Ineffiziente Strukturen in der deutschen Kommunal-
wirtschaft? – Das Beispiel der Trinkwasserversorgung in Ostdeutschland
Peter Haug
Wirtschaft im Wandel,
Nr. 2,
2006
Abstract
Die kleinteilig strukturierte deutsche Wasserwirtschaft wird von Ökonomen gerne als Beispiel für erhebliche Effizienzsteigerungspotentiale durch Unternehmenskonzentration angesehen, was sich beispielsweise mit der Ausnutzung von Größenvorteilen (economies of scale) und folglich einer kostengünstigeren Versorgung der Bevölkerung rechtfertigen lasse. Demgegenüber stehen aber die Ergebnisse etlicher empirischer Untersuchungen im Ausland, deren Befunde keine eindeutigen Rückschlüsse auf das Vorhandensein von Größenvorteilen in der öffentlichen Wasserversorgung zulassen. Eine aktuelle Untersuchung des IWH für die ostdeutsche Wasserwirtschaft liefert nun Ergebnisse einer Effizienzanalyse für deutsche Wasserversorger. Zu diesem Zweck wurde eine Data-Envelopment- Analyse (DEA) durchgeführt, wobei hier das Hauptaugenmerk auf der Abhängigkeit der sog. Skaleneffizienz von der Unternehmensgröße lag. Zur Absicherung der Ergebnisse wurden außerdem die Parameter einer aggregierten Produktionsfunktion der Wasserversorger mittels Regressionsanalyse geschätzt und daraus Rückschlüsse auf die Skalenelastizität gezogen. Die Ergebnisse der Data Envelopment Analyse legen nahe, daß nur sehr kleine Wasserversorger (jährliche Wasserabgabe weniger als 0,5 Mio. m3) mit Effizienzgewinnen durch Unternehmenszusammenschlüsse oder andere Formen der Ausweitung der Wasserabgabemenge rechnen können. Die Schätzergebnisse der aggregierten Produktionsfunktion bestätigten die Hypothese vom Vorliegen von signifikanten Größenvorteilen in der ostdeutschen Wasserversorgung ebenfalls nicht. Unter dem Gesichtspunkt einer möglichst kostengünstigen Versorgung der Bevölkerung durch Nutzung potentieller Größenvorteile kann zumindest auf der Basis dieser Ergebnisse und in Bezug auf die Trinkwasserversorgung nur eine flexiblere Handhabung, nicht jedoch eine Aufhebung des Örtlichkeitsprinzips der kommunalen Wirtschaftstätigkeit befürwortet werden.

Factors accounting for the enactment of a competition law – an empirical analysis
Franz Kronthaler, Johannes Stephan
Einzelveröffentlichungen,
Nr. 6,
2005
Abstract
The paper is concerned with the factors that account for decisions to enact a national competition law. In a first step, the paper updates and enlarges the existing data bases of countries that have enacted a competition law. The paper then identifies and discusses possible factors that influence the decision to enact a competition law. In a third step, the method of panel-data logit analysis is employed to test a set of hypothesis pertaining to the factors across the time dimension and across countries. The results of this analysis are interpreted in terms of significance and in terms of the sign of their influence on the probability of a country to enact. Given generality of the analysis, the results can shed light on the probability of individual countries, and in particular developing countries, to actually take the step of enactment.

Eastern Germany in the process of catching-up: the role of foreign and Western German investors in technological renewal
Jutta Günther, Oliver Gebhardt
Eastern European Economics,
Nr. 3,
2005
Abstract
Foreign direct investment as a means to support system transformation and the ongoing process of catching-up development has caught researcher’s attention for a number of Central and Eastern European countries. Not much research, however, has been carried out for East Germany in this respect although FDI plays an important role in East Germany too. Descriptive analysis by the use of unique survey data shows that foreign and West German affiliates perform much better with respect to technological capability and labor productivity than domestic companies in East Germany. The results of the regression analysis, however, show that it is not the status of ownership as such that forms a significant determinant of innovativeness in East Germany but rather general firms specific characteristics attached to it such as firm size, export-intensity, technical state of the equipment, and R&D activities. Due to the fact that foreign and West German affiliates perform better with respect to exactly all of these characteristics, they can be considered as a means to support the process of technological renewal and economic development.

Cross-border Banking and Transmission Mechanisms in Europe: Evidence from German Data
Claudia M. Buch
Applied Financial Economics,
Nr. 16,
2004
Abstract
International activities of commercial banks play a potential role for the transmission of shocks across countries. This paper presents stylized facts of the integration of European banking markets and analyses the potential of banks to transmit shocks across countries. Although the openness of banking systems has increased, bilateral financial linkages among EU countries are relatively small. The exceptions are claims of German banks on a number of smaller countries. These data are used for an analysis of the determinants of cross-border lending patterns.

Technological capability of foreign and West German investors in East Germany
Jutta Günther
IWH Discussion Papers,
Nr. 189,
2004
Abstract
Foreign direct investment (FDI) plays an important role for countries or regions in the process of economic catching-up since it is assumed – among other things – that FDI brings in new production technology and knowledge. This paper gives an overview about the development of FDI in East Germany based on official data provided by the Federal Bank of Germany. The investigation also includes a comparison of FDI in East Germany to Central East European countries. But the main focus of the paper is an analysis of the technological capability comparing majority foreign and West German owned firms to majority East German owned firms. It shows that foreign and West German subsidiaries in East Germany are indeed characterized by superior technological capability with respect to all indicators looked at (product innovation, research & development, organizational changes etc.).

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan, Karin Szalai
IWH Discussion Papers,
Nr. 183,
2003
Abstract
Industrial productivity levels of formerly socialist economies in Central East Europe (including East Germany) are considerably lower than in the more mature Western economies. This research aims at assessing the reasons for lower productivities at the firm level: what are the firm-specific determinants of productivity gaps. To assess this, we have conducted an extensive field study and focussed on a selection of two important manufacturing industries, namely machinery manufacturers and furniture manufacturers, and on the construction industry. Using the data generated in field work, we test a set of determinant-candidates which were derived from theory and prior research in that topic. Our analysis uses the simplest version of the matched-pair approach, in which first hypothesis about relevant productivity level-determinants are tested. In a second step, positively tested hypothesis are further assessed in terms of whether they also constitute firm-specific determinants of the apparent gaps between the firms in our Eastern and such in our Western panels. Our results suggest that the quality of human capital plays an important role in all three industrial branches assessed. Amongst manufacturing firms, networking activities and the use of modern technologies for communication are important reasons for the lower levels of labour productivity in the East. The intensity of long-term strategic planning on behalf of the management turned out to be relevant only for machinery manufacturers. Product and process innovations unexpectedly exhibit an ambiguous picture, as did the extent of specialisation on a small number of products in the firms’ portfolio and the intensity of competition.

Spillover Effects and R&D-Cooperations - The Influence of Market Structure
Anita Wölfl
IWH Discussion Papers,
Nr. 122,
2000
Abstract
This paper examines empirically the role of market structure for the influence of spill-over effects on R&D-cooperations. The results of a microeconometric analysis, based on firm data on innovation, let in general presume that with intensified competition also the influence of spillovers on R&D-cooperation increases. However, competition seems to induce firms to search for effective firm-specific appropriation facilities first. Spillovers that are sufficiently high such that the internalisation effect from R&D-cooperation more than outweighs the competitive effect from research, only arise whenever firms are not able to protect their research results through any appropriation facility. Additionally, there is some evidence that spillover effects may even hinder firms from cooperating in R&D when there is intensive competition on the research stage.

Labor Market Analysis and Public Policy: The Case of Morocco
Guillermo Hakim, Julia Lane, Javier Miranda
World Bank Economic Review,
Nr. 3,
1999
Abstract
This article uses detailed industry and household data to understand why Morocco's labor market performed poorly in 1985–95. The data indicate that marked structural changes and weak demand in the product market were responsible. This article makes two contributions to the literature. The first is specific: it underscores that the demand for labor is a derived demand and that the performance of the product market is an important determinant of the performance of the labor market. The second is more general: it demonstrates that this kind of microeconomic analysis, using data sets that are often available in developing countries, can inform policy design.
