  abstract  = {This dissertation investigates selected causes and effects of worker mobility between firms in three empirical studies for Germany. Chapter 2 investigates the productivity effects of worker inflows to manufacturing establishments, distinguishing inflows by their previous employers' wage level, as a proxy for productivity. The chapter is motivated by several empirical studies which find that worker inflows from more productive or higher-paying firms increase hiring firms' productivity. The analyses in chapter 2 are based on a unique linked employer-employee data set. The findings indicate that inflows from higher-paying establishments do not increase hiring establishments' productivity, but inflows from lower-paying establishments do. Further analyses suggest that this effect is due to a positive selectivity of such inflows from their sending establishments. These findings can be interpreted as evidence of a reallocation process by which the best employees of lower-paying establishments become hired by higher-paying establishments. This process reflects the assortative pattern of worker mobility in Germany documented by Card et al. (2013) for the past decades. The chapter thus contributes to the literature by linking establishment-level productivity analysis to the assortative pattern of inter-firm worker mobility, thereby providing a micro-foundation for the latter. Chapter 3 focuses on a positive selection of workers moving between firms from another, more specific perspective. The analysis focuses on the importance of regional labor market competition for establishments' apprentice training and poaching of apprenticeship completers. Previous studies have found that firms provide less training if they are located in regions with strong labor market competition. This finding is usually interpreted as evidence of a higher risk of poaching in these regions. Yet, there is no direct evidence that regional competition is positively correlated with poaching. Building on a recently established approach to ex-post identify poaching of apprenticeship completers, this chapter is the first to directly investigate the correlation between regional labor market competition and poaching. Using German administrative data, it is found that competition indeed increases training establishments' probability of becoming poaching victims. However, poaching victims do not change their apprenticeship training activity in reaction to poaching. Instead, the findings indicate that the lower training activity in competitive regions can be attributed to lower retention rates, as well as a less adverse selection and lower labor and hiring costs of apprenticeship completers hired from rivals. Chapter 4 investigates the effects of local broadband internet availability on establishment-level employment growth. The analysis uses data for Germany in the years 2005-2009, when broadband was introduced in rural regions of Western Germany and in large parts of Eastern Germany. Technical frictions in broadband rollout are exploited to obtain exogenous variation in local broadband availability. The results suggest that broadband expansion had a positive effect on employment growth in the Western German service sector and a negative effect in Western German manufacturing, suggesting that broadband expansion has accelerated the reallocation of workers from manufacturing to services. Furthermore, this pattern of results is driven by pronounced positive effects in knowledge- and computer-intensive industries, suggesting that it is the actual use of broadband in the production process that leads to complementary hiring, respectively a slowdown of employment growth, in the respective sectors. For Eastern Germany, no significant employment growth effects are found.},

  abstract  = {Der Lebensmittelonlinehandel in Deutschland gewann, verst{\"a}rkt durch die Covid-19-Pandemie, an Umsatzanteilen im Lebensmitteleinzelhandel. Hierdurch wurden neue Anforderungen an Arbeit und Besch{\"a}ftigung in Deutschland geschaffen. Insbesondere in urbanen R{\"a}umen hat die Lebensmittelzustellung durch neu entstandene Betriebsformen zugenommen. So entstehen durch das Versprechen der Betriebe, Lebensmittel in kurzen Zeitr{\"a}umen zu liefern, verschiedene Logistikstandorte und u.a. urbane Fahrradlieferdienste. W{\"a}hrend Medien und Gewerkschaften bereits vor der Entstehung prek{\"a}rer Arbeitsbedingungen warnen, sind die genauen Auswirkungen des Lebensmittelonlinehandels auf die Entwicklung neuer Arbeitsstandorte und die dort stattfindende Besch{\"a}ftigung nur unzureichend bekannt. Diese Arbeit untersucht den Lebensmittelonlinehandel anhand seiner Betriebsformen, Standorte und Arbeitsprozesse sowie deren Auswirkungen auf Besch{\"a}ftigte in Deutschland. Den konzeptionellen Hintergrund bilden Arbeiten der geographischen Handelsforschung sowie Debatten zu Arbeitsplatzqualit{\"a}t und Besch{\"a}ftigung. F{\"u}r die Analyse sind Prim{\"a}rdaten und Sekund{\"a}rdaten erhoben worden. Es zeigt sich, dass teilweise komplexe Betriebsformen entstehen, bei denen sich die Arbeit und Arbeitsorte ver{\"a}ndern. Zudem entstehen neue Herausforderungen f{\"u}r die Besch{\"a}ftigten (u.a. physische und psychische Belastung), welche in dieser Arbeit identifiziert werden.},
