Firm Dynamics and Employment Outcomes
In a market economy, firm foundations and closures are important drivers of resource (re)allocation, structural change, and economic development which is particularly important with respect to the economic transformation of East Germany from a state-directed to a market economy. At the same time, job displacement coming along with structural change may have serious consequences for affected employees, such as unemployment, earnings losses, or lower job quality in a new job. This research group uses microeconometric methods to analyze foundation, evolution, and failure of firms, the amount and quality of jobs created by new firms and the consequences of firm closures for employees, in particular in terms of labor market outcomes such as employment and wages.

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.

HIP, RIP, and the Robustness of Empirical Earnings Processes
in: Quantitative Economics, No. 3, 2019
Abstract
The dispersion of individual returns to experience, often referred to as heterogeneity of income profiles (HIP), is a key parameter in empirical human capital models, in studies of life‐cycle income inequality, and in heterogeneous agent models of life‐cycle labor market dynamics. It is commonly estimated from age variation in the covariance structure of earnings. In this study, I show that this approach is invalid and tends to deliver estimates of HIP that are biased upward. The reason is that any age variation in covariance structures can be rationalized by age‐dependent heteroscedasticity in the distribution of earnings shocks. Once one models such age effects flexibly the remaining identifying variation for HIP is the shape of the tails of lag profiles. Credible estimation of HIP thus imposes strong demands on the data since one requires many earnings observations per individual and a low rate of sample attrition. To investigate empirically whether the bias in estimates of HIP from omitting age effects is quantitatively important, I thus rely on administrative data from Germany on quarterly earnings that follow workers from labor market entry until 27 years into their career. To strengthen external validity, I focus my analysis on an education group that displays a covariance structure with qualitatively similar properties like its North American counterpart. I find that a HIP model with age effects in transitory, persistent and permanent shocks fits the covariance structure almost perfectly and delivers small and insignificant estimates for the HIP component. In sharp contrast, once I estimate a standard HIP model without age‐effects the estimated slope heterogeneity increases by a factor of thirteen and becomes highly significant, with a dramatic deterioration of model fit. I reach the same conclusions from estimating the two models on a different covariance structure and from conducting a Monte Carlo analysis, suggesting that my quantitative results are not an artifact of one particular sample.

Industrial Relations: Worker Codetermination and Collective Wage Bargaining
in: Jahrbücher für Nationalökonomie und Statistik, No. 1, 2019
Abstract
Trade unions and employers’ associations, collective bargaining, and employee representation at the workplace are the cornerstones of industrial relations systems in many developed countries. Germany stands out as a country with powerful works councils and a high coverage rate of collective bargaining agreements, supported by encompassing interest groups of employees and employers and by the state. The German case and the perceived stability of its industrial relations regime have attracted considerable attention among researchers and politicians, which also has to do with the country’s high productivity, comparably few strikes, and relatively minor employment problems. However, in recent years industrial relations in many countries including Germany have come under pressure and the fact that there is no obvious and clearly superior alternative to the current regime of industrial and labour relations may not be sufficient to guarantee the survival of the present system.

Plant-level Employment Development before Collective Displacements: Comparing Mass Layoffs, Plant Closures and Bankruptcies
in: Applied Economics, No. 50, 2018
Abstract
This article analyzes the development of employment levels and worker flows before bankruptcies, plant closure without bankruptcies and mass layoffs. Utilizing administrative plant-level data for Germany, we find no systematic employment reductions prior to mass layoffs, a strong and long-lasting reduction prior to closures, and a much shorter shadow of death preceding bankruptcies. Employment reductions in closing plants, in contrast to bankruptcies and mass layoffs, do not come along with increased worker flows. These patterns point to an intended and controlled shrinking strategy for closures without bankruptcy and to an unintended collapse for bankruptcies and mass layoffs.

Abstract
The purpose of this paper is to analyze how long-run unemployment of former apprentices depends on the size of their training firm and their ability.

Do Employers Have More Monopsony Power in Slack Labor Markets?
in: ILR Review, No. 3, 2018
Abstract
This article confronts monopsony theory’s predictions regarding workers’ wages with observed wage patterns over the business cycle. Using German administrative data for the years 1985 to 2010 and an estimation framework based on duration models, the authors construct a time series of the labor supply elasticity to the firm and estimate its relationship to the unemployment rate. They find that firms possess more monopsony power during economic downturns. Half of this cyclicality stems from workers’ job separations being less wage driven when unemployment rises, and the other half mirrors that firms find it relatively easier to poach workers. Results show that the cyclicality is more pronounced in tight labor markets with low unemployment, and that the findings are robust to controlling for time-invariant unobserved worker or plant heterogeneity. The authors further document that cyclical changes in workers’ entry wages are of similar magnitude as those predicted under pure monopsonistic wage setting.

Identifying Bankruptcies in German Social Security Data
in: FDZ-Methodenreport, No. 10, 2017
Abstract
Many empirical studies about firm exits point out that it is important to distinguish between different types of closures, e.g., voluntary and involuntary liquidations. This report describes how exits due to bankruptcies can be identified in the German Establishment History Panel (BHP). In contrast to other closures, bankruptcies can be unambiguously regarded as indica-tion for economic failure and can therefore be interpreted as involuntary exits.

Plant-level Employment Development before Collective Displacements: Comparing Mass Layoffs, Plant Closures, and Bankruptcies
in: IWH Discussion Papers, No. 27, 2016
Abstract
To assess to what extent collective job displacements can be regarded as unanticipated exogenous shocks for affected employees, we analyze plant-level employment patterns before bankruptcy, plant closure without bankruptcy, and mass layoff. Utilizing administrative data covering all West German private sector plants, we find no systematic employment reductions prior to mass layoffs, a strong and long-lasting reduction prior to closures, and a much shorter shadow of death preceding bankruptcy. Our analysis of worker flows underlines that bankruptcies seem to struggle for survival while closures follow a shrinking strategy. We conclude that the scope of worker anticipation of upcoming job loss is smallest for mass layoffs and largest for closures without bankruptcy.
