Abstract
Integrated financial markets provide opportunities for expansion and improved risk sharing, but also pose threats of contagion risk through cross-border exposures. This paper examines cross-border contagion risk over the period 1999–2006. To that purpose we use aggregate cross-border exposures of 17 countries as reported in the Bank for International Settlements Consolidated Banking Statistics. We find that a shock that affects the liabilities of one country may undermine the stability of the entire financial system. Particularly, a shock wiping out 25% (35%) of US (UK) cross-border liabilities against non-US (non-UK) banks could lead to bank contagion eroding at least 94% (45%) of the recipient countries' banking assets. We also find that since 2006 a shock to Eastern Europe, Turkey and Russia affects most countries. Our simulations also reveal that the ‘speed of propagation of contagion’ has increased in recent years resulting in a higher number of directly exposed banking systems. Finally, we find that contagion is more widespread in geographical proximities.

International Bank Portfolios: Short- and Long-Run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
No. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.

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.

Is the European Monetary Union an Endogenous Currency Area? The Example of the Labor Markets
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 7,
2009
Abstract
Our study tries to find out whether wage dynamics between Euro member countries became more synchronized through the adoption of the common currency. We calculate bivarate correlation coefficients of wage and wage cost dynamics and run a model of endogenously induced changes of coefficients, which are explained by other variables being also endogenous: trade intensity, sectoral specialization, financial integration. We used a panel data structure to allow for cross-section weights for country-pair observations. We use instrumental variable regressions in order to disentangle exogenous from endogenous influences. We applied these techniques to real and nominal wage dynamics and to dynamics of unit labor costs. We found evidence for persistent asymmetries in nominal wage formation despite a single currency and monetary policy, responsible for diverging unit labor costs and for emerging trade imbalances among the EMU member countries.

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.

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.

International Financial Integration and Stability: On the Causes of the International Banking Crisis 2007/08 and Some Preliminary Lessons.
Diemo Dietrich, Achim Hauck
Wirtschaft im Wandel,
No. 5,
2008
Abstract
Die gemeinhin als „Subprime-Krise“ bezeichneten Turbulenzen auf den internationalen Finanzmärkten beherrschen, seitdem sich im vergangenen Sommer ihre ersten Symptome aufzeigten, weltweit die wirtschaftspolitische Diskussion. Dabei stand zunächst die Frage im Vordergrund, ob und welche Maßnahmen kurzfristig erforderlich sind, um das internationale Finanzsystem zu stabilisieren und mögliche negative realwirtschaftliche Auswirkungen der Krise zu begrenzen. In jüngerer Zeit wird darüber hinausgehend verstärkt diskutiert, welche grundsätzlichen Lehren aus den Ereignissen gezogen werden können und welche Konsequenzen sich für die zukünftige Ausgestaltung nationaler und internationaler Rahmenbedingungen für die internationale Finanzintegration ergeben. In der bisherigen Diskussion wurde eine Vielzahl unterschiedlicher Einzelfaktoren als ursächlich für die Krise betrachtet und mehr oder weniger isoliert voneinander hinsichtlich ihrer möglichen wirtschaftspolitischen Implikationen untersucht. Die Frage nach der Existenz einer gemeinsamen Quelle für diese vielen mutmaßlichen Gründe ist mithin bislang noch nicht in hinreichendem Maß beantwortet, sodass aus der Krise noch keine über Teilaspekte hinausgehende grundsätzlichen Erkenntnisse für die Wirtschaftspolitik abgeleitet werden konnten.
Der vorliegende Beitrag befasst sich zum einen mit der Frage nach der Hauptursache der Krise. Es wird aufgezeigt, dass sie zu einem bedeutenden Teil auf die Integration vormals peripherer und institutionell schwach entwickelter Volkswirtschaften in die Weltwirtschaft und die damit verbundenen globalen Ungleichgewichte zurückgeführt werden kann. Entsprechend ist die Krise nicht nur in ihrer Wirkung, sondern vor allem in ihrer Ursache ein globales und kein vorrangig US-amerikanisches Phänomen. Auf der Grundlage dieses Befunds werden vorläufige Lehren aus der Subprime-Krise für eine stabilitätsorientierte Wirtschaftspolitik in einer integrierten Weltwirtschaft gezogen.

The Euro and Cross-Border Banking: Evidence from Bilateral Data
S. Blank, Claudia M. Buch
Comparative Economic Studies,
No. 3,
2007
Abstract
Has the introduction of the Euro fostered financial integration in Europe? We answer this question using a data set of banks’ bilateral foreign assets and liabilities provided by the Bank for International Settlements. The data cover the pre-Euro period (1995–1998) and the post-Euro period (1999–2005). We use information from 10 OECD reporting countries and all OECD recipient countries. Gravity regressions show a positive and significant impact of the Euro on bilateral financial linkages. This effect is stronger and more robust for banks’ foreign assets than for their foreign liabilities.

Microeconometric Evaluation of Selected ESF-funded ALMP-Programmes
Eva Reinowski, Birgit Schultz
IWH Discussion Papers,
No. 17,
2006
Abstract
The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.

Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
No. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.
