Der Euro als Triebfeder des deutschen Exports?
Götz Zeddies
List Forum für Wirtschafts- und Finanzpolitik,
No. 3,
2011
Abstract
The excessive accumulation of debt especially in the southern member states currently challenges European Monetary Union (EMU). Whereas for a long time, preventing a break-up of EMU was indisputable, in the meantime, voices were being raised claiming a withdrawal of Greece from the currency union. Especially in Germany, a withdrawal of individual members from the currency union (or even a complete break-up of EMU) is associated with economic disadvantages. Particularly, it is argued that EMU is of greatest utility for Germany due to the countries’ longstanding wage moderation and strong export orientation. Against this background, this paper analyzes the effects of a withdrawal of individual member states from the currency union on German exports. Thereby, it is assumed that a withdrawal of those countries from EMU would be accompanied by real devaluations. As the analyses show, the impact of a withdrawal of Ireland, Greece, Spain and Portugal from the currency union on German exports would be rather small. However, since European Monetary Union as a whole is still the most important foreign market for German manufacturers, a complete break-up of EMU could noticeably weaken German export performance.

Do Banks Benefit from Internationalization? Revisiting the Market Power-Risk Nexus
Claudia M. Buch, C. T. Koch, Michael Koetter
Abstract
Recent developments on international financial markets have called the benefits of
bank globalization into question. Large, internationally active banks have
acquired substantial market power, and international activities have not
necessarily made banks less risky. Yet, surprisingly little is known about the
actual link between bank internationalization, bank risk, and market power.
Analyzing this link is the purpose of this paper. We jointly estimate the
determinants of risk and market power of banks, and we analyze the effects of
changes in terms of the number of foreign countries (the extensive margin) and
the volume of foreign assets (the intensive margin). Our paper has four main
findings. First, there is a strong negative feedback effect between risk and market
power. Second, banks with higher shares of foreign assets, in particular those held
through foreign branches, have higher market power at home. Third, holding
assets in a large number of foreign countries tends to increase bank risk. Fourth,
the impact of internationalization differs across banks from different banking
groups and of different size.

Macroeconomic Shocks and Banks' Foreign Assets
Claudia M. Buch, K. Carstensen, A. Schertler
Journal of Money, Credit and Banking,
No. 1,
2010
Abstract
Recent developments in international financial markets have highlighted the role of banks in the transmission of shocks across borders. We employ dynamic panel methods for a sample of OECD countries to analyze whether banks' foreign assets react to macroeconomic shocks at home and abroad. We find that banks reduce their foreign assets in response to a relative increase in domestic interest rates, and they increase their foreign assets when the growth rate of world energy prices rises. The responses are characterized by a temporal overshooting and a dynamic adjustment process that extends over several quarters.

Margins of international banking: Is there a productivity pecking order in banking, too?
Claudia M. Buch
Bundesbank Discussion Paper 12/2009,
2009
Abstract
Modern trade theory emphasizes firm-level productivity differentials to explain
the cross-border activities of non-financial firms. This study tests whether a
productivity pecking order also determines international banking activities. Using
a novel dataset that contains all German banks’ international activities, we
estimate the ordered probability of a presence abroad (extensive margin) and the
volume of international assets (intensive margin). Methodologically, we enrich the
conventional Heckman selection model to account for the self-selection of banks
into different modes of foreign activities using an ordered probit. Four main
findings emerge. First, similar to results for non-financial firms, a productivity
pecking order drives bank internationalization. Second, only a few non-financial
firms engage in international trade, but many banks hold international assets, and
only a few large banks engage in foreign direct investment. Third, in addition to
productivity, risk factors matter for international banking. Fourth, gravity-type
variables have an important impact on international banking activities.

The role of banking portfolios in the transmission from the currency crises to banking crises - potential effects of Basel II
Tobias Knedlik, Johannes Ströbel
IWH Discussion Papers,
No. 21,
2006
Abstract
This paper evaluates the potential effects of the Basel II accord on preventing the transmission from currency crises to financial crises. By analyzing the case study of South Korea, it shows how mismatches on banks’ balance sheets were the primary cause for such a transmission, and models how Basel II would have affected those balance sheets. The paper shows that due to South Korea’s positive credit rating in the months leading up to the crisis, the regulatory capital reserves under Basel II would have been even lower than those under Basel I, and that therefore Basel II would have had adverse effects on the development of the crisis. In the second part, the article analyses whether the behavior of rating agencies has changed since their failure to predict the Asian crisis. The paper finds no robust econometric evidence that rating agencies have started to take micromismatches into account when assigning sovereign ratings. Thus, given the current approach of credit rating agencies, we have reservations concerning the effectiveness of Basel II to prevent the transmission from currency crises to banking crises, both for the case of South Korea and for potential future crises.

Signaling Currency Crises in South Africa
Tobias Knedlik
IWH Discussion Papers,
No. 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.

Heterogeneity in Lending and Sectoral Growth: Evidence from German Bank-level Data
A. Schertler, Claudia M. Buch, N. von Westernhagen
International Economics and Economic Policy,
2006
Abstract
This paper investigates whether heterogeneity across firms and banks matters for the impact of domestic sectoral growth on bank lending. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996–2002 period. Our results show that firm heterogeneity and bank heterogeneity affect how lending responds to domestic sectoral growth. We document that banks’ total lending to German firms reacts pro-cyclically to domestic sectoral growth, while lending exceeding a threshold of €1.5 million to German and foreign firms does not. Moreover, we document that the response of lending depends on bank characteristics such as the banking groups, the banks’ asset size, and the degree of sectoral specialization. We find that total domestic lending by savings banks and credit cooperatives (including their regional institutions), smaller banks, and banks that are highly specialized in specific sectors responds positively and, in relevant cases, more strongly to domestic sectoral growth.

Business Cycles and FDI: Evidence from German Sectoral Data
Claudia M. Buch, A. Lipponer
Review of World Economics,
No. 4,
2005
Abstract
Globalization has affected business cycle developments in OECD countries and has increased activities of firms across national borders. This paper analyzes whether these two developments are linked. We use a new firm-level data set on the foreign activities of German firms to test whether foreign activities are affected by business cycle developments. We aggregate the data by the sector of the reporting firm, the sector of the foreign affiliate, and the host country. Data are annual and cover the period 1989–2002. We find that German outward FDI increases in response to positive cyclical developments abroad and in response to a real depreciation of the domestic currency.
