Judit Hamar, Johannes Stephan
Foreign Direct Investment and Technology Transfer in Transition Countries: Theory – Method of Research – Empirical Evidence,
2005
Abstract
The second empirical analysis is based on a fieldwork project conducted between 2002 and 2003, which generated a large and unique database on 438 foreign subsidiaries in a selection of CEECs, namelay the Czech Republic, Estonia, Hungary, Poland, Slovakia and Slovenia. The field work was done between 2002 and 2003 by the use of a concise, two-page questionnaire, sent out to the largest foreign investment subsidiaries in the countries named. The questionnaire is presented in the Appendix to this book.In terms of methodology, the field work analysis focuses on the relationship between subsidiaries of MNEs which invested in CEE and their parent network, on the one hand, and the relationship between the subsidiaries and the local host economy, on the other.

Quality of Service, Efficiency, and Scale in Network Industries: An Analysis of European Electricity Distribution
Christian Growitsch, Tooraj Jamasb, Michael Pollitt
IWH Discussion Papers,
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.

Kooperation, Vernetzung und Erfolg von Unternehmen - die Biotechnologiebranche
Walter Komar
List Forum für Wirtschafts- und Finanzpolitik,
No. 2,
2005
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.

Network Access Charges, Vertical Integration, and Property Rights Structure
Christian Growitsch, Thomas Wein
Energy Economics,
No. 2,
2005
Abstract
After the deregulation of the German electricity markets in 1998, the German government opted for a regulatory regime called negotiated third party access, which would be subject to ex post control by the federal cartel office. Network access charges for new competitors are based on contractual arrangements between energy producers and industrial consumers. As the electricity networks are incontestable natural monopolies, the local and regional network operators are able to set (monopolistic) charges at their own discretion, limited only by their concerns over possible interference by the federal cartel office (Bundeskartellamt). In this paper we analyse if there is evidence for varying charging behaviour depending on a supplier`s economic independence (structure of property rights) or its level of vertical integration. For this purpose we hypothesise that incorporated and vertically integrated suppliers set different charges than independent utility companies. Multivariate estimations show a relation between network access charges and the network operator’s economic independence as well as level of vertical integration. On the low voltage level, for an estimated annual consumption of 1700 kW/h, vertically integrated firms set – as predicted by our hypothesis - significantly lower access charges than vertically separated suppliers, whereas incorporated network operators charge significantly higher charges compared to independent suppliers. There is insufficient evidence available to confirm these results for other consumptions or voltage levels.

Property networks of corporations as cause of abusive behaviour – A stock market analysis based on institutional economics
Makram El-Shagi
Applied Financial Economics Letters,
No. 5,
2005
Abstract
The present study deals with the fact that it seems as if executive boards have developed a self-service-mentality concerning the corporations they are meant to manage. The surprise about this is not the attempt of exploitation (rather the opposite would be surprising from an economic point of view) but the apparent absence of sanctions imposed by the owners. This study shows that this behaviour of corporations’ owners is at least to a main part due to the fact, that the reciprocal property of corporations prevents the exercise of certain property rights by the ‘true’ holders.

Enterprise networks in East Germany: Concentration on conglomerates.

Wirtschaft im Wandel,
No. 4,
2005
Abstract
Mit dem Vorhandensein von Unternehmensnetzwerken wird zumeist eine hohe Wettbewerbsfähigkeit der Wirtschaft in der betreffenden Region assoziiert. Eine erstmals flächendeckend für Ostdeutschland vorgenommene Bestandsaufnahme von Unternehmensnetzwerken zeigt eine erhebliche räumliche Ungleichverteilung von Netzwerkaktivitäten zugunsten der sächsischen Agglomerationsräume und zugunsten der Hauptstadtregion. Diese räumlichen Schwerpunkte der Netzwerkbildung lassen erkennen, dass sich Netzwerke am ehesten dort herausbilden und entwickeln, wo sie günstige „natürliche“ Entwicklungsbedingungen, d. h. vor allem eine hohe Dichte von Unternehmen und Wissenschaftseinrichtungen vorfinden. Dort können zugleich besonders intensive lieferund abnehmerseitige Verflechtungen vermutet werden. Dass die höher verdichten Regionen günstige „natürliche“ Bedingungen für die Etablierung von Netzwerken darstellen, wird auch an dem Umstand deutlich, dass in diesen Räumen besonders häufig Übereinstimmungen zwischen Unternehmensnetzwerken und regionalen Branchenschwerpunkten gegeben sind. Diese Übereinstimmungen können als vorteilhaft für die Regionalentwicklung angesehen werden, weil sie Indizien für das Vorhandensein von längerfristig gegebenen tendenziell nachhaltigen Netzwerkstrukturen sind. In dünn besiedelten, ländlich-peripheren Region ist dagegen die Zahl der Unternehmensnetzwerke zumeist gering, und sie werden sehr häufig nicht durch einen regionalen Branchenschwerpunkt begleitet. Es stellt sich die Frage nach der künftigen Bestandsfestigkeit der Unternehmensnetzwerke gerade in diesen Regionen mit geringer Verdichtung. Diese Frage erhält noch zusätzliches Gewicht, weil öffentliche Förderhilfen, die viele Netzwerke in Ostdeutschland erhalten, zeitlich befristet sind und daher die Fortexistenz der Netzwerke auch ohne Förderung eine besondere Herausforderung darstellt.

Declining population and rising costs for municipal services
Peter Haug
Wirtschaft im Wandel,
No. 11,
2004
Abstract
Population decrease in many East-German towns and municipalities does not only increase the stock of empty residential buildings. It also makes provision of network-related goods and services more costly. Considering public water and sewerage services as example, the article investigates empirically how costs of provision per inhabitant depend on population number and -density. Diverging from similar studies, spatial differences in distribution costs per inhabitant are calculated within the area of a case study municipality. The calculations are based on cost accounting data of the local provider. A central problem is the choice of an appropriate spatial key figure to allocate costs. The results indicate cost advantages in providing densely populated quarters with network-related services. Consequently, rising per-capita costs should be taken into account to a greater extent for the city conversion programmes in East Germany than they have been up to now.

The Contestable Markets Theory - Efficient Advice for Economic Policy
Christian Growitsch, Thomas Wein
External Publications,
2004
Abstract
During the nineties of the last century several formerly monopolistic markets (telecommunication, electricity, gas, and railway) have been deregulated in Germany based on European directives and theoretically inspired by the theory of contestable markets. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit possible without any costs, and the price adjustment lag exceeding the entry lag. Our analysis shows that if the incumbent reduces its prices slowly (high adjustment lag) and the market entry can be performed quickly (low entry lag), a new competitor will be able to earn back sunk costs. Therefore it is not necessary that all three conditions be complied with for potential competition to exist. Applying this „revised“ contestable market theory to the deregulated sectors in Germany, natural monopolies can be identified in telecommunication sections local loops and local/regional connection networks, in the national electricity grid and the regional/local electricity distribution networks, in the national and regional/local gas transmission/distribution sections, and in the railroad network. These sections are not contestable due to sunk costs, expected high entry lags and a probably short price adjustment lag. They are identified as bottlenecks, which should be regulated. The function of system operators in energy and railroad are closely related to the non-contestable monopolistic networks.

The influence of Vertical Integration and Property Rights on Network Access Charges in the German Electricity Markets
Christian Growitsch, Thomas Wein
External Publications,
No. 6,
2004
Abstract
German Electricity markets were deregulated in the late nineties of the last century. In contrast to other European countries, the German government enacted negotiated third party access instead of installing a regulation authority. Network access charges for new competitors are based on contractual arrangements between energy producers and industrial consumers, which specify the calculation schemes for access charges. Local and regional suppliers are nevertheless able to set (monopolistic) charges at their own discretion, restricted only by the possibility of interference competition authorities. While some of those suppliers have been acquired by one of the four Transmission System Operators and become vertically integrated, the majority is still independent public utility companies. In this paper we analyse if there is evidence for different charging behaviour depending on the supplier’s economic independence or its level of vertical integration. Controlling for other coefficients as the so called structural features and related cost differences as well as the influence of competition law suits, multivariate estimations show significantly lower access charges than vertically separated suppliers, whereas incorporated network operators charge significantly higher charges compared to independent suppliers for at least one typical case.
