Intergenerational Transmissions and Sibling Correlations in Extreme Right-Wing Party Affinity and Attitudes towards Immigration$ Alexandra Avdeenko DIW Berlin Thomas Siedler University of Hamburg DIW Berlin University of Essex Abstract Preferences, and in particular political preferences, are influenced by a complex interplay of incentives and processes of socialization. This study analyzes the importance of the family and parental socialization for the development of children’s attitudes towards extreme right-wing parties and immigration. Using rich longitudinal data from the German SocioEconomic Panel, the intergenerational estimates suggest that the strongest and most important predictor for young people’s right-wing extremism are parents’ right-wing extremist attitudes. While intergenerational associations for attitudes towards immigration are equally high for sons and daughters, we find considerable gender differences in the intergenerational transmission of right-wing extremist party affinity. Compared to the intergenerational transmission of other parties, the high association between sons’ and fathers’ right-wing extremist attitudes is particularly striking. Sibling correlations in political preferences also point to the importance of the family for children’s political socialization. $ We gratefully acknowledge funding from the Fritz Thyssen Foundation.
