No. 3,

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.

An analysis of household electricity price developments in Germany since liberalization
Christian Growitsch, Felix Müsgens
Externe Publikationen,
2005
Abstract
Despite the liberalization of energy markets in 1998, household electricity prices in 2004 are nearly the same as 1998, indicating a failure of market restructuring. However, such a general consideration is misleading for two main reasons. Firstly, the price development shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs. These decreases have been mostly compensated by a significant increase in taxes and subsidies (+56%).

Technological capability of foreign and West German investors in East Germany
Jutta Günther
IWH Discussion Papers,
No. 189,
2004
Abstract
Foreign direct investment (FDI) plays an important role for countries or regions in the process of economic catching-up since it is assumed – among other things – that FDI brings in new production technology and knowledge. This paper gives an overview about the development of FDI in East Germany based on official data provided by the Federal Bank of Germany. The investigation also includes a comparison of FDI in East Germany to Central East European countries. But the main focus of the paper is an analysis of the technological capability comparing majority foreign and West German owned firms to majority East German owned firms. It shows that foreign and West German subsidiaries in East Germany are indeed characterized by superior technological capability with respect to all indicators looked at (product innovation, research & development, organizational changes etc.).

Investment, Financial Markets, New Economy Dynamics and Growth in Transition Countries

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.

A Study of the Competitiveness of Regions based on a Cluster Analysis: The Example of East Germany
Franz Kronthaler
IWH Discussion Papers,
No. 179,
2003
Abstract
This paper examines whether some East German regions have already achieved the same economic capability as the regions in West Germany, so that they are on a competitive basis with the West German regions and are able to reach the same economic level in the long run. If this is not the case, it is important to know more about the reasons for the economic weakness of the East German regions twelve years after unification.
The study is based on a cluster analysis. Criteria for the cluster formation are several economic indicators, which provide information about the economic capability of regions. The choice of the indicators is based on a review of results of the theoretical and empirical literature on the new growth theory and new economic geography.
The results show that most of the East German regions have not yet reached the economic capability and competitiveness of their West German counterparts so that they - from the viewpoint of the new growth theory and the new economic geography - are not in the position to reach the same economic level. According to these theories economic disadvantages are most notably the consequences of less technical progress, a lack of entrepreneurship and fewer business concentration. Under these points it is especially noteworthy that young well educated people leave these East German regions so that human capital might will turn into a bottle-neck in the near future. Only a few regions in East Germany - those with important agglomerations - are comparable to West German regions that are characterised by average capability and competitiveness, but not to those with above average economic capability and competitiveness. Even those more advanced East German regions still suffer from a slower technical progress.
There are important policy implications based on these results: regional policy in East Germany was not able to assist raising all regions to a sufficient level of competitiveness. It may be more effective to concentrate the regional policy efforts on a selection of important agglomerations. This has also strong implications for the EU regional policy assuming that the accession countries will have similar problems in catching up to the economic level of the EU as have the East German regions.

IWH early warning indicators for financial crises in Central and Eastern Europe: Risk potential remains low
Ibolya Mile
Wirtschaft im Wandel,
No. 8,
2003
Abstract
Die aktuelle Analyse der Frühwarnindikatoren des IWH signalisiert ein weiterhin geringes Risiko für den Ausbruch von Finanzkrisen in den mittel- und osteuropäischen Beitrittsländern. Die Berechnungen bestätigen die positiven Erwartungen über die Stabilität der Finanzmärkte in dieser Region, die sich bereits in der vorangegangenen Untersuchung angedeutet hatten. Doch in einigen Bereichen, wie auf dem fiskalischen Gebiet, besteht für die Mehrzahl der Länder weiterhin wirtschaftspolitischer Handlungsbedarf. Im März 2003 hat auch Kroatien einen Beitrittsantrag an die Europäische Kommission gestellt. Deshalb wurde Kroatien erstmalig mit in die Untersuchungen des IWH zur Bestimmung von Risikopotenzialen für Finanzkrisen einbezogen. Die Frühwarnindikatoren zeigen hier ein ähnliches Muster wie das der anderen mittel- und osteuropäischen Staaten.

Fallen risk potential for financial crises and improved perspectives for 2003/2004 in Central and Eastern Europe
Martina Kämpfe, Ibolya Mile
Wirtschaft im Wandel,
No. 4,
2003
Abstract
Die aktuellen Berechnungen der Frühwarnindikatorenanalyse ergaben eine Verringerung des Risikopotenzials für Finanzkrisen für alle Volkswirtschaften Mittel- und Osteuropas mit Ausname von Ungarn. Hier hat sich der Konflikt zwischen einer expansiven Fiskalpolitik und einer restriktiven Geldpolitik zuletzt zugespitzt. Die Zunahme des Bruttoinlandsprodukts schwächte sich 2002 ab, lag aber mit Ausnahme von Polen und Tschechien bei über 3%. Dieser Anstieg wurde vorrangig von der Binnennachfrage und weniger vom Export getragen. Im Rahmen der Binnennachfrage nahm der private Konsum durchgängig zu, während der öffentliche Konsum und die Investitionstätigkeit eher uneinheitlich in der Region ausfielen. Für das Jahr 2003 ist insgesamt mit einer leichten Verstärkung des BIP-Zuwachses auf 3,4% in Mitteleuropa und dem Baltikum und 3,7% in Russland zu rechnen. Die Inflation wird sich im laufenden Jahr wegen des Ölpreisanstiegs in den meisten Ländern wieder etwas beschleunigen, im Jahr 2004 dagegen sinken. Im Jahr 2004 wird das Wirtschaftswachstum weiter zunehmen.
