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.

Abstract
The Volume XIV analyses the “New Growth and Poverty Alleviation Strategies for Africa“. Institutional issues and perspectives in designing new growth and poverty alleviation strategies are considered in various case studies (Cote d'Ivoire, Nigeria, Botswana and Tanzania). Other studies deal with institutional problems of resource-rich countries after conflict (Sudan) and with the institutions to enhance environmental protection parallel to economic growth and poverty reduction (Niger). Further studies deal with institutions to bridge the gap between formal and informal entrepreneurial sectors in Kenya and Tanzania. Local issues and perspectives for designing new growth and poverty alleviation strategies are considered in case studies on rural-urban development gaps in Tanzania and on microfinance as an instrument for new growth and poverty alleviation strategies (Tanzania and Eritrea). A study on small farmers in Ghana provides information on the role they can play in value chains. Two studies on Nigeria highlight the local and the sub-regional health and poverty alleviation programmes and the relation to growth. Book reviews and book notes on the theme are part of the volume. This volume builds the foundation for a comprehensive strategy of policy reforms in Africa so as to integrate new growth and poverty alleviation strategies. Complementary to Volume XIV is Volume XIII on “New Growth and Poverty Alleviation Strategies for Africa - Interational and Regional Perspectives“. Both volumes are of importance for all those who work in African countries as officials, executives, managers, researchers, and policy-makers, but also for all those who actively support Africa's development concerns at the international, regional, country, local, and project levels. They will experience this Volume XIV and also the complementary Volume XIII as indispensable sources of insight, reference, and inspiration.

The Economic Optimality of Sanction Mechanisms in Interorganizational Ego Networks – A Game Theoretical Analysis –
Muhamed Kudic, Marc Banaszak
IWH Discussion Papers,
No. 15,
2009
Abstract
Even though small- and medium-sized firms (SMEs) were believed not to proceed beyond exporting in their internationalization routes, we can observe new types of co-operation intensive entrepreneurial firms – so-called “micromultinational enterprises” (mMNEs) – entering the global landscape. These firms face the challenge to manage and control a portfolio of national and international alliances simultaneously (ego network). The aim of this paper is to provide game theoretically consolidated conditions in order to analyze the effectiveness and efficiency of interorganizational sanction mechanisms in an alliance portfolio setting. A game theoretical framework is developed over three stages with increasing complexity. Results show that two out of six analyzed sanction mechanisms do not fulfill the game theoretical condition for effectiveness. The efficiency analysis sensibilizes for discretionary elements in governance structures and demonstrates that not one single sanction mechanism but rather the right choice and combination of different types of sanction mechanisms leads to efficient results. We contribute to the international business, alliance, and network literature in several ways by focusing on alliance portfolios held by mMNEs. In doing so, we move beyond the dyadic level and analyze sanction mechanisms from an ego network perspective, a still widely under-emphasized topic in the literature.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
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.
