Nr. 6,
2006
Abstract
This study investigates whether forming shared ATM networks has yielded positive benefits for banks in Turkey by increasing their productive efficiency. Using a Data Envelopment Analysis (DEA) approach, pure technical and scale efficiency scores of Turkish banks are estimated and analysed for the period 2000–2003. The results suggest that although it is possible to realize positive effects through ATM sharing arrangements, there are multiple factors that determine which banks realize such benefits. The geographical distribution of shared ATMs between urban and rural markets and the level of competition between banks within urban areas are shown to be important determinants of differences in bank efficiency. This discrepancy between the gains associated with ATM sharing may have important implications concerning the adoption and sharing of new technology by banks in developing countries.

Cross-border Bank Contagion in Europe
Reint E. Gropp, M. Lo Duca, Jukka M. Vesala
ECB Working Paper, No. 662,
Nr. 662,
2006
Abstract
This paper analyses cross-border contagion in a sample of European banks from January 1994 to January 2003. We use a multinomial logit model to estimate the number of banks in a given country that experience a large shock on the same day (“coexceedances“) as a function of variables measuring common shocks and lagged coexceedances in other countries. Large shocks are measured by the bottom 95th percentile of the distribution of the daily percentage change in the distance to default of the bank. We find evidence in favour of significant cross-border contagion. We also find some evidence that since the introduction of the euro cross-border contagion may have increased. The results seem to be very robust to changes in the specification.

Abstract
Herr Trichet hat die Europäer auf Zinserhöhungen ab Anfang August eingestellt. Die Ankündigung weiterer Zinsanhebungen wird mit den gestiegenen Inflationsrisiken im Euro-Raum begründet. Die Furcht vor einer höheren Inflation haben die Zentralbanker ausschließlich aus der monetären Analyse gewonnen, d. h. aus der Betrachtung der Geldmengen- und Kreditentwicklung im Euro-Raum. Sie wird quantitativ mit einem Modell unterlegt, welches einen engen Zusammenhang zwischen Geldmengenwachstum und folgender Inflation postuliert. Das Prognosemodell hat in der Vergangenheit die tatsächliche Inflationsrate aber meistens überzeichnet, manchmal auch unterzeichnet. Die Abweichungen liegen zwischen -0,2 und 0,5 Prozentpunkte, was bei einem Inflationsziel von 2% eine durchaus beträchtliche Fehlerquote ist und damit zu Fehlentscheidungen beitragen kann.

Clustering or Competition? The Foreign Investment Behavior of German Banks
Claudia M. Buch, A. Lipponer
International Journal of Central Banking,
2006
Abstract
Banks often concentrate their foreign direct investment (FDI) in certain countries. This clustering of activities could reflect either the attractiveness of a particular country or agglomeration effects. To find out which of the two phenomena dominates, we need to control for country-specific factors. We use new bank-level data on German banks’ FDI for the 1996-2003 period.We test whether the presence of other banks has a positive impact on the entry of new banks. Once we control for the attractiveness of a country through fixed effects, the negative impact of competition dominates. Hence, pure clustering effects are rather unimportant.

Entry and Strategic Information Display in Credit Markets
Jan Bouckaert, Hans Degryse
Economic Journal,
Nr. 513,
2006
Abstract
In many countries, lenders voluntarily provide information about their borrowers to private credit registries. A recent World Bank survey reveals that the display of a lender's own borrower information is often not reciprocated. That is, access to these registries does not require the prior provision of proprietary data. We argue that incumbent lenders release information about a portion of their profitable borrowers for strategic reasons. The reasoning is that the pool of unreleased borrowers becomes characterised by a severe adverse selection problem. This prevents the entrants from bidding for all the incumbent's profitable borrowers and reduces their scale of entry.

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.

Forced to Freedom? Empirical Relations between Aid and Economic Freedom
Tobias Knedlik, Franz Kronthaler
IWH Discussion Papers,
Nr. 8,
2006
Abstract
The paper explores the relationships between economic freedom on the one side and development aid and IMF credit as approximation for conditional aid on the other side. After a short review of current literature on the issue of economic development, economic freedom, aid, and IMF credit, the paper develops a simple panel regression model to evaluate the relationship between “economic freedom” as dependent variable and “aid” and “IMF credit” as independent variables. The estimation is based upon data taken from the World Bank’s World Development Indicators and the Heritage Index of Economic Freedom. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that aid is not contributing to economic freedom. The estimation results suggest that, firstly, aid is positively correlated with economic freedom, and secondly, that IMF credit is negatively correlated with economic freedom. Taking IMF credit as proxy for conditional aid, we conclude that for the period of observation it could not be shown that countries can be forced to economic freedom by aid conditions.

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.

Wissenskomplementarität und Produktivitätswachstum in ausländischen Tochterunternehmen in Mittel- und Osteuropa

Wirtschaft im Wandel,
Nr. 3,
2006
Abstract
Multinationale Unternehmen haben sich in Mittelund Osteuropa angesiedelt, um zum einen am Markt präsent zu sein und zum anderen den Standort als Basis für den internationalen Handel zu nutzen. Marktpräsenz hat sich als Motiv für Neuansiedlungen weitestgehend erschöpft. Zeitgleich konkurriert Mittel- und Osteuropa verstärkt mit asiatischen Ökonomien als Produktionsstandort. Die Ressource Wissen stellt ein zusätzliches entscheidendes Motiv für Investitionen dar. Multinationale Unternehmen übertragen spezifisches Wissen an einen anderen Unternehmensteil, damit dieser seine Funktion innerhalb des Konzerns erfüllen kann. Der effiziente Transfer kann durch die Beschaffenheit des Wissens, geographische und sprachliche Barrieren aber auch durch unzureichende absorptive Kapazität im Tochterunternehmen behindert werden. D. h., Tochterunternehmen müssen komplementäres Wissen und Fähigkeiten besitzen, um das externe Wissen produktiv absorbieren zu können. Der vorliegende Beitrag untersucht anhand eines Mikrodatensatzes in fünf EU-Beitrittsländern den Zusammenhang zwischen komplementärem Wissen und Produktivitätswachstum. Es kann festgestellt werde, daß ausländische Tochterbetriebe von direktem Wissenstransfer profitieren und lokales Wissen ebenfalls einen positiven Effekt auf das Produktivitätswachstum hat. Es werden zwei dominierende Typen der Wissenskomplementarität identifiziert. Bei Typ (I) transferiert der ausländische Investor technologisches Kernwissen und das Tochterunternehmen besitzt komplementäres Wissen in der Anwendung. Bei Typ (II) ist technologisches Kernwissen auf Mutter- und Tochterunternehmen komplementär verteilt. Aus der Forschung kann geschlußfolgert werden, daß es für die Länder Mittel- und Osteuropas von Bedeutung ist, die Humankapitalbasis ausreichend zu entwickeln, um in Zukunft nicht vom technologischen Wissenstransfer durch ausländische Investitionen ausgeschlossen zu werden.
