The Berlin Aging Study II (BASE-II) is a multidisciplinary study that allows for the investigation of how a multitude of health status factors as well as many other social and economic outcomes interplay. The sample consists of 1,600 participants aged 60 to 80, and 600 participants aged 20 to...

The results of a resurvey of non-respondents to the SOEP study carried out in 2006 show that this special effort of reinterviewing was relatively ineffective in two respects. First, the rate of successful conversions of passive to active respondents was low (less than 20 percent). Second, the...

Using data from the German Socio-Economic Panel (N = 13,145), we investigate the effects of (not) achieving aspirations on subjective well-being. We match individual-level data about life satisfaction aspirations with their subsequent realizations and we jointly estimate two panel-data...

We investigate how worries in Germany change across time and age, drawing on both closed-ended questions (which typically list a number of worry items) and open-ended questions answered in text format. We find that relevant world events influence worries. For example, worries about peace peaked...

Due to its extraordinary explanatory power for individual behavior, the interest in the concept of locus of control (LOC) has increased substantially within applied economic research. But, even though LOC has been found to affect economic behavior in many ways, the reliability of these findings...

Arbeitszeitwünsche von Beschäftigten rücken in der jüngsten Vergangenheit stärker in den Fokus der öffentlichen und wissenschaftlichen Debatte. Dabei kommen repräsentative Studien für Deutschland hinsichtlich der Frage von Über- und Unterbeschäftigung zu sehr unterschiedlichen bis...

Im fünften Armuts- und Reichtumsbericht der Bundesregierung wurde darauf hingewiesen, dass die Datenlage im Bereich hoher Vermögen unzureichend sei (BMAS, 2017). Zur Verbesserung der Datenlage haben wir eine neue Sampling-Strategie entwickelt und im Feld implementiert. In der gezogenen...

We have developed and implemented a new sampling strategy to better represent very wealthy individuals in the German Socio-Economic Panel (SOEP). Our strategy is based on the empirical regularity that the very wealthy have at least part of their assets invested in businesses, and that businesses...

In der vorliegenden Studie wird untersucht, inwiefern sich der Einsatz eines spezifischen Zeitfensters bei Survey-Abfragen zum ehrenamtlichen und freiwilligen Engagement - im Vergleich zu Survey-Abfragen mit unspezifischen Zeitfenstern - auf die Selbstangaben von Befragten auswirkt. Die...

We study response behavior in surveys and show how the explanatory power of selfreports can be improved. First, we develop a choice model of survey response behavior under the assumption that the respondent has imperfect self-knowledge about her individual characteristics. In panel data, the...
