During Corona, households are saving more – not for fear of unemployment but for lack of spending opportunities
During the Corona crisis, European households increased their savings dramatically. According to an analysis carried out by the Halle Institute for Economic Research (IWH), the increase in savings is largely due to the inability of households to consume in the face of government lockdown measures, rather than other factors such as economic uncertainty. IWH President Reint Gropp therefore sees potential for a significant catch-up effect in consumption as soon as the lockdown is lifted.

Organised Labour, Labour Market Imperfections, and Employer Wage Premia
Sabien Dobbelaer, Boris Hirsch, Steffen Müller, Georg Neuschäffer
Abstract
This paper examines how collective bargaining through unions and workplace co-determination through works councils shape labour market imperfections and how labourmarket imperfections matter for employer wage premia. Based on representative Germanplant data for the years 1999{2016, we document that labour market imperfections arethe norm rather than the exception. Wage mark-downs, that is wages below the marginalrevenue product of labour rooted in employers' monopsony power, are the most prevalentoutcome. We further nd that both types of organised labour are accompanied by asmaller prevalence and intensity of wage mark-downs whereas the opposite holds for wagemark-ups, that is wages above the marginal revenue product of labour rooted in workers'monopoly power. Finally, we document a close link between our production-based labourmarket imperfection measures and employer wage premia. The prevalence and intensityof wage mark-downs are associated with a smaller level and larger dispersion of premiawhereas wage mark-ups are only accompanied by a higher premium level.

Measuring the Indirect Effects of Adverse Employer Behaviour on Worker Productivity – A Field Experiment
Matthias Heinz, Sabrina Jeworrek, Vanessa Mertins, Heiner Schumacher, Matthias Sutter
Economic Journal,
No. 632,
2020
Abstract
We conduct a field experiment to study how worker productivity is affected if employers act adversely towards their co-workers. Our employees work for two shifts in a call centre. In our main treatment, we lay off some workers before the second shift. Compared to two control treatments, we find that the lay-off reduces the productivity of unaffected workers by 12%. We find suggestive evidence that this result is not driven by altered beliefs about the job or the management’s competence, but caused by the workers’ perception of unfair employer behaviour. The latter interpretation is confirmed in a prediction experiment with professional HR managers. Our results suggest that the price for adverse employer behaviour goes well beyond the potential tit for tat of directly affected workers.

Identifying Cooperation for Innovation―a Comparison of Data Sources

No. 6,
2020
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidized collaborative R&D projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers.

Birds, Birds, Birds: Co-worker Similarity, Workplace Diversity and Job Switches
Boris Hirsch, Elke J. Jahn, Thomas Zwick
British Journal of Industrial Relations,
No. 3,
2020
Abstract
We investigate how the demographic composition of the workforce along the sex, nationality, education, age and tenure dimensions affects job switches. Fitting duration models for workers’ job‐to‐job turnover rate that control for workplace fixed effects in a representative sample of large manufacturing plants in Germany during 1975–2016, we find that larger co‐worker similarity in all five dimensions substantially depresses job‐to‐job moves, whereas workplace diversity is of limited importance. In line with conventional wisdom, which has that birds of a feather flock together, our interpretation of the results is that workers prefer having co‐workers of their kind and place less value on diverse workplaces.

Kommentar: Ohne Konsumverzicht keine CO2-Reduktion – auch, wenn man auf Innovation setzt
Oliver Holtemöller
Wirtschaft im Wandel,
No. 2,
2020
Abstract
In der Diskussion über die deutsche Klimapolitik steht häufig die Frage im Mittelpunkt, mit welchen Instrumenten sich eine Reduktion der CO2-Emissionen am wirksamsten erreichen lässt. So werden etwa die Vorund Nachteile von CO2-Steuern im Vergleich zur Versteigerung von CO2-Zertifikaten und die Reihenfolge der Abschaltung von Braunkohlekraftwerken diskutiert. Neben diesen eher mikroökonomischen Aspekten hat die Klimapolitik weitreichende makroökonomische Konsequenzen.

Alterung, Braunkohleausstieg und Klimapaket: Finanzpolitische Konsequenzen in Deutschland bis 2024
Nach der Mittelfristprojektion des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) wird das Wachstum in Deutschland in den Jahren bis 2024 aufgrund der bald sinkenden Erwerbsbevölkerung spürbar zurückgehen. Dies wird sich auch bei den Staatseinnahmen niederschlagen, und strukturschwache Regionen dürften davon besonders stark betroffen sein. Diese regionalen Effekte werden zwar durch Umverteilungsmechanismen abgefedert, aber nicht völlig ausgeglichen. Regionen mit schrumpfender Erwerbsbevölkerung müssen sich auf einen sinkenden finanziellen Spielraum einstellen. Oliver Holtemöller, Leiter der Abteilung Makroökonomik und Vizepräsident des IWH, ergänzt: „Der beschleunigte Braunkohleausstieg wird diesen Prozess verstärken, das Klimapaket der Bundesregierung hat hingegen vergleichsweise geringe Auswirkungen auf die öffentlichen Finanzen.“

Industrial Cores in East Germany and Its Interaction with the Surrounding Territories—Findings from Four Case Studies
Gerhard Heimpold
List Forum für Wirtschafts- und Finanzpolitik,
No. 2,
2019
Abstract
Subject to this article is how four cases of so called industrial cores have developed in East Germany since 1990. Industrial cores represent former state-owned firms which were regarded as economically viable by the Treuhand. But there was no chance to privatize them in the short run. The case studies show the development prior to and after privatization. A special focus is laid on the interaction between the respective firm and its spatial environment. To sum up: All four firms are still existent. They provide competitive goods and services. Nonetheless, the interaction with the surrounding region differs from case to case. There were spin-offs in all cases. Organizational units previously belonging to the former state owned firms were split up, and became independent firms. In addition, new firms were established. Partly the establishment of new firms was supported directly by—de facto—structural policy measures implemented by the core firms. Partly the new establishments were simply cases of co-location resulting from a prospering regional environment. Taking the four cases, urban areas obviously formed a particularly fertile economic environment.
