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.
Real wage cyclicality of newly hired workers
(2013) Stüber, Heiko
Several recent marcoeconomic models rely on rigid wages. Especially wage rigidity of newly hired workers seems to play a crucial role, since the decision of opening a vacancy or not is mainly influenced by their real wages. However, so far little empirical evidence exists on how real wages of newly hired workers react to business cycle conditions. This paper aims at filling this gap for a large economy, namely Germany, by analyzing the cyclical behavior or real wages of newly hired workers while controlling for "cyclical up- and downgrading" in employer/employee matches. For the analysis two endogenous variables are used: either the "typical" (e.g. modal) real wages paid to entrants into particular jobs of particular firms or entrants' individual real wages. The results show that entry-wages are not rigid, but considerably respond to business cycle conditions. This finding strengthens Pissarides' (2009) dismissal of theories based on cyclically rigid hiring wages. Furthermore, I show that the procyclicality of the employment / population ratio is (nearly) identical to the procyclicality of real entry-wages.
Technological unemployment revisited : automation in a searchand matching framework
(2018) Prettner, Klaus; Cords, Dario
Will low-skilled workers be replaced by automation? To answer this question, we set up a search and matching model that features two skill types of workers and includes automation capital as an additional production factor. Automation capital is a perfect substitute for low-skilled workers and an imperfect substitute for high-skilled workers. Using this type of model, we show that the accumulation of automation capital decreases the labor market tightness in the low-skilled labor market and increases the labor market tightness in the high-skilled labor market. This leads to a rising unemployment rate of low-skilled workers and a falling un- employment rate of high-skilled workers. In addition, automation leads to falling wages of low-skilled workers and rising wages of high-skilled workers.
