Bank Lending, Bank Capital Regulation and Efficiency of Corporate Foreign Investment
Diemo Dietrich, Achim Hauck
IWH Discussion Papers,
No. 4,
2007
Abstract
In this paper we study interdependencies between corporate foreign investment and the capital structure of banks. By committing to invest predominantly at home, firms can reduce the credit default risk of their lending banks. Therefore, banks can refinance loans to a larger extent through deposits thereby reducing firms’ effective financing costs. Firms thus have an incentive to allocate resources inefficiently as they then save on financing costs. We argue that imposing minimum capital adequacy for banks can eliminate this incentive by putting a lower bound on financing costs. However, the Basel II framework is shown to miss this potential.

Banks’ Internationalization Strategies: The Role of Bank Capital Regulation
Diemo Dietrich, Uwe Vollmer
IWH Discussion Papers,
No. 18,
2006
Abstract
This paper studies how capital requirements influence a bank’s mode of entry into foreign financial markets. We develop a model of an internationally operating bank that creates and allocates liquidity across countries and argue that the advantage of multinational banking over offering cross-border financial services depends on the benefit and the cost of intimacy with local markets. The benefit is that it allows to create more liquidity. The cost is that it causes inefficiencies in internal capital markets, on which a multinational bank relies to allocate liquidity across countries. Capital requirements affect this trade-off by influencing the degree of inefficiency in internal capital markets.

Network investment and the threat of regulation: avoiding monopoly or infrastructure extension
Christian Growitsch, Niels Krap
Wirtschaft im Wandel,
No. 5,
2006
Abstract
Im Sommer 2005 gab die Deutsche Telekom ihre Pläne für den Aufbau eines neuen Glasfasernetzes bekannt. Sie formulierte gleichzeitig die Bedingung, daß dieses Netz weder preislich noch hinsichtlich der Nutzung durch andere Anbieter (Netzzugang) reguliert werden sollte. Um die Investitionen zu ermöglichen, einigte sich die große Koalition im Koalitionsvertrag darauf, das neue Netz von der ex-ante Regulierung auszunehmen und diese Regulierungsfreiheit im Telekommunikationsgesetz zu integrieren. Es stellt sich nun die Frage, wie die Investitionen ermöglicht und gleichzeitig Wohlfahrtsverluste durch Monopolgewinne verhindert werden können. Spieltheoretisch läßt sich zeigen, daß eine Regulierungsbehörde wie die für den deutschen Telekommunikationssektor zuständige Bundesnetzagentur mit steigender Unsicherheit über die erwarteten Kosten und Erträge einer Investition eine zunehmende Toleranz gegenüber Abweichungen von einem von ihr selbst ermittelten und festgelegten Regulierungspreis signalisieren sollte. Dann führt bereits allein Androhung eines regulatorischen Eingriffs zu tolerierbaren Preisen, ohne daß eine tatsächliche Preisregulierung vorgenommen werden muß. Zukünftig sollte die Bundesnetzagentur allerdings Informationsasymmetrien reduzieren und das optimale Niveau an Toleranz vermindern, um zu einem präziseren Interventionspreis und einer effektiveren Regulierungsandrohung zu kommen. Die Wirksamkeit einer solchen Regulierungsandrohung läßt allerdings deutlich nach, wenn der Gesetzgeber den Regulierer per Gesetz von der Nutzung dieses Instrumentes ausschließt. Vor diesem Hintergrund geht der jüngst verfaßte Beschluß der Bundesregierung vom 17. Mai 2006 zur Novelle des Telekommunikationsgesetzes ökonomisch in die richtige Richtung, wird aber in der tatsächlichen Rechtspraxis seine Anreizkompatibilität beweisen müssen.

Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
IWH Discussion Papers,
No. 7,
2006
Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

Essays on Network Regulation – Theoretical and Empirical Evidence from the Electricity Supply Industry
Christian Growitsch
Schriften des IWH,
No. 21,
2005
Abstract
Mit dem Etablieren des gemeinsamen Europäischen Binnenmarktes im Laufe der 80er und 90er Jahre des vergangenen Jahrhunderts und dem damit verbundenen Wegfall von Handelsbarrieren und anderen Wettbewerbshemmnissen rückte die Liberalisierung sogenannter Netzindustrien in den Fokus der Europäischen Politik. Die Deregulierung solcher Sektoren mit physischer Netzinfrastruktur, insbesondere der Märkte für Strom, Gas, Telekommunikation und Schienenverkehr wurde zu einem wesentlichen Aspekt des Ziels der Förderung von Wettbewerb in der Europäischen Ökonomie. Die Einführung wettbewerblicher Strukturen in die ehemalig monopolistischen Netzindustrien bedingte die Notwendigkeit wettbewerbspolitischer Reformen auf nationaler und Europäischer Ebene. Insbesondere die Sicherstellung gleicher Wettbewerbsbedingungen und der Schutz der Verbraucher vor Marktmachtmißbrauch durch die etablierten Anbieter rückte in den Fokus der Wirtschaftspolitik und führte zum Aufbau sektorspezifischer Regulierungsregime. Diese unterscheiden sich deutlich sowohl sektoral wie im Hinblick auf nationale Ordnungsrahmen hinsichtlich ihrer Rahmenbedingungen, ihrer Methoden, ihrer Struktur und ihrer ökonomischen Wirkung. Der Austausch und die Übertragung von Erkenntnissen und Erfahrungen und die kontinuierliche Verbesserung bestehender institutioneller Arrangements sollte daher ein bedeutender Aspekt ökonomischer Forschung und staatlicher Wirtschaftspolitik sein. Die hier vorliegende Sammlung energieökonomischer Aufsätze zielt auf eben jenen Erkenntnistransfer ab. Dazu wird in den ersten beiden Artikeln ein spezifisches Regulierungsregime, der sogenannte verhandelte Netzzugang, und die damit verbundenen Erfahrungen aus dem deutschen Elektrizitätsmarkt vorgestellt. Ein dritter Aufsatz beschäftigt sich mit der Versorgungsqualität in Netzsektoren am Beispiel lokaler Stromverteilnetzbetreiber in einem europäischen Vergleich.

Non-market Allocation in Transport: A Reassessment of its Justification and the Challenge of Institutional Transition
Ulrich Blum
50 Years of Transport Research: Experiences Gained and Major Challenges Ahead,
2005
Abstract
Economic theory knows two systems of coordination: through public choice or through the market principle. If the market is chosen, then it may either be regulated, or it may be fully competitive (or be in between these two extremes). This paper first inquires into the reasons for regulation, it analyses the reasons for the important role of government in the transportation sector, especially in the procurement of infrastructure. Historical reasons are seen as important reasons for bureaucratic objections to deregulation. Fundamental economic concepts are forwarded that suggest market failure and justify a regulatory environment. The reasons for regulation cited above, however, may be challenged; we forward theoretical concepts from industrial organization theory and from institutional economics which suggest that competition is even possible on the level of infrastructure. The transition from a strongly regulated to a competitive environment poses problems that have given lieu to numerous failures in privatization and deregulation. Structural inertia plays an important role, and the incentive-compatible management of infrastructure is seen as the key element of any liberal transportation policy. It requires that the setting of rules on the meta level satisfies both local and global efficiency ends. We conclude that, in market economies, competition and regulation should not be substitutes but complements. General rules, an "ethic of competition" have to be set that guarantee a level playing field to agents; it is complimented by institutions that provide arbitration in case of misconduct.

Quality of Service, Efficiency, and Scale in Network Industries: An Analysis of European Electricity Distribution
Christian Growitsch, Tooraj Jamasb, Michael Pollitt
IWH Discussion Papers,
No. 3,
2005
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.
