This dissertation applies the theory of technology accumulation to explain the internationalisation of foreign and West German multinational enterprises (MNEs) into East Germany. This theory shifts the focus from technology transfer to the international diffusion of innovation within the MNE. It rejects the position that all MNEs offer the same technological opportunities to host economies. Yet, most of the existing empirical research on postcommunist transition economies including East Germany applies the traditional technology transfer perspective. Therefore, this dissertation provides a complementary and novel approach. We assume a dynamic interaction between existing location specific technological capabilities within the host country, MNEs’ location choice, their internationalisation of research and development (R&D) and innovation, and the potential for technological spillover effects from MNEs to the host economy. The dissertation exploits information from the IWH FDI micro database on the full population of MNEs that entered East German manufacturing until 2005 and corresponding survey data. Microeconometric estimation results generate a number of novel findings: We can show that existing location specific technological capabilities affect MNEs’ general location choice within East Germany. They are not powerful enough to attract MNEs’ technological activities. Instead, the location of MNEs’ innovation requires the joint presence of technological and industry specialisation within regions, whereas foreign R&D benefits from technological specialisation in combination with a diversified industry structure. Moreover, the location of technological activity differs depending upon the underlying motive for internationalisation. Our findings suggest that the potential for technological externalities from affiliates to local firms is subject to centrally and locally driven technological heterogeneity of MNEs. Existing location specific technological capabilities do not affect the spillover potential. This hints a limited dynamic interaction of ownership and locational advantages in firms’ internationalisation. We derive implications for the technology accumulation theory as well as for various fields of science and technology policy.

The study contributes to the development of ’standards’ for the application of matching algorithms in empirical evaluation studies. The focus is on the first step of the matching procedure, the choice of an appropriate distance function. Supplementary o most former studies, the simulation is strongly based on empirical evaluation ituations. This reality orientation induces the focus on small samples. Furthermore, ariables with different scale levels must be considered explicitly in the matching rocess. The choice of the analysed distance functions is determined by the results of former theoretical studies and recommendations in the empirical literature. Thus, in the simulation, two balancing scores (the propensity score and the index score) and the Mahalanobis distance are considered. Additionally, aggregated statistical distance functions not yet used for empirical evaluation are included. The matching outcomes are compared using non-parametrical scale-specific tests for identical distributions of the characteristics in the treatment and the control groups. The simulation results show that, in small samples, aggregated statistical distance functions are the better

choice for summarising similarities in differently scaled variables compared to the

commonly used measures.

The aim of this paper is to analyze whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics, and thus, to identify an unbiased effect of the public support. Besides the ‘total effect’ of support, it is of special interest if the effect is stronger for subsidized youths in external training compared to persons in workplace-related training. The analysis is based on unique and very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).

The results show that young people who successfully completed a subsidized vocational education are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences on the employment prospects. Besides a quantitative effect, the analysis shows that the graduates of subsidized training work in slightly worse (underqualified) and worse paid jobs than the adolescents in the reference group. The comparison of both types of subsidized vocational training, however, does not confirm the expected stronger effect for youths in external vocational education compared to workplace-related training.

Degree-level science and engineering skills as well as management and leadership skills are often referred to as a source of innovative activities within companies. Broken down by sectoral innovation patterns, this article examines the role of formal education and actual occupation for product innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain detailed information about innovative activities and the qualification of employees. We find significant differences of the human capital endowment between sectors differentiated according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in product innovation above average (specialized suppliers and science based industries). According to our hitherto estimation results, within these sectors the share of highly skilled employees does not, however, substantially increase the probability to be an innovative firm.

Die Anwendung von Evaluationsverfahren zur Beurteilung unterschiedlicher Handlungsalternativen gewinnt in verschiedenen Forschungsfeldern zunehmend an Bedeutung. Von den zur Lösung des dabei auftretenden Selektionsproblems entwickelten Verfahren haben insbesondere die nichtparametrischen große Bedeutung in der empirischen Anwendung erlangt. In diesem Beitrag wird ein Überblick über diese Verfahren gegeben, wobei die bisher bestehende Lücke zwischen einführenden Texten und der weiterführenden, eher formalen Literatur geschlossen werden soll. Dazu werden die Vor- und Nachteile der Verfahren, die nötigen Annahmen sowie die Anforderungen an die Datenbasis erläutert. Aus der Darstellung wird ersichtlich, dass für die empirische Anwendung keine Methode zur Lösung des Selektionsproblems den anderen generell überlegen ist. Alle Ansätze beruhen auf bestimmten Grundannahmen, und jeder Schätzer ist verzerrt, wenn die zur Verfügung stehende Datenbasis nicht zu diesen Annahmen passt.

The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.

Die Evaluation der ökonomischen Wirkungen von betrieblicher Mitbestimmung ist aufgrund von spezifischen Merkmalen bei Betrieben mit Betriebsräten aus methodischer Sicht nicht unproblematisch. So führen bisherige Studien zu teilweise konträren Ergebnissen. In der hier vorliegenden Studie sollen daher die Probleme aufgezeigt, näher diskutiert und Lösungsmöglichkeiten an dem Beispiel der betrieblichen Mitbestimmung in ostdeutschen Betrieben des produzierenden Gewerbes und des Baus dargestellt werden. Es wird ein optimaler Matching-Algorithmus zur Zuordnung von „statistischen Zwillingsbetrieben“ genutzt, der insbesondere gute Matchingergebnisse bei geringen Fallzahlen liefert. Da mit der ursprünglichen Teilnehmergruppe aufgrund kurzer Beobachtungsperioden nur kurzfristige Effekte ermittelt werden können, wird das Matchingverfahren zusätzlich zur Konstruktion verlängerter Beobachtungsperioden genutzt. Bei diesem neuen Anwendungsfall werden Betriebe, die einen Betriebsrat gegründet haben mit sogenannten Stellvertreter-Betrieben, die bereits einen Betriebsrat besitzen, verknüpft. Dadurch werden die kurzen Beobachtungsdauern verlängert, und es können auch Aussagen über die längerfristige Wirkung der betrieblichen Mitbestimmung getroffen werden. Die ermittelten Effekte auf die Produktivität, die Ertragslage und das Qualifikationsniveau der Beschäftigten deuten weder kurz- noch langfristig auf eine signifikante Wirkung der betrieblichen Mitbestimmung hin.

This study deals with the effect of fixed-term contracts on work-related training. Though previous studies found a negative effect of fixed-term contracts on the participation in training, from the theoretical point of view it is not clear whether workers with fixed-term contracts receive less or more training, compared to workers with permanent contracts. In addition to the existing strand of literature, we especially distinguish between employer- and employee-financed training in order to allow for diverging investment patterns of worker and firm. Using data from the German Socio-Economic Panel (GSOEP), we estimate a bivariate probit model to control for selection effects that may arise from unobservable factors, affecting both participation in training and holding fixed-term contracts. Finding negative effects for employer-sponsored, as well as for employee-sponsored training, leads us to conclude that workers with fixed-term contracts do not compensate for lower firm investments.

In der wirtschaftswissenschaftlichen Diskussion wird die hohe Zahl von Sozialhilfe­empfängern vor allem damit begründet, dass der Lohnabstand zwischen Erwerbstätigkeit und Sozialhilfe zu gering sei. Folglich lohne es sich nicht zu arbeiten. Eine statistische Absicherung dieser Aussage fehlt jedoch ebenso wie die Einbeziehung alternativer Anreizfaktoren in eine multiple Analyse. Darüber hinaus kann das Argument nicht erklären, warum ein hoher Anteil derjenigen Haushalte, die einen Anspruch auf Sozialhilfe haben, diesen nicht geltend macht. Die vorliegende Untersuchung schließt diese Lücken. Zum einen wird ein neues theoretisches Konzept der Anreizethik entwickelt und gemeinsam mit der Lohnabstandshypothese geprüft. Zum anderen werden bei der Analyse der Nichtinanspruchnahme methodische Schwächen der bisherigen Analysen beseitigt. Übertragen auf die Hartz IV-Reform lassen die Ergebnisse erwarten, dass die Nichtinanspruchnahme der Sozialleistung zurückgehen wird, während sich die Anreize zur Überwindung des Bezugs z. T. sogar verschlechtert haben.

The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation

(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is

that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.
