Abstract
The aim of this study is to assess the contributions of investment banking to the economy with a particular focus on the German economy. To this end we analyse both the economic benefits and the costs stemming from investment banking.
The study focuses on investment banks as this part of banking is particularly relevant for financing companies as well as the development and use of specific products to support the needs of private and professional clients. The assessment of benefits and costs of investment banking has been conducted from a European perspective. Nevertheless there is a focus on the German economy to allow a more detailed analysis of certain aspects as for example the use of derivatives by German companies, the success of M&As in Germany or the effect of securitization on loan supply and GDP in Germany. For comparison purposes other European countries and also the U.S. have been taken into account.
The last financial crisis has shown the negative impacts of banks on the financial system and the whole economy. In a study on the contribution of investment banks to systemic risk we quantify the negative side of the investment banking business.
In the last part of the study we assess how the effects of regulatory changes on investment banking. All important changes in banking and capital market regulation are taken into account such as Basel III, additional capital requirements for systemically important financial institutions, regulation of OTC derivatives and specific taxes.

Informed and Uninformed Investment in Housing: The Downside of Diversification
Elena Loutskina, Philip E. Strahan
Review of Financial Studies,
No. 5,
2011
Abstract
Mortgage lenders that concentrate in a few markets invest more in information collection than diversified lenders. Concentrated lenders focus on the information-intensive jumbo market and on high-risk borrowers. They are better positioned to price risks and, thus, ration credit less. Adverse selection, however, leads to higher retention of mortgages relative to diversified lenders. Finally, concentrated lenders have higher profits than diversified lenders, their profits vary less systematically, and their stock prices fell less during the 2007—2008 credit crisis. The results imply that geographic diversification led to a decline in screening by lenders, which likely played a role in the 2007–2008 crisis.

The Determinants of Bank Capital Structure
Reint E. Gropp, Florian Heider
Review of Finance,
No. 4,
2010
Abstract
The paper shows that mispriced deposit insurance and capital regulation were of second-order importance in determining the capital structure of large U.S. and European banks during 1991 to 2004. Instead, standard cross-sectional determinants of non-financial firms’ leverage carry over to banks, except for banks whose capital ratio is close to the regulatory minimum. Consistent with a reduced role of deposit insurance, we document a shift in banks’ liability structure away from deposits towards non-deposit liabilities. We find that unobserved time-invariant bank fixed-effects are ultimately the most important determinant of banks’ capital structures and that banks’ leverage converges to bank specific, time-invariant targets.

Cross-border Diversification in Bank Asset Portfolios
Claudia M. Buch, J.C. Driscoll, C. Ostergaard
International Finance,
forthcoming
Abstract
We compute optimally diversified international asset portfolios for banks located in France, Germany, Italy, the United Kingdom and the United States using the mean–variance portfolio model with currency hedging. We compare these benchmark portfolios with the actual cross-border asset positions of banks from 1995 to 2003 and ask whether the differences are best explained by regulations, institutions, cultural conditions or other financial frictions. Our results suggest that both culture and regulations affect the probability of a country's being overweighted in banks' portfolios: countries whose residents score higher on a survey measure of trust are more likely to be overweighted, while countries that have tighter capital controls are less likely to be overweighted. From a policy standpoint, the importance of culture suggests a limit to the degree of financial integration that may be achievable by the removal of formal economic barriers.

Bank Regulation and Supervision in Bank-dominated Financial Systems: A Comparison between Japan and Germany
Diemo Dietrich, Ralf Bebenroth, Uwe Vollmer
European Journal of Law and Economics,
2009
Abstract
Diese Arbeit vergleicht die Bankenregulierung und -aufsicht in Japan und Deutschland. Diese Länder werden betrachtet, weil sie beide ein bankendominiertes Finanzsystem aufweisen und trotzdem Unterschiede in Bezug auf die Bankenstabilität aufweisen. Es wird gezeigt, dass Japan und Deutschland unterschiedliche Ansätze zur Regulierung und Aufsicht von Banken gewählt haben, und fragt, warum sie ihre Wahl so getroffen haben. Es wird argumentiert, dass Regulierung und Aufsicht in Japan weniger effizient gewesen sind und dass diese Unterschiede maßgeblich für das verschiedene Bankenverhalten war.

Banking Integration, Bank Stability, and Regulation: Introduction to a Special Issue of the International Journal of Central Banking
Reint E. Gropp, H. Shin
International Journal of Central Banking,
No. 1,
2009
Abstract
The link between banking integration and financial stability has taken center stage in the wake of the current financial crisis. To what extent is the banking system in Europe integrated? What role has the introduction of the common currency played in this context? Are integrated banking markets more vulnerable to contagion and financial instability? Does the fragmented regulatory framework in Europe pose special problems in resolving bank failures? What policy reforms may become necessary? These questions are of considerable policy interest as evidenced by the extensive discussions surrounding the design and implementation of a new regulatory regime and by the increasing attention coming from academia.

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.

Do Weak Supervisory Systems Encourage Bank Risk-taking?
Claudia M. Buch, G. DeLong
Journal of Financial Stability,
2008
Abstract
Weak bank supervision could give banks the ability to shift risk from themselves to supervisors. We use cross-border bank mergers as a natural experiment to test changes in risk and the impact of supervision. We examine cross-border bank mergers and find that the supervisory structures of the partners’ countries influence changes in post-merger total risk. An acquirer from a country with strong supervision lowers total risk after a cross-border merger. However, total risk increases when the target bank is located in a country with relatively strong supervision. This result is consistent with strong host regulators limiting the risky activities of their local banks. Foreign-owned competitors could then engage in the risky projects, especially if the foreign banks’ supervisors are not strong. An acquirer entering a country with strong supervision appears to shift risk back to its home country. The results suggest that bank supervisors can reduce total banking risk in their countries by being strong.

International Banking and the Allocation of Risk
Claudia M. Buch
IAW Discussion Paper No. 32,
2007
Abstract
Macroeconomic risks could magnify individual bank risk. Mitigating the influence of economy-wide risks on banks could therefore be very important to maintain a smooth-running banking system. In this paper, we explore the extent to which macroeconomic risks affect banks. We use a bank-level dataset on over 2,000 banks worldwide for the years 1995-2002 to study the effect of macroeconomic volatility, the openness of the banking system, and banking regulations on bank risks. Our measure of bank risk is the volatility of banks' pre-tax profits. We find that macroeconomic volatility increases banks' profit volatility and that international openness of the banking system lowers bank risk. We find no impact of banking regulation on profit volatility. Our findings suggest that if policymakers want to lower bank risk, they should seek to lower macroeconomic volatility as well as increase openness in the banking system.

The Role of Credit Ratings in Banking Regulations. Credit Ratings Are Insufficiently Anticipating the Risk for Currency Crises.
Tobias Knedlik, Johannes Ströbel
Wirtschaft im Wandel,
No. 10,
2007
Abstract
Bonitätsbewertungen durch Rating-Agenturen gewinnen durch die unter dem Stichwort Basel II diskutierten Reformvorschläge zur Bankenregulierung an Bedeutung. Insbesondere hängt das durch die Regulierung geforderte Mindesteigenkapital unter dem standardisierten Ansatz von Basel II von der Bewertung der Kreditrisiken durch externe Rating-Agenturen ab. Bonitätsbewertungen, speziell von souveränen Schuldnern, bestimmen damit wesentlich die Höhe des Mindesteigenkapitals von Banken. In der Vergangenheit haben Rating-Agenturen Währungskrisenrisiken systematisch unterschätzt. Diese sind jedoch für die Bewertung des Kreditausfallrisikos souveräner Schuldner wichtig. Die prozyklischen Effekte von Basel II entstehen vor allem dadurch, daß im Fall von Währungskrisen aufgrund der zu positiven Bewertung im Vorfeld der Krise schlagartig massive Herabstufungen notwendig werden. Diese Effekte können nur minimiert werden, wenn die währungskriseninduzierten Kreditausfallrisiken angemessen berücksichtigt werden. Die Kritik an der Methode der Rating-Agenturen, insbesondere an mangelnder Berücksichtigung neuerer Währungskrisenmodelle infolge der Asienkrisen von 1997/98, führte zu Reaktionen der Agenturen. So sagte z. B. Standard and Poor’s die Berücksichtigung mikroökonomischer Indikatoren zu, die bei aktuellen Krisen als Krisenfaktoren erkannt wurden. In der vorliegenden Arbeit wird anhand eines Beispiels untersucht, inwiefern sich empirische Anzeichen dafür erkennen lassen, daß mikroökonomische Indikatoren in der Praxis der Bonitätsprüfung beachtet werden. Das Ergebnis der empirischen Untersuchungen zeigt, daß traditionelle makroökonomische Indikatoren die Rating-Ergebnisse dominieren. In aktuellen Ratings können keine Anzeichen für eine stärkere Berücksichtigung von Mikro-Indikatoren gefunden werden. Es muß daher geschlußfolgert werden, daß, wie in der Wirtschaft im Wandel 8/2007 ausgeführt, auch weiterhin prozyklische, krisenverstärkende Effekte von Basel II ausgehen. Die Rating-Agenturen erfüllen bislang die Rolle als frühzeitige Antizipatoren für Währungskrisenrisiken unzureichend.
