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%).

Sachsen-Anhalt als Wirtschaftsstandort: Wie erfolgreich sind das Land und seine Regionen?
Martin T. W. Rosenfeld
Geographische Rundschau,
2005
Abstract
The article examines the economic performance and the conditions for future economic development in the German Land of Saxony-Anhalt. After the integration of Saxony-Anhalt into the market economy since 1989, strong structural changes have taken place. Nevertheless, agriculture, coal mining and the chemical industry as some of the traditional sectors of the Land’s economy have remained their importance. The weak points of the economy are the low number of entrepreneurs and a low tendency for innovations in the private sector. The Magdeburg region and the Halle region have better conditions for (inter-) national competitiveness than the Altmark region and the Dessau region. But the potentials of the urban centers Magdeburg and Halle are - as compared to other East German cities - not very strong. For improving the eonomic conditions, new instruments for stimulating entrepreneurship and for strengthening the position of the two urban centers should be installed. In addition, innovation activities of private firms could be improved by new linkages between the private sector and Saxony-Anhalt’s public research units.

Innovationskooperationen deutscher Unternehmen im europäischen und innerdeutschen Vergleich

Der Mittelstand an der Schwelle zur Informationsgesellschaft,
2005
Abstract
The study deals with innovation cooperation as a means to improve the competitiveness of enterprises. The empirical study compares the cooperation behaviour of innovative enterprises in Germany to other West European countries as well as between East and West Germany. The database used is the second Community Innovation Survey (CIS-2) of the EU. While German firms exhibit a cooperation frequency slightly below the average of the European Economic Area (EEA), enterprises in North European countries are by far most active with respect to cooperation frequency. The most important cooperation partner for firms in the EEA are other firms within the enterprise group, followed by suppliers and customers while German firms cooperate most frequently with universities. The comparative investigation of innovation cooperation in East and West Germany shows that East German firms cooperate more often than West German firms. However, a productivity advantage of cooperating firms against non-cooperating firms is only observable in West Germany. In East Germany, cooperating firms even exhibit a lower sales productivity than non-cooperating firms, which is explainable most probably through the fact that cooperation activities translate into productivity advantages only in the long run.

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.

Ein Jahr nach der EU-Osterweiterung - Erste Erfahrungen, Probleme, Aussichten
Herbert S. Buscher, Heiko Stüber
Zukunftsforum Politik Nr. 67,
2005
Abstract
The paper investigates possible employment effects of the EU-enlargement one year later. Special emphasis is put on the border regions to Poland and the Czeck Republic. Besides of legal restrictions the paper analyzes the possibilities of foreigners to work in Germany and to what extent these special regulations have been used. First preliminary results indicate that there are no large employment effects across both sides of the border. The paper concludes with a discussion of intended measures to protect German employees against competition from abroad.

East German construction firms on the average with small profits
Brigitte Loose, Udo Ludwig
Wirtschaft im Wandel,
No. 14,
2004
Abstract
The article is concerned with the cost and revenue situation in East and West German construction firms from the early 90´s onwards. As a result of the construction boom the East German firms could reduce the unit labour costs in the middle of the nineties under the corresponding western level. However, in the second half of the nineties they lost their advantage due to extremely decreasing productivity and rising unit labour costs. Nonetheless, on the average they earned profits, but in the observed last two years 2001 and 2002 the rate of return in the East remains smaller than in the West.

Progress reports from the project "Productivity Gap"
Johannes Stephan
One-off Publications,
No. 3,
2004
Abstract
The project assesses the roles played by determinants of productivity gaps between Accession Countries in Central East Europe and the more advanced countries in Western Europe. The focus is on the respective weights of determinants and their influence on the potentials for future productivity catch-up.
The convenient feature about assessing productivity levels is that they inform us about the narrowing or divergence of income gaps, provide an indication of international competitiveness, and the sustainability of growth paths (technological development).

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.
