This paper outlines two studies on education bias in German probability-based surveys. Study 1 reviews data from 67 surveys across 19 survey programs conducted in Germany from 2000 to 2023. We found a consistent underrepresentation of individuals with a low level of formal education. We also found that the transition to self-administered modes due to rising survey costs may exacerbate this bias in ...

Statement
Vor der polnischen Ostseeküste wurden enorme Öl- und Gasvorkommen gefunden. Das Vorkommen wird aktuell auf 200 Millionen Barrel geschätzt. Über die energiepolitsche Bedeutung einer möglichen Förderung gibt Claudia Kemfert, Leiterin der Abteilung Energie, Verkehr, Umwelt im Deutschen Institut für Wirtschaftsforschung (DIW Berlin) eine Einschätzung:

Using linked data from the Millennium Cohort Study and National Pupil Database (N = 8,139), this study examined how the timing of school absences (years 1 to 11 between 2006 and 2017) affects achievement at the end of compulsory schooling in England. Absences during any school year are harmful to student achievement. However, absences in years 1 and 6 (the final year of primary school), and between ...

DIW Discussion Papers 2127 / 2025
To ensure security of supply in the power sector, many countries are already using or discussing the introduction of capacity mechanisms. Two main types of such mechanisms include capacity markets and capacity reserves. Simultaneously, the expansion of variable renewable energy sources increases the need for power sector flexibility, for which there are promising yet often under-utilized options on ...

We propose a novel method to detect and disentangle moderate and severe health shocks in a general population survey based on a data-driven classification of sickness absences and hospitalizations. Both types of shocks are widespread with an annual incidence of about 1.7%, which rises steeply with age. We estimate the effects of both shocks on labor market outcomes and find that severe shocks have ...

In conventional proxy VAR analysis, the shocks of interest are identified by external instruments. This is typically accomplished by considering the covariance of the instruments and the reduced-form residuals. Alternatively, the instruments may be internalized by augmenting the VAR process by the instruments or proxies. These alternative identification methods are compared and it is shown that the ...

Die Rente muss dringend reformiert werden. Eine Sonderabgabe für Wohlhabende im Ruhestand löst viele Probleme. Ohne die Jüngeren weiter zu belasten. Die Alterung der Gesellschaft und der bevorstehende Ruhestand der Babyboomer-Generation sind kein Zukunftsszenario mehr – sie sind Realität und stellen schon heute eine akute sozialpolitische Herausforderung dar. Der demografische Wandel erschüttert die ...
