Abstract
This paper examines how firms’ exposure to supply chain disruptions (SCD) affects firm outcomes in the European Union (EU). Exploiting heterogeneous responses to workplace closures imposed by sourcing countries during the pandemic as a shock to SCD, we provide empirical evidence that firms in industries relying more heavily on foreign inputs experience a significant decline in sales compared to other firms. We document that external finance, particularly bank financing, plays a critical role in mitigating the effects of SCD. Furthermore, we highlight the unique importance of bank loans for small and solvent firms. Our findings also indicate that highly diversified firms and those sourcing inputs from less distant partners are less vulnerable to SCD.

Wie Arbeitsplatzzusagen die Unternehmensdynamiken beeinflussen

Abstract
Arbeitsplatzzusagen stellen eine häufig genutzte industriepolitische Maßnahme dar. Die zugrundeliegende Studie evaluiert die Wirkungen von Arbeitsplatzzusagen zum Zeitpunkt der Privatisierung der Unternehmen in Ostdeutschland nach der Wiedervereinigung. Diese industriepolitische Maßnahme verlangte von den neuen Eigentümern der Unternehmen, sich zu Beschäftigungszielen zu verpflichten, wobei Strafen für Nichteinhaltung vertraglich vereinbart waren. Die Studie zeigt, dass Arbeitsplatzzusagen zu einer Polarisierung und Fehlallokation führen. Während Unternehmen mit geringer Produktivität aus dem Markt gedrängt werden, führt das industriepolitische Instrument zu Verzerrungen in der Unternehmensgröße. Um diese Verzerrungen abzubauen, haben Unternehmen einen Anreiz, in Produktivität zu investieren. Im Vergleich mit produktivitätssteigernden Subventionen zeigen sich Arbeitsplatzzusagen langfristig als weniger nachhaltig und generieren geringere Beschäftigungseffekte.

Robots, Occupations, and Worker Age: A Production-unit Analysis of Employment

Abstract
We analyse the impact of robot adoption on employment composition using novel micro data on robot use in German manufacturing plants linked with social security records and data on job tasks. Our task-based model predicts more favourable employment effects for the least routine-task intensive occupations and for young workers, with the latter being better at adapting to change. An event-study analysis of robot adoption confirms both predictions. We do not find adverse employment effects for any occupational or age group, but churning among low-skilled workers rises sharply. We conclude that the displacement effect of robots is occupation biased but age neutral, whereas the reinstatement effect is age biased and benefits young workers most.

Organized Labor, Labor Market Imperfections, and Employer Wage Premia
Sabien Dobbelaere, Boris Hirsch, Steffen Müller, Georg Neuschäffer
ILR Review,
No. 3,
2024
Abstract
This article examines how collective bargaining through unions and workplace codetermination through works councils relate to labor market imperfections and how labor market imperfections relate to employer wage premia. Based on representative German plant data for the years 1999-2016, the authors document that 70% of employers pay wages below the marginal revenue product of labor and 30% pay wages above that level. Findings further show that the prevalence of wage markdowns is significantly smaller when organized labor is present, and that the ratio of wages to the marginal revenue product of labor is significantly larger. Finally, the authors document a close link between labor market imperfections and mean employer wage premia, that is, wage differences between employers corrected for worker sorting.

Microdata for Economic Research in Europe: Challenges and Proposals

CEPR,
No. 18640,
2023
Abstract
While access to high-quality microdata is essential for economic research and policy evaluation, effective access to such data remains limited in Europe. It varies from country to country, with uneven information on access procedures. This is a major obstacle to social science research, including research on European competitiveness and the effects of climate change, inequality, globalization, and digitalization. The objective of this paper, which is based on a brainstorming exercise coordinated by CEPR and CompNet, is to assess the status quo and discuss a series of proposals for improving access to Microdata for economic research. We underline the need for developing the relevant tools for extended access to and use of European business statistics microdata. Building such tools entails both establishing the requested microdata and creating a body facilitating cross-country access to the established databases with harmonized content.
