International Journal of Networking and Virtual Organisations,
Nr. 4,
2013
Abstract
Wissensintensive Interaktionen sind mit einer Reihe von Vor- und Nachteilen für die beteiligten Akteure verbunden. Deshalb hat sich ein Literaturstrang entwickelt, welcher der Fragestellung nachgeht, wie sich FuE-Kooperationen auf die Leistungsfähigkeit von Firmen und Regionen auswirken. Diese Studien kommen zu unterschiedlichen Ergebnissen. Das Papier versucht die verschiedenen Ergebnisse der Literatur zusammenzufassen. Ein weiteres Ziel ist es, die in der Literatur verwendeten Methoden zur Bearbeitung der Fragestellung kritisch zu diskutieren. Zudem geht das Papier der Frage nach, inwiefern die in der Literatur verwendeten Methoden und Ansätze die Ergebnisse der Studien beeinflussen. Zur Bearbeitung dieser Fragestellungen wird eine Metaanalyse der relevanten Literatur durchgeführt. Dabei wird gezeigt, dass FuE-Kooperationen einen positiven Effekt auf die Leistungsfähigkeit von Firmen und Regionen haben. Zudem gibt es starke Evidenz dafür, dass die verwendeten Methoden und Ansätze die Ergebnisse der Studien beeinflussen.

Regions as Selection Environments? The Emergence of the Solar Industry in Germany from 1992 to 2008
Matthias Brachert, Christoph Hornych, Peter Franz
European Planning Studies,
Nr. 11,
2013
Abstract
The spatial evolution of the German solar industry is analysed in the light of the “window of locational opportunity” and the “selection environment” approach. The paper argues that differences in the regions' ability to promote the emergence of local external economies contribute to increasing regional differentiation in the German structure of the industry. Applied empirical methods enclose longitudinal firm entry and network analysis. A special focus is given upon the realignment processes in the science system. Our findings show a relatively rapid spatial concentration of production in eastern Germany since the year 2000. This process is accompanied by intensified networking between firms and between firms and universities as well as research institutes. The responsiveness of regional institutions and the self-organizing capabilities of the solar firms substantiate some propositions of the “selection environment” approach.

FDI Micro Database – Methodological Note – Survey 2012 in East Germany
Jutta Günther, Andrea Gauselmann, Björn Jindra, Philipp Marek, Jan Engelhardt
Einzelveröffentlichungen,
2012
Abstract
With the integration of post-communist countries into the European and global economy
after 1990, there was strong research interest into the role of multinational enterprises
(MNEs) for economic restructuring and technological catching-up. Most of the existing
empirical studies on locational determinants of FDI and host country effects did not take
account of East Germany. This might be for different reasons: Firstly, theoretical and
empirical difficulties derive from the fact that East Germany followed a distinct transition
pattern as it became a region subsumed in a larger and more mature economy. Secondly,
East Germany received private investment from foreign as well as West German firms. Only
the first can be considered as a foreign direct investment (FDI). Finally, there had long been
a lack of micro data to adequately analyse the activities of corresponding firms from a
production as well as technological perspective.

Women Move Differently: Job Separations and Gender
Boris Hirsch, Claus Schnabel
Journal of Labor Research,
Nr. 4,
2012
Abstract
Using a large German linked employer–employee data set and methods of competing risks analysis, this paper investigates gender differences in job separation rates to employment and nonemployment. In line with descriptive evidence, we find lower job-to-job and higher job-to-nonemployment transition probabilities for women than men when controlling for individual and workplace characteristics and unobserved plant heterogeneity. These differences vanish once we allow these characteristics to affect separations differently by gender. When additionally controlling for wages, we find that both separation rates are considerably lower and also significantly less wage-elastic for women than for men, suggesting an interplay of gender differences in transition behaviour and the gender pay gap.

Methodik und Probleme regionaler ökonomischer Projektionen
Maike Irrek, Oliver Holtemöller
Flächennutzungsmonitoring IV. Genauere Daten – informierte Akteure – praktisches Handeln. IÖR-Schriften 60,
2012
Abstract
Regionale ökonomische Projektionen sind wichtig für die politische Entscheidungsfindung in vielen Bereichen, so auch bei der Flächennutzung. Sowohl wohnbauliche als auch gewerbliche Flächennutzungen werden vom regionalen Wirtschaftswachstum beeinflusst. In diesem Beitrag werden die Methodik und die Probleme von regionalen Wirtschaftsprojektionen am Beispiel eines mittel- und langfristigen Projektionsmodells der gesamtwirtschaftlichen Entwicklung in Deutschland und in den Ländern dargestellt. Das Modell verwendet den Produktionsfunktionsansatz, für welchen die Produktionsfaktoren Arbeit und Kapital sowie die Produktivität mit Hilfe zeitreihenökonometrischer Methoden fortgeschrieben werden. Die Ergebnisse für Deutschland insgesamt zeigen, dass das Bruttoinlandsprodukt im Zeitraum von 2011 bis 2025 trotz des demographisch bedingten Rückganges des Arbeitsvolumens weiter wachsen dürfte. Die unterschiedliche Ausprägung des demographischen Wandels in den Ländern wird allerdings zu regionalen Wachstumsunterschieden führen. Dies wird beispielhaft anhand eines Vergleichs von Sachsen und Baden-Württemberg dargestellt.

Qual VAR Revisited: Good Forecast, Bad Story
Makram El-Shagi, Gregor von Schweinitz
Abstract
Due to the recent financial crisis, the interest in econometric models that allow to incorporate binary variables (such as the occurrence of a crisis) experienced a huge surge. This paper evaluates the performance of the Qual VAR, i.e. a VAR model including a latent variable that governs the behavior of an observable binary variable. While we find that the Qual VAR performs reasonably well in forecasting (outperforming a probit benchmark), there are substantial identification problems. Therefore, when the economic interpretation of the dynamic behavior of the latent variable and the chain of causality matter, the Qual VAR is inadvisable.

Bottom-up or Direct? Forecasting German GDP in a Data-rich Environment
Katja Drechsel, Rolf Scheufele
Abstract
This paper presents a method to conduct early estimates of GDP growth in Germany. We employ MIDAS regressions to circumvent the mixed frequency problem and use pooling techniques to summarize efficiently the information content of the various indicators. More specifically, we investigate whether it is better to disaggregate GDP (either via total value added of each sector or by the expenditure side) or whether a direct approach is more appropriate when it comes to forecasting GDP growth. Our approach combines a large set of monthly and quarterly coincident and leading indicators and takes into account the respective publication delay.

Delineation of City Regions Based on Commuting Interrelations: The Example of Large Cities in Germany
Albrecht Kauffmann
IWH Discussion Papers,
Nr. 4,
2012
Abstract
The comparison of cities with regard to their economic or demographic development may yield misleading results, if solely the cities in their administrative borders are the object of consideration. Frequently, historical borders of cities neither conform to the contemporary settlement structures, nor do they consider the mutual dependencies between cities and parts of their hinterland. Therefore, it is often claimed to use city regions as objects of comparison or for the sake of urban planning. Commonly, the delineation of functional regions is based on commuting flows from the municipalities in the hinterland of the core cities directed to the cores. A municipality is regarded as belonging to a certain city region if the share of out-commuters from this municipality to the respective core in the total mass of those employees who reside in that municipality is the largest one, and if this share exceeds a certain threshold value. However, commuting flows in the opposite direction are not considered. The method presented here delineates city regions on the base of bidirectional commuting flows. Hereby, various modifications regarding the characteristics of the employment base, the possibility of overlaps of regions, the formation of polycentric city regions, and of the minimum threshold value of mutual connectivity are applied to the sample of 81 German cities with more than 100 000 inhabitants. Finally, the effects of different kinds of regionalisation on the coefficients of regional specialisation of these cities and city regions are demonstrated.
