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.

The Impact of Technology and Regulation on the Geographical Scope of Banking
Hans Degryse, Steven Ongena
Oxford Review of Economic Policy,
No. 4,
2004
Abstract
We review how technological advances and changes in regulation may shape the (future) geographical scope of banking. We first review how both physical distance and the presence of borders currently affect bank lending conditions (loan pricing and credit availability) and market presence (branching and servicing). Next we discuss how technology and regulation have altered this impact and analyse the current state of the European banking sector. We discuss both theoretical contributions and empirical work and highlight open questions along the way. We draw three main lessons from the current theoretical and empirical literature: (i) bank lending to small businesses in Europe may be characterized both by (local) spatial pricing and resilient (regional and/or national) market segmentation; (ii) because of informational asymmetries in the retail market, bank mergers and acquisitions seem the optimal route of entering another market, long before cross-border servicing or direct entry are economically feasible; and (iii) current technological and regulatory developments may, to a large extent, remain impotent in further dismantling the various residual but mutually reinforcing frictions in the retail banking markets in Europe. We conclude the paper by offering pertinent policy recommendations based on these three lessons.

Flexible utilization of labor strengthens industrial enterprises´ ability to adapt to fluctuations in business - an empirical east-west comparison based on the IAB company panel
Brigitte Loose, Udo Ludwig
Wirtschaft im Wandel,
No. 12,
2004
Abstract
Based on an individual data set, this article investigates the question of which conventional methods and new instruments companies use to adapt to fluctuations in business and what distinguishes these companies from other ones which have not implemented such instruments. In particular, the role of the technical equipment as well as the personnel policy and tariff policy are analyzed. An empirical comparison between the East and West German manufacturing industries demonstrates whether East German firms have competitive advantages. While the technological conditions for firms´ flexibility are somewhat less pronounced in East German, the proportion of “standardized“ and flexible employment is nearly the same in the East-West comparison. Differences exist among small, middle-sized and large firms as well as among types of yield. The weak orientation with respect to agreed wages and hours worked as well as the mainly gratuitous reduction of unpaid overtime which can be implemented over the whole year, prove to be an advantage. The investigation is based on a data set from the IAB company panel of manufacturing industries in 2003.

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.

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.

Opportunities and Risks for Regional Development in Former East German Brown Coal Mining Areas: The Case of the “Geiseltal” Mining Area in Saxony-Anhalt

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.

Local conditions for the New Economy in structurally weak areas: The Example of Saxony-Anhalt
Walter Komar
Wirtschaft im Wandel,
No. 9,
2003
Abstract
The paper presents the main results of an analysis of the regional conditions for the New Economy in Saxonia-Anhalt, i. e. for the sectors of modern biotechnology and modern information technology. Therefore, the regional conditions in Saxonia-Anhalt and the Raumordungsregion (ROR) Munich are compared. Latter region is one of the most advanced areas in Germany with regard to the two sectors under consideration. As expected, the ROR Munich shows better results in most aspects. Nevertheless, an important result is that even in less economically advanced regions modern biotechnology and modern information technology have chances for a good economic performance. Therfore, these regions must use better their existing potentials and eliminate their still existing regional deficits.

New industries in Eastern Germany - The state of the development of modern biotechnologies in Saxony-Anhalt
Walter Komar
Wirtschaft im Wandel,
No. 16,
2002
Abstract
East German regions are able to increase their economics and innovation potential, if they orient themselves on technologies, which release important growth effects. Such growth branch is the modern biotechnology. In this paper the development and the location factors of the biotechnology industry in Saxonia-Anhalt are analyzed and compared with the bio region Munich, which rank to among the best bio regions in Germany. The analysis shows that the development of the modern biotechnology in East German regions can be favoured, if the location factors are improved.
