IWH Discussion Papers,
No. 4,
2011
Abstract
Social security revenues are influenced by business cycle movements. In order to
support the working of automatic stabilizers it would be necessary to calculate social insurance contribution rates independently from the state of the business cycle. This paper investigates whether European countries set social contribution rates according to such a rule. By means of VAR estimations, country-specific effects can be analyzed – in contrast to earlier studies which used a panel design. As a result, some countries under investigation seem to vary their social contribution rates in a procyclical way.

Knowledge Sharing Through Informal Networking: An Overview and Agenda
Michael Schwartz, Christoph Hornych
International Journal of Knowledge-Based Development,
No. 3,
2011
Abstract
Informal inter-organizational networks provide manifold opportunities to organize the transfer of information, knowledge and technology between actors. The importance of informal networks as a channel of knowledge transfer is widely acknowledged by academics and practitioners. However, there is a significant lack of discussion on their theoretical foundations and systematic empirical research on the origins, dynamics and effects of informal networking. The objective of this paper is threefold. First, we review the fragmented academic discussion of the notion of informal networking, thereby focusing on how these relationships emerge initially and what conditions (presumably) are required to make them a mutually fruitful and sustainable channel of the transfer of information and knowledge. Second, we give an up-to-date overview over most important and recent studies trying to disentangle the mechanisms of inter-organizational informal networking. Finally, we outline an agenda of future research directions which we encourage researchers to pursue in future empirical studies. Overall, six important research gaps are identified.

Teil 4: Kosten der Infrastruktur: Status quo und voraussichtliche Entwicklung bis 2030
Peter Haug, Dominik Weiß
Demographischer Wandel und technische Infrastruktur: Wer soll die Kosten tragen? Eine Untersuchung am Beispiel ostdeutscher Mittelstädte,
2011
Abstract
Die berechneten Kostenszenarien für die Fallstudienstädte zeigen, dass selbst bei vollständiger Umsetzung der – aus Sicht der Kommunen – maximalen Eingriffsmöglichkeiten von den Anpassungen der technischen Netzinfrastruktur im Rahmen des Stadtumbaus bis 2030 kaum Auswirkungen auf die Durchschnittskosten dieser Infrastrukturbereiche zu erwarten sind. Viel bedeutsamer für die Kostenentwicklung sind der Einfluss unterschiedlicher Sanierungsstrategien für das bestehende Netz sowie der demographiebedingte Rückgang der Trinkwassernachfrage und damit auch des Abwasseraufkommens. Die Untersuchung belegt: Unter den gegebenen rechtlichen, politischen und gesellschaftlichen Rahmenbedingungen auf kommunaler Ebene sind die Bestandsnetze und die mit ihnen verbundenen Erhaltungs- und Finanzierungsstrategien dominant gegenüber dem Einfluss der städtebaulichen Planung.

Exchange Rate Expectations and the Pricing of Chinese Cross-listed Stocks
Stefan Eichler
Journal of Banking and Finance,
No. 2,
2011
Abstract
I show that the price discounts of Chinese cross-listed stocks (American Depositary Receipts (ADRs) and H-shares) to their underlying A-shares indicate the expected yuan/US dollar exchange rate. The forecasting models reveal that ADR and H-share discounts predict exchange rate changes more accurately than the random walk and forward exchange rates, particularly at long forecast horizons. Using panel estimations, I find that ADR and H-share investors form their exchange rate expectations according to standard exchange rate theories such as the Harrod–Balassa–Samuelson effect, the risk of competitive devaluations, relative purchasing power parity, uncovered interest rate parity, and the risk of currency crisis.

Exploring the Economic Convergence in the EU New Member States by Using Nonparametric Models
Monica Raileanu Szeles
IWH Discussion Papers,
No. 2,
2011
Abstract
This paper analyzes the process of real economic convergence in the New Member States (NMS) bein g formerly centrally planned economies, using nonparametric methods instead of conventional parametric measurement tools like beta and sigma models. This methodological framework allows the examining of the relative income distribution in different periods of time, the number of modes of the density distribution, the existence of “convergence clubs” in the distribution and the hypothesis of convergence at a single point in time. The modality tests (e.g. the ASH-WARPing procedure) and stochastic kernel are nonparametric techniques used in the empirical part of the study to examine the income distribution in the NMS area. Additionally, random effects panel regressions are used, but only for comparison reasons. The main findings of the paper are the bimodality of the income density distribution over time and across countries, and the presence of convergence clubs in the income distribution from 1995 to 2008. The findings suggest a lack of absolute convergence in the long term (1995-2008) and also when looking only from 2003 onwards. The paper concludes that, in comparison with the parametrical approach, the nonparametric one gives a deeper, real and richer perspective on the process of real convergence in the NMS area.

The Russian System of Cities from the Perspective of New Economic Geography
Albrecht Kauffmann
Potsdamer Schriften zur Raumwirtschaft, Bd. 2,
2010
Abstract
The rise in energy prices may result in long-lasting rise in costs of freight transports. Which effects do rising freight transport costs have for the development of urban systems? Such rise of transport costs in real terms has happened in Russia after price liberalisation in 1992. At the same time, the Russian official demographic statistics provides data that can be used to test hypotheses concerning the development of urban systems affected by rising transport costs. In the present study, these data are comprehensively evaluated. The theoretical background is provided by modelling of a linear shaped urban system in the framework of New Economic Geography. By means of this tool, analysis can be applied to spacious urban systems with large transport distances. For the first time, the underlying theoretical approach is explained in detail. The empirical results provide evidence for the outcomes of the theoretical model: In spacious countries or regions, respectively, whose urban systems are drawn-out on long lines, rising costs of freight transport are conducive to tendencies of concentration of population in large cities in the centre of the system, while peripheral regions are increasingly disconnected.

Deutschland im Aufschwung - Wirtschaftspolitik vor wichtigen Entscheidungen: Gemeinschaftsdiagnose Herbst 2010
Dienstleistungsauftrag des Bundesministeriums für Wirtschaft und Technologie,
2010
Abstract
Die deutsche Wirtschaft befindet sich im Aufschwung. Die Institute prognostizieren eine Zunahme des realen Bruttoinlandsprodukts um 3,5 % für das Jahr 2010 und um 2,0 % für das Jahr 2011. Die Lage am Arbeitsmarkt wird sich dabei weiter verbessern. Die Zahl der Arbeitslosen dürfte im Jahresdurchschnitt 2011 erstmals seit 1992 unter 3 Millionen liegen. Die Defizitquote des Staates dürfte auf 2,7 % sinken. Die Wirtschaftspolitik in Deutschland muss den angekündigten Konsolidierungspfad weitergehen. Auf europäischer Ebene sind Insolvenzordnungen für Staaten und Banken erforderlich. Ein strengerer Stabilitäts- und Wachstumspakt könnte als ergänzende Maßnahme sinnvoll sein. Eine Verlängerung des Rettungsschirms für Euroländer oder die Einführung von gepoolten Staatsanleihen sind dagegen genauso abzulehnen wie der von der EU-Kommission vorgeschlagene Mechanismus zur Vermeidung und Korrektur makroökonomischer Ungleichgewichte.

Informal Social Networks and Spatial Mobility
Peter Bönisch, Lutz Schneider
Post-Communist Economies,
2010
Abstract
Individuals’ preferences in transition regions are still shaped by the former communist system. We test this ‘communist legacy’ hypothesis by examining the impact of acculturation in a communist regime on social network participation and, as a consequence, on preferences for spatial mobility. We focus on the paradigmatic case of Eastern Germany, where mobility intentions seem to be substantially weaker than in the Western part. Applying an IV ordered probit approach we first find that Eastern people acculturated in a communist system are more invested in locally bounded informal social capital than Western people. Second, we confirm that membership in such locally bounded social networks reduces the intention to move away. Third, after controlling for the social network effect the mobility gap between East and West is substantially reduced. Low spatial mobility of the Eastern population, we conclude, is to an important extent attributable to a social capital endowment characteristic of post-communist economies

Incubation Time, Incubator Age, and Firm Survival after Graduation
Michael Schwartz
International Journal of Entrepreneurship and Innovation Management,
2012
Abstract
On the basis of a sample of 149 graduate firms from five German business incubators, this article contributes to incubator/incubation literature by investigating the effects of the age of the incubators and the firms´ incubation time in securing long-term survival of the firms after leaving the incubator facilities. The empirical findings from Cox proportional hazards regression and parametric accelerated failure time models reveal a statistically significant negative impact for both variables incubator age and incubation time on post-graduation firm survival. One important implication that follows from the empirical results for policy makers and managers of those initiatives is that, when incubator managers become increasingly involved in various regional development activities, this may reduce the effectiveness of incubator support. Also, our finding speaks in favour of a strict limitation of incubation times and reinforces arguments of the supporters of maximum tenancy.
