Abstract
We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region. Different measures and estimation approaches lead to rather similar assessments. We find that both spillovers within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector R&D in the respective region. It is not the mere presence and size of public research institutions, but rather the intensity of interactions between private and public sector R&D that leads to high RIS efficiency. We find that relationship between the diversity of a regions’ industry structure and the efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.

Local Government Control and Efficiency of the Water Industry: An Empirical Analysis of Water Suppliers in East Germany
Peter Haug
IWH Discussion Papers,
Nr. 3,
2007
Abstract
The paper deals with the effects of local governments’ interference with business affairs of publicly owned utilities. A partial model is presented to illustrate the consequences of “democratic control” for the public managers’ effort and the efficiency of local public production. To check the theoretical results empirically, a two-stage data envelopment analysis (DEA) is carried out for a sample of East German water suppliers. The organisational form is used as a measure for the degree of municipal control. The results of the OLS- and Tobit regression indicate an efficiency-enhancing effect of organisational forms with less distinctive control options for local politicians.

Vertical Intra-industry Trade between EU and Accession Countries
Hubert Gabrisch
IWH Discussion Papers,
Nr. 12,
2006
Abstract
The paper analyses vertical intra-industry trade between EU and Accession countries, and concentrates on two country-specific determinants: Differences in personal income distribution and in technology. Both determinants have a strong link to national policies and to cross-border investment flows. In contrast to most other studies, income distribution is not seen as time-invariant variable, but as changing over time. What is new is also that differences in technology are tested in comparison with cost advantages from capital/labour ratios. The study applies panel estimation techniques with GLS. Results show country-pair fixed effects to be of high relevance for explaining vertical intraindustry trade. In addition, bilateral differences in personal income distribution and their changes are positive related to vertical intra-industry trade in this special regional integration framework; hence, distributional effects of policies matter. Also, technology differences turn out to be positively correlated with vertical intra-industry trade. However, the cost variable (here: relative GDP per capita) shows no clear picture, particularly not in combination with the technology variable.

Can Export Activities of Firms Contribute to the Catching-Up Process of Transitional Economies?
Brigitte Loose, Udo Ludwig
Can the transitional and development economies ever catch up? The Materials from The International Scientific Conference Cracow,
2006
Abstract
In contrast to the majority of the former centrally planned economies, the East German economy has suffered from enormous losses in the transformation process. In the study the question is analyzed whether exports can contribute to the catching-up process in transitional economies. Here it must be explained why the firms emerging out of the privatization process in economies in transition are successful if the export sector consists of small and medium sized enterprises. That is the case with East German manufacturing industry. The study is based on individual company data from the surveys of the East Germany's and North Rhine Westphalia's manufacturing industry between 1995 and 2001 stemming from official statistics.

Essays on Network Regulation – Theoretical and Empirical Evidence from the Electricity Supply Industry

Nr. 21,

Abstract
Mit dem Etablieren des gemeinsamen Europäischen Binnenmarktes im Laufe der 80er und 90er Jahre des vergangenen Jahrhunderts und dem damit verbundenen Wegfall von Handelsbarrieren und anderen Wettbewerbshemmnissen rückte die Liberalisierung sogenannter Netzindustrien in den Fokus der Europäischen Politik. Die Deregulierung solcher Sektoren mit physischer Netzinfrastruktur, insbesondere der Märkte für Strom, Gas, Telekommunikation und Schienenverkehr wurde zu einem wesentlichen Aspekt des Ziels der Förderung von Wettbewerb in der Europäischen Ökonomie. Die Einführung wettbewerblicher Strukturen in die ehemalig monopolistischen Netzindustrien bedingte die Notwendigkeit wettbewerbspolitischer Reformen auf nationaler und Europäischer Ebene. Insbesondere die Sicherstellung gleicher Wettbewerbsbedingungen und der Schutz der Verbraucher vor Marktmachtmißbrauch durch die etablierten Anbieter rückte in den Fokus der Wirtschaftspolitik und führte zum Aufbau sektorspezifischer Regulierungsregime. Diese unterscheiden sich deutlich sowohl sektoral wie im Hinblick auf nationale Ordnungsrahmen hinsichtlich ihrer Rahmenbedingungen, ihrer Methoden, ihrer Struktur und ihrer ökonomischen Wirkung. Der Austausch und die Übertragung von Erkenntnissen und Erfahrungen und die kontinuierliche Verbesserung bestehender institutioneller Arrangements sollte daher ein bedeutender Aspekt ökonomischer Forschung und staatlicher Wirtschaftspolitik sein. Die hier vorliegende Sammlung energieökonomischer Aufsätze zielt auf eben jenen Erkenntnistransfer ab. Dazu wird in den ersten beiden Artikeln ein spezifisches Regulierungsregime, der sogenannte verhandelte Netzzugang, und die damit verbundenen Erfahrungen aus dem deutschen Elektrizitätsmarkt vorgestellt. Ein dritter Aufsatz beschäftigt sich mit der Versorgungsqualität in Netzsektoren am Beispiel lokaler Stromverteilnetzbetreiber in einem europäischen Vergleich.

Industry Level Technology Gaps and Complementary Knowledge Stocks as Determinants of Intra-MNC Knowledge Flows
Björn Jindra, Johannes Stephan
East-West Journal of Economics and Business,
1 & 2
2005
Abstract
Pursuing a subsidiary level analysis, we this paper tests the ‘technology gap’ hypothesis in the context of intra-MNC knowledge flows. Furthermore, it introduces complementary knowledge stocks into the concept of absorptive capacity. A set of hypotheses is tested in sample 434 foreign subsidiaries based in Central and East Europe. We find partial support for the ‘technology gap’ hypothesis applied at industry level. Furthermore, subsidiaries’ complementary knowledge stocks increase the probability for corresponding knowledge inflows from the foreign parent.

Cross-border bank mergers: What lures the rare animal?
Claudia M. Buch, G. DeLong
Journal of Banking and Finance,
Nr. 9,
2004
Abstract
Although domestic mergers and acquisitions (M&As) in the financial services industry have increased steadily over the past two decades, international M&As were until recently relatively rare. Moreover, the share of cross-border mergers in the banking industry is low compared with other industries. This paper uses a novel dataset of over 3000 mergers that took place between 1985 and 2001 to analyze the determinants of international bank mergers. We test the extent to which information costs and regulations hold back merger activity. Our results suggest that information costs significantly impede cross-border bank mergers. Regulations also influence cross-border bank merger activity. Hence, policy makers can create environments that encourage cross-border activity, but information cost barriers must be overcome even in (legally) integrated markets.

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.
