Finance and Growth in a Bank-Based Economy: Is It Quantity or Quality that Matters?
Michael Koetter, Michael Wedow
Journal of International Money and Finance,
No. 8,
2010
Abstract
Most finance–growth studies approximate the size of financial systems rather than the quality of intermediation to explain economic growth differentials. Furthermore, the neglect of systematic differences in cross-country studies could drive the result that finance matters. We suggest a measure of bank’s intermediation quality using bank-specific efficiency estimates and focus on the regions of one economy only: Germany. This quality measure has a significantly positive effect on growth. This result is robust to the exclusion of banks operating in multiple regions, controlling for the proximity of financial markets, when distinguishing different banking sectors active in Germany, and when excluding the structurally weaker East from the sample.

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.

Has the Euro Increased International Price Elasticities?
Oliver Holtemöller, Götz Zeddies
IWH Discussion Papers,
No. 18,
2010
published in: Empirica
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.

Wer zahlt für das schöne Leben? Technische Infrastruktur in Zeiten von Bevölkerungsrückgang am Beispiel von drei ostdeutschen Mittelstädten
C. Deilmann, I. Kropp, Peter Haug
Tagungsband Arbeitskreis Stadterneuerung an deutschsprachigen Hochschulen,
2010
Abstract
In cities with decreasing population there is an increasing concern about the future cost of technical infrastructure. A diminishing number of inhabitants will have to bear the costs of the public services provided by their community. Beyond the pure cost arithmetic the main research question of our project was how urban planning can contribute to alleviating the rising average cost per service unit (cbm, sqm). The study was carried out for three medium-sized cities in the eastern part of Germany with a time horizon of 2030. The focus is on water, sewage and communal roads.
The rather surprising result was that urban planning (attempts for densification, inner city development instead of extensivation of the urban fabric) has little effect on long-term cost compared to the unavoidable yearly renovation requirements of the technical infrastructure. Because of the dominant block of fixed cost in technical infrastructure systems, the demographic development is the main cost determinant. Therefore, in future a massive problem in financing today’s standard of public services will be imminent.

International Bank Portfolios: Short- and Long-Run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
No. 2,
2010
Abstract
International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.

Business Networks in the Leipzig, Dresden, Chemnitz and Halle Regions: Do Member Firms Locate in Spatial Proximity?
Gerhard Heimpold
Wirtschaft im Wandel,
No. 4,
2010
Abstract
The business landscape in East Germany mainly consists of small and medium-sized firms. This in mind, business networks may contribute to an improvement of the economic performance of firms which collaborate in business networks. For successful networking a mix of network members being locally concentrated on the one side and of partners from distant regions, especially from abroad, on the other side, is important. In regional economics, this duality is highlighted for two reasons: personal contacts of partners which are located in spatial proximity to each other may ease the transfer of tacit knowledge. The flow of tacit knowledge can be regarded as a factor which enhances innovation processes. However, the inclusion of partners from abroad is important, too. It facilitates access to the most advanced knowledge and technologies worldwide. The academic debate on networking regards a one-sided orientation on the local dimension of networking as risky due to possible lock-in effects. The empirical findings for 93 business networks existing in the regions of Leipzig, Dresden, Chemnitz and Halle, which are located in the southern part of East Germany, reveal a great proportion of network members concentrated locally: On average, this is the case with more than 50% of the network members. 10% of members are located in the other three city regions mentioned. More than one third of firms are located outside, in other German regions, of which around the half in the states of Saxony and Saxony-Anhalt. A minority of 2% is located abroad. However, for the transfer of externally existing knowledge other network members may be relevant, too. To illustrate: More than four fifths of the networks under investigation include public research units (universities etc.) which usually play an important role when it comes to an inter-regional and international knowledge transfer.

Specialization, Diversity, Competition and their Impact on Local Economic Growth in Germany
Martin T. W. Rosenfeld, Annette Illy, Michael Schwartz, Christoph Hornych
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on urban growth in Germany from 2003 to 2007. We test four elements simultaneously, that is sectoral specialization, diversification of economic activities, urban size as well as the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. The analysis covers manufacturing industries as well as service sectors. Most previous work produces inconsistent results and concentrates on localization economies and/or diversification, while urban size and the effect of local competition are widely ignored. Our regression results show a U-shaped relationship between localization economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city-level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former a U-shaped relationship is found whereas the effect is inversely U-shaped for the latter.

Change in East German Firm Level Export Determinants
Birgit Schultz
Wirtschaft im Wandel,
No. 3,
2010
Abstract
Exports have a ‘motor of growth’ status for the German economy. They both save and increase employment and provide wealth. However, only a minority of East German manufacturing and construction firms realize sales in foreign countries. The paper analyses for two points in time the influences of firm level export factors on the level of export activities of East German firms, and how the strength of the influence has changed over time. We found export sales especially in firms who are integrated in international corporate groups and are highly specialized. Economies of scale (firm size) increase the export share. Additionally, export sales also depend on wages. These findings are in line with current analysis in the field of international trade. While the above factors are found to be stable over time some others have changed in importance. In 2000 the industrial sector and the unit labor costs were important factors in determining export activities. In 2008 these factors have lost importance. Instead, human capital and investments have achieved significance.
