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.

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.

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.

Cross-border bank mergers: What lures the rare animal?
Claudia M. Buch, G. DeLong
Journal of Banking and Finance,
No. 9,
2004
Abstract
Although domestic mergers and acquisitions (M&As) in the financial services industry have increased steadily over the past two decades, international M&As were until recently relatively rare. Moreover, the share of cross-border mergers in the banking industry is low compared with other industries. This paper uses a novel dataset of over 3000 mergers that took place between 1985 and 2001 to analyze the determinants of international bank mergers. We test the extent to which information costs and regulations hold back merger activity. Our results suggest that information costs significantly impede cross-border bank mergers. Regulations also influence cross-border bank merger activity. Hence, policy makers can create environments that encourage cross-border activity, but information cost barriers must be overcome even in (legally) integrated markets.

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.

Liberalization of Electricity Markets in Selected European Countries
Albrecht Kauffmann, M. Keim, P. J. J. Welfens
Diskussionsbeiträge des Europäischen Instituts für Internationale Wirtschaftsbeziehungen (EIIW), Bergische Universität Wuppertal, Nr. 124,
No. 124,
2004
Abstract
We look into liberalization issues in the context of the EU Electricity Liberalization. Taking a look at principal issues reveals that the Community Directive 96/92/EC does not really take into account the interdependencies of energy markets. Moreover, third party access is not effectively enforced, particularly not in Germany, where mergers between a major electricity company and the dominant gas company have raised particular issues. Electricity liberalization in Scandinavia is working relatively well. EU accession countries are considered potential electricity exporters in the long run as full restructuring will drive down both energy intensities and electricity intensities. Russia would be wise to quickly become a member country of WTO, not in the least to gain access to Western Europe’s electricity market; the role of Russia so far has been neglected in the discussion of electricity liberalization. Excess capacities in EU-27 can be expected in the medium term. There is considerable doubt that politicians – often with ambitious goals in the field of environmental policy – will allow for a pan-European liberalization of electricity. We also take a closer look at regulatory policy issues.

Information or Regulation: What Drives the International Activities of Commercial Banks?
Claudia M. Buch
Journal of Money Credit,
No. 6,
2003
Abstract
Information costs and regulatory barriers distinguish international financial markets from national ones. Using panel data on bilateral assets and liabilities of commercial banks, I empirically determine the impact of information, costs and regulations, and I isolate intra-EU financial linkages. I confirm that information costs and regulations are important factors influencing international asset choices of banks, but their relative importance differs among countries.

Enterprise-related services in East-Germany – an investigation of the service sector statistics
Siegfried Beer
Wirtschaft im Wandel,
No. 12,
2003
Abstract
According to the national accounts in East Germany, the enterprise-related services have developed substantielly since 1990. This is expressed by the average annual increase of real gross value added of 9.5% (GDP: 4.9%) until 2000. According to the newly introduced service sector statistics (for 2000), firms in the East German enterprise related services have on average 9 employes, and thus, they are only slightly smaller than enterprises in West-Germany. Much bigger differences appear with respect to the average sales and productivity (60% or 45%). Various explanations exist. One major reason obviously is, that enterprises in East-Germany make smaller sales because of the clearly smaller size of enterprises which demand these services. Furthermore the smaller earning power of services demanding enterprises, differences in the branch structur of enterprise related services, and administrative regulations for prices play a role.
