Changing Forces of Gravity: How the Crisis Affected International Banking

IWH Discussion Papers,
No. 15,

Abstract
The global financial crisis has brought to an end a rather unprecedented period of banks’ international expansion. We analyze the effects of the crisis on international banking. Using a detailed dataset on the international assets of all German banks with foreign affiliates for the years 2002-2011, we study bank internationalization before and during the crisis. Our data allow analyzing not only the international assets of the banks’ headquarters but also of their foreign affiliates. We show that banks have lowered their international assets, both along the extensive and the intensive margin. This withdrawal from foreign markets is the result of changing market conditions, of policy interventions, and of a weakly increasing sensitivity of banks to financial frictions.

Has Labor Income Become More Volatile? Evidence from International Industry-Level Data
Claudia M. Buch
German Economic Review,
No. 4,
2013
Abstract
Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry-specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross-sectional heterogeneity is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear-cut impact.

Granularity in Banking and Growth: Does Financial Openness Matter?
Franziska Bremus, Claudia M. Buch
IWH Discussion Papers,
No. 14,
2013
Abstract
We explore the impact of large banks and of financial openness for aggregate growth. Large banks matter because of granular effects: if markets are very concentrated in terms of the size distribution of banks, idiosyncratic shocks at the bank-level do not cancel out in the aggregate but can affect macroeconomic outcomes. Financial openness may affect GDP growth in and of itself, and it may also influence concentration in banking and thus the impact of bank-specific shocks for the aggregate economy. To test these relationships, we use different measures of de jure and de facto financial openness in a linked micro-macro panel dataset. Our research has three main findings: First, bank-level shocks significantly impact on GDP. Second, financial openness lowers GDP growth. Third, granular effects tend to be stronger in financially closed economies.

Towards Deeper Financial Integration in Europe: What the Banking Union Can Contribute
Claudia M. Buch, T. Körner, Benjamin Weigert
IWH Discussion Papers,
No. 13,
2013
Abstract
The agreement to establish a Single Supervisory Mechanism in Europe is a major step towards a Banking Union, consisting of centralized powers for the supervision of banks, the restructuring and resolution of distressed banks, and a common deposit insurance system. In this paper, we argue that the Banking Union is a necessary complement to the common currency and the Internal Market for capital. However, due care needs to be taken that steps towards a Banking Union are taken in the right sequence and that liability and control remain at the same level throughout. The following elements are important. First, establishing a Single Supervisory Mechanism under the roof of the ECB and within the framework of the current EU treaties does not ensure a sufficient degree of independence of supervision and monetary policy. Second, a European institution for the restructuring and resolution of banks should be established and equipped with sufficient powers. Third, a fiscal backstop for bank restructuring is needed. The ESM can play a role but additional fiscal burden sharing agreements are needed. Direct recapitalization of banks through the ESM should not be possible until legacy assets on banks’ balance sheets have been cleaned up. Fourth, introducing European-wide deposit insurance in the current situation would entail the mutualisation of legacy assets, thus contributing to moral hazard.

Abstract
Für die deutsche Wirtschaft stehen die Zeichen auf Erholung. Das reale Bruttoinlandsprodukt zog nach einem Rückgang im vergangenen Winterhalbjahr im Sommer 2013 wieder an. Das preisbereinigte Bruttoinlandsprodukt dürfte im Jahr 2013 um 0,6% und im Jahr 2014 um 2% zulegen. Während die Arbeitslosenquote im Jahr 2014 zurückgeht, wird sich die Verbraucherpreisinflation etwas beschleunigen.

Konjunktur aktuell: Deutsche Wirtschaft erholt sich seit dem Frühjahr
Konjunktur aktuell,
No. 3,
2013
Abstract
Realwirtschaftliche Indikatoren deuten daraufhin, dass die Schwächephase der deutschen Konjunktur im Frühsommer ausläuft. So werden im Baugewerbe die witterungsbedingten Produktionsausfälle aufgeholt, und Aktivitäten zur Beseitigung der Hochwasserschäden kommen hinzu. Auch der private Konsum wirkt stützend. Das Bruttoinlandsprodukt wird im laufenden Jahr wohl um 0,7% und im kommenden Jahr um 2% steigen. Die Arbeitslosenquote wird im Jahr 2013 6,5% und im Jahr 2014 6,1% betragen. Der Finanzierungssaldo der öffentlichen Haushalte wird sich im Jahr 2013 bei einer leicht expansiv ausgerichteten Finanzpolitik geringfügig verschlechtern und im kommenden Jahr aufgrund wieder etwas stärker expandierender Einnahmen einen Überschuss in Höhe von 0,4% in Relation zum Bruttoinlandsprodukt aufweisen. Die Schulden- und Vertrauenskrise im Euroraum stellt nach wie vor das Hauptrisiko für die deutsche Konjunktur dar.

The New EU Countries and Euro Adoption
Hubert Gabrisch, Martina Kämpfe
Intereconomics,
No. 3,
2013
Abstract
In the new member states of the EU which have not yet adopted the euro, previous adoption strategies have come under scrutiny. The spillovers and contagion from the global financial crisis revealed a new threat to the countries’ real convergence goal, namely considerable vulnerability to the transmission of financial instability to the real economy. This paper demonstrates the existence of extreme risks for real convergence and argues in favour of a new adoption strategy which does not announce a target date for the currency changeover and which allows for more flexible and countercyclical monetary, fiscal and wage policies.
