Abstract
In 2006, Russian economic growth was once more driven by surging private consumption and investment. Thanks to the high energy prices, the boom in export revenues continued. Enterprises had increased earnings from oil and other natural resources, and also the government budget had high surpluses. Both led to significantly faster growth of investments. Construction sector and industry benefited from rising investments, but domestic demand of investment and consumption also covered by increased imports. The importance of the energy sector for the economy remains high. But sustainable long-term growth will require even more investment as well as substantial improvements in economic restructuring.

Gesamtwirtschaftliche Effekte der Förderung regenerativer Energien, insbesondere der Biomasse - Eine kritische Beurteilung vor dem Hintergrund modelltheoretischer Konzeptionen

Zeitschrift für Umweltpolitik und Umweltrecht 2/2006,
No. 2,

Abstract
Renewable energies are largely promoted in the Federal Republic of Germany by means of political instruments by the federal government as well as by the federal states. However, the effects of promoting renewable energies on growth and employment are politically controversial. On the part of the scientists, the macroeconomic effects of the promotion of renewable energies were already analysed in different studies by various authors. At first sight, even the scientific results do not allow definite conclusions. The reasons for this may be seen in the diversity of the applied empirical methods and models with respect to their closeness and the model assumptions. Against the background of these difficulties, the aim of this paper is to discuss the general problems of macroeconomic policy analyses, to formulate methodical model requirements and to examine important existing scientific studies with respect to these requirements and to evaluate their results.

Abstract
Der Besuch von Frau Merkel in Moskau erfolgte im Lichte einer neuen Sachlichkeit, die auch auf die Beziehungen zu Rußland als Energielieferant ausstrahlen sollte. Dies ist nach den Turbulenzen, welche die russische Energiepolitik letztens ausgelöst hatte, notwendig. Denn wir sind in einem Zwiespalt: Einerseits ist Rußland ein attraktiver und wachsender Absatzmarkt für die deutsche Industrie. Diesem Interesse stehen jedoch andererseits zwei Barrieren gegenüber. Die eine ist die Nichtmitgliedschaft Rußlands in der Welthandelsorganisation (WTO). Dadurch werden deutsche Exporte und Direktinvestitionen behindert. Die zweite Barriere ist die Energiepolitik Rußlands, und zwar aus ökonomischen wie auch politischen Gründen. Zwar mag die russische Regierung die Versorgung der Haushalte und Industrie mit billiger Energie mit dem Argument sozialer Stabilität verteidigen.

The Economics of Restructuring the German Electricity Sector
Christian Growitsch, Felix Müsgens
Zeitschrift für Energiewirtschaft,
No. 3,
2005
Abstract
The debate about the development of German electricity prices after the liberalization of energy markets in 1998 raises the question of failures in market restructuring. However, a general statement would be misleading for two main reasons. Firstly, the price development, analyzed for the exemplary case of household prices, 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%).

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

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%).

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.

Konjunktur aktuell: Konjunkturausblick des IWH für 2005 - Deutsche Binnenkonjunktur zieht allmählich nach
Der kräftige Aufschwung in der Weltwirtschaft musste sich im Lauf des Jahres 2004 infolge der drastischen Verteuerung von Energie und Rohstoffen einem Belastungstest stellen. War die Verlangsamung des konjunkturellen Auftriebs ohnehin durch die nachlassende Dynamik der Produktion in den Wachstumszentren USA und China angelegt, so verstärkte sich dadurch die Abschwächung noch. Anfang 2005 werden jedoch die negativen Folgen des Ölpreisanstiegs abklingen.
The Contestable Markets Theory - Efficient Advice for Economic Policy
Christian Growitsch, Thomas Wein
External Publications,

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.
