Doch zu einer Sanktion konnten sich die EU und auch Deutschland bisher nicht durchringen: ein Embargo auf den Import russischer Energieträger.

This paper investigates the effects of the introduction of a statutory minimum wage in Germany on the wages and employment of migrants. Migrants are an overrepresented group in the low-wage sector and can be expected to particularly benefit from a minimum wage. We combine a “differential trend adjusted difference-in-differences estimator” (DTADD) and descriptive evidence to evaluate the impact of the ...
We extend standard models of work-related training by explicitly incorporating workers’ locus of control into the investment decision through the returns they expect. Our model predicts that higher internal control results in increased take-up of general, but not specific, training. This prediction is empirically validated using data from the German Socioeconomic Panel (SOEP). We provide empirical ...
We investigate the impact of demographic changes on local public services taking the case of water service. We apply a structural production function approach to a large panel of German water utilities between 2003 and 2014. Exploring variation of population density and the population age structure across service areas and over time, we provide evidence that demographics and their changes significantly ...
The advent of cloud computing promises to improve the way firms utilize IT solutions. Firms are expected to replace large and inflexible fixed-cost investments in IT with more targeted variable spending in cloud solutions. In addition, cloud usage is expected to increase the productivity of firms, as it allows them to quickly customize the IT they require to their specific needs. We assess these assertions ...

Adopting the 3-stage CDM model, we explore the link between R&D, innovation, and productivity for different size groups of Greek manufacturing firms during the prolonged crisis. At the first stage, we find that the ...
