Longterm development of return on assets – an empirical panel data analysis

Abstract
One of the basic propositions of economic theory is the fact that competition does not allow permanent very high or very low returns. But how can the permanent surplus gain of a monopolist be distinguished from innovation gains? In which markets is a regulatory interference necessary? Contrary to the static analysis, the concept of dynamic competition explicitly considers the temporal development of return and gain. An entrepreneur can achieve an advantage over the competitors through new products or new production processes. Hence arising innovation gains function as incentives for imitators to join the development which in turn leads to a reduction of the surplus gains. Thus, these gains are not contradictory to an effective competition. On the basis of annual balance sheets of German firms, this article analyses the temporal development of returns on assets. It is to evaluate whether the adaptation process assumed by Schumpeter that matches very high and very low gains with a longterm level can be confirmed, and how fast this process works. The average industry returns of the manufacturing industry show a convergence to a longterm level. During this process, an average of 40% of the deviation from the longterm level are melted every year. However, the analysis of company returns shows longterm differences. The adaptation rate of companies, 50%, is significantly higher compared to the industry value. The analysis of the connection between the adaptation rate and the longterm return level of companies proves that companies which face above-average competition strength obtain a higher longterm return level than other companies. When firms operate within markets with high stress of competition they do not achieve below-average returns but rather significantly above-average returns in the long term.

Workplace Equipment and Workplace Gap by Gender in East and West Germany
Hans-Ulrich Brautzsch, Johann Fuchs, Cornelia Lang
IWH Discussion Papers,
No. 9,
2006
Abstract
The paper investigates (a) the number and structure of available jobs by gender in East and West Germany, (b) the gap between the supply and demand of jobs by gender in both regions and (c) the reasons for the wider “job gap” in East Germany compared with West Germany. The paper uses data from the Regional National Accounts and the Federal Labor Office. The analysis shows no significant difference in the number of jobs per 1000 persons in working age between East and West Germany. For women, the East German economy offers more jobs. Nevertheless, the gap between labour demand and the supply of jobs is wider in East Germany. This is caused not only by problems concerning the production structure, but also by the significantly higher partizipation rate of women in the labor market. Reasons are the traditional behaviour of East German woman and – compared with West Germany – the considerably lower household income.

Economies of Scope in European Railways: An Efficiency Analysis
Christian Growitsch, Heike Wetzel
IWH Discussion Papers,
No. 5,
2006
Abstract
In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies – companies owning a network and providing transport services – argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realise economies of joint production and, thus, produce railway services on a higher level of efficiency. To determine whether joint or separate production is more efficient we apply a Data Envelopment Analysis super-efficiency bootstrapping model which relates the efficiency for integrated production to a virtual reference set consisting of the separated production technology. Our findings are that in a majority of European Railway companies exist economies of scope.

Inefficient structures in the German municipal economy? The example of East German drinking water supply
Peter Haug
Wirtschaft im Wandel,
No. 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 < 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
One-off Publications,
No. 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,
No. 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,
No. 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.

The effects of demographic changes on the level and structure of private consumption - a forecast for Germany until 2050 -
Harald Lehmann
IWH Discussion Papers,
No. 195,
2004
Abstract
This thesis analyzes the impact of different demografic scenarios on level and composition of private consumption in Germany. The analysis is based on the current household budget survey (Einkommens- und Verbrauchsstichprobe 1998) whose datas are adapted to the concepts of national accounting. Therefore households have to be defined by demografic aspects to investigate their consumption behavior. In the next step this will be used to forecast the effects of an aging population on private consumption by utilize a shift share analysis. The results lay open that the demografic impact is minor compared to economic factors influencing the composition of private consumption. This holds also in regard to the development of the absolute level of private consumption.

Technological capability of foreign and West German investors in East Germany
Jutta Günther
IWH Discussion Papers,
No. 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,
No. 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.
