Abstract
Quality of service is of major economic significance in natural monopoly infrastructure industries and is increasingly addressed in regulatory schemes. However, this important aspect is generally not reflected in efficiency analysis of these industries. In this paper we present an efficiency analysis of electricity distribution networks using a sample of about 500 electricity distribution utilities from seven European countries. We apply the stochastic frontier analysis (SFA) method on multi-output translog input distance function models to estimate cost and scale efficiency with and without incorporating quality of service. We show that introducing the quality dimension into the analysis affects estimated efficiency significantly. In contrast to previous research, smaller utilities seem to indicate lower technical efficiency when incorporating quality. We also show that incorporating quality of service does not alter scale economy measures. Our results emphasise that quality of service should be an integrated part of efficiency analysis and incentive regulation regimes, as well as in the economic review of market concentration in regulated natural monopolies.

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.

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
Externe Publikationen,
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
Externe Publikationen,
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
Der Beitrag beschäftigt sich mit Fragen der Liberalisierung der Elektrizitätsmärkte in der EU. Man kann feststellen, dass die Gemeinschaftsdirektive 96/92/EC die Wechselbeziehungen der Elektrizitätsmärkte nicht ausreichend behandelt. Außerdem wird vor allem in Deutschland der Zugang für Dritte nicht effektiv gefördert, wobei der Zusammenschluss eines großen Elektrizitätsunternehmens und einem dominanten Gasunternehmen neue spezielle Fragen aufgeworfen hat. Hingegen verläuft der Liberalisierungsprozess in Skandinavien konsequenter. Osteuropäische EU-Beitrittsländer sind langfristig potenzielle Elektrizitätsexporteure sobald Modernisierungen zu niedrigeren Energie- und Elektrizitätsverbrauch führen. Russland sollte rasch WTO-Mitglied werden, um Zugang zu den westeuropäischen Elektrizitätsmärkten zu bekommen, wobei Russland in den gesamten Liberalisierungsdiskussionen noch keine Rolle gespielt hat. Mittelfristig können Überschusskapazitäten in einer EU-27 erwartet werden. Zweifelhaft jedoch ist, ob Politiker, die ansonsten so ehrgeizige Ambitionen in der Umweltpolitik zeigen, einer gesamteuropäischen Liberalisierung der Elektrizitätsmärkte zustimmen werden. Außerdem werden regulierungspolitische Aspekte behandelt.

Information or Regulation: What Drives the International Activities of Commercial Banks?
Claudia M. Buch
Journal of Money Credit,
No. 6,

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.

A revised theory of contestable markets : applied on the German telecommunication sector
Christian Growitsch, Thomas Wein
Externe Publikationen,
No. 275,
2002
Abstract
Despite the scepticism raised by the German Monopoly Commission our analysis shows that the revised theory of contestable markets can be applied to the telecommunications market better than expected. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit is possible without any costs, and the price adjustment lag exceeds 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 are satisfied for potential competition to exist. We applied the ‘revised’ contestable market theory to the German telecommunication market and have been able to clearly identify the value added stages in which regulation is required. Under the present conditions local loops - which can be determined as natural monopolies - are not contestable due to sunk costs, high entry lags expected and a probable short price adjustment lag. Local loops can be identified as monopolistic bottlenecks therefore. Regional and local connection networks should also be regulated because a high entry lag and a low price adjustment lag have to be expected as well as current competition does not exist today. The national connection network shows current competition between several network providers; hence regulation can be abolished in this field. Assumed that network access is regulated, services can be supplied by several competing firms.
