"The authors investigate immigrants' and natives' labor supply to the firm within an estimation approach based on a dynamic monopsony framework. Applying duration models that account for unobserved worker heterogeneity to a large administrative employer–employee data set for Germany, they find that immigrants supply labor less elastically to firms than do natives. Under monopsonistic wage setting, the estimated elasticity differential predicts a 7.7 log points wage penalty for immigrants thereby accounting for the entire unexplained native–immigrant wage differential of 5.8 to 8.2 log points. When further distinguishing immigrant groups differing in their time spent in the German labor market, their immigration cohort, and their age at entry, the authors find that the observed unexplained wage differential is larger for those groups that show a larger elasticity differential relative to natives. These findings not only suggest that search frictions are a likely cause of employers' more pronounced monopsony power over their immigrant workers but also imply that employers profit from discriminating against immigrants."

"This paper evaluates the impact on temporary agency workers' job satisfaction of a reform that considerably relaxed regulations covering the temporary help service sector in Germany. We isolate the causal effect of this reform by combining a difference-in-difference and matching approach and using rich survey data. We find that the change of the law substantially decreased agency workers' job satisfaction while regular workers' job satisfaction remained unchanged. Further analysis reveals that the negative effect on agency workers' job satisfaction can be attributed to a decrease in wages and an increase in perceived job insecurity. These results are also robust to the use of different specifications and placebo tests."

"This paper analyzes wage assimilation of ethnic German immigrants to Germany using unique administrative data that include an administrative estimate of immigrants' expected wage in Germany at the time of migration. We find that a 10% higher wage potential translates into a 1.6% higher wage in Germany when also controlling for educational attainment, thus pointing at partial transferability of pre-migration skills to the host country's labor market. We also document that wage assimilation is significantly accelerated for immigrants with higher wage potentials. Our results are both in line with complementarities between pre-migration skills and host country-specific human capital and a U-shaped pattern of immigrants' job mobility with initial downgrading and subsequent upgrading."

"It is a well-known fact that temporary agency workers accept high wage penalties compared to permanent workers. However, remarkably little is known about the wages of workers who regularly take jobs in the temp sector or who do temp work for a substantial period of time. Based on a rich administrative data set, the effect of the intensity of agency employment on the temp wage gap in Germany is estimated. Using a two-stage selection-corrected method within a panel data framework, the paper shows that the wage gap for temps with low treatment intensity is high but decreases with time spent in the sector, presumably reflecting that temporary agency workers are able to accumulate human capital while employed in the temp sector. However, agency employment seems to stigmatize those workers who move frequently from one temp job to the next."

"We investigate the labor market effects of immigration in Denmark, Germany and the UK, three countries which are characterized by considerable differences in labor market institutions and welfare states. Institutions such as collective bargaining, minimum wages, employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks, and, hence, the labor market effects of immigration. We employ a wage-setting approach which assumes that wages decline with the unemployment rate, albeit imperfectly. We find that wage flexibility is substantially higher in the UK compared to Germany and, in particular, Denmark. As a consequence, immigration has a much larger effect on the unemployment rate in Germany and Denmark, while the wage effects are larger in the UK. Moreover, the elasticity of substitution between natives and foreign workers is high in the UK and particularly low in Germany. Thus, the preexisting foreign labor force suffers more from further immigration in Germany than in the UK."

"Since 2003, the German Public Employment Service has been experimenting with the contracting-out of various services. One of the new labour market programmes is Personnel Service Agencies (PSAs), which provide client firms with jobseekers on a temporary assignment basis and are responsible for integrating jobseekers into non-subsidized employment. By contracting-out employment services, the Public Employment Service seeks to exploit efficiency gains characteristic of enterprises that compete in quasi-markets. In order to integrate jobseekers as rapidly as possible, a result-oriented system of incentives has been developed. This article describes the institutional setting and examines its appropriateness for efficient job placement services."

"The employment duration of workers in temporary help agencies is seen as an important indicator of their job quality. Most of the countries that regulate temporary agency employment do so to ensure at least a minimal level of employment stability. Over the past three decades Germany has repeatedly liberalized the law on temporary agency employment. These successive reforms should have affected the employment duration in the temporary employment sector. Applying a mixed proportional hazard rate model to administrative data, the authors examine whether employment duration changed in response to these reforms. They find that successive extensions of the maximum assignment period significantly increased average employment duration, while "liberalizing" legislation, such as that allowing fixed-term contracts, tended to reduce it."
