For hard-to-survey populations such as ethnic minorities and immigrants, increasing survey response rates is a crucial element of the fieldwork as these populations often show a higher likelihood of not participating compared with the native population. However, no study has so far compared different strategies for mobilisation within this group.…

Panel attrition is a major problem in long-term panel studies. While the design of the German National Educational Panel Study adult survey--combining biannual competency tests with regular face-to-face interviews--is highly innovative, such a design could raise respondent burden and thus potentially increase panel attrition and nonresponse bias.…

To reduce nonresponse bias in surveys, it has been suggested that researchers allocate additional fieldwork efforts to cases with low estimated response propensity. If these efforts are successful, nonresponse bias may be reduced by changing the variance of response propensities and hence the covariance between response propensities and variables…

In this paper, I examine whether generalized trust and education, as well as social security policies of welfare state institutions matter for cross-national differences in subjective well-being (SWB), because knowledge on this issue is still lacking. For this purpose I integrated the insights of two sociological theories: Social Function…

The Teacher Education and Development Study in Mathematics (TEDS-M), conducted under the aegis of the International Association for the Evaluation of Educational Achievement (IEA), was designed to inform policy and practice in mathematics teacher education. For educational policymakers, TEDS-M contributes data on institutional arrangements that…
