In our paper published in the British Journal of Industrial Relations Kathrin Weis, Felix Lukowski and myself show how the presence of works councils affects firms’ provision of further training, particularly in the context of rapid technological change in Germany. Using detailed firm-level data from the BIBB Training Panel (2019), the study investigates both the probability that a firm offers training (extensive margin) and the share of employees participating in training (intensive margin), with a specific focus on employees in low-skilled jobs and on differences between firms with varying levels of digital technology. Key Findings The research finds that works…

The our “Navigating uncertainty: Employee participation dynamics in times of crisis” Marek Giebel and myself examine how the Global Financial Crisis (GFC) influenced the creation and dissolution of employer-led internal communication committees (ICCs) in German establishments. These committees—such as roundtable conferences or employee spokespersons—facilitate knowledge sharing and crisis management. Using data from the German IAB Establishment Panel (2004–2018), the study employs a difference-in-differences approach to analyze how crisis exposure affected ICC dynamics. Key Findings Crisis Impact on ICC Introduction Negatively affected establishments (those reporting adverse GFC impacts) were significantly more likely to introduce ICCs during the crisis response phase (2008–2009),…

In our paper “The Impact of a New Workplace Technology on Employees,” (published in the Oxford Bulletin of Economics and Statistics) Marek Giebel and myself investigate how introducing new technologies affects non-monetary working conditions—specifically overtime, training participation, and perceived labor intensity—using detailed German worker-level data from the Socio-Economic Panel (2014–2020). Our analysis reveals that these effects are most pronounced immediately after implementation and vary significantly across occupational and industrial contexts. This paper investigates the impact of the implementation of a new workplace technology on worker outcomes such as overtime, training and perceived productivity. While the effects of new technologies on…

Our study investigates how Germany’s Hartz IV labor market reform (implemented in 2005) reduced workers’ bargaining power and contributed to the decline of the labor share (the ratio of labor compensation to economic output). The research combines theoretical modeling with rigorous empirical analysis to demonstrate that reductions in the “outside option” (unemployment benefits) significantly decreased workers’ negotiation leverage, leading to a measurable drop in the labor share. In this paper we investigate the relevance of bargaining institutions in the decline in labor share. Several explanations for the decline exist, which consider the relevance of technology, globalization and markups. Surprisingly neglected…

In our article of “The Effects of Reforming a Federal Employment Agency on Labor Demand” by Kornelius Kraft and Alexander Lammers, we examine how the Hartz III reform of Germany’s Federal Employment Agency (FEA) influenced employment growth at the establishment level. Our focus is on understanding the real-world impact of modernizing public employment services on firms’ hiring practices and labor demand. In this paper we report the results of an empirical study on the employment growth effects of a policy intervention, explicitly aimed at increasing placement efficiency of the Federal Employment Agency in Germany.
