We present quasi-experimental evidence on the employment effects of an unprecedented large increase in the early retirement age (ERA). Raising the ERA has the potential to extend contribution periods and to reduce the number of pension beneficiaries at the same time, if employment exits are successfully delayed. However, workers may not be able to work longer or may choose other social support programs ...
Hannes Ullrich from the department of Firms and Markets was accepted as a member of the Committee on Industrial Economics of the German Economic Association (VfS). With around 4,000 members – both individuals and institutions – the association is one of Europe’s largest associations of economists. 24 committees are responsible for a large part of the research work carried ...
Labor supply in the market for low-paid jobs in Germany is strongly influenced by tax exemptions - even for individuals to whom these exemptions do not apply. We present compelling evidence that an individual's choice set depends on other workers' preferences because firms cater their job offers to aggregate preferences in the market. We estimate an equilibrium job search model which rationalizes the ...
Aktuell besteht eine der zentralen politischen Aufgaben in der Integration von Geflüchteten in die Gesellschaft. Integration setzt sich aus Teilprozessen, wie dem Erlernen der deutschen Sprache oder der Arbeitsmarkteinbindung, zusammen. In diesem Bericht betrachten wir diese Teilprozesse für Geflüchtete, die vor allem zwischen 1990 und 2010, nach Deutschland einreisten.
The emerging literature on power markets with high shares of variable renewable energy sources suggests that the costs of more frequent start-ups of thermal power plants may become an increasing concern. Here we investigate how this develops in Germany, where the share of variable renewables is expected to grow from 14% in 2013 to 34% in 2030. We show that the overall number of start-ups grows by 81%, ...
Is it possible to compress instruction time into fewer school years without lowering education levels? A fundamental reform in Germany reduced the length of academic track schooling by one year, while increasing instruction hours in the remaining school years to provide students with a very similar core curriculum and the same overall instruction time. Using aggregated administrative data on the full ...
Starting from a low level, in recent years the battery-supported self-consumption of solar electricity (solar prosumage) has grown significantly in Germany. Its growth is primarily due to the opposing trends in household electricity prices and feed-in tariffs in conjunction with government incentives for battery storage. Various benefits of solar prosumage speak to its positive potential in the German ...
