The influence of Vertical Integration and Property Rights on Network Access Charges in the German Electricity Markets

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.

Employment effects of development of renewable energies

No. 1,
2004
Abstract
Die Bundesregierung strebt bis zum Jahr 2010 eine Verdopplung des Anteils erneuerbarer Energien am Primärenergie- sowie am Bruttostromverbrauch an. Das vorrangige Ziel der damit verbundenen Umstrukturierung des Energiesektors ist die Verbesserung der Umweltqualität. Es darf jedoch nicht außer Acht gelassen werden, dass die Förderung erneuerbarer Energien zwangsläufig auch gesamtwirtschaftliche Auswirkungen hat. Angesichts der anhaltend angespannten Lage am Arbeitsmarkt stehen dabei insbesondere die Beschäftigungseffekte der Förderung erneuerbarer Energien im Mittelpunkt des öffentlichen und wirtschaftspolitischen Interesses. Vor diesem Hintergrund hat das Institut für Wirtschaftsforschung Halle im Auftrag des Bundesministeriums für Wirtschaft und Arbeit (BMWA) die gesamtwirtschaftlichen und insbesondere beschäftigungsrelevanten Auswirkungen des angestrebten Ausbaus erneuerbarer Energien untersucht. Im Gegensatz zu anderen Studien dieser Art wurde dabei besonderer Wert auf eine dynamische Analyse gelegt, die neben den expansiven Beschäftigungsimpulsen im Bereich der erneuerbaren Energien auch die gegenläufigen Beschäftigungswirkungen berücksichtigt, die durch Verdrängung konventioneller Energieträger und durch erhöhte Steuern zur Finanzierung von Subventionen für regenerative Energien entstehen. Die vorliegende Untersuchung gibt eine zusammenfassende Darstellung der Vorgehensweise und der Ergebnisse des Forschungsprojekts. Es zeigt sich, dass per saldo durch den verstärkten Ausbau erneuerbarer Energien keine zusätzliche Beschäftigung generiert wird.

The Reform of Local Public Services of General Interest in Europe
Peter Haug, Martin T. W. Rosenfeld
Applied Economics Quarterly (Supplement),
2004
Abstract
The benefits of a reduced supply of local public services may more than outweigh the supposed welfare losses. This was suggested by various theoretical and empirical investigations in many fields of economics during the last decades. Nevertheless, local and national politicians, trade unionists, charities, and other lobbyists have succeeded in preventing further liberalisation of “services of general interest” in Europe. This article examines why these preserve agents have been and are still successful. The analysis is based on an institutional economic approach. Several policy measures and institutional changes are suggested to either reduce influence of preserve agents or to compensate them for their losses.

Diversifikation und regionale Wirtschafts- und Beschäftigungsentwicklung - Eine empirische Analyse für ausgewählte deutsche Gebiete
Peter Haug
Jahrbuch für Regionalwissenschaft,
No. 2,
2004
Abstract
This article analyses the effects of heterogeneous economic structures on the long-term development of regional employment. A simple model is introduced to illustrate the beneficial outcomes for households as well as for enterprises of locating in highly diversified municipalities because risk (volatility of income, recruitment costs in a broader sense) diminishes for both. Econometric results for a sample of municipalities in Lower Saxony provide some evidence for a positive effect of local economic diversification on employment opportunities. The results seem to be not confined to the aggregated local labour demand but also apply to most branches the local business sector.

Evolving Structural Patterns in the Enlarging European Division of Labour: Sectoral and Branch Specialisation and the Potentials for Closing the Productivity Gap
Johannes Stephan
IWH-Sonderhefte,
No. 5,
2003
Abstract
This report summarises the results generated in empirical analysis within a larger EU 5th FP RTD-project on the determinants of productivity gaps between the current EU-15 and accession states in Central East Europe. The focus of research in this part of the project is on sectoral specialisation patterns emerging as a result of intensifying integration between the current EU and a selection of six newly acceding economies, namely Estonia, Poland, the Czech and Slovak Republics, Hungary and Slovenia. The research-leading question is concerned with the role played by the respective specialisation patterns for (i) the explanation of observed productivity gaps and for (ii) the projection of future potentials of productivity growth in Central East Europe.
For the aggregated level, analysis determines the share of national productivity gaps accountable to acceding countries’ particular sectoral patterns, and their role for aggregate productivity growth: in Poland, the Slovak Republic and Hungary, sectoral shares of national productivity gaps are considerable and might evolve into a ‘barrier’ to productivity catch-up.Moreover, past productivity growth was dominated by a downward adjustment in employment rather than structural change. With the industrial sector of manufacturing having been identified as the main source of national productivity gaps and growth, the subsequent analysis focuses on the role of industrial specialisation patterns and develops an empirical model to project future productivity growth potentials. Each chapter closes with some policy conclusions.

Why do we have an interbank money market?
Jürgen Wiemers, Ulrike Neyer
IWH Discussion Papers,
No. 182,
2003
Abstract
The interbank money market plays a key role in the execution of monetary policy. Hence, it is important to know the functioning of this market and the determinants of the interbank money market rate. In this paper, we develop an interbank money market model with a heterogeneous banking sector. We show that besides for balancing daily liquidity fluctuations banks participate in the interbank market because they have different marginal costs of obtaining funds from the central bank. In the euro area, which we refer to, these cost differences occur because banks have different marginal cost of collateral which they need to hold to obtain funds from the central bank. Banks with relatively low marginal costs act as intermediaries between the central bank and banks with relatively high marginal costs. The necessary positive spread between the interbank market rate and the central bank rate is determined by transaction costs and credit risk in the interbank market, total liquidity needs of the banking sector, costs of obtaining funds from the central bank, and the distribution of the latter across banks.

The State of the World Economy and the German Economy in Fall of 2003 - Report of the six economic research institutes
Wirtschaft im Wandel,
No. 14,
2003
Abstract
Growth of total world output has accelerated since last spring. The factors that had dampened growth during the early months of 2003 have lapsed, economic policy continues to be stimulating and the assessment of the prospects has become more favourable. The recovery is led once again by the United States. Developments in Japan are surprisingly good and the phase of weakness in Southeast Asia has been overcome. Whereas output in the EU accession countries has continued to grow strongly, the euro area has remained mired in stagnation....

Opportunities and Risks for Regional Development in Former East German Brown Coal Mining Areas: The Case of the “Geiseltal” Mining Area in Saxony-Anhalt
Peter Franz
Wirtschaft im Wandel,
No. 11,
2003
Abstract
The rehabilitation of former brown coal open mining locations represents an important section of the economic and ecological restructuring process in East Germany, taking place since 1990. The recent progress in rehabilitation has led to large amounts of newly disposable space and thus expands the opportunities for regional development, especially with respect to tourism. But the possible positive effects are at risk because of diverse obstacles. In the case of the former open mining location of the “Geiseltal” in the south of Saxony-Anhalt such obstacles show up in form of a strong identification of the residents with the tradition of mining industry, in form of the expansive interests of nature protection organizations, and in form of inadequate organisational structures of the local public administration. In the case of a tourism-oriented development strategy risks arise concerning the actual duration of the remaining recultivation process and concerning the competition with locations with similar development targets.
