Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses
Michael Koetter
Journal of Financial Services Research,
No. 2,
2006
Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.

Vielfältigkeit eines Hybridberufes: Mechatronikfacharbeiter nach der Ausbildung
Simone Scharfe, K. Tautenhahn
Externe Publikationen,
No. 8,
2006
Abstract
Im Rahmen des Modellprojektes „Verbundausbildung in neuen Berufen der Hochtechnologie“, das vom Sächsischen Staatsministerium für Wirtschaft und Arbeit initiiert wurde, schlossen im Zeitraum von 2002 bis 2004 insgesamt 302 Facharbeiter in den Berufen Mechatroniker, Mikrotechnologe, Chemie-, Physik- und Lacklaborant ihre Ausbildung erfolgreich ab. Das Modellprojekt und die wissenschaftliche Begleitung wurden aus Mitteln des Europäischen Sozialfonds und komplementären Landesmitteln des Freistaates Sachsen gefördert.
Zur Evaluierung des Modellprojektes befragte die wissenschaftliche Begleitung (vgl. Blum/ Scharfe/ Tautenhahn 2005) die Absolventen einige Monate nach Ausbildungsende zu verschiedenen Aspekten, wie bspw.
§ der rückblickenden Einschätzung der Ausbildung und des Modellprojektes,
§ der Bewertung ihrer Arbeitsmarktchancen,
§ dem beruflichen Verbleib sowie
§ der Bewertung der Praxistauglichkeit des erlernten Wissens.
Im vorliegenden Beitrag werden vor allem die Ergebnisse zu den letzten beiden Gesichtspunkten für die Mechatroniker, die mit 180 Absolventen die größte Gruppe im Modellprojekt stellten, thematisiert. Da der Beruf des Mechatronikers eine Brücke zwischen den Teilgebieten der Mechanik und der Elektronik schlagen sollte, wird im zweiten Teil der Ergebnisdarstellung untersucht, inwieweit sich dieser Brückenschlag in den tatsächlichen Einsatzgebieten der ehemaligen Auszubildenden widerspiegelt.

Microeconometric Evaluation of Selected ESF-funded ALMP-Programmes
Eva Reinowski, Birgit Schultz
IWH Discussion Papers,
No. 17,
2006
Abstract
The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.

Money and Credit Market Integration in an enlarging Euro Zone: Methodological Issues
Johannes Stephan, Jens Hölscher
European Economic Policies - Alteratives to Orthodox Analysis and Policy Concepts,
2006
Abstract
“The chapter discusses methodological issues of money and credit market integration within the context of an enlarging Euro area. Common methods of interest parity tests are rejected in favour of a comparison of nominal interest rates. Hölscher and Stephan find that from an institutional point of view the new EU member countries look under-banked, whereas interest rates are converging. As policy implication the paper argues for a Euro adoption of the new EU members rather sooner than later.“

The Effects of Shared ATM Networks on the Efficiency of Turkish Banks
H. Evren Damar
Applied Economics,
No. 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.

Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
No. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.

Who Invests in Training if Contracts are Temporary? - Empirical Evidence for Germany Using Selection Correction
Jan Sauermann
IWH Discussion Papers,
No. 14,
2006
Abstract
This study deals with the effect of fixed-term contracts on work-related training. Though previous studies found a negative effect of fixed-term contracts on the participation in training, from the theoretical point of view it is not clear whether workers with fixed-term contracts receive less or more training, compared to workers with permanent contracts. In addition to the existing strand of literature, we especially distinguish between employer- and employee-financed training in order to allow for diverging investment patterns of worker and firm. Using data from the German Socio-Economic Panel (GSOEP), we estimate a bivariate probit model to control for selection effects that may arise from unobservable factors, affecting both participation in training and holding fixed-term contracts. Finding negative effects for employer-sponsored, as well as for employee-sponsored training, leads us to conclude that workers with fixed-term contracts do not compensate for lower firm investments.

Signaling currency crises in South Africa
Tobias Knedlik
South African Reserve Bank: Macroeconomic Policy Challenges for South Africa Conference, South African Reserve Bank,
2006
Abstract
Diese Arbeit betrachtet die südafrikanischen Währungskrisenepisoden von 1996, 1998 und 2001, um gemeinsame länderspezifische Ursachen für Währungskrisen in Südafrika zu ermitteln. Die Identifikation der Währungskrisen erfolgt mittels des Exchange Market Pressure Indexes, welcher von Eichengreen, Rose und Wyplosz (1996) entwickelt wurde. Dann wird ein Signalansatz, basierend auf Kaminsky und Reinhart (1996, 1998) verwendet, um mit dessen Hilfe das Risiko für Währungskrisen in Südafrika zu evaluieren. Die Arbeit berücksichtigt als potentielle Einflussgrößen die üblichen Variablen aus der Währungskrisentheorie sowie länderspezifische Faktoren, welche sich aus dem Bericht der Myburgh Commission (2002) und aktueller Literatur ergeben.

Labor market balance: further deterioration of the labor market situation
Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 6,
2006
Abstract
Im Jahr 2005 hat sich infolge der Produktionsschwäche die an sich schon schwierige Lage auf dem Arbeitsmarkt nochmals verschlechtert. Die Zahl der Erwerbstätigen (Inland) nahm gegenüber dem Vorjahr um 74 000 Personen bzw. 1,3% ab. Nur durch die Ausweitung von staatlich subventionierten Ich-AGs (ca. +30 000) sowie der Bereitstellung von Arbeitsgelegenheiten (ca. +90 000), die beide statistisch den Erwerbstätigen zugeordnet werden, kam es zu keinem noch stärkeren Rückgang.
