This study investigated how changing the mode of incentive administration between two panel waves, spaced six months apart, affected longitudinal survey response.

An analysis of data from the Socio-Economic Panel (SOEP) shows that more and more refugees from six main countries who came to Germany between 2013 and 2019 were already naturalized or had applied to naturalize. The share of immigrants who had already naturalized increased from 2.1 percent in 2021 to 7.5 percent in ...

The Minorities’ Diminished Returns (MDRs) framework posits that marginalized groups derive weaker health returns from economic resources than majority populations. Extending this framework to a migration context, this study examines wealth - and debt – health gradients ...
