Knowledge Spill-overs for Knowledge-based Development: Progression in Theory and Obstacles for Empirical Research
Peter Franz
International Journal of Knowledge-Based Development,
2010
Abstract
As scientists and policymakers tend to interpret changes in the economy as a trend towards an increasingly knowledge-based economy, their recommendations and strategies for regional economic development frequently contain elements how to intensify the knowledge flows in the region concerned. Knowledge flows come into existence from intentional action, but also in an unintended way as externalities or knowledge spillovers. This paper reviews the ways regional and urban economics has dealt with the concept of knowledge spillovers. Knowledge spillovers are defined within a conceptual framework that points out different uses of knowledge in economics. The concept’s operationalisations in diverse empirical studies are systematised and discussed. After a critical review of the current state of research, policy strategies aiming to intensify knowledge spillovers are classified. The paper concludes with an outlook on promising new approaches to research knowledge spillovers and on the elaboration of more efficient policy strategies.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
North American Journal of Economics and Finance,
2010
Abstract
This paper evaluates the New Keynesian Phillips curve (NKPC) and its hybrid variant within a limited information framework for Germany. The main interest resides in the average frequency of price re-optimization by firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method based on the Anderson–Rubin statistic. We find that the German Phillips curve is purely forward-looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every 2–3 quarters. These estimates seem plausible from an economic point of view. But the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity, where firms never re-optimize prices. This analysis also offers some explanation as to why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way in which orthogonality conditions are formulated. Further, model mis-specifications may be left undetected by conventional J tests. This analysis points out the need for identification robust methods to get reliable estimates for the NKPC.

What Happened to the East German Housing Market? A Historical Perspective on the Role of Public Funding
Claus Michelsen, Dominik Weiß
Post-Communist Economies,
2010
Abstract
The paper analyses the development of the East German housing market after the reunification of the former German Democratic Republic and the Federal Republic of Germany in 1990. We analyse the dynamics of the East German housing market within the framework of the well-known stock-flow model, proposed by DiPasquale and Wheaton. We show that the today observable disequilibrium to a large extend is caused by post-unification housing policy and its strong fiscal incentives to invest into the housing stock. Moreover, in line with the stylized empirical facts, we show that ‘hidden reserves’ of the housing market were reactivated since the economy of East Germany became market organized. Since initial undersupply was overcome faster than politicians expected, the implemented fiscal stimuli were too strong. In contrast to the widespread opinion that outward migration caused the observable vacancies, this paper shows that not weakness of demand but supply side policies caused the observable disequilibrium.

What Determines the Innovative Success of Subsidized Collaborative R&D Projects? – Project-Level Evidence from Germany –

No. 7,

published in: Technovation
Abstract
Systemic innovation theory emphasizes that innovations are the result of an interdependent exchange process between different organizations. This is reflected in the current paradigm in European innovation policy, which aims at the support of collaborative R&D and innovation projects bringing together science and industry. Building on a large data set using project-level evidence on 406 subsidized R&D cooperation projects, the present paper provides detailed insights on the relationship between the innovative success of R&D cooperation projects and project characteristics. Patent applications and publications are used as measures for direct outcomes of R&D projects. We also differentiate between academic-industry projects and pure inter-firm projects. Main results of negative binomial regressions are that large-firm involvement is positively related to pa-tent applications, but not to publications. Conversely, university involvement has positive effects on project outcomes in terms of publications but not in terms of patent applications. In general, projects’ funding is an important predictor of innovative success of R&D cooperation projects. No significant results are found for spatial proximity among cooperation partners and for the engagement of an applied research institute. Results are discussed with respect to the design of R&D cooperation support schemes.

A First Look on the New Halle Economic Projection Model
Sebastian Giesen, Oliver Holtemöller, Juliane Scharff, Rolf Scheufele
Abstract
In this paper we develop a small open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model – the Halle Economic Projection Model (HEPM) – is closely related to studies recently published by the International
Monetary Fund (global projection model). Our main contribution is that we model the Euro area countries separately. In this version we consider Germany and France, which represent together about 50 percent of Euro area GDP. The model allows for country specific heterogeneity in the sense that we capture different adjustment patterns to economic shocks. The model is estimated using Bayesian techniques. Out-of-sample and pseudo out-of-sample forecasts are presented.

Cross-border Diversification in Bank Asset Portfolios
Claudia M. Buch, J.C. Driscoll, C. Ostergaard
International Finance,
forthcoming
Abstract
We compute optimally diversified international asset portfolios for banks located in France, Germany, Italy, the United Kingdom and the United States using the mean–variance portfolio model with currency hedging. We compare these benchmark portfolios with the actual cross-border asset positions of banks from 1995 to 2003 and ask whether the differences are best explained by regulations, institutions, cultural conditions or other financial frictions. Our results suggest that both culture and regulations affect the probability of a country's being overweighted in banks' portfolios: countries whose residents score higher on a survey measure of trust are more likely to be overweighted, while countries that have tighter capital controls are less likely to be overweighted. From a policy standpoint, the importance of culture suggests a limit to the degree of financial integration that may be achievable by the removal of formal economic barriers.

May Cities in De-Industrialized Regions Become Hot Spots for Attracting Cultural Businesses? The Case of Media Industry in Halle an der Saale (Germany)
Christoph Hornych, Martin T. W. Rosenfeld
European Planning Studies,
2010
Abstract
Policy-makers from many regions where old industrial structures in the field of manufacturing have collapsed are trying to stimulate entrepreneurial activities of businesses in the cultural industry. The question is whether this strategy could be successful. This article examines the strategy of supporting the sector of media industry (“MI”) by policy-makers in the region of Halle in East Germany, where a strong de-industrialization has taken place after the German reunification. Stimulated by the policy-makers' support measures, there actually was a remarkable development of MI. However, the number of MI firms and their employees did not further increase in recent years, after having reached a certain level. This illustrates the limits of political measures for turning a city's path of industrial development voluntarily.

Concerning the development of the debt level of the New Länder since the German unification

Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 2 -
2010
Abstract
Die öffentliche Verschuldung ist deutschlandweit seit den 1990er Jahren deutlich angestiegen. Besonders stark fällt der Zuwachs in den Neuen Ländern aus. Diese waren durch die Bündelung der DDR-Altschulden im Kreditabwicklungsfonds nach der Deutschen Einheit fast schuldenfrei. Heute, 20 Jahre später, weisen einzelne Neue Länder einen Schuldenstand aus, der über dem Durchschnittswert aller Bundesländer liegt. Die Hintergründe für diese Entwicklung sind komplex und teilweise auch der individuellen Situation der einzelnen Länder geschuldet. Allgemein kann die stark angestiegene Verschuldung der Neuen Flächenländer in den 1990er Jahren auf die – aus heutiger Sicht – zu optimistische Einschätzung der Angleichung der Wirtschafts- und Finanzkraft der Neuen an die Alten Länder zurückgeführt werden. Darüber hinaus waren die Neuen Flächenländer un-terschiedlich stark vom transformationsbedingten strukturellen Umbruch und den daraus resultierenden Schwierigkeiten bei der Marktanpassung betroffen.
In Sachsen-Anhalt, das die höchsten Verschuldungskennzahlen der Neuen Länder aufweist, führte beispielsweise der Zusammenbruch der Grundstoffindustrie zu einer überdurchschnittlich hohen regionalen Arbeitslosigkeit und zu einer massiven Abwanderung der Bevölkerung. Noch immer hat Sachsen-Anhalt bundesweit den größten negativen Wanderungssaldo. Die Verschuldung des Landes, beispielsweise gemessen am Schuldenstand je Einwohner, steigt somit allein schon durch den Bevölkerungsverlust.
Ungeachtet dieser landesspezifischen Besonderheiten des Transformationsprozesses hat um die Jahrtausendwende bei allen Neuen Ländern eine schrittweise Veränderung in der Einstellung und im Umgang mit den vorhandenen Schulden eingesetzt. Die Haushaltskonsolidierung gewinnt zunehmend an Bedeutung. Ihre Umsetzung wurde außerdem durch den konjunkturellen Aufschwung der Jahre 2006 und 2007 unterstützt. Gegenwärtig werden die Konsolidierungsbemühungen der Länder allerdings durch die Wirtschaftskrise auf die Probe gestellt.

Characteristics of Business Cycles: Have they Changed?
Oliver Holtemöller, J. Rahn, M. H. Stierle
IWH-Sonderhefte,
No. 5,
2009
Abstract
The most recent economic downturn has shown that economic activity nowadays is still prone to large fluctuations. Despite a long tradition of research, the understanding of such fluctuations, namely business cycles, is still far from comprehensive. Moreover, in a developing world with new technologies, faster communication systems, a higher integration of world markets and increasingly better-skilled people the nature of business cycles changes continuously and new insights can be drawn from recent experience.
