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.

IT Use, Productivity, and Market Power in Banking
Michael Koetter, Felix Noth
Journal of Financial Stability,
No. 4,
2013
Abstract
Information management is a core process in banking that can resolve information asymmetries and thereby help to mitigate competitive pressure. We test if the use of information technology (IT) contributes to bank output, and how IT-augmented bank productivity relates to differences in market power. Detailed bank-level information on the use of IT reveals a substantial upward bias in bank productivity estimates when ignoring banks’ IT expenditures. IT-augmented bank productivity correlates positively with Lerner markups. A mere increase in IT expenditures, however, reduces markups. Results hold across a range of bank output definitions and productivity estimation methods.

What Do We Learn from Schumpeterian Growth Theory?

Abstract
Schumpeterian growth theory has operationalized Schumpeter’s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process that could not be properly addressed by alternative theories. In this survey, we focus on four important aspects, namely: (i) the role of competition and market structure; (ii) firm dynamics; (iii) the relationship between growth and development with the notion of appropriate growth institutions; and (iv) the emergence and impact of long-term technological waves. In each case, Schumpeterian growth theory delivers predictions that distinguish it from other growth models and which can be tested using micro data.

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.

IWH-Industrieumfrage im dritten Quartal 2013: Optimistische Aussichten erwärmen das Geschäftsklima

Abstract
Im Verarbeitenden Gewerbe Ostdeutschlands hellt sich die konjunkturelle Stimmung auf. Darauf verweisen die Ergebnisse der IWH-Industrieumfrage unter rund 300 Unternehmen. Dieser Befund ist weniger der Beurteilung der aktuellen Lage geschuldet, obgleich sie in der Industrie insgesamt drei Saldenpunkte höher liegt als im Vorquartal. Eine spürbare Verbesserung zeigt sich vielmehr bei den Erwartungen an die Geschäfte in den nächsten sechs Monaten. Diese optimistischen Einschätzungen teilen alle fachlichen Hauptgruppen, wenn auch in unterschiedlichem Ausmaß.

IWH-Bauumfrage im dritten Quartal 2013: Baugeschäfte deutlich im Aufwind

Abstract
Das Geschäftsklima unter mehr als 300 Unternehmen im ostdeutschen Baugewerbe hat sich laut IWH-Umfrage im dritten Quartal 2013 nochmals deutlich verbessert. Maßgeblich war eine von den Unternehmen gemeldete Verbesserung der Geschäftslage. Wesentlich dazu beigetragen haben Aufholeffekte nach derwitterungsbedingten Produktionsschwäche zu Jahresbeginn, die sich wegen des Hochwassers vor allem in den Regionen Sachsens und Sachsen-Anhalts noch in den Spätsommer hineingezogenen haben. Dazu kommen akute, flutbedingte Sanierungsarbeiten, angesichts derer sich die Auftragslage bis zuletzt auf hohem Niveau gehalten hat.
