Abstract

We examine intergenerational income persistence and economic assimilation among immigrant groups, focusing on sibling correlations in permanent earnings. Using Dutch administrative data and a heterogeneous income transmission model, we analyze variations across genders, ethnic backgrounds, and immigrant generations. Our results show that, while sibling correlations in income are similar across groups, the underlying factors differ. Immigrants, especially those of Turkish and Moroccan descent, display distinct intergenerational patterns, indicating slower assimilation. Our results are invariant to adjustments for neighborhood characteristics such as ethnic segregation.
