Equipping the Offline Population with Internet Access in an Online Panel: Does It Make a Difference?

Online panel surveys are often criticized for their inability to cover the offline population, potentially resulting in coverage error. Previous research has demonstrated that non-internet users in fact differ from online individuals on several sociodemographic characteristics. In attempts to reduce coverage error due to missing the offline population, several probability-based online panels equip ...

Chronic Disease Onset and Wellbeing Development: Longitudinal Analysis and the Role of Healthcare Access

Background Experiencing the onset of a chronic disease is a serious health event impacting living conditions and wellbeing. Investigating wellbeing development and its predictors is crucial to understand how individuals adapt to chronic illnesses. This study (i) analyzed the impact of a chronic disease on wellbeing development, and (ii) explored spatial healthcare access as potential moderating factor. ...

The Long Reach of Class Origin on Financial Investments and Net Worth

In this study, we argue that parents’ class position may influence the type and timing of their offspring's investments in financial assets. These investments may facilitate net worth accumulation beyond direct transfers, contributing to the intergenerational reproduction of social positions. We test these expectations using retrospective life history and prospective panel data for 14 countries from ...

Conducting Respondent-Driven Sampling with Ethnic Minority Populations: The State of the Field

Ethnic minorities are often underrepresented in survey research, due to the challenges many researchers face in including these populations. Respondent-driven sampling (RDS) was developed in the late 1990s in order to investigate populations otherwise “hidden” from researchers due to a lack of extant sampling frames. RDS relies on individuals who recruit their fellow population members, allowing samples ...

Kernelemente des Strommarktdesigns – Anforderungen, Ziele, Bewertungskriterien und Handlungsoptionen

1. In der vorliegenden Analyse werden fünf zentrale Herausforderungen für den Strommarkt identifiziert, die den Übergang in ein System mit vollständig klimaneutraler Energieerzeugung maßgeblich beeinflussen: (1) Die Sicherstellung eines hohen Ausbautempos Erneuerbarer Energien, (2) die Einstellung der fossilen Reststromerzeugung, (3) die Sicherstellung der Versorgungssicherheit bei hohen Anteilen Erneuerbarer ...

Impacts of Electric Carsharing on a Power Sector with Variable Renewables

Electrifying the car fleet is a major strategy for mitigating emissions in the transport sector. As electrification cannot solve all negative externalities associated with cars, reducing the size of the car fleet would be beneficial. Electric carsharing could reconcile current car usage habits with a smaller fleet, but this may reduce the potential of electric cars to align their grid interactions ...

#25 Eine Reserve als Feuerwehr für das Stromsystem?

Versorgungssicherheit im Stromsystem ist fundamental, damit wir nicht im Dunkeln sitzen. In der letzten Folge von fossilfrei haben wir verschiedene Optionen vorgestellt, wie man unser Stromsystem absichern kann, das zunehmend auf fluktuierenden erneuerbaren Energien basiert. In dieser Folge geht es im Detail um eine dieser Optionen: die „Versorgungssicherheitsreserve“. Unser Kollege Karsten...

Der Kuchen muss vielleicht gar nicht kleiner werden

Der Streit der Ampel hat das Land gelähmt, Deutschland ist tief gespalten. Doch eine neue Regierung wird die gleichen Konflikte haben. Es gibt aber eine Lösung. Die Hoffnung, dass die neue Bundesregierung die großen Probleme endlich löst, ist naiv. Vier grundlegende Konfliktlinien zwischen den Parteien im Bundestag spiegeln die Spaltung der Gesellschaft wider und werden wohl auch unter einer neuen ...
