Betriebliche Dynamiken und Beschäftigungsergebnisse
Firmengründungen und -schließungen sind in einer Marktwirtschaft für die Reallokation von Ressourcen, strukturellen Wandel und damit für die wirtschaftliche Entwicklung von zentraler Bedeutung und spielen vor allem im Hinblick auf die wirtschaftliche Transformation Ostdeutschlands eine zentrale Rolle. Gleichzeitig können die mit dem Strukturwandel verbundenen Arbeitsplatzverluste dramatische Folgen für betroffene Arbeitnehmer haben, wie z.B. Arbeitslosigkeit, Einkommensverluste oder eine geringere Arbeitsplatzqualität. Diese Forschungsgruppe untersucht mithilfe mikroökonometrischer Methoden Gründungen, Wachstumsprozesse und das Scheitern von Unternehmen, die Anzahl und Qualität der von Neugründungen geschaffenen Arbeitsplätze und die Folgen von Firmenschließungen für betroffene Arbeitnehmer und Arbeitnehmerinnen, vor allem in Bezug auf Arbeitsmarktergebnisse wie Beschäftigung und Löhne.

Firmenlohndifferentiale in unvollkommenen Arbeitsmärkten: Die Rolle von Marktmacht und industriellen Beziehungen in der Aufteilung der Beschäftigungsrenten zwischen Arbeitnehmern und Arbeitgebern
Deutsche Forschungsgemeinschaft (DFG)
Ziel dieses Projekts ist es, die Aufteilung der Beschäftigungsrenten auf unvollkommenen Arbeitsmärkten und den Einfluss von Arbeitsmarktinstitutionen wie Tarifbindung und betrieblicher Mitbestimmung auf Firmenlohndifferentiale zu untersuchen. Über die Grundlagenforschung hinaus hat das Projekt damit Potential, wichtige wirtschaftspolitische Debatten zur institutionellen Ausgestaltung des Lohnfindungsprozesses zu informieren.

Lohn- und Beschäftigungseffekte von Insolvenzen
Deutsche Forschungsgemeinschaft (DFG)
Ziel des Projekts ist es, erstmals den Prozess und die Folgen des Scheiterns von Unternehmen ausführlich zu analysieren. Insbesondere ist es im Rahmen dieses Projekts erstmals möglich, die Folgen kleinbetrieblicher Insolvenzen zu erforschen, was vor allem deshalb relevant ist, weil Arbeitnehmer in Betrieben mit weniger als zehn Beschäftigten etwa viermal so häufig von Insolvenzen betroffen sind wie Arbeitnehmer in Großbetrieben.

Coming to Work While Sick: An Economic Theory of Presenteeism With an Application to German Data
in: Oxford Economic Papers, Nr. 4, 2017
Abstract
Presenteeism, i.e. attending work while sick, is widespread and associated with significant costs. Still, economic analyses of this phenomenon are rare. In a theoretical model, we show that presenteeism arises due to differences between workers in (healthrelated) disutility from workplace attendance. As these differences are unobservable by employers, they set wages that incentivise sick workers to attend work. Using a large representative German data set, we test several hypotheses derived from our model. In line with our predictions, we find that bad health status and stressful working conditions are positively related to presenteeism. Better dismissal protection, captured by higher tenure, is associated with slightly fewer presenteeism days, whereas the role of productivity and skills is inconclusive.

Betriebsräte und andere Formen der betrieblichen Mitarbeitervertretung – Substitute oder Komplemente?
in: Industrielle Beziehungen, Nr. 3, 2017
Abstract
Der Beitrag untersucht anhand des IAB-Betriebspanels (2004-2013) die Verbreitung, Entwicklung und Interdependenz von Betriebsräten und anderen, meist betriebsinitiierten Formen der Mitarbeitervertretung (wie z.B. Runde Tische). In der Privatwirtschaft sind Betriebsräte gleich häufig zu finden wie andere Mitarbeitervertretungen, doch kommt eine gleichzeitige Existenz beider Gremien in einem Betrieb kaum vor. Ökonometrische Analysen mit rekursiven Probit-Modellen verdeutlichen, dass z.T. unterschiedliche Faktoren das Vorhandensein dieser alternativen Formen der Mitarbeitervertretung erklären und dass bezüglich ihrer Existenz, Gründung und Auflösung Betriebsräte und andere Mitarbeitervertretungen negativ miteinander korrelieren. Dies deutet darauf hin, dass zwischen beiden Formen der Arbeitnehmerpartizipation eine überwiegend substitutive Beziehung besteht.

The Dynamic Effects of Works Councils on Labour Productivity: First Evidence from Panel Data
in: British Journal of Industrial Relations, Nr. 2, 2017
Abstract
We estimate dynamic effects of works councils on labour productivity using newly available information from West German establishment panel data. Conditioning on plant fixed effects and control variables, we find negative productivity effects during the first five years after council introduction but a steady and substantial increase in the councils’ productivity effect thereafter. Our findings support a causal interpretation for the positive correlation between council existence and plant productivity that has been frequently reported in previous studies.

Transferability of Skills across Sectors and Heterogeneous Displacement Costs
in: American Economic Review: Papers and Proceedings, Nr. 5, 2017
Abstract
We use rich German administrative data to estimate new measures of skill transferability between manufacturing and other sectors. These measures capture the value of workers' human capital when applied in different sectors and are directly related to workers' displacement costs. We estimate these transferability measures using a selection correction model, which addresses workers' endogenous mobility, and a novel selection instrument based on the social network of workers. Our results indicate substantial heterogeneity in how workers can transfer their skills when they move across sectors, which implies heterogeneous displacement costs that depend on the sector to which workers reallocate.

Skills, Earnings, and Employment: Exploring Causality in the Estimation of Returns to Skills
in: Large-scale Assessments in Education, Nr. 12, 2017
Abstract
Ample evidence indicates that a person’s human capital is important for success on the labor market in terms of both wages and employment prospects. However, unlike the efforts to identify the impact of school attainment on labor-market outcomes, the literature on returns to cognitive skills has not yet provided convincing evidence that the estimated returns can be causally interpreted. Using the PIAAC Survey of Adult Skills, this paper explores several approaches that aim to address potential threats to causal identification of returns to skills, in terms of both higher wages and better employment chances. We address measurement error by exploiting the fact that PIAAC measures skills in several domains. Furthermore, we estimate instrumental-variable models that use skill variation stemming from school attainment and parental education to circumvent reverse causation. Results show a strikingly similar pattern across the diverse set of countries in our sample. In fact, the instrumental-variable estimates are consistently larger than those found in standard least-squares estimations. The same is true in two “natural experiments,” one of which exploits variation in skills from changes in compulsory-schooling laws across U.S. states. The other one identifies technologically induced variation in broadband Internet availability that gives rise to variation in ICT skills across German municipalities. Together, the results suggest that least-squares estimates may provide a lower bound of the true returns to skills in the labor market.

Discrimination on the Child Care Market: A Nationwide Field Experiment?
in: IWH Discussion Papers, Nr. 12, 2023
Abstract
We provide the first causal evidence of discrimination against migrants seeking child care. We send emails from fictitious parents to > 18,000 early child care centers across Germany, asking if there is a slot available and how to apply. Randomly varying names to signal migration background, we find that migrants receive 4.4 percentage points fewer responses. Responses to migrants also contain substantially fewer slot offers, are shorter, and less encouraging. Exploring channels, discrimination against migrants does not differ by the perceived educational background of the email sender. However, it does differ by regional characteristics, being stronger in areas with lower shares of migrants in child care, higher right-wing vote shares, and lower financial resources. Discrimination on the child care market likely perpetuates existing inequalities of opportunities for disadvantaged children.

Skill Mismatch and the Costs of Job Displacement
in: IWH Discussion Papers, Nr. 11, 2023
Abstract
When workers are displaced from their jobs in mass layoffs or firm closures, they experience lasting adverse labor market consequences. We study how these consequences vary with the amount of skill mismatch that workers experience when returning to the labor market. Using novel measures of skill redundancy and skill shortage, we analyze individuals‘ work histories in Germany between 1975 and 2010. We estimate difference-in-differences models, using a sample in which we match displaced workers to statistically similar non-displaced workers. We find that displacements increase the probability of occupational change eleven fold, and that the type of skill mismatch after displacement is strongly associated with the magnitude of post-displacement earnings losses. Whereas skill shortages are associated with relatively quick returns to the counterfactual earnings trajectories that displaced workers would have experienced absent displacement, skill redundancy sets displaced workers on paths with permanently lower earnings.

The Value of Early-Career Skills
in: CESifo Working Paper, Nr. 10288, 2023
Abstract
We develop novel measures of early-career skills that are more detailed, comprehensive, and labor-market-relevant than existing skill proxies. We exploit that skill requirements of apprenticeships in Germany are codified in state-approved, nationally standardized apprenticeship plans. These plans provide more than 13,000 different skills and the exact duration of learning each skill. Following workers over their careers in administrative data, we find that cognitive, social, and digital skills acquired during apprenticeship are highly – yet differently – rewarded. We also document rising returns to digital and social skills since the 1990s, with a more moderate increase in returns to cognitive skills.

Oxytocin, Empathy, Altruism and Charitable Giving: Experimental Evidence from Blood Donations
in: IWH Discussion Papers, Nr. 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.

Early Child Care and Labor Supply of Lower-SES Mothers: A Randomized Controlled Trial
in: CESifo Working Paper, Nr. 10178, 2022
Abstract
We present experimental evidence that enabling access to universal early child care for families with lower socioeconomic status (SES) increases maternal labor supply. Our intervention provides families with customized help for child care applications, resulting in a large increase in enrollment among lower-SES families. The treatment increases lower-SES mothers' full-time employment rates by 9 percentage points (+160%), household income by 10%, and mothers' earnings by 22%. The effect on full-time employment is largely driven by increased care hours provided by child care centers and fathers. Overall, the treatment substantially improves intra-household gender equality in terms of child care duties and earnings.
