The paper gives an overview of two experiments implemented in the German Socio-Economic Panel (SOEP) considering the effect of monetary incentives on cross-sectional and longitudinal response propensities. We conclude that the overall effects of monetary incentives on response rates are positive...

Like many medical studies, the Berlin Aging Study II (BASE-II) is based on a non-random convenience sample of self-recruited participants. To study processes of selectivity in BASE-II, we used an identical questionnaire to compare BASE-II with a large, representative reference study, the German...

Web-based interviewing is gradually replacing traditional modes of data collection, in particular telephone and mailed surveys. This global trend takes place despite the fact that established knowledge of its consequences on response error is incomplete. This paper studies differences between a...

In this paper we discuss the rationale for tracing non-original sample members (Non-OSMs) in household panel studies, and in particular in SOEP, and the implications for weighting. We present results on the incidence, survival rates, and thus the relevance of Non-OSMs in the SOEP

Using a research design that traces siblings preferences for postmaterialistic values in Germany over two decades, this paper provides new evidence on the origins of value preferences. Focusing on Inglehart's thesis of value change, we test the combined socialization and scarcity hypothesis...

The computation of cross sectional weights in household panels is challenging because household compositions change over time. Sampling probabilities of new household entrants are generally not known and assigning them zero weight is not satisfying. Two common approaches to cross sectional...

In household panels, typically all household members are surveyed. Because household composition changes over time, so-called following rules are implemented to decide whether to continue surveying household members who leave the household (e.g. former spouses/partners, grown children) in...

Die Armutsgefährdungsquote von Menschen mit Migrationshintergrund liegt im Zeitraum 1995 bis 2015 deutlich über der von Personen ohne Migrationshintergrund. Im Berichtsjahr 2013 ist sie mit 26 % mehr doppelt so hoch wie die von Personen ohne Migrationshintergrund mit 12%.

High-worth individuals are typically underrepresented or completely missing in population surveys. The lack of a register-based sampling frame on high-worth individuals in many countries challenged previous attempts to sample high-worth individuals in voluntary scientific surveys. In a novel...

Das Ausmaß der Vermögenskonzentration in Deutschland lässt sich aufgrund der stark eingeschränkten Datenlage zu hohen Vermögen kaum abschätzen. Dementsprechend sieht auch der fünfte Armuts- und Reichtumsbericht der Bundesregierung weiteren Bedarf, die Datenlage in diesem Bereich zu...
