    Essays on the impact of temporary agency work on wages and employment
    (2018) Baudy, Philipp; Beißinger, Thomas
    The thesis contributes to the theoretical discussion of the effects of temporary agency work and picks up three different issues that have not been analyzed yet. It provides three theoretical models 1) to discuss the optimal economic behavior of firms and labor unions when firms threaten to use temporary agency employment in the bargaining process, 2) to examine the macroeconomic effects of the deregulation of temporary agency work that took, and still takes, place in many countries in the last decades, and 3) to study how the technological choice of firms in the economy changes due to the legal deregulation of temporary agency work. The first model focuses on the question of the optimal economic behavior of the bargaining parties. Developing a monopoly union model, it analyzes how and to what extent firms can strategically use the threat of temporary agency employment to dampen the wage claims of labor unions. Furthermore, the model discusses how labor unions optimally behave and respond to these threats. It is shown that labor unions may find it optimal to accept lower wages to prevent firms from using temporary agency workers. The decision of the labor union to oppose or accept the firms threat is based on the attempt to minimize the loss in its utility. While labor unions suffer from the potential use of temporary agency employment in terms of their utility, firms gain from increasing profits and an extended employment level per firm. If unions do not oppose temporary agency work, the model suggests that labor unions increase their wage claims for the remaining regular workers to a level that even exceeds the claims of the labor union if there is no threat at all. Hence, an intensive use of temporary agency workers in high-wage firms may be the cause and not the consequence of the high wage level in those firms. The second model concentrates on the effects of the deregulation of temporary agency employment on macroeconomic determinants like wages, unemployment, and the employment structure. Using the matching framework, it provides a first contribution that combines labor unions and temporary agency work in this modeling setup. Large firms produce differentiated goods employing regular workers that are organized in labor unions and, optionally, using temporary agency work for parts of the production. Furthermore, there is a special emphasis on the flows from temporary agency to regular employment, which is modeled as on-the-job search. The model shows that the deregulation of temporary agency work leads to a reduction in overall unemployment. Surprisingly, this favors regular employment due to lower wages that arise from the impact that the more attractive production alternative temporary agency employment has on labor union wage bargaining. The most interesting finding, however, is that there is a hump-shaped relationship between the degree of institutional deregulation of temporary agency work and its rate of employment. This is explained by the fact that voluntary non-institutional, firm-level regulations come into play and get the more important, the less regulated temporary agency employment is. They have a counter-effect on the costs of temporary agency work that is lowered by the deregulation. Additionally, even if the model does not conceal that individual workers suffer from declining wages, it shows that regular employment benefits from the deregulation of temporary agency employment. The third model examines how the technological choice of firms in an economy changes due to the availability of temporary agency employment as a production alternative that gets cheaper and, therefore, more attractive the less regulated it is. The model uses the matching framework with two types of jobs that differ in their productivity and workers that are randomly matched with temporary or regular job vacancies. The analysis reveals how the decision of firms with which technology to enter the market and to produce with changes with the deregulation of temporary agency employment. Regular and temporary agency workers produce the same good but use different technologies. Temporary agency work is less expensive to hire than regular workers as direct labor costs are lower. However, job destruction and labor turnover is higher in this employment type. The model rather intuitively suggests that the legal deregulation of temporary agency employment deteriorates the technology level used in the economy, leads to a more intensive use of the less advanced technology, and increases temporary agency employment. Regular workers are shown to suffer from declining wages while the labor income of temporary agency workers increases. However, the model also provides an advice for economic policy by suggesting that subsidies or other forms of support for directed investments in technological progress of more advanced technologies may be suitable to dampen the macroeconomic effects of the deregulation of temporary agency employment.

    Four essays on the impact of institutions, technological change, and globalization on labor market outcomes
    (2019) Cords, Dario; Beißinger, Thomas
    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.

    Matching und Zeitarbeit : Theoretische Analysen zu den Auswirkungen der Leiharbeit auf den Arbeitsmarkt
    (2012) Pfleger, Stefan; Beißinger, Thomas
    Since 1990 temporary agency work has increased rapidly in most western countries. Despite that fact, the academic research about this trend is still at the beginning. This dissertation contributes to the theoretical field of research by investigating the effects of the existence of temporary work agencies on the labor market. Using different kinds of matching-models, the analysis focuses on the identification of the growth-determinants of temporary agency work and the various kinds of effects that temporary agency work can have on the performance of the labor market. Chapter 2 gives an overview about the phenomenon ?temporary agency work?, its legal framework in Germany and the motives of firms and individuals, which use the services of temporary work agencies. In addition, some data of the structure and development of temporary agency work in Germany is presented. An introduction into (standard) matching-models of the labor market is given in chapters 3 to 5. Afterwards, the traditional matching-framework is used to analyze the intermediation-function of temporary work agencies. In Chapter 6 to 8 a modification of the traditional matching-framework is made by explicitly incorporating temporary agency work as an additional labor market segment. By doing so, it is possible to analyze the interaction with other kinds of labor market institutions, such as employment protection. The model presented in Chapter 6 investigates whether the deregulation of temporary agency work has contributed to its rapid growth. Furthermore it is discussed under which circumstances the expansion of the temporary work sector leads to the growding-out of regular jobs. Afterwards, an empirical analysis examines the effects of the deregulation process on the growth of temporary agency work in Germany. Chapter 7 shows that there are also factors outside the temporary work sector that can explain its growing importance. The model developed in this chapter is used to analyze the effects of firing-costs on the temporary work sector. Furthermore it is asked which effects the existence of the temporary work sector has on labor market performance when the regular sector becomes more rigid. The model developed in chapter 8 analyzes the wage-effects of temporary work. Initially, the analysis focuses on the effects of a change of the wage-differential between regular and temporary agency work. Finaly it is shown what effects the growth of the agency work sector can have on the wages of temporary and regular workers.

    Three essays on the labor market effects of technological change and unemployment benefits
    (2023) Brall, Franziska; Beißinger, Thomas
    The dissertation essentially contributes to the discourse on how technological change and a reduction in unemployment benefits affect the labor market. The thesis incorporates an empirical analysis of the influence of automation technologies on wage inequality in Germany. Additionally, the dissertation introduces a novel general equilibrium model to analyze the impact of technological change on the wage setting behavior of labor unions and reevaluate the labor market effects of a cut in unemployment benefits. The first essay contributes to the existing literature in examining the relative importance of automation technologies on wage inequality in the German manufacturing sector between 1996 and 2017. The analysis introduces a novel measure of automation threat, combining occupation- and requirement-specific scores of automation risk with sector-specific robot densities. Using the RIF-based Oaxaca–Blinder decomposition method, the analysis demonstrates that automation threat significantly contributes to wage inequality, in addition to the commonly used demographic factors. On the one hand, there is an observable trend towards occupations with medium automation threat, accompanied by decreasing shares of occupations with high and low automation threat. Due to the fact that within-group wage inequality is the lowest in the group with the highest automation threat, those compositional changes contribute to increasing wage inequality. On the other hand, an increasing wage dispersion between occupations with low automation threat (containing especially non-routine tasks) and occupations with high automation threat (containing especially routine tasks) contributes to rising wage inequality. This is in line with the predictions of routine-biased technical change, where technology particularly substitutes routine tasks. The second essay develops a novel modeling framework for the analysis of skill-biased technical change (SBTC), combining the task approach, wage setting by labor unions, as well as search and matching frictions. The important insight from this analysis is that changes in the firm’s assignment of tasks to low- and high-skilled workers have an impact on the wage setting power of labor unions. The effect of such a change in the task allocation on the labor demand elasticity, and consequently on the labor union’s wage markup, is ambiguous. This has consequences for the effects of SBTC. Unlike the conventional result that SBTC has a positive impact on employment and wages of low-skilled workers, the task-based matching model presents the possibility that low-skilled workers may instead experience either higher unemployment or lower real wages. The model is calibrated to German and French data for the periods 1995-2005 and 2010-2017 to illustrate that the impact of SBTC may even change its sign over time. The results depend on the shape of the task productivity schedule, which reflects the substitutability of high-and low-skilled workers. The third essay revisits the labor market effects of a reduction in unemployment benefits using a modified version of the previously developed task-based matching model. The analysis demonstrates that a cut in low-skilled unemployment benefits triggers a reallocation of tasks towards low-skilled workers. This leads to additional effects on labor market outcomes that are disregarded in the prevailing literature. To highlight the importance of endogenous task allocation, the task-based matching model with exogenous and constant task allocation is considered. Both model variants are calibrated to analyze the effects of the Hartz IV reform in Germany, which involved a substantial cut in unemployment benefits. The calibration reveals a remarkable decrease in the low-skilled unemployment rate by 4 percentage points resulting from Hartz IV. In the case of exogenous and constant task allocation, the decline is limited to 3.4 percentage points, but there are stronger effects on low- and high skilled wages, causing wage inequality to rise more sharply. The results emphasize the importance of considering endogenous task allocation in the evaluation of labor market reforms.
