SARS-CoV-2, the coronavirus, spread across Germany within just a short period of time. Seroepidemiological studies are able to estimate the proportion of the population with antibodies against SARS-CoV-2 infection (seroprevalence) as well as the level of undetected infections, which are not captured in official figures. In the seroepidemiological study Corona Monitoring Nationwide (RKI-SOEP-2), biospecimens ...
Dieser Beitrag erschien im Handelsblatt. Vielen Zentralbanken fehlen die Instrumente, um die Inflation zügig zu senken. Die EZB sollte das zugeben und die Fiskalpolitik in die Pflicht nehmen, meint Marcel Fratzscher. Die Europäische Zentralbank hat gestern nicht nur viele mit einer stärker als erwarteten Erhöhung des Leitzinses überrascht, sondern sie hat in den vergangenen Wochen auch eine gefährliche ...
In this paper we estimate the effect of unemployment on informal care provision. For the identification we use plant closures as a source of exogenous variation and combine difference-in-differences with matching based on entropy balancing. The analysis is based on data from the German Socio-Economic Panel (SOEP). We find that there is a time conflict between employment and informal care provision. ...
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 ...
How does previous exposure to massive immigrant inflows affect concerns about current immigration and the integration of refugees? To answer this question, we investigate attitudes toward newcomers among natives and previous immigrants. In areas that in the 1990s received higher inflows of immigrants of German origin—so-called ethnic Germans—native Germans are more likely to believe that refugees are ...
High growth firms are high on the policy agenda as empirical evidence consistently shows that they disproportionately contribute to economic growth via net job creation. Several innovation scholars analyze how high growth entrepreneurship responds to the local enabling environment, such as institutional and framework conditions. However, the majority of these studies look at the role of formal...
We analyze mergers between strategic data intermediaries collecting consumer information that they sell to firms competing in a product market. We show that a merger: (a) reduces the intensity of competition in the product market through a change in the selling strategies of merging intermediaries; (b) increases data collection, reducing consumer surplus through a better rent extraction. We argue...
