A New Metric for Banking Integration in Europe

Abstract
Most observers have concluded that while money markets and government bond markets are rapidly integrating following the introduction of the common currency in the euro area, there is little evidence that a similar integration process is taking place for retail banking. Data on cross-border retail bank flows, cross-border bank mergers and the law of one price reveal no evidence of integration in retail banking. This paper shows that the previous tests of bank integration are weak in that they are not based on an equilibrium concept and are neither necessary nor sufficient statistics for bank integration. The paper proposes a new test of integration based on convergence in banks' profitability. The new test emphasises the role of an active market for corporate control and of competition in banking integration. European listed banks profitability appears to converge to a common level. There is weak evidence that competition eliminates high profits for these banks, and underperforming banks tend to show improved profitability. Unlisted European banks differ markedly. Their profits show no tendency to revert to a common target rate of profitability. Overall, the banking market in Europe appears far from being integrated. In contrast, in the U.S. both listed and unlisted commercial banks profits converge to the same target, and high profit banks see their profits driven down quickly.

A Dynamic Approach to Interest Rate Convergence in Selected Euro-candidate Countries
Hubert Gabrisch, Lucjan T. Orlowski
IWH Discussion Papers,
Nr. 10,
2009
Abstract
We advocate a dynamic approach to monetary convergence to a common currency that is based on the analysis of financial system stability. Accordingly, we empirically test volatility dynamics of the ten-year sovereign bond yields of the 2004 EU accession countries in relation to the eurozone yields during the January 2, 2001 untill January 22, 2009 sample period. Our results show a varied degree of bond yield co-movements, the most pronounced for the Czech Republic, Slovenia and Poland, and weaker for Hungary and Slovakia. However, since the EU accession, we find some divergence of relative bond yields. We argue that a ‘static’ specification of the Maastricht criterion for long-term bond yields is not fully conducive for advancing stability of financial systems in the euro-candidate countries.

Is the European Monetary Union an Endogenous Currency Area? The Example of the Labor Markets
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
Nr. 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,
Nr. 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.

Signaling Currency Crises in South Africa
Tobias Knedlik
IWH Discussion Papers,
Nr. 19,
2006
Abstract
Currency crises episodes of 1996, 1998, and 2001 are used to identify common country specific causes of currency crises in South Africa. The paper identifies crises by the use of an Exchange Market Pressure (EMP) index as introduced by Eichengreen, Rose and Wyplosz (1996). It extends the Signals Approach introduced by Kaminsky and Reinhart (1996, 1998) by developing a composite indicator in order to measure the evolution of currency crisis risk in South Africa. The analysis considers the standard suspects from international currency crises and country specifics as identified by the Myburgh Commission (2002) and current literature as potentially relevant indicators.

Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
Botswana Journal of Economics,
Nr. 3,
2006
Abstract
The paper elaborates on the appropriateness of a potentially enlarged Common Monetary Area in Southern Africa including Botswana and Mozambique. The theory of optimum currency areas including some extensions by accounting for costs of non-integration and considering the external relations of currency areas are presented. Various indicators such as the structure of the economies, interest rates, inflation rates, exchange rates, factor mobility and trading partners are observed empirically. The paper concludes that current changes in the exchange rate policy of Botswana are expected to lead to increasing, though already high, convergence with CMA countries. Botswana is therefore an appropriate candidate for CMA enlargement. Mozambique is converging towards South Africa but still remains on a lower level. Taking into account the costs of non-integration, however, the target of integration should be formulated for the medium term.

Does Transparency of Central Banks produce Multiple Equilibria on Currency Markets?
Axel Lindner
Scandinavian Journal of Economics,
Nr. 1,
2006
Abstract
A recent strand of literature shows that multiple equilibria in models of markets for pegged currencies vanish if there is slightly diverse information among traders; see Morris and Shin (2001). It is known that this approach works only if the common knowledge in the market is not too precise. This has led to the conclusion that central banks should try to avoid making their information common knowledge. We develop a model in which more transparency of the central bank implies better private information, because each trader utilises public information according to her own private information. Thus, transparency makes multiple equilibria less likely.

Macroeconomic Modelling of the German Economy in the Framework of Euroland
Rüdiger Pohl, Heinz P. Galler
Schriften des IWH,
Nr. 11,
2002
Abstract
An attempt to develop a new macroeconometric model for Germany is confronted with several questions that range from the general rationality of such an approach to specific problems of an appropriate model structure. One important aspect of this discussion is the introduction of the Euro as a common currency of the European monetary union. This institutional change may result in structural breaks due to changing behavior of economic agents. In addition, the definition of the spatial unit that is appropriate for modelling becomes a problem. Additional problems come from the introduction of the European Single Market and the increasing international economic integration not only within the European union but also beyond its borders. And in the case of Germany, the unification of the West and the East demand special attention. Last but not least, the harmonization of national accounting for the member states of the European Union has to be dealt with. Thus, the introduction of the Euro as a common currency is just one problem besides others that must be addressed.
