Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems

Determinants of Innovative Behaviour,
2008
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of 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 that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, 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 explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
No. 58,
2008
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Wirtschaft im Wandel,
No. 2,
2008
Abstract
Die Wirtschaftstheorie hat die räumliche Dimension des Wirtschaftens lange Zeit vernachlässigt. Spätestens durch die Ansätze der New Economic Geography hat sich in den Wirtschaftswissenschaften mittlerweile aber allgemein die Erkenntnis durchgesetzt, daß räumliche Nähe bzw. Ferne wichtige Faktoren für die Erklärung wirtschaftlicher Entwicklungsprozesse sind. Leider hat sich eine entsprechende Auffassung in der Politik bislang nur rudimentär verbreiten können. So werden wirtschafts- und finanzpolitische Entscheidungen nach wie vor zumeist ohne Beachtung ihrer räumlichen Konsequenzen diskutiert bzw. getroffen.

New Limits of Municipal Economic Activity: Expansion versus Reduction?
Peter Haug
Wirtschaft im Wandel,
No. 12,
2007
Abstract
Das IWH veranstaltete unter Federführung der Abteilung Stadtökonomik am 11. und 12. Oktober 2007 zum zweiten Mal eine Tagung mit dem Themenschwerpunkt Kommunalwirtschaft. Das zentrale Anliegen der Veranstaltung war es, im Rahmen eines interdisziplinären Dialogs die räumlichen wie sachlichen Grenzen kommunaler Wirtschaftstätigkeit auszuloten. Das Kolloquium richtete sich dabei sowohl an einschlägig tätige Wissenschaftler als auch an Praktiker der Kommunalwirtschaft und -verwaltung, Verbandsvertreter, Politiker und andere Interessierte. Die Beiträge behandelten ein breites Themenspektrum. Ein Themenblock des ersten Konferenztags befaßte sich mit der teilweise kontroversen Bewertung der kommunalwirtschaftlichen Tätigkeit aus Sicht verschiedener Fachdisziplinen: Rechtswissenschaft, Volkswirtschaftslehre, öffentliche Betriebswirtschaftslehre und Soziologie. Daneben wurden ausgewählte Einzelbereiche der kommunalen Wirtschaftstätigkeit (ÖPNV, kommunale Wohnungswirtschaft) vertieft behandelt. Der zweite Konferenztag war den Themen Grenzen der Kommunalwirtschaft in Südeuropa, regionalwirtschaftliche Effekte kommunaler Wirtschaftstätigkeit und der Frage des Arbeitnehmerschutzes bei Privatisierungen gewidmet. Eine Podiumsdiskussion mit Vertretern aus Politik, Wissenschaft und Wirtschaft zur zukünftigen Bedeutung städtischer Firmen für die Finanz-, Wirtschafts- und Gesellschaftspolitik schloß die Veranstaltung ab. Als Resümee der Veranstaltung läßt sich ziehen, daß im kommunalen Sektor vieles in Bewegung ist, unter anderem aufgrund zunehmenden EU-Integration und der Liberalisierung des Energiesektors. Darüber hinaus wurde einer schrankenlosen räumlichen wie sachlichen Ausweitung der kommunalen Wirtschaftstätigkeit genauso eine Absage erteilt wie einer vollständigen Privatisierung der Kommunalwirtschaft.

The Economic Geography of Offshoring.
Ulrich Blum
Offshoring Journal,
No. 1,
2007
Abstract
Der Begriff Offshoring bezeichnet die (zumindest teilweise) Geschäftsverlagung nach Übersee bzw. den Einkauf ehemals unternehmenseigener Dienstleistungen aus Entwicklungsländern. Heute sind Offshoring-Aktivitäten vor allem bei Dienstleitungen interessant, welche digitale Verarbeitungsprozesse beinhalten. Auch Unternehmensleistungen mit niedrigen Transaktionskosten bzw. Aktivitäten wo andere Länder Standortvorteile aufweisen eignen sich für Offshoring. Allerdings sind die Möglichkeiten des Offshoring auch immer individuell vom Unternehmen selbst sowie vom entsprechenden Rechtssystem des Landes abhängig.

FDI versus exports: Evidence from German banks
Claudia M. Buch, A. Lipponer
Journal of Banking and Finance,
No. 3,
2007
Abstract
We use a new bank-level dataset to study the FDI-versus-exports decision for German banks. We extend the literature on multinational firms in two directions. First, we simultaneously study FDI and the export of cross-border financial services. Second, we test recent theories on multinational firms which show the importance of firm heterogeneity [Helpman, E., Melitz, M.J., Yeaple, S.R., 2004. Export versus FDI. American Economic Review 94 (1), 300–316]. Our results show that FDI and cross-border services are complements rather than substitutes. Heterogeneity of banks has a significant impact on the internationalization decision. More profitable and larger banks are more likely to expand internationally than smaller banks. They have more extensive foreign activities, and they are more likely to engage in FDI in addition to cross-border financial services.

Where enterprises lead, people follow? Links between migration and FDI in Germany
Claudia M. Buch, J. Kleinert, Farid Toubal
European Economic Review,
No. 8,
2006
Abstract
Standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter. Yet, these two assumptions are violated if agglomeration forces among factors from specific source countries are at work. Agglomeration implies that factors behave as complements and that the country of origin matters. This paper analyzes agglomeration between capital and labor empirically. We use state-level German data to answer the question whether and how migration and foreign direct investment (FDI) are linked. Stocks of inward FDI and of immigrants have similar determinants, and the geography of factor market integration matters. There are higher stocks of inward FDI in German states hosting a large foreign population from the same country of origin. This agglomeration effect is confined to higher-income source countries.
