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.

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.

Employment restraints in public service - considering scientific assistants in research establishments
Herbert Buscher
Wirtschaft im Wandel,
No. 6,
2005
Abstract
Spätestens mit den so genannten Hartz-Reformen auf dem Arbeitsmarkt verstärkt sich das Interesse der Öffentlichkeit an der Arbeitsvermittlung und ihrer Wirksamkeit. Eine effiziente Arbeitsvermittlung ist nicht nur wünschenswert, sondern auch notwendige Voraussetzung für einen spürbaren Abbau von Arbeitslosigkeit. Aber die Vermittlung allein ist nur eine notwendige, keine hinreichende Bedingung dafür, dass die Arbeitsuchenden auch entsprechende Beschäftigungsverhältnisse abschließen können. Gesetzliche und tarifvertragliche Regelungen können trotz aller Vermittlungsbemühungen dazu führen, dass potenzielle Arbeitsplätze nicht besetzt werden.

Deposit Insurance, Moral Hazard and Market Monitoring
Reint E. Gropp, Jukka M. Vesala
Review of Finance,
No. 4,
2004
Abstract
The paper analyses the relationship between deposit insurance, debt-holder monitoring, and risk taking. In a stylised banking model we show that deposit insurance may reduce moral hazard, if deposit insurance credibly leaves out non-deposit creditors. Testing the model using EU bank level data yields evidence consistent with the model, suggesting that explicit deposit insurance may serve as a commitment device to limit the safety net and permit monitoring by uninsured subordinated debt holders. We further find that credible limits to the safety net reduce risk taking of smaller banks with low charter values and sizeable subordinated debt shares only. However, we also find that the introduction of explicit deposit insurance tends to increase the share of insured deposits in banks' liabilities.

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.

Does Transparency of Central Banks Produce Multiple Equilibria on Currency Markets?
Axel Lindner
IWH Discussion Papers,
No. 178,
2003
Abstract
A recent strand of literature (see Morris and Shin 2001) shows that multiple equilibria in models of markets for pegged currencies vanish if there is slightly diverse information between traders. It is known that this approach works only if there is not too precise common knowledge in the market. This has led to the conclusion that central banks should try to avoid making their information common knowledge. We present a model in which more transparency of the central bank means better private information, because each trader utilizes public information according to her own private information. Thus, transparency makes multiple equilibria less likely.

Markets for Bank Subordinated Debt and Equity in Basel Committee Member Countries
Reint E. Gropp, Jukka M. Vesala
BCBS Working Papers, No. 12,
No. 12,
2003
Abstract
This Basel Committee working paper is a study of the markets for banks' securities in ten countries (Belgium, France, Germany, Japan, the Netherlands, Spain, Sweden, Switzerland, the United Kingdom, and the United States). It aims at contributing to the assessment of the potential effectiveness of direct and indirect market discipline. This is achieved through collecting a rich set of data on the detailed characteristics of the instruments used by banks to tap capital markets, the frequency and size of their issuance activity, and the share of issuing banks in national banking systems. Further, information is collected on the amounts of debt and equity outstanding and about trading volumes and liquidity. Developments over the period from 1990-2001 are evaluated.
The paper focuses on subordinated bonds among banks' debt instruments, because they are the prime class of uninsured instruments suited to generate market discipline and have been proposed by some observers as a mandatory requirement for banks.

Wage and income subsidies for recipients of public and unemployment assistance
Wolfram Kempe, Hilmar Schneider
Wirtschaft im Wandel,
No. 16,
2001
Abstract
In dieser Arbeit, die auf einem Kapitel eines Gutachtens für das Bundesministerium der Finanzen zu den Anreizwirkungen der Sozialhilfe beruht, werden drei Kombilohnstrategien mit einer engen Zielgruppenbindung hinsichtlich ihrer Effekte bezüglich Erwerbsbereitschaft und fiskalischen Folgen für Ost- und Westdeutschland untersucht. Die Arbeitsangebotsentscheidung wird dabei unter Berücksichtigung des Haushaltskontextes im Rahmen eines mikroökonometrischen Conditional-Logit-Modells erfasst. Die Bereitschaft zur Aufnahme einer Erwerbsarbeit steigt tatsächlich, unterscheidet sich je nach Reformkonzept, Region, Geschlecht und Haushaltskontext aber beträchtlich. Die enge Zielgruppenbeschränkung auf Sozialtransferbezieher hat zur Folge, dass bei Erwerbsaufnahme trotz Subvention ein Teil der Transferzahlungen durch eigenes Einkommen ersetzt wird und die gesamtfiskalische Belastung des Staates damit zurückgeht.

Rating Agency Actions and the Pricing of Debt and Equity of European Banks: What Can we Infer About Private Sector Monitoring of Bank Soundness?
Reint E. Gropp, A. J. Richards
Economic Notes,
No. 3,
2001
Abstract
The recent consultative papers by the Basel Committee on Banking Supervision has raised the possibility of an explicit role for external rating agencies in the assessment of the credit risk of banks’ assets, including interbank claims. Any judgement on the merits of this proposal calls for an assessment of the information contained in credit ratings and its relationship to other publicly available information on the financial health of banks and borrowers. We assess this issue via an event study of rating change announcements by leading international rating agencies, focusing on rating changes for European banks for which data on bond and equity prices are available. We find little evidence of announcement effects on bond prices, which may reflect the lack of liquidity in bond markets in Europe during much of our sample period. For equity prices, we find strong effects of ratings changes, although some of our results may suffer from contamination by contemporaneous news events. We also test for pre-announcement and post-announcement effects, but find little evidence of either. Overall, our results suggest that ratings agencies may perform a useful role in summarizing and obtaining non-public information on banks and that monitoring of banks’ risk through bond holders appears to be relatively limited in Europe. The relatively weak monitoring by bondholders casts some doubt on the effectiveness of a subordinated debt requirement as a supervisory tool in the European context, at least until bond markets are more developed.
