No. 2,

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.

Die Lage der Weltwirtschaft und der deutschen Wirtschaft im Frühjahr 2007
Wirtschaft im Wandel,
1. Sonderausgabe
2007
Abstract
In spring 2007, the global economy remains robust. While growth rates have declined slightly from last year, as business activity in the US has slowed, they continue to reflect an upswing, which by now has held on for a notably long time. Especially the developing and emerging countries have been raising output very fast, due in part to their increasing role in the international division of labour. In the industrialised economies, on the other hand, the current recovery has not been remarkably strong. So far the slowdown in the US economy has not spilled over to other regions and the Euro Area as well as Japan continue to expand at a high pace. Here expansive monetary policy provided a notable support. Buoyant financial markets stimulated the world economy additionally, even though market volatility has increased since the end of February. The US central bank’s current concern with inflationary risks keeps it from loosening its slightly restrictive monetary policy. It will be the second half of the year – when price pressures have eased – until the Fed makes its first rate cut. The ECB, on the other hand, has been preparing financial markets for a further increase in interest rates by summer. In 2007 and 2008 the growth disparities in the industrialised countries will diminish. On one hand, the upswing in the Euro Area will start to moderate, as fiscal policy hampers business activity and monetary policy will not stimulate anymore. On the other hand, the US economy will slowly gain pace from summer onwards; the emerging markets will continue to develop in a highly dynamic fashion. World-GDP in this and next year will likely rise by about 3 ¼ % in 2007, which is still faster than in the average of the last ten years. World trade will rise by 7 ½ % in the coming two years. An oil price of 65 US-Dollar and an exchange rate between the Euro and the US-Dollar of 1.32 were assumed for both years 2007 and 2008. The real estate market in the USA continues to be a risk for...

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
This paper explains why banks hold a capital ratio in excess of regulatory requirements. We demonstrate that banks can use capital ratios as a strategic tool for renegotiating loans with borrowers. Since the ability of banks to commit to a harsh treatment of borrowers depends on the capital ratio in a non-monotonic way, a bank may be forced to exceed capital requirements.

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
We investigate whether the agenda of deepening the integration of the European financial sector may hurt innovation and growth in Europe. In particular we highlight the problems financial integration may create for breakthrough innovation. Financial integration, by escalating competition and consolidation in the European banking sector, may jeopardize the funding of radical innovators. However weighing the current evidence we conclude these problems may at most be transitory.

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
This paper evaluates the potential effects of the Basel II accord on preventing the transmission from currency crises to financial crises. By analyzing the case study of South Korea, it shows how mismatches on banks’ balance sheets were the primary cause for such a transmission, and models how Basel II would have affected those balance sheets. The paper shows that due to South Korea’s positive credit rating in the months leading up to the crisis, the regulatory capital reserves under Basel II would have been even lower than those under Basel I, and that therefore Basel II would have had adverse effects on the development of the crisis. In the second part, the article analyses whether the behavior of rating agencies has changed since their failure to predict the Asian crisis. The paper finds no robust econometric evidence that rating agencies have started to take micromismatches into account when assigning sovereign ratings. Thus, given the current approach of credit rating agencies, we have reservations concerning the effectiveness of Basel II to prevent the transmission from currency crises to banking crises, both for the case of South Korea and for potential future crises.

Implementing an International Lender of Last Resort
Tobias Knedlik
IWH Discussion Papers,
No. 20,
2006
Abstract
Current research discusses various general frameworks for installing an international lender of last resort (ILOLR). However, it remains unclear how the ILOLR should actually operate. This paper discusses six different options of construction of an ILOLR who supports central banks in the case of currency crises. The paper concludes that the cost efficient version of the ILOLR would be direct interventions by the IMF by the use of IMF resources and the right to dispose additional reserves from central banks. The paper considers measures of cost efficiency, such as cost of borrowing, intervention, and sterilization and moral hazard problems.

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.
