Firm Dynamics and Employment Outcomes
The group “Firm Dynamics and Employment Outcomes” analyses the foundation, evolution, and failure of firms, and subsequent consequences for individuals and regions. The group works on research questions around firm behaviour to explain recent phenomena such as business dynamism slowdown and wage inequality.
A central question to understand firm dynamism, mobility, innovation and the process of creative destruction is on the role of government interference. In this respect, the team analyses how connections of firms to politicians shape the business environment and to what extent firms benefit from having a political connection.
At the firm level, the group studies performance measures such as employment, sales, and market exit and investigates public procurement contracts, subsidies and political initiatives in terms of law proposals and draft laws that implicitly may generate higher entry barriers and distorts competition. This research will be informative for the overall economic environment and economic prosperity.
The way economies generate economic prosperity is central to our understanding of social mobility and welfare. Over the last three decades, Germany and the United States have shown similar productivity improvements. The way these improvements have been generated, however, differ remarkably. While startups in the United States are well-known for their innovation and radical advancements, the German business model relies to a large extent on established incumbent firms in the process of innovation and new technologies. The research group considers empirically and theoretically the role of entrepreneurship in this process and how it differs between Germany and the United States.
Understanding firm behaviour and the role of firms in our society contributes to the political and academic discussion on wage inequality and regional disparities. The sorting process of high productive workers into high productive firms has amplified over the last three decades with important implications for wages and aggregate inequality. Thus, the group examines the consequences of wage inequality between firms and to what extent selective mobility contributes to wage disparities.
The research group “Firm Dynamics and Employment Outcomes” further studies implications of innovative activities in the form of patenting on within-firm wage inequality. Examining impacts of new technologies and worker-level consequences will be informative about winners and losers in our society and informs policy makers on how to take action in terms of reskilling certain groups of the workforce.
The research group makes use of various administrative, survey and hand-collected data. The Establishment History Panel (BHP) provided by the Institute for Employment Research (IAB) and the Mannheim Enterprise Panel (MUP) provided by the Leibniz Centre for European Economic Research (ZEW) provide firm-level information on the performance of firms over time. At the individual level, IAB’s Integrated Employment Biographies (IEB) allows to study regional and wage mobility patterns of workers. European Patent Office data provide the basis for patenting activities. Web-scraped and survey data on political activities and opinions are exploited to study differential behaviour of politicians in parliament.

The Rise of Populist Parties in Europe: The Dark Side of Globalization and Technological Change?
VolkswagenStiftung
Globalisation may have increased prosperity in general, but has also led to unemployment, wage inequality, outward migration and, thus, ageing populations in many European regions. This project examines whether these economic burdens lead to votes for populist parties.

Firm Wage Differentials in Imperfect Labour Markets: The Role of Market Power and Industrial Relations in Rent Splitting between Workers and Firms
German Research Foundation (DFG)
The main purpose of this proposal is to grasp a firmer understanding of how employment rents are split between workers and employers in imperfect labour markets and how labour market institutions, such as unions and works councils, influence the distribution of rents. In that it not only promises new insights into the wage formation process and the likely consequences of important labour market trends like falling unionisation and worker codetermination, but also promises to inform important public policy debates, such as which rights should be granted to organised labour.

Wage and Employment Effects of Bankruptcies
German Research Foundation (DFG)
The project analyzes the process and the consequences of firm failure. For the first time, evidence on the consequences of small firms’ bankruptcy on employees’ earnings and wages is provided. The project e.g. shows that employees of small firms are more likely to see their employer failing but, at the same time, face smaller earnings and wage losses than employees displaced from larger firms. Check the below research articles for further insights.

Women Move Differently: Job Separations and Gender
in: Journal of Labor Research, No. 4, 2012
Abstract
Using a large German linked employer–employee data set and methods of competing risks analysis, this paper investigates gender differences in job separation rates to employment and nonemployment. In line with descriptive evidence, we find lower job-to-job and higher job-to-nonemployment transition probabilities for women than men when controlling for individual and workplace characteristics and unobserved plant heterogeneity. These differences vanish once we allow these characteristics to affect separations differently by gender. When additionally controlling for wages, we find that both separation rates are considerably lower and also significantly less wage-elastic for women than for men, suggesting an interplay of gender differences in transition behaviour and the gender pay gap.

Works Councils and Establishment Productivity
in: ILR Review, No. 4, 2012
Abstract
Declining union density in many industrialized countries increases interest in alternative forms of employee representation, such as works councils. The German works council is one of the most powerful forms of worker representation in developed countries, but little is known of its causal effect on productivity. The author used a large linked employer-employee panel data set to examine this issue. Comparing firms with and without a works council, the author finds that establishments with a works council are on average 6.4% more productive; but he also presents evidence that this figure underestimates the true productivity effect of works councils.

The Productivity Effect of Temporary Agency Work: Evidence from German Panel Data
in: Economic Journal, No. 562, 2012
Abstract
This study investigates the effect of temporary agency work on the user firm’s productivity. We hypothesise that using temporary agency work to enhance numerical flexibility and to screen job candidates may increase productivity, whereas temporary workers’ lower firm-specific human capital and spillover effects on the user’s permanent employees may adversely affect productivity. Other than the sparse existing literature on this issue, we exploit a large panel data set and control for time-invariant and time-varying unobserved heterogeneity by using the system GMM estimator. We find a robust hump-shaped effect of the extent of temporary agency work on the user firm’s productivity.

Do Women Benefit from Competitive Markets? Product Market Competition and the Gender Pay Gap in Germany
in: Economics Bulletin, No. 2, 2012
Abstract
Using a large linked employer–employee dataset for Germany with a direct plant-level measure of product market competition and controlling for job-cell fixed effects, we investigate whether relative wages of women benefit from strong competition. We find that the unexplained gender pay gap is about 2.4 log points lower in West German plants that face strong product market competition than in those experiencing weak competition, whereas no such link shows up for East Germany.

Works Councils and Firm Profits Revisited
in: British Journal of Industrial Relations, No. 1, 2011
Abstract
As they are employee associations, it is typically presumed that works councils redistribute economic rents from firm owners to workers. And indeed, the empirical literature suggests that German works councils reduce profits. The studies on the profitability effect of works councils mainly use self-reported subjective profit evaluations of managers as the dependent variable. I argue that these are poor measures of real profits. Newly available information on firms' capital stock allows me to revisit the profit effect now using an objective profit measure. When utilizing the subjective measure I find the standard results; with the objective measure, however, the works council effect on profits is positive and significant.

Oxytocin, Empathy, Altruism and Charitable Giving: Experimental Evidence from Blood Donations
in: IWH Discussion Papers, No. 4, 2023
Abstract
We conducted a field experiment in the natural setting of blood donations to test how oxytocin relates to empathy and altruism. We randomly assigned blood donors in the Croatian Institute for Transfusion Medicine to three groups with the aim to induce different levels of empathy by showing a neutral video to the donors from the control group and an emotional to the donors from the first and second treatment groups. In addition to watching the emotional video, donors from the second treatment group are given a gift which relates to the emotional story from the video. We find no effect of our treatment on induced levels of oxytocin. Null effects of our treatments could be explained by the above average baseline levels of oxytocin and inability of our treatments to provoke emotional stimuli in blood donors. Nonetheless, for our empathy measures we find the effect of gift exchange on empathic concerns, but not on perspective taking. After our experimental treatments, we followed the return of our blood donors for a whole year. We find that only variable which consistently predicts return for blood donation in stated period is the number of previous donations. From policy perspective it is an important finding. Especially for hospitals and other blood providers when faced with time and resource constraints.

Identifying Rent-sharing Using Firms‘ Energy Input Mix
in: IWH Discussion Papers, No. 19, 2022
Abstract
We present causal evidence on the rent-sharing elasticity of German manufacturing firms. We develop a new firm-level Bartik instrument for firm rents that combines the firms‘ predetermined energy input mix with national energy carrier price changes. Reduced-form evidence shows that higher energy prices depress wages. Instrumental variable estimation yields a rent-sharing elasticity of approximately 0.20. Rent-sharing induced by energy price variation is asymmetric and driven by energy price increases, implying that workers do not benefit from energy price reductions but are harmed by price increases. The rent-sharing elasticity is substantially larger in small (0.26) than in large (0.17) firms.

Identifying Bankruptcies in German Social Security Data
in: FDZ-Methodenreport, No. 10, 2017
Abstract
In empirischen Studien über Firmenschließungen wird häufig die Notwendigkeit betont, zwischen verschiedenen Arten von Schließungen, z.B. freiwilligen und unfreiwilligen, zu unterscheiden. Dieser Methodenreport erläutert vor diesem Hintergrund, wie im Betriebs-Historik-Panel (BHP) Betriebsstillegungen aufgrund von Insolvenzen identifiziert werden können. Insolvenzen können im Gegensatz zu anderen Schließungen eindeutig als Ausdruck ökonomischen Scheiterns und somit als unfreiwillige Schließungen interpretiert werden. (Autorenreferat, IAB-Doku)
