Since 2008 Europe has been in crisis, a financial and debt crisis that spread from the U.S. to all European countries. This thesis aims to provide evidence on the consequences of the crisis for individuals’ labour market outcomes across different countries and regions of Europe and to analyse how the recession has differentially affected sub-groups of the European population. Through the analysis of the longitudinal component of the European Union Statistics on Income and Living Conditions (EU-SILC) dataset, the project sheds light on the labour market trajectories of more than 20,000 Europeans across 11 European countries and 41 regions, before and during the 2008 financial crisis (2005-2012). Sequence and cluster analysis are used to investigate the heterogeneity of individual labour market trajectories across countries and time, while multilevel models are used to study regional labour markets during the years in crisis. The concept of transitional labour markets, as well as theories of labour market segmentation, job competition and job mobility, provide the theoretical framework for this research. The empirical findings show that during the financial crisis, labour market trajectories appear more turbulent and fragmented for the already disadvantaged sub-groups, namely women, younger workers and low educated workers. Furthermore, during the Great recession, an increase in unemployment among men confirms the sectoral profile of the crisis, which hit harder the male-dominated sectors of construction and industry. At the same time, a decrease in inactivity among women is consistent with the added worker effect, according to which women in periods of economic hardship are pushed towards labour market activity in order to contribute to the household income. Countries with weak economies and underperforming labour markets prior to the crisis, such as Greece and Italy, unsurprisingly experienced a deep and persistent crisis, while countries with stronger economies and more inclusive labour markets, such as Denmark and Sweden, managed to survive the crisis with less social harm. The institutional context of the countries offering high chances of employment even during the financial crisis, such as the Nordic countries, lies on the flexicurity of their labour markets. Indeed, flexible labour markets with the use of reduced working-time schemes, i.e. part-time forms of employment, contained unemployment during the financial shock. However, we need to be cautious about flexibility without security or partial deregulation of the markets, implemented in southern European countries, because during the crisis such policies led to further labour market segmentation and thus an increase in employment inequalities. Finally, the region of residence matters in employment outcomes, almost as much as the country of residence. In fact, from the regional analysis of individual employment outcomes during the years of the crisis, an uneven distribution of labour is detected even within the national borders. Summing up, the European crisis should be considered as the sum of national and regional crises.

Die vorliegende Arbeit untersucht die Intensität zwischenbetrieblicher Mobilität von Hochqualifizierten für Deutschland auf regionaler Ebene und überprüft, welcher Wirkungszusammenhang mit regionaler Innovationsfähigkeit besteht. Zentral für die Entstehung von Innovationen werden Wissensspillover angesehen. Hochqualifizierten Arbeitskräften wird eine besondere Rolle zugeschrieben, Wissensspillover auszulösen. In der wissenschaftlichen Literatur wird für Regionen in den USA und den skandinavischen Raum auf den positiven Einfluss zwischenbetrieblicher Mobilität von Hochqualifizierten und der Innovationsentstehung verwiesen. Im Fokus dieser Arbeiten stehen zumeist Beschäftigte im IT-Bereich. Für Deutschland liegen bisher nur wenige Befunde vor. Dementsprechend wird in dieser Arbeit der Frage nachgegangen, wie sich die zwischenbetriebliche Mobilität von Hochqualifizierten räumlich darstellt und welche Auswirkungen regionale Unterschiede im Mobilitätsverhalten auf den Wissenstransfer und damit auf die Innovationsfähigkeit haben. Zur Klärung der Forschungsfrage wird ein Methodenmix angewandt. Auf Grundlage einer quantitativen Auswertung von Berufsbiographien und der Analyse des räumlichen Innovationsgeschehens wird deutlich, dass zwischenbetriebliche Mobilität in einem positiven Zusammenhang mit regionaler Innovationsaktivität steht. Die Befunde für deutsche Regionen bestätigen die Forschungsliteratur zur Wirkungsweise von zwischenbetrieblicher Mobilität auf die Innovationsentstehung. Die qualitative Auswertung von Interviews mit Experten aus Maschinenbaufirmen und regionalen Institutionen in vier deutschen Fallregionen zeigt jedoch, dass in diesem Bereich des produzierenden Sektors spezifische Barrieren existieren, die Einfluss darauf haben, dass Arbeitskräftemobilität nur bedingt zu Wissensspillovern führt. Weiterhin zeigt sich, dass räumliche Unterschiede bei der Wahrnehmung von Arbeitskräftemobilität bestehen, die auf betriebsstrukturelle Merkmale zurückzuführen sind. / This work examines the intensity of inter-firm mobility of highly qualified employees at a local level in Germany and analyses the consequences of labour mobility for the creation of innovation. Knowledge spillovers are considered as a key element in the development of innovative products and processes. A special role in the knowledge transfer mechanism has been attributed to highly qualified employees. Scientific research has shown a positive influence of inter-firm mobility of highly qualified employees and innovation processes for various regions in the USA and Scandinavia. This applies in particular to employees in the IT sector. Concerning Germany one has gained only little insight in in this range of topics so far. Hence, this work addresses the question how the intensity of inter-firm mobility of highly qualified employees looks like at a local level in Germany and which consequences regional disparities of labour mobility have for knowledge spillover effects and thus for the creation of innovation. To tackle the research question, a method mix is applied in this paper. On the basis of quantitative research of nationwide professional biographies and the analysis of spatial innovation activities, it grows apparent that there exists a positive correlation between inter-firm mobility and regional innovation performance. The findings of this analysis of German regions confirm the mechanism between labour mobility and innovation activities in international research. Qualitative research in the form of interviews with experts from mechanical engineering companies and local institutions in four German regions has shown that there are special barriers in this field of the manufacturing sector, which limit the knowledge spillover of labour mobility. Moreover, one has shown spatial differences with regard to the perception of labour mobility, which, however, can be traced back to the structural characteristics of firms in the respective region.
