Systeme monetärer Steuerung - Analyse und Vergleich geldpolitischer Strategien. Schriften zu Ordnungsfragen der Wirtschaft, Band 86,
No. 86,
2007
Abstract
Geldpolitische Strategien, insbesondere die der EZB, sind in jüngerer Vergangenheit verstärkt in den Fokus der öffentlichen und wissenschaftlichen Debatte gelangt. Nach einer Einführung in konzeptionelle Grundlagen geldpolitischer Strategien vergleicht die vorliegende Arbeit mit Inflationssteuerung und Geldmengensteuerung die beiden vorherrschenden geldpolitischen Stratgien. Kriterien sind hierbei unter anderem die Modellierung des Transmissionsmechanismus, die Rolle von Erwartungen, die Bedeutung nominaler Anker sowie Transparenz und Verantwortlichkeit. Den Abschluß bildet eine kritische Würdigung der aktuellen EZB-Strategie.

Slippery Slopes of Stress: Ordered Failure Events in German Banking
Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 2,
2007
Abstract
Outright bank failures without prior indication of financial instability are very rare. In fact, banks can be regarded as troubled to varying degrees before outright closure. But failure studies usually neglect the ordinal nature of bank distress. We distinguish four different kinds of increasingly severe events on the basis of the distress database of the Deutsche Bundesbank. Only the worst distress event entails a bank to exit the market. Since the four categories of hazard functions are not proportional, we specify a generalized ordered logit model to estimate respective probabilities of distress simultaneously. We find that the likelihood of ordered distress events changes differently in response to given changes in the financial profiles of banks. Consequently, bank failure studies should account more explicitly for the different shades of distress. This allows an assessment of the relative importance of financial profile components for different degrees of bank distress.

Interbank Exposures: An Empirical Examination of Contagion Risk in the Belgian Banking System
Hans Degryse, Grégory Nguyen
International Journal of Central Banking,
No. 2,
2007
Abstract
Robust (cross-border) interbank markets are important for the proper functioning of modern financial systems. However, a network of interbank exposures may lead to domino effects following the event of an initial bank failure. We investigate the evolution and determinants of contagion risk for the Belgian banking system over the period 1993–2002 using detailed information on aggregate interbank exposures of individual banks, large bilateral interbank exposures, and cross-border interbank exposures. The "structure" of the interbank market affects contagion risk. We find that a change from a complete structure (where all banks have symmetric links) toward a "multiplemoney-center" structure (where money centers are symmetrically linked to otherwise disconnected banks) has decreased the risk and impact of contagion. In addition, an increase in the relative importance of cross-border interbank exposures has lowered local contagion risk. However, this reduction may have been compensated by an increase in contagion risk stemming from foreign banks.

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.

Why do banks hold capital in excess of regulatory requirements? A functional approach
Diemo Dietrich, Uwe Vollmer
DBW-Die Betriebswirtschaft,
No. 2,
2007
Abstract
Dieser Beitrag erklärt, warum Banken Eigenkapitalvorschriften übererfüllen. Es wird gezeigt, dass Banken ihre Eigenkapitalquote strategisch bei Nachverhandlungen mit Kreditnehmern nutzen können, da sie ihre Selbstbindungsfähigkeit beeinflusst, ausstehende Kredite einzufordern. Weil dieser Zusammenhang nicht-monoton ist, kann eine Bank gezwungen sein, mehr Eigenkapital als vorgeschrieben zu halten.

FDI versus exports: Evidence from German banks
Claudia M. Buch, A. Lipponer
Journal of Banking and Finance,
No. 3,
2007
Abstract
We use a new bank-level dataset to study the FDI-versus-exports decision for German banks. We extend the literature on multinational firms in two directions. First, we simultaneously study FDI and the export of cross-border financial services. Second, we test recent theories on multinational firms which show the importance of firm heterogeneity [Helpman, E., Melitz, M.J., Yeaple, S.R., 2004. Export versus FDI. American Economic Review 94 (1), 300–316]. Our results show that FDI and cross-border services are complements rather than substitutes. Heterogeneity of banks has a significant impact on the internationalization decision. More profitable and larger banks are more likely to expand internationally than smaller banks. They have more extensive foreign activities, and they are more likely to engage in FDI in addition to cross-border financial services.

Repercusiones de la integración y consolidación de los sectores bancarios europeos sobre la innovación y las actividades de los emprendedores
Hans Degryse, Steven Ongena, Maria Fabiana Penas
Papeles de Economía Española,
No. 110,
2006
Abstract
En este artículo se analiza si el programa de intensificación de la integración del sector financier europeo puede dañar a la innovación y al crecimiento en Europa. En particular, es preciso resaltar los problemas que dicha integración financiera puede ocasionar sobre los últimos avances en materia de desarrollo empresarial. La integración financiera, al intensificar la competencia y la consolidación del sector bancario europeo, podría poner en peligro la financiación procedente de las fuentes más innovadoras. Sin embargo, al sopesar los datos actuales, la conclusión es que estos problemas serían, a lo sumo, transitorios.

The role of banking portfolios in the transmission from the currency crises to banking crises - potential effects of Basel II
Tobias Knedlik, Johannes Ströbel
IWH Discussion Papers,
No. 21,
2006
Abstract
Die vorliegende Arbeit untersucht die möglichen Effekte der Basel II-Bankenregulierung auf die Transmission von Währungskrisen zu Bankenkrisen. Die Analyse des Beispiels Südkorea zeigt die wichtige Rolle der Unausgeglichenheit von Bankaktiva und -passiva in bezug auf deren Fristigkeit und Währung bei diesem Transmissionsprozess und stellt dar wie Basel II auf die Bankenbilanzen gewirkt hätte. Es wird gezeigt, dass die regulatorischen Kapitalanforderungen unter Basel II, aufgrund der guten Kreditratings im Vorfeld der Krise, geringer gewesen wären als unter Basel I. Dadurch wäre die Krise verschärft worden. Im zweiten Teil der Arbeit wird analysiert, ob die Ratingagenturen ihr Verhalten seit dem Versagen bei der Prognose der Asienkrise geändert haben. Dieser Beitrag findet keine empirische Evidenz für eine Berücksichtigung der Unausgeglichenheit in den Bankenbilanzen bei der Ableitung von Ratingergebnissen für Länder. Deshalb muss die Effektivität von Basel II bei der Prävention der Transmission von Währungs- zu Bankenkrisen sowohl im Falle Südkoreas als auch bei möglichen zukünftigen Krisen angezweifelt werden.

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.

Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses
Michael Koetter
Journal of Financial Services Research,
No. 2,
2006
Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.
