbaren Preisen, ohne daß eine tatsächliche Preisregulierung vorgenommen werden muß. Zukünftig sollte die Bundesnetzagentur allerdings Informationsasymmetrien reduzieren und das optimale Niveau an Toleranz vermindern, um zu einem präziseren Interventionspreis und einer effektiveren Regulierungsandrohung zu kommen. Die Wirksamkeit einer solchen Regulierungsandrohung läßt allerdings deutlich nach, wenn der Gesetzgeber den Regulierer per Gesetz von der Nutzung dieses Instrumentes ausschließt. Vor diesem Hintergrund geht der jüngst verfaßte Beschluß der Bundesregierung vom 17. Mai 2006 zur Novelle des Telekommunikationsgesetzes ökonomisch in die richtige Richtung, wird aber in der tatsächlichen Rechtspraxis seine Anreizkompatibilität beweisen müssen.

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.
