Minimum wage levels are rising around the globe. To shed more light on the possible unintended side effects of higher wage floors, we study the impact of a minimum wage introduction on wages and employment in a quasi-experimental setting where the minimum wage is set extraordinarily high during an economic downturn. We identify treatment effects al...
Digital technologies displace labor from routine tasks, raising concerns that labor is racing against the machine. We develop an empirically tractable task-based framework to estimate the aggregate employment effects of routine-replacing technological change (RRTC), along with the labor and product demand channels through which this aggregate effec...
This paper provides new insights into how wages and employment adjust to a minimum wage policy along different wage and skill groups. For this, we exploit a quasi-experimental setting in the 1990s, where a German industry introduced a minimum wage at an extraordinary high level during an economic downturn with falling revenues. We find positive wag...
Zusammenfassung
Durch eine rasant wachsende Rechenleistung können immer mehr Tätigkeiten, die bislang dem Menschen vorbehalten schienen, mittels Maschinen und Algorithmen automatisiert werden. Dieser technologische Wandel hat eine öffentliche Debatte über mögliche Arbeitsplatzverluste und eine drohende Massenarbeitslosigkeit entfacht. Solche Hiobsb...
New digital technologies more and more diffuse into the economy. Due to this digitisation, machines become increasingly able to perform tasks that previously only humans could to. Production processes and organizations are changing, new products, services and business models emerge. These trends have important implications for European labour marke...
A fast-growing literature shows that digital technologies are displacing labor from routine tasks, raising concerns that labor is racing against the machine. We develop a task-based framework to estimate the aggregate labor demand and employment effects of routine-
replacing technological change (RRTC), along with the underlying mechanisms. We show...
Computing power continues to grow at an enormous rate. Simultaneously, more and better data is increasingly available and Machine Learning methods have seen significant breakthroughs in the recent past. All this pushes further the boundary of what machines can do. Nowadays increasingly complex tasks are automatable at a precision which seemed infea...
In light of rapid advances in the fields of Artificial Intelligence (AI) and robotics, many scientists discuss the potentials of new technologies to substitute for human labour. Fuelling the economic debate, various empirical assessments suggest that up to half of all jobs in western industrialized countries are at risk of automation in the next 10...
Regionale Arbeitsmärkte unterscheiden sich erheblich hinsichtlich wesentlicher Kennzahlen wie der Arbeitslosenquote, des Lohnniveaus oder der Beschäftigungsentwicklung. Wegen ihrer Persistenz sind diese Unterschiede von hoher Relevanz für die Politik. Die wirtschaftswissenschaftliche Literatur liefert bereits theoretische Modelle für die Analyse re...
Regional labor markets are characterized by huge disparities of unemployment rates.Models of the New Economic Geography explain how disparities of regional goods markets endogenously arise but usually assume full employment. This paper discusses regional unemployment disparities by introducing a wage curve based on efficiency wages into the New Eco...
Regional labor markets are characterized by huge disparities. The literature on the wage curve argues that there exists a negative relationship between unemployment and wages. However, this literature cannot explain how disparities of these variables between regions endogenously arise. In contrast, the New Economic Geography analyzes how disparitie...
In analyzing the disparities of the regional developments in the volume of employment in Germany, in the recent empirical literature so called shift-share-regression-models are frequently applied. However, these models usually neglect spatial interdependencies, even though such interdependencies are likely to occur on a regional level. Therefore, t...
The German Renewable Energy Law (EEG) has been a very successful instrument in raising the share of the renewable energies that are not yet competitive. However, a detrimental consequence of this policy is that, through specific feed-in tariffs, it hinders the competition among particular renewable energies. Within the framework of the “Lead Study...
Against the background of the current economic research which concentrates particularly on individual and structural factors, this paper examines if and to what extent social norms (in terms of attitudes towards gender roles and work commitment) can make a complementary statement in explaining women's employment status. The impact is presumed to be...
Zusammenfassung Die Renten aus der Gesetzlichen Rentenversicherung werden aufgrund der demografischen Entwicklung sowohl für Männer als auch
für Frauen relativ zu den Erwerbseinkommen sinken. Frauen sind dabei zusätzlich spezifischen Rentenrisiken ausgesetzt. Um
die Unterschiede zukünftig auszugleichen, helfen insbesondere Maßnahmen, die die Verein...
Zusammenfassung
Schweden überwand seine Wirtschaftskrise Mitte der 1990er Jahre mit Reformen in der Arbeitsmarkt- und Tarifpolitik. Welche
Erfahrungen sind aus der Bewältigung der Krise zu ziehen? Wie haben die einzelnen Maßnahmen zusammengewirkt? Welche Bedeutung
hatte dabei die Struktur der Tarifverhandlungen?
Der schwedische Wohlfahrtsstaat wird häufig als gelungene Kombination aus wirtschaftlichem Erfolg und sozialer Gerechtigkeit angesehen. Zu Beginn der 1990er befand sich Schweden jedoch in einer schweren Krise, aus der es sich mittlerweile weitestgehend erholt hat. Seit der Krise wurden einige Reformbemühungen in der Arbeitsmarkt- und Tarifpolitik u...
In Anbetracht der derzeitigen energie- und klimapolitischen Diskussion ist für die Zukunft mit gravierenden Umwälzungen im Energiesektor zu rechnen. Dabei gibt es im Wesentlichen zwei politische Zielsetzungen: Zum Einen gilt es, die klimapolitischen Ziele bei der Reduktion der CO2-Emissionen zu erfüllen, zum Anderen muss weiterhin eine zuverlässige...
