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.

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.

The Levelling Effect of Product Market Competition on Gender Wage Discrimination
in: IZA Journal of Labor Economics, Vol. 3 (19), 2014
Abstract
Using linked employer–employee panel data for West Germany that include direct information on the competition faced by plants, we investigate the effect of product market competition on the gender pay gap. Controlling for match fixed effects, we find that intensified competition significantly lowers the unexplained gap in plants with neither collective agreements nor a works council. Conversely, there is no effect in plants with these types of worker codetermination, which are unlikely to have enough discretion to adjust wages in the short run. We also document a larger competition effect in plants with few females in their workforces. Our findings are in line with Beckerian taste-based employer wage discrimination that is limited by competitive forces.
Do Better Pre-migration Skills Accelerate Immigrants' Wage Assimilation?
in: Labour Economics, Vol. 30, 2014
Abstract
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.
Lingering Illness or Sudden Death? Pre-exit Employment Developments in German Establishments
in: Industrial and Corporate Change, Vol. 23 (4), 2014
Abstract
Using a large administrative data set for Germany, this article compares employment developments in exiting and surviving establishments. Applying a matching approach, we find a clear “shadow of death” effect reflecting lingering illness: in both West and East Germany establishments shrink dramatically already several years before closure, employment growth rates differ strongly between exiting and surviving establishments, and this difference becomes stronger as exit approaches. Moreover, we provide first evidence that prior to exit the workforce becomes on average more skilled, more female, and older in exiting compared to surviving establishments. These effects are more clearly visible in West than in East Germany.
What Can We Learn from Bargaining Models about Union Power? The Decline in Union Power in Germany, 1992–2009
in: Manchester School, Vol. 82 (3), 2014
Abstract
Building on the right-to-manage model of collective bargaining, this paper tries to infer union power from the observed results in wage setting. It derives a time-varying indicator of union strength taking account of taxation, unemployment benefits, and the labour market situation and confronts this indicator with annual data for Germany. The results show that union power did not change much from 1992 to 2002 but fell markedly (by about one-third) from 2002 to 2007 in the aftermath of substantial labour market reforms.
Establishment Survival in East and West Germany: A Comparative Analysis
in: Schmollers Jahrbuch, Vol. 134 (2), 2014
Abstract
Anhand umfangreicher administrativer Daten vergleicht diese Studie die Entwicklung der Überlebenschancen neu gegründeter Betriebe in West- und Ostdeutschland für die Jahre 1994 bis 2008. Eine zentrale Frage lautet dabei, ob eine Angleichung der Überlebensraten zwischen West- und Ostdeutschland zu beobachten ist. Anhand von Methoden der Verweildaueranalyse kommt die Studie zu dem Ergebnis, dass sich die Überlebenschancen neu gegründeter Betriebe zu Beginn des Beobachtungszeitraums nicht stark zwischen West- und Ostdeutschland unterscheiden. In den Jahren 1998 und 1999 steigt die Schließungswahrscheinlichkeit in Ostdeutschland stark an, in Westdeutschland jedoch nicht, was vermutlich auf eine Änderung der Subventionspolitik für Betriebe in Ostdeutschland zurückzuführen ist. Seit der Jahrtausendwende nimmt der Unterschied in den Schließungswahrscheinlichkeiten zwischen West- und Ostdeutschland ab, was auf eine Angleichung der Überlebenschancen hindeutet.

Off the Labor Supply Curve: The Zero Employer Size Wage Effect Within Large Firms
in: IWH Discussion Papers, No. 8, 2026
Abstract
We revisit the employer size wage effect (ESWE) – arguably the most basic and influential departure from the law of one price for labor. Our main result is that this canonical fact disappears completely across establishments within the same firm, even though they operate in different local labor markets. We uncover and dissect this fact by including a firm fixed effect in otherwise standard cross-sectional regressions of wages on establishment size. We implement this demanding specification in population-wide triple-linked firm-establishment-employee data in Germany. This result is new in the ESWE literature (for which our paper also provides the first systematic meta-analysis). This wage-size decoupling is hard to square with the view that employment is determined along a finitely elastic employerspecific labor supply curve – i.e., employers pay exactly the minimum needed for the quantity of labor, but no more – the foundation of the monopsony view. By contrast, large multi-establishment firms (MEF) appear to hire off their labor supply curves (or those curves are very elastic), pay wage premia above the monopsonistic minimum, and leave excess labor supply. We find some evidence for a reemergence of the ESWE within low-premium MEFs. Overall, at least for the 25% of German employment in large firms for which the ESWE disappears, wage setting and employment determination may be better accounted for by alternative models, namely accommodating above-market-clearing wage premia and rationing of labor supply, such as efficiency wage theories.
Patents, Firm Rents, and Worker Compensation: Causal Evidence from Quasi-random Patent Allocation
in: IWH Discussion Papers, No. 6, 2026
Abstract
This paper provides new causal evidence on how patent allowances affect firms and their employees based on quasi-random assignment of patent applications to examiners. Exploiting employer-employee records with newly linked German firm data and web-scraped patent documents, we show that patent-induced shocks reduce firm exit, improve productivity, and increase wages, with rent-sharing elasticities between 0.10 and 0.21. Wage gains are broadly observed across occupational tasks, with high heterogeneity: managers benefit disproportionately in publicly traded firms, whereas broader wage increases accrue to workers in non-traded firms. Our findings highlight the role of institutional features and firm organization in shaping how rents are shared.
The Geography of Worker-Firm Sorting: Drivers of Rising Colocation
in: IWH Discussion Papers, No. 22, 2025
Abstract
Spatial segregation of low- and high-wage workers is a persistent economic issue with broad social implications. Using social security data and an AKM wage decomposition, this paper examines spatial wage inequality in West Germany. Spatial inequality in log wages rose sharply between 1998 and 2008, mainly due to increased variance in worker pay premiums across regions (48%) and stronger positive spatial assortative matching of workers and establishments (40%), i.e. colocation. Changes in establishment wage premia are mostly unrelated to rising colocation whereas labor mobility even reduced it. Instead, growth in worker pay premiums among stayers was concentrated in regions where high-wage workers and high-wage establishments were overrepresented already in the 1990s and, thus, magnified pre-existing colocation leading to ‘colocation without relocation’. Germany’s rising trade surplus, especially with Eastern Europe, boosted stayers’ worker pay premiums in those ex-ante high-wage regions and fully explains rising colocation.
The Distribution of National Income in Germany, 1992-2019
in: IWH Discussion Papers, No. 25, 2024
Abstract
This paper analyzes the distribution and composition of pre-tax national income in Germany since 1992, combining personal income tax returns, household survey data, and national accounts. Inequality rose from the 1990s to the late 2000s due to falling labor incomes among the bottom 50% and rising incomes in the top 10%. This trend reversed after 2007 as labor incomes across the bottom 90% increased. The top 1% income share, dominated by business income, remained relatively stable between 1992 and 2019. A large share of Germany’s top 1% earners are non-corporate business owners in labor-intensive professions. At least half of the business owners in P99-99.9 and a quarter in the top 0.1% operate firms in professional services – a pattern mirroring the United States. From 1992 to 2019, Germany’s top 0.1% income concentration exceeded France’s and matched U.S. levels until the late 2000s.
Do Politicians Affect Firm Outcomes? Evidence from Connections to the German Federal Parliament
in: IWH Discussion Papers, No. 15, 2024
Abstract
We examine how connections to German federal parliamentarians influence firm dynamics using a novel dataset linking politicians and election candidates to the universe of firms. To identify the causal effects of political access, we exploit (i) new appointments to the company leadership team and (ii) discontinuities around the marginal seat of party election lists. Results reveal that political connections reduce firm exits and gradually increase employment growth, with heterogeneous productivity effects depending on the political mandate. Incorporating data on credit ratings, subsidies, and procurement contracts allows us to identify the mechanisms driving the effects over the politician’s career.
