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.

Dual Labor Markets at Work: The Impact of Employers’ Use of Temporary Agency Work on Regular Workers’ Job Stability
in: ILR Review, Nr. 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, Nr. 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, Nr. 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.

Works Councils and Labour Productivity: Looking beyond the Mean
in: British Journal of Industrial Relations, Nr. 2, 2015
Abstract
After more than 25 years of empirical investigation, the analysis of works council effects on establishment productivity is still an active field of economic research. I present first evidence for works council regression coefficients along the unconditional log labour productivity distribution in Germany. The highest (lowest) coefficients were found at the bottom (top) of the distribution, which suggests that works councils have the most beneficial effects at low levels of productivity. Importantly, coefficients are positive at each productivity level. The results shed light on a classical theoretical argument concerning moderating factors for the productivity effect of employee participation.

Safety Net or Helping Hand? The Effect of Job Search Assistance and Compensation on Displaced Workers
in: IWH Discussion Papers, Nr. 18, 2023
Abstract
We provide the first systematic evidence on the effectiveness of a contested policy in Germany to help displaced workers. So-called “transfer companies” (<i>Transfergesellschaften</i>) employ displaced workers for a fixed period, during which time workers are provided with job-search assistance and are paid a wage which is a substantial fraction of their pre-displacement wage. Using rich and accurate data on workers’ employment patterns before and after displacement, we compare the earnings and employment outcomes of displaced workers who entered transfer companies with those that did not. Workers can choose whether or not to accept a position in a transfer company, and therefore we use the availability of a transfer company at the establishment level as an IV in a model of one-sided compliance. Using an event study, we find that workers who enter a transfer company have significantly worse post-displacement outcomes, but we show that this is likely to be the result of negative selection: workers who lack good outside opportunities are more likely to choose to enter the transfer company. In contrast, ITT and IV estimates indicate that the use of a transfer company has a positive and significant effect on employment rates five years after job loss, but no significant effect on earnings. In addition, the transfer company provides significant additional compensation to displaced workers in the first 12 months after job loss.

Committing to Grow: Privatizations and Firm Dynamics in East Germany
in: IWH Discussion Papers, Nr. 17, 2023
Abstract
This paper investigates a unique policy designed to maintain employment during the privatization of East German firms after the fall of the Iron Curtain. The policy required new owners of the firms to commit to employment targets, with penalties for non-compliance. Using a dynamic model, we highlight three channels through which employment targets impact firms: distorted employment decisions, increased productivity, and higher exit rates. Our empirical analysis, using a novel dataset and instrumental variable approach, confirms these findings. We estimate a 22% points higher annual employment growth rate, a 14% points higher annual productivity growth, and a 3.6% points higher probability of exit for firms with binding employment targets. Our calibrated model further demonstrates that without these targets, aggregate employment would have been 15% lower after 10 years. Additionally, an alternative policy of productivity investment subsidies proved costly and less effective in the short term.

Why Is the Roy-Borjas Model Unable to Predict International Migrant Selection on Education? Evidence from Urban and Rural Mexico
in: IWH Discussion Papers, Nr. 16, 2023
Abstract
The Roy-Borjas model predicts that international migrants are less educated than nonmigrants because the returns to education are generally higher in developing (migrant-sending) than in developed (migrant-receiving) countries. However, empirical evidence often shows the opposite. Using the case of Mexico-U.S. migration, we show that this inconsistency between predictions and empirical evidence can be resolved when the human capital of migrants is assessed using a two-dimensional measure of occupational skills rather than by educational attainment. Thus, focusing on a single skill dimension when investigating migrant selection can lead to misleading conclusions about the underlying economic incentives and behavioral models of migration.

Do Role Models Matter in Large Classes? New Evidence on Gender Match Effects in Higher Education
in: IWH Discussion Papers, Nr. 14, 2023
Abstract
It is well established that female students perform better when taught by female professors. However, little is known about the mechanisms explaining these gender match effects. Using administrative records from a German public university, which cover all programs and courses between 2006 and 2018, we show that gender match effects are sizable in smaller classes, but are absent in larger classes. These results suggest that direct and frequent interactions between students and professors are crucial for gender match effects to emerge. In contrast, the mere fact that one’s professor is female is not sufficient to increase performance of female students.

Where Do STEM Graduates Stem from? The Intergenerational Transmission of Comparative Skill Advantages
in: IWH Discussion Papers, Nr. 13, 2023
Abstract
The standard economic model of occupational choice following a basic Roy model emphasizes individual selection and comparative advantage, but the sources of comparative advantage are not well understood. We employ a unique combination of Dutch survey and registry data that links math and language skills across generations and permits analysis of the intergenerational transmission of comparative skill advantages. Exploiting within-family between-subject variation in skills, we show that comparative advantages in math of parents are significantly linked to those of their children. A causal interpretation follows from a novel IV estimation that isolates variation in parent skill advantages due to their teacher and classroom peer quality. Finally, we show the strong influence of family skill transmission on children’s choices of STEM fields.
