IWH Discussion Papers,
No. 11,
2008
Abstract
This study argues that the severity of the current global financial crisis is strongly influenced by changeable allocations of the global savings. This process is named a “wandering asset bubble”. Since its original outbreak induced by the demise of the subprime mortgage market and the mortgage-backed securities in the U.S., this crisis has reverberated across other credit areas, structured financial products and global financial institutions. Four distinctive stages of the crisis are identified: the meltdown of the subprime mortgage market, spillovers into broader credit market, the liquidity crisis epitomized by the fallout of Bear Sterns with some contagion effects on other financial institutions, and the commodity price bubble. Monetary policy responses aimed at stabilizing financial markets are proposed.

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.

Schätzunsicherheit oder Korrelation, Welche Risikokomponente sollten Unternehmen bei der Bewertung von Kreditportfoliorisiken wann berücksichtigen?
Henry Dannenberg
IWH Discussion Papers,
No. 5,
2007
Abstract
The use of probability of default estimates to assess the risks of a credit portfolio should not ignore estimation uncertainty. The latter can be quantified by confidence intervals. But assumptions about dependencies of these intervals are inconsistent with assumptions of conventional credit portfolio models. Based on simulation studies this paper shows, that a model which include estimation uncertainty but ignore default correlation might estimate the real credit risk more correctly than a model that implicates default correlation but ignore estimation uncertainty. The latter is a trait of conventional credit portfolio models. In this paper quantifying of estimation uncertainty based on the idea of confidence intervals and the underlying probability distributions of these intervals.

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.

Cross-border Bank Contagion in Europe
Reint E. Gropp, M. Lo Duca, Jukka M. Vesala
ECB Working Paper, No. 662,
No. 662,
2006
Abstract
This paper analyses cross-border contagion in a sample of European banks from January 1994 to January 2003. We use a multinomial logit model to estimate the number of banks in a given country that experience a large shock on the same day (“coexceedances“) as a function of variables measuring common shocks and lagged coexceedances in other countries. Large shocks are measured by the bottom 95th percentile of the distribution of the daily percentage change in the distance to default of the bank. We find evidence in favour of significant cross-border contagion. We also find some evidence that since the introduction of the euro cross-border contagion may have increased. The results seem to be very robust to changes in the specification.

Heterogeneity in Lending and Sectoral Growth: Evidence from German Bank-level Data
A. Schertler, Claudia M. Buch, N. von Westernhagen
International Economics and Economic Policy,
2006
Abstract
This paper investigates whether heterogeneity across firms and banks matters for the impact of domestic sectoral growth on bank lending. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996–2002 period. Our results show that firm heterogeneity and bank heterogeneity affect how lending responds to domestic sectoral growth. We document that banks’ total lending to German firms reacts pro-cyclically to domestic sectoral growth, while lending exceeding a threshold of €1.5 million to German and foreign firms does not. Moreover, we document that the response of lending depends on bank characteristics such as the banking groups, the banks’ asset size, and the degree of sectoral specialization. We find that total domestic lending by savings banks and credit cooperatives (including their regional institutions), smaller banks, and banks that are highly specialized in specific sectors responds positively and, in relevant cases, more strongly to domestic sectoral growth.

Investment and Internal Finance: Asymmetric Information or Managerial Discretion?
Hans Degryse, Abe de Jong
International Journal of Industrial Organization,
No. 1,
2006
Abstract
This paper examines the investment-cash flow sensitivity of publicly listed firms in The Netherlands. Investment-cash flow sensitivities can be attributed to overinvestment resulting from the abuse of managerial discretion, but also to underinvestment due to information problems. The Dutch corporate governance structure presents a number of distinctive features, in particular the limited influence of shareholders, the presence of large blockholders, and the importance of bank ties. We expect that in The Netherlands, the managerial discretion problem is more important than the asymmetric information problem. We use Tobin's Q to discriminate between firms with these problems, where LOW Q firms face the managerial discretion problem and HIGH Q firms the asymmetric information problem. As hypothesized, we find substantially larger investment-cash flow sensitivity for LOW Q firms. Moreover, specifically in the LOW Q sample, we find that firms with higher (bank) debt have lower investment-cash flow sensitivity. This finding shows that leverage, and particularly bank debt, is a key disciplinary mechanism which reduces the managerial discretion problem.

Financial Openness and Business Cycle Volatility
Claudia M. Buch, Jörg Döpke, C. Pierdzioch
Journal of International Money and Finance,
No. 5,
2005
Abstract
This paper discusses whether the integration of international financial markets affects business cycle volatility. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock. Empirical evidence supports this conclusion. Our results also show that the link between business cycle volatility and financial openness has not been stable over time.

Exporting Financial Institutions Management via Foreign Direct Investment Mergers and Acquisitions
Allen N. Berger, Claudia M. Buch, G. DeLong
Journal of International Money and Finance,
No. 3,
2004
Abstract
We test the relevance of the new trade theory and the traditional theory of comparative advantage for explaining the geographic patterns of international M&As of financial institutions between 1985 and 2000. The data provide statistically significant support for both theories. We also find evidence that the U.S. has idiosyncratic comparative advantages at both exporting and importing financial institutions management.

Measurement of Contagion in Banks' Equity Prices
Reint E. Gropp, G. Moerman
Journal of International Money and Finance,
No. 3,
2004
Abstract
This paper uses the co-incidence of extreme shocks to banks’ risk to examine within-country and across country contagion among large EU banks. Banks’ risk is measured by the first difference of weekly distances to default and abnormal returns. Using Monte Carlo simulations, the paper examines whether the observed frequency of large shocks experienced by two or more banks simultaneously is consistent with the assumption of a multivariate normal or a student t distribution. Further, the paper proposes a simple metric, which is used to identify contagion from one bank to another and identify “systemically important” banks in the EU.
