Intergenerational Transmission of Party Affiliation Within Political Families

We investigate the intergenerational transmission of political-party affiliation within families with at least two politicians. We use Swedish registry data that covers all nominated politicians for the years 1982 to 2014, as well as their family ties. First, we demonstrate there is a strong link between individuals and their parents concerning party affiliation. We also find that this intergenerational transmission persists over generations and across siblings. Our second aim is to investigate the mechanisms behind this result, which we do by first discussing two hypotheses: the one concerns a socialization pathway, the other a materialistic one. We then bring these hypotheses to the data, and we find that the socialization pathway matters more for intergenerational transmission.
