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.

Explaining Wage Losses After Job Displacement: Employer Size and Lost Firm Wage Premiums
in: Journal of the European Economic Association, No. 5, 2021
Abstract
This paper investigates whether wage losses after job displacement are driven by lost firm wage premiums or worker productivity depreciations. We estimate losses in wages and firm wage premiums, the latter being measured as firm effects from a two-way fixed-effects wage decomposition. Using new German administrative data on displacements from small and large employers, we find that wage losses are to a large extent explained by losses in firm wage premiums and that premium losses are largely permanent. We show that losses strongly increase with pre-displacement employer size. This provides an explanation for large and persistent wage losses reported in previous displacement studies typically focusing on large employers, only.

Do Digital Information Technologies Help Unemployed Job Seekers Find a Job? Evidence from the Broadband Internet Expansion in Germany
in: European Economic Review, February 2021
Abstract
This paper studies effects of the introduction of a new digital mass medium on reemployment of unemployed job seekers. We combine data on broadband internet availability at the local level with German individual register data. We address endogeneity by exploiting technological peculiarities that affected the roll-out of broadband internet. Results show that broadband internet improves reemployment rates after the first months in unemployment for males. Complementary analyses with survey data suggest that internet access mainly changes male job seekers’ search behavior by increasing online search and the number of job applications.

Firm Wage Premia, Industrial Relations, and Rent Sharing in Germany
in: ILR Review, No. 5, 2020
Abstract
The authors use three distinct methods to investigate the influence of industrial relations on firm wage premia in Germany. First, ordinary least squares (OLS) regressions for the firm effects from a two-way fixed-effects decomposition of workers’ wages reveal that average premia are larger in firms bound by collective agreements and in firms with a works council, holding constant firm performance. Next, recentered influence function (RIF) regressions show that premia are less dispersed among covered firms but more dispersed among firms with a works council. Finally, in an Oaxaca–Blinder decomposition, the authors find that decreasing bargaining coverage is the only factor they consider that contributes to the marked rise in premia dispersion over time.

Birds, Birds, Birds: Co-worker Similarity, Workplace Diversity and Job Switches
in: British Journal of Industrial Relations, No. 3, 2020
Abstract
We investigate how the demographic composition of the workforce along the sex, nationality, education, age and tenure dimensions affects job switches. Fitting duration models for workers’ job‐to‐job turnover rate that control for workplace fixed effects in a representative sample of large manufacturing plants in Germany during 1975–2016, we find that larger co‐worker similarity in all five dimensions substantially depresses job‐to‐job moves, whereas workplace diversity is of limited importance. In line with conventional wisdom, which has that birds of a feather flock together, our interpretation of the results is that workers prefer having co‐workers of their kind and place less value on diverse workplaces.

Who Buffers Income Losses after Job Displacement? The Role of Alternative Income Sources, the Family, and the State
in: LABOUR: Review of Labour Economics and Industrial Relations, No. 3, 2020
Abstract
Using survey data from the German Socio‐Economic Panel (SOEP), this paper analyses the extent to which alternative income sources, reactions within the household context, and redistribution by the state attenuate earnings losses after job displacement. Applying propensity score matching and fixed effects estimations, we find that income from self‐employment reduces the earnings gap only slightly and severance payments buffer losses in the short run. On the household level, we find little evidence for an added worker effect whereas redistribution by the state within the tax and transfer system mitigates income losses substantially.

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)
