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.

Konjunktur aktuell,
No. 4,
2013
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.

Disentangling Barriers to Internationalization
C. Arndt, Claudia M. Buch, A. Mattes
Canadian Journal of Economics,
No. 1,
2012
Abstract
Recent literature on multinational firms has focused on low productivity as a barrier to the internationalization of firms. But labour market frictions or financial constraints may also hamper internationalization. In order to assess the importance of these barriers, we present new empirical evidence on the extensive and intensive margin of exports and foreign direct investment (FDI) based on micro-level data of German firms. First, we find a positive impact of firm size and productivity on firms’ international activities. Second, labour market frictions can constitute barriers to foreign activities. Third, self-reported financial constraints have no impact on firms’ internationalization decisions.

Consumption Volatility and Financial Openness
Claudia M. Buch, S. Yener
Applied Economics,
2010
Abstract
Economic theory predicts that the integration of financial markets lowers the volatility of consumption. In this article, we study long-term trends in the consumption volatility of the G7 countries. Using different measures of financial openness, we find evidence that greater financial openness has been associated with lower consumption volatility. However, volatility of consumption relative to output has not declined.

Sovereign Credit Risk Co-movements in the Eurozone: Simple Interdependence or Contagion?
Manuel Buchholz, Lena Tonzer
UniCredit & Universities Foundation, Working Paper Series No. 47,
No. 47,
2013
published in: International Finance
Abstract
We investigate credit risk co-movements and contagion in sovereign debt markets of 17 industrialized countries for the period 2008-2012. We use dynamic conditional correlations of sovereign CDS spreads to detect contagion. This approach allows separating the channels through which contagion occurs from the determinants of simple interdependence. The results show that, first, sovereign credit risk comoves considerably, in particular among eurozone countries and during the sovereign debt crisis. Second, contagion cannot be attributed to one moment in time but varies across time and countries. Third, similarities in economic fundamentals, cross-country linkages in banking, and common market sentiment constitute the main channels of contagion.
