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.

Network Access Charges, Vertical Integration, and Property Rights Structure

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.

Determinants and Effects of Foreign Direct Investment: Evidence from German Firm-Level Data

No. 41,
2005
Abstract
Foreign direct investment is an essential aspect of ‘globalization’ yet its empirical determinants are not well understood. What we do know is based either on poor data for a wide range of nations, or good data for the US and Swedish cases. In this paper, we provide evidence on the determinants of the activities of German multinational firms by using a newly available firm-level data set from the Deutsche Bundesbank. The specific goal of this paper is to demonstrate the relative role of country-level and firm-level determinants of foreign direct investment. We focus on three main questions: First, what are the main driving forces of German firms’ multinational activities? Second, is there evidence that sector-level and firm-level factors shape internationalization patterns? Third, is there evidence of agglomeration effects in the foreign activities of German firms? We find that the market access motive for internationalization dominates. Firms move abroad mainly to gain better access to large foreign markets. Cost-saving motives, however, are important for some manufacturing sectors. Our results strongly suggest that firm-level heterogeneity has an important influence on internationalization patterns – as stressed by recent models of international trade. We also find positive agglomeration effects for the activities of German firms that stem from the number of other German firms that are active on a given foreign market. In terms of lessons for economic policy, our results show that lowering barriers to the integration of markets and encouraging the formation of human capital can promote the activities of multinational firms. However, our results related to the heterogeneity of firms and agglomeration tendencies show that it might be difficult to fine-tune policies directed at the exploitation of synergies and at the creation of clusters of foreign firms.

The influence of Vertical Integration and Property Rights on Network Access Charges in the German Electricity Markets
Christian Growitsch, Thomas Wein
Externe Publikationen,
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.

Economic Opening Up and Growth in Russia: Finance, Trade, Market Institutions, and Energy,
2004
Abstract
The transition to a market economy in the former CMEA area is more than a decade old and one can clearly distinguish a group of relatively fast growing countries — including Estonia, Poland, the Czech Republic, Hungary and Slovenia — and a majority of slowly growing economies, including Russia and the Ukraine. Initial problems of transition were natural in the sense that systemic transition to a market economy has effectively destroyed part of the existing capital stock that was no longer profitable under the new relative prices imported from world markets; and there was a transitory inflationary push as low state-administered prices were replaced by higher market equilibrium prices. Indeed, systemic transformation in eastern Europe and the former Soviet Union have brought serious transitory inflation problems and a massive transition recession; negative growth rates have continued over many years in some countries, including Russia and the Ukraine, where output growth was negative throughout the 1990s (except for Russia, which recorded slight growth in 1997). For political and economic reasons the economic performance of Russia is of particular relevance for the success of the overall transition process. If Russia would face stagnation and instability, this would undermine political and economic stability in the whole of Europe and prospects for integrating Russia into the world economy.

Macroeconomic Modelling of the German Economy in the Framework of Euroland
Rüdiger Pohl, Heinz P. Galler
Schriften des IWH,
No. 11,
2002
Abstract
An attempt to develop a new macroeconometric model for Germany is confronted with several questions that range from the general rationality of such an approach to specific problems of an appropriate model structure. One important aspect of this discussion is the introduction of the Euro as a common currency of the European monetary union. This institutional change may result in structural breaks due to changing behavior of economic agents. In addition, the definition of the spatial unit that is appropriate for modelling becomes a problem. Additional problems come from the introduction of the European Single Market and the increasing international economic integration not only within the European union but also beyond its borders. And in the case of Germany, the unification of the West and the East demand special attention. Last but not least, the harmonization of national accounting for the member states of the European Union has to be dealt with. Thus, the introduction of the Euro as a common currency is just one problem besides others that must be addressed.

Border regions in the European integration process – Results of an IWH conference -
Franz Barjak, Gerhard Heimpold
Wirtschaft im Wandel,
No. 5,
2000
Abstract
Den Folgen der Integration für die wirtschaftliche Entwicklung in Grenzregionen widmete sich eine Tagung des IWH am Beispiel der deutsch-polnischen Grenzregion, in der sich derzeit die Wirkungen der schrittweisen Grenzöffnung mit strukturellen Anpassungsproblemen im Zuge der Transformation überlagern. In der Regionalpolitik erweisen sich vor allem Maßnahmen als integrationsfördernd, die die Barrierewirkungen der Grenzlage beseitigen. Politikmaßnahmen, die dagegen auf Faktorpreisunterschieden und eingeschränkter Faktormobilität aufbauen, z.B. grenznahe oder grenzüberschreitende Gewerbeparks oder Sonderwirtschaftszonen, stehen eigentlich längerfristig dem Integrationsgedanken entgegen.

Industry subsidies in EU: Dangers for realistic economic integration
Vera Dietrich
Wirtschaft im Wandel,
No. 3,
1998
Abstract
Die Subventionierung der nationalen Industrien durch die EU-Mitgliedstaaten stellt ein Hindernis für die wirtschaftliche Integration in der Europäischen Union dar. Sowohl unter Wettbewerbsgesichtspunkten als auch im Hinblick auf einen Abbau der Einkommensdisparitäten zwischen den Mitgliedsländern ist dabei kritisch zu bewerten, daß die Subventionsintensität offensichtlich von der Finanzkraft der jeweiligen Mitgliedstaaten beeinflusst wird. Gleichzeitig steigt die Neigung zur Gewährung von kurzfristigen Ad-hoc-Beihilfen, deren Genehmigung zum Teil unter Ausübung politischen Drucks erwirkt wird. Vor dem Hintergrund zunehmender Beschäftigungsprobleme und einer Erhöhung der Wettbewerbsintensität in der Industrie durch eine Ost-Erweiterung der EU ist damit zu rechnen, daß beide Tendenzen sich verstärken werden. Verlierer einer solchen Entwicklung wären die wirtschaftlich schwächeren Mitglieder, mit der Folge sich verstärkender regionaler Disparitäten im europäischen Wirtschaftsraum. Die politische Unabhängigkeit der Beihilfenkontrolle nach dem Vorbild der künftigen Europäischen
Zentralbank stellt daher eine wichtige Voraussetzung zur Realisierung der Integrationsgewinne
dar.
