N2  - The thesis picks up some modern labor market phenomena and contributes to the literature by developing four theoretical models to analyze the effects on labor market outcomes. In particular, it 1) examines how the decision of labor unions to merge or to stay independent depends on the degree of product differentiation, 2) investigates the macroeconomic effects of the deregulation of temporary agency employment, 3) discusses if low-skilled workers will be substituted by automation, and 4) studies how the technological choice of firms in an economy changes due to low-skilled immigration.
The first model focuses on the question of the optimal economic behavior of labor unions under multi-unionism. Developing a right-to-manage model, it analyzes how the decision of labor unions to merge or to stay independent depends on the degree of product differentiation. The model predicts that labor unions have strict incentives to merge if the products are substitutable in consumption, while they want to stay separated for complementary products.
The second model studies the effects of the deregulation of temporary agency employment on labor market outcomes such as wages, unemployment, and the employment structure. It develops a search and matching model with large firms that produce differentiated goods using regularly employed workers that are organized in labor unions and, in addition, temporary agency workers that may search on-the-job for regular employment. The model shows that the legal deregulation of temporary agency employment increases overall employment and the rate of regular employment. The rate of regular employment increases, since labor unions reduce their wage claims in response to the deregulation of temporary agency employment. As the most surprising result, the model predicts a hump-shaped relationship between the degree of legal deregulation of temporary agency employment and its employment rate. This is explained by voluntary, non-institutional firm-level agreements that restrict the use of temporary agency employment in the production and get more important, the more deregulated temporary agency employment is.
The third model incorporates automation in the search and matching framework to reveal if automation creates technological, skill-specific unemployment. The model assumes one-worker firms that operate in a low- or high-skill intensive intermediate sector and employ low- or high-skilled workers, respectively. The two intermediate goods, traditional capital and automation capital in form of industrial robots, 3D printer etc. are used for the production of a final good. Automation capital serves as a perfect substitute for low-skilled labor and an imperfect substitute for high-skilled labor. The model shows that the accumulation of automation capital leads to the creation of technological unemployment. While the unemployment rate of high-skilled workers decreases, low-skilled workers suffer and get replaced by automation capital. Further, the model predicts that wage inequality between high- and low-skilled workers rises as the wage rate of low-skilled workers declines, while the wage rate of high-skilled workers increases.
The fourth model examines how the technological choice of firms in a host country change due to an exogenous inflow of low-skilled immigrants. It uses a search and matching model that considers two type of firms that either use a basic technology or a more advanced technology. Workers match with vacancies randomly and consist of three groups: low- and high-skilled natives and low-skilled immigrants. While the skill distribution of workers is exogenous, firms may endogenously adjust their skill requirements. Another feature of the model is that it captures educational mismatch of high-skilled natives. The model rather intuitively suggests that an increase in low-skilled immigration causes firms to change their behavior and to shift their production towards the basic technology. As a consequence, low-skilled natives benefit from the influx of low-skilled immigrants, while the wage rate of high-skilled natives decreases, whereas their employment rate goes up.
