The SARS-CoV-2 coronavirus has spread rapidly across Germany. Infections are likely to be under-recorded in the notification data from local health authorities on laboratory-confirmed cases since SARS-CoV-2 infections can proceed with few symptoms and then often remain undetected. Seroepidemiological studies allow the estimation of the proportion in the population that has been infected with SARS-CoV-2 ...

We found that environmental concerns increased modestly from 2009 to 2017. Individuals in middle adulthood tended to be more concerned and showed more consistent increases in concern over time than younger or older ...

In this paper, I analyze how the higher education decision of young adults in Germany depends on their expected future earnings. For this, I estimate a microeconometric model in which individuals maximize life-time utility by choosing whether or not to enter higher education. To forecast individual life cycles in terms of employment, earnings, and family formation under higher education and its alternative, ...

Assessing regional population compositions is an important task in many research fields. Small area estimation with generalized linear mixed models marks a powerful tool for this purpose. However, the method has limitations in practice. When the data are subject to measurement errors, small area models produce inefficient or biased results since they cannot account for data uncertainty. This is particularly ...

This article describes new immigrants’ levels of destination-language proficiency shortly after taking up residence in Germany. The focus lies on a comparison of refugees from Syria with new arrivals from Italy, Poland, and Turkey, who came as economic immigrants, for family reasons, or as students. The theoretical account builds upon a well-established model of language acquisition, according to which ...

We present evidence from a repeated survey on risky asset holdings carried out on a representative sample of the German population six times between April and June 2020. Given the size of the Covid-19 shock, we find little evidence of portfolio rebalancing in April 2020. In May, however, individual investors started buying heavily, fueling market recovery. The cross-section shows large differences ...

It is based on the finding that the digital footprint, especially the Facebook likes, can in part predict the personality of users better than friends and family. The survey was conducted among ...
