Bankhistorisches Archiv,
No. 2,
2011
Abstract
The present paper gives an overview of the development of Corporate Governance of German banks since the 1950s. The focus will be on economic analysis. The most striking changes in Corporate Governance occurred with the ownership structure of commercial banks, in particular with the major joint-stock banks. In addition to that, the capital market has become a core element of Corporate Governance in all major German banks, which have replaced their prior concentration on the interests of a broadly defined circle of stakeholders by a one-sided concentration on shareholders’ interests. In contrast, with savings banks and cooperative cooperative banks, Corporate Governance has remained unchanged for the most part. Exceptions to this are the regional state banks: in their case, after they had turned away from traditional business models and in particular following the discontinuation of the guarantee obligation, the problems of their Corporate Governance, which were already discernible beforehand, became quite obvious. If you include the financial crisis, beginning in 2007, in the analysis, it becomes evident that it was precisely a Corporate Governance unilaterally geared to shareholders’ interest and the efficiency of the capital market that materially contributed to the evolution and widening of the crisis.

Shocks at Large Banks and Banking Sector Distress: The Banking Granular Residual
S. Blank, Claudia M. Buch, Katja Neugebauer
Journal of Financial Stability,
No. 4,
2009
Abstract
Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix and construct a measure of idiosyncratic shocks at large banks, the so-called Banking Granular Residual. This measure documents the importance of size effects for the German banking system. In a second step, we incorporate this measure of idiosyncratic shocks at large banks into an integrated stress-testing model for the German banking system following De Graeve et al. (2008). We find that positive shocks at large banks reduce the probability of distress of small banks.

Margins of international banking: Is there a productivity pecking order in banking, too?
Claudia M. Buch
Bundesbank Discussion Paper 12/2009,
2009
Abstract
Modern trade theory emphasizes firm-level productivity differentials to explain
the cross-border activities of non-financial firms. This study tests whether a
productivity pecking order also determines international banking activities. Using
a novel dataset that contains all German banks’ international activities, we
estimate the ordered probability of a presence abroad (extensive margin) and the
volume of international assets (intensive margin). Methodologically, we enrich the
conventional Heckman selection model to account for the self-selection of banks
into different modes of foreign activities using an ordered probit. Four main
findings emerge. First, similar to results for non-financial firms, a productivity
pecking order drives bank internationalization. Second, only a few non-financial
firms engage in international trade, but many banks hold international assets, and
only a few large banks engage in foreign direct investment. Third, in addition to
productivity, risk factors matter for international banking. Fourth, gravity-type
variables have an important impact on international banking activities.

The Identification of Technology Regimes in Banking: Implications for the Market Power-Fragility Nexus
Michael Koetter, Tigran Poghosyan
Journal of Banking and Finance,
No. 8,
2009
Abstract
Neglecting the existence of different technologies in banking can contaminate efficiency, market power, and other performance measures. By simultaneously estimating (i) technology regimes conditional on exogenous factors, (ii) efficiency conditional on risk management, and (iii) Lerner indices of German banks, we identify three distinct technology regimes: Public & Retail, Small & Specialized, and Universal & Relationship. System estimation at the regional level reveals that greater bank market power increases bank profitability but also fosters corporate defaults. Corporate defaults, in turn, lead to higher probabilities of bank distress, which supports the market power-fragility hypothesis.

Stages of the 2007/2008 Global Financial Crisis: Is there a Wandering Asset Price Bubble?
Lucjan T. Orlowski
Economics E-Journal 43. Munich Personal RePEc Archive 2008,
2009
Abstract
This study identifies five distinctive stages of the current global financial crisis: the meltdown of the subprime mortgage market; spillovers into broader credit market; the liquidity crisis epitomized by the fallout of Northern Rock, Bear Stearns and Lehman Brothers with counterparty risk effects on other financial institutions; the commodity price bubble, and the ultimate demise of investment banking in the U.S. The study argues that the severity of the crisis is influenced strongly by changeable allocations of global savings coupled with excessive credit creation, which lead to over-pricing of varied types of assets. The study calls such process a “wandering asset-price bubble“. Unstable allocations elevate market, credit, and liquidity risks. Monetary policy responses aimed at stabilizing financial markets are proposed.

Contestability, Technology and Banking
S. Corvoisier, Reint E. Gropp
ZEW Discussion Papers, No. 09-007,
No. 7,
2009
Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.

Monetary Policy and Financial (In)stability: An Integrated Micro–Macro Approach
Ferre De Graeve, Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 3,
2008
Abstract
Evidence on central banks’ twin objective, monetary and financial stability, is scarce. We suggest an integrated micro–macro approach with two core virtues. First, we measure financial stability directly at the bank level as the probability of distress. Second, we integrate a microeconomic hazard model for bank distress and a standard macroeconomic model. The advantage of this approach is to incorporate micro information, to allow for non-linearities and to permit general feedback effects between financial distress and the real economy. We base the analysis on German bank and macro data between 1995 and 2004. Our results confirm the existence of a trade-off between monetary and financial stability. An unexpected tightening of monetary policy increases the probability of distress. This effect disappears when neglecting microeffects and non-linearities, underlining their importance. Distress responses are largest for small cooperative banks, weak distress events, and at times when capitalization is low. An important policy implication is that the separation of financial supervision and monetary policy requires close collaboration among members in the European System of Central Banks and national bank supervisors.

Parenting Benefit – A New Risk for Companies
Nicole Nulsch, Henry Dannenberg
Wirtschaft im Wandel,
No. 7,
2008
Abstract
Mit dem zum 1. Januar 2007 neu eingeführten Elterngeld verfolgt der Gesetzgeber unter anderem das Ziel, mehr Väter für eine Elternzeit zu begeistern. Bislang wurden die Auswirkungen des Elterngelds insbesondere aus familienpolitischer Perspektive betrachtet. Ziel dieses Beitrags ist es jedoch, die unternehmenspolitischen Folgen des Elterngelds zu untersuchen.
Die Entwicklung der Elterngeldanträge im Jahr 2007 deutet darauf hin, dass zunehmend mehr Väter von der Elternzeit Gebrauch machen. Dabei handelt es sich in mehr als der Hälfte der Fälle um berufstätige Väter. Konnten Unternehmen in der Vergangenheit das Risiko, dass eine wichtige Position im Unternehmen für einen längeren Zeitraum aufgrund der Geburt eines Kindes unbesetzt ist, verhältnismäßig einfach dadurch senken, indem ein Mann beschäftigt wurde, wird diese Strategie in Zukunft an Bedeutung verlieren. Es ist zu erwarten, dass dieses veränderte Risikoumfeld einerseits die Karrierechancen der Frauen verbessern und zu einer Verringerung der Lohnlücke zwischen den Geschlechtern beitragen kann. Es ist jedoch auch zu erwarten, dass sich die Risikosituation der Unternehmen insgesamt verschlechtert und bei gegebener Risikotragfähigkeit bisher tragbare Risiken zukünftig nicht mehr eingegangen werden können, was sich negativ auf die wirtschaftliche Entwicklung auswirken könnte.

An Assessment of Bank Merger Success in Germany
Michael Koetter
German Economic Review,
No. 2,
2008
Abstract
German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
No. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.
