Arbeitsmarktbilanz Ostdeutschland: Bedeutung sozialversicherungspflichtiger Beschäftigung nimmt zu
Hans-Ulrich Brautzsch

Nr. 11,
2011
Abstract
Die Lage auf dem ostdeutschen Arbeitsmarkt hat sich weiter verbessert. Vom gesamten Beschäftigungsaufbau entfällt etwa die Hälfte auf das Produzierende Gewerbe. Der Rückgang der Zahl der Arbeitslosen war allerdings
trotz der anhaltenden Schrumpfung des Arbeitsangebots geringer als der Beschäftigungsaufbau. Hierfür waren Sonderfaktoren verantwortlich, beispielsweise der Wegfall der Freizügigkeitsbeschränkung für Arbeitnehmer
aus den neuen Mitgliedstaaten der Europäischen Union und die Rückführung arbeitsmarktpolitischer Maßnahmen. Im weiteren Verlauf dieses Jahres wird sich trotz der schwachen Ausdehnung der gesamtwirtschaftlichen Produktion die Lage auf dem ostdeutschen Arbeitsmarkt noch leicht verbessern. Die Zahl der Erwerbstätigen wird im Durchschnitt des Jahres 2011 um 67 000 Personen bzw. 1,2% über dem Vorjahreswert liegen. Im kommenden Jahr werden in etwa so viele Personen erwerbstätig sein wie in diesem Jahr. Der Anteil der sozialversicherungspflichtig Beschäftigten an der Zahl der Erwerbstätigen wird hingegen weiter zunehmen. Die Entwicklung der Zahl der registrierten Arbeitslosen wird auch im Prognosezeitraum bis 2012 erheblich vom schrumpfenden Arbeitsangebot beeinflusst. Die Arbeitslosenquote wird in diesem Jahr 11,0% und im kommenden Jahr 10,9% betragen.

Determinants of the Efficiency of Regional Innovation Systems

Regional Studies,
Nr. 7,
2011
Abstract
Determinanten der technischen Effizienz von regionalen Innovationssystemen, Regional Studies. Wir analysieren Unterschiede in der Effizienz regionaler Innovationssysteme (RIS). Zunächst werden alternative Maße für die Effizienz von RIS diskutiert, die auf dem Konzept der Wissensproduktionsfunktion aufbauen. Die empirischen Ergebnisse deuten darauf hin, dass sowohl Spillover aus dem privaten Sektor als auch von Hochschulen und anderen öffentlichen Forschungseinrichtungen die Effizienz privater F&E-Aktivitäten positiv beeinflussen. Insbesondere die Intensität der Interaktion zwischen öffentlichen Einrichtungen und dem Privatsektor führt zu hoher Effizienz. Regionen, die durch Großbetriebe dominiert sind, weisen tendenziell eine geringere Effizienz der Innovationsaktivitäten auf als Regionen mit einer geringeren durchschnittlichen Betriebsgröße.

Fiscal Spending Multiplier Calculations based on Input-Output Tables – with an Application to EU Members
Toralf Pusch, A. Rannberg
Abstract
Fiscal spending multiplier calculations have been revived in the aftermath of the
global financial crisis. Much of the current literature is based on VAR estimation
methods and DSGE models. The aim of this paper is not a further deepening of
this literature but rather to implement a calculation method of multipliers which is
suitable for open economies like EU member states. To this end, Input-Output tables are used as by this means the import intake of domestic demand components can be isolated in order to get an appropriate base for the calculation of the relevant import quotas. The difference of this method is substantial – on average the calculated multipliers are 15% higher than the conventional GDP fiscal spending multiplier for EU members. Multipliers for specific spending categories are comparably high, ranging between 1.4 and 1.8 for many members of the EU. GDP drops due to budget consolidation might therefore be substantial if monetary policy is not able to react in an expansionary manner.

Regional Entrepreneurial Opportunities in the Biotech Industry: Exploring the Transition from Award-winning Nascent Entrepreneurs to Real Start-ups
H. Wolf, Claus Michelsen, Michael Schwartz
Abstract
Knowledge of factors that determine the transition from nascent entrepreneurship into real entrepreneurship is of major importance for policies aiming to effectively stimulate start-ups. Whereas scholars concentrated on person-specific factors to explain transition probabilities, environmental characteristics have been fairly neglected. Given that entrepreneurship is a strongly localized phenomenon, this paper argues that regional entrepreneurial opportunities are a driving force behind the transition from nascent entrepreneurship to new venture creation. Based on unique data on 103 nascent entrepreneurs in the German biotechnology industry, we empirically assess the importance of regional entrepreneurial opportunities on transition probabilities. Further, we introduce a new
approach to measure nascent entrepreneurship by capturing individuals that actively participate in start-up competitions and have won at least one competition. Controlling for technology and individual characteristics, we find strong support for our hypotheses relating to the significant impact of general regional opportunities, specific regional opportunities and the entrepreneurial environment for the probability of transition from award-winning nascent entrepreneurs to real start-ups.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Annals of Regional Science,
Nr. 1,
2010
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 externalities resulting from high R&D intensity of the local private sector as well as knowledge from local public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Metformin-Therapie bei PCO-Syndrom - Positive Vierjahresbilanz des oralen Antidiabetikums
D. Albrecht, P. Kaltwasser, E. Rosenkranz, Dirk Trocka
MedReview,
2007
Abstract
Das Polyzystische Ovarialsyndrom (PCOS) ist mit einer Krankheitshäufigkeit von 4–12 % die häufigste endokrine Erkrankung der Frau im reproduktiven Alter. Neben dem unerfüllten Kinderwunsch stellt es ein hohes Risiko für metabolische (stoffwechselbedingte) und kardiovaskuläre (Herz und Blutgefäße betreffende) Erkrankungen dar. Die Studie stellt die ersten Ergebnisse der Behandlung des PCOS mit dem oralen Antidiabetikum Metformin in einer Vierjahres-Analyse dar und versucht Kriterien für den Einsatz des Arzneistoffes zu definieren.

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.

What Determines the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2007-006,
Nr. 6,
2007
Abstract
We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region. Different measures and estimation approaches lead to rather similar assessments. We find that both spillovers within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector R&D in the respective region. It is not the mere presence and size of public research institutions, but rather the intensity of interactions between private and public sector R&D that leads to high RIS efficiency. We find that relationship between the diversity of a regions’ industry structure and the efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.
