Abstract
Eine starke Verbundenheit von Wirtschaftszweigen wirkt positiv auf das regionale Beschäftigungswachstum – allerdings nur dann, wenn zugleich Führungskräfte in der Region überdurchschnittlich präsent sind. Fehlt das Zusammenspiel von Verbundenheit und Führungsfunktionen – etwa bei einem Mangel an Unternehmens-Headquartern in der Region –, wirkt dies negativ auf das Beschäftigungswachstum.

Related Variety, Unrelated Variety and Regional Functions: Identifying Sources of Regional Employment Growth in Germany from 2003 to 2008
Matthias Brachert, Alexander Kubis, Mirko Titze
Abstract
This article analyses how regional employment growth in Germany is affected by related variety, unrelated variety and the functions a region performs in the production process. Following the related variety literature, we argue that regions benefit from the existence of related activities that facilitate economic development. However, we argue that the sole reliance of related variety on standard industrial classifications remains debatable. Hence, we offer estimations for establishing that conceptual progress can indeed be made when a focus for analysis goes beyond solely considering industries. We develop an industry-function based approach of related and unrelated variety. Our findings suggest that related variety only in combination with a high functional specialization of the region facilitates regional growth in Germany. Additionally, also unrelated variety per se fails to wield influences affecting development of regions. It is rather unrelated, but functionally proximate variety in the groups “White Collar” and “Blue Collar Workers” positively affects regional employment growth.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Annals of Regional Science,
No. 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.

Monopolistic Competition and Costs in the Health Care Sector

IWH Discussion Papers,
No. 17,
2009
Abstract
Competition among health insurers is widely considered to be a means of enhancing efficiency and containing costs in the health care system. In this paper, it is argued that this could be unsuccessful since health care providers hold a strong position on the market for health care services. Physicians exert a type of monopolistic power which can be described by Chamberlin’s model of monopolistic competition. If many health insurers compete with one another, they cannot counterbalance the strong bargaining position of the physicians. Thus, health care expenditure is higher, financing either extra profits for physicians or a higher number of them. In addition, health insurers do not have an incentive to contract selectively with health care providers as long as there are no price differences between physicians. A monopolistic health insurer is able to counterbalance the strong position of physicians and to achieve lower costs.

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.

Grenzen des Wettbewerbs im Gesundheitswesen
Ingmar Kumpmann
IWH Discussion Papers,
No. 1,
2008
Abstract
Viele Gesundheitsökonomen fordern mehr Wettbewerb im Gesundheitswesen. Damit ist ein stärkerer Wettbewerb zwischen Krankenkassen um Versicherte und zwischen Leistungserbringern um Verträge mit Kassen gemeint. Vernachlässigt wird dabei jedoch der für die medizinische Qualität wichtige Wettbewerb der Leistungserbringer um Patienten. Dieser steht mit den beiden zuerst genannten Wettbewerbsfeldern im Konflikt. Auch die vorhandene empirische Evidenz ist uneindeutig was die Kosten- und Qualitätseffekte des Wettbewerbs im Gesundheitswesen betrifft. Die einfache Forderung nach „mehr Wettbewerb“ wird somit der Komplexität des Gesundheitswesens nicht gerecht.

„Where Have All the Young Girls Gone …?” Regional Analysis of Young Women’s Migration Behavior
Alexander Kubis, Lutz Schneider
Wirtschaft im Wandel,
No. 8,
2007
Abstract
Der vorliegende Beitrag untersucht die Muster sowie die Determinanten des Wanderungsverhaltens junger Frauen im Alter zwischen 18 und 30 Jahren. Auf NUTS-3-Ebene, d.h. der Ebene der Kreise, werden die Ströme der gesamtdeutschen Binnenwanderung des Jahres 2005 analysiert. Es zeigt sich, daß die Regionen mit einem ausgesprochen negativen Wanderungssaldo junger Frauen in der ostdeutschen Peripherie zu finden sind, während die westdeutschen Agglomerationen, aber auch die großen Städte in den Neuen Bundesländern von Zuzügen dieser Gruppe profitieren. Die Analyse der Bestimmgründe der regionalen Wanderungsströme junger Frauen belegt die Signifikanz der ökonomischen, familien- und bildungsbezogenen Wanderungsmotive. Im allgemeinen wandern junge Frauen in Regionen mit guten Einkommens- und hochwertigen Erwerbsmöglichkeiten, wobei die Vereinbarkeit von Familie, Partnerschaft und Beruf im genuinen Interesse dieser Gruppe zu liegen scheint. Ferner zeigt sich eine ausgeprägte Anziehungskraft von Regionen mit erstrangigen Bildungsangeboten. Dabei generiert diese Bildungswanderung nicht nur einen kurzfristigen, sondern nachhaltig positiven Effekt auf die regionale Wanderungsbilanz. Dies gilt vornehmlich für Regionen, in denen nicht nur Studienplätze vorhanden sind, sondern ebenso Arbeitsfelder für hochqualifizierte Hochschulabsolventinnen. Mit Blick auf mögliche Handlungsoptionen angesichts ausgeprägter regionaler Wanderungsverluste belegt die vorliegende Studie erstens die Bedeutung von Maßnahmen der Wirtschaftsförderung, sofern diese der Verbesserung der regionalen Erwerbs- und Einkommenschancen dienen. Zweitens scheint der Ausbau frauenspezifischer Bildungsangebote ein geeignetes Mittel zu sein, um die Anziehungskraft einer Region für junge Frauen nachhaltig zu erhöhen. Drittens deuten die Ergebnisse darauf hin, daß die Vereinbarkeit von Familie und Beruf eine Stellschraube darstellt, welche die Zuwanderung junger Frauen stimulieren kann.

What Determines the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2007-006,
No. 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.
