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.

FDI, Human Capital and Income Convergence — Evidence for European Regions
in: Economic Systems, No. 2, 2016
Abstract
This study examines income convergence in regional GDP per capita for a sample of 269 regions within the European Union (EU) between 2003 and 2010. We use an endogenous broad capital model based on foreign direct investment (FDI) induced agglomeration economies and human capital. By applying a Markov chain approach to a new dataset that exploits micro-aggregated sub-national FDI statistics, the analysis provides insights into regional income growth dynamics within the EU. Our results indicate a weak process of overall income convergence across EU regions. This does not apply to the dynamics within Central and East European countries (CEECs), where we find indications of a poverty trap. In contrast to FDI, regional human capital seems to be associated with higher income levels. However, we identify a positive interaction of FDI and human capital in their relation with income growth dynamics.

Dual Labor Markets at Work: The Impact of Employers’ Use of Temporary Agency Work on Regular Workers’ Job Stability
in: ILR Review, No. 5, 2016
Abstract
Fitting duration models on an inflow sample of jobs in Germany starting in 2002 to 2010, the author investigates the impact of employers’ use of temporary agency work on regular workers’ job stability. In line with dual labor market theory, the author finds that nontemporary jobs are significantly more stable when employers use temporary agency workers. The rise in job stability stems mainly from reduced transitions into nonemployment, suggesting that nontemporary workers are safeguarded against involuntary job losses. The findings are robust to controlling for unobserved permanent employer characteristics and changes in the observational window that comprises the labor market disruption of the Great Recession.

Spinoffs in Germany: Characteristics, Survival, and the Role of their Parents
in: Small Business Economics, No. 1, 2016
Abstract
Using a 50 % sample of all private sector establishments in Germany, we report that spinoffs are larger, initially employ more skilled and more experienced workers, and pay higher wages than other startups. We investigate whether spinoffs are more likely to survive than other startups, and whether spinoff survival depends on the quality and size of their parent companies, as suggested in some of the theoretical and empirical literature. Our estimated survival models confirm that spinoffs are generally less likely to exit than other startups. We also distinguish between pulled spinoffs, where the parent company continues after they are founded, and pushed spinoffs, where the parent company stops operations. Our results indicate that in western and eastern Germany and in all sectors investigated, pulled spinoffs have a higher probability of survival than pushed spinoffs. Concerning the parent connection, we find that intra-industry spinoffs and spinoffs emerging from better-performing or smaller parent companies are generally less likely to exit.

How Selective Are Real Wage Cuts? A Micro-analysis Using Linked Employer–Employee Data
in: LABOUR: Review of Labour Economics and Industrial Relations, No. 4, 2015
Abstract
Using linked employer–employee panel data for Germany, we investigate whether firms implement real wage reductions in a selective manner. In line with insider–outsider and several strands of efficiency wage theory, we find strong evidence for selective wage cuts with high-productivity workers being spared even when controlling for permanent differences in firms' wage policies. In contrast to some recent contributions stressing fairness considerations, we also find that wage cuts increase wage dispersion among peers rather than narrowing it. Notably, the same selectivity pattern shows up when restricting our analysis to firms covered by collective agreements or having a works council.

Does the Plant Size–wage Differential Increase with Tenure? Affirming Evidence from German Panel Data
in: Economics Letters, 2015
Abstract
We show that the major part of the plant size–wage premium in Germany is reflected in different wage growth patterns in plants of different size. This is consistent with the hypothesis that large firms ‘produce’ more skilled workers over time.

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)
