Typically, laboratory experiments suffer from homogeneous subject pools and self-selection biases. The usefulness of survey data is limited by measurement error and by the questionability of their behavioural relevance. Here we present a method integrating interactive experiments and...

Pro Jahr verlassen 0,8 Prozent der Bevölkerung Deutschland, das sind etwa 650 000 Personen. Das Medienecho auf diese Auswanderung ist überzogen schrill, denn die meisten Auswanderer haben bereits einen Migrationshintergrund und setzen ihre Migration fort oder kehren in ihre Heimatländer...

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...

This article examines the implications of moving to Computer-Assisted Personal Interviewing (CAPI) for data quality by analyzing the transition from Paper-and-Pencil (PAPI) to Computer-Assisted Personal Interviewing (CAPI) on a subsample of the German Socio-Economic Panel (SOEP) conducted using...

This paper presents two new tools for the identification of faking interviewers in surveys. One method is based on Benford's Law, and the other exploits the empirical observation that fakers most often produce answers with less variability than could be expected from the whole survey. We focus...

Parallel zur Debatte um die demographische Alterung der Gesellschaft - häufig als wachsende "Alterslast" interpretiert - ist in den vergangenen Jahren auch der Bedeutung produktiver Tätigkeitsfelder älterer Menschen nach ihrem Ausscheiden aus dem Beruf - und hier insbesondere dem Ehrenamt -...

Mit der Pilotstudie "Leben außerhalb Deutschlands" beschreitet die Längsschnittstudie Sozio-oekonomisches Panel (SOEP) absolutes methodisches Neuland, indem versucht wird, die Adressen ausgewanderte Teilnehmer des deutsche Haushaltspanels SOEP im Ausland zu recherchieren und die Auswanderer...

This paper examines the implication of the move to CAPI for data quality by analyzing the conversion from PAPI to CAPI of a subsample of the German Socio-Economic Panel (SOEP) which was done within an experimental design. The 2000 addresses for the sample E of SOEP were split into two subsamples...
