All in the family: Self-selection and migration by couples.

This paper examines determinants of couple migration in a model that accounts for self-selection of migrant couples. The study is based on a sample of married couples from the Swedish population. The model incorporates controls for earnings of both spouses preceding the move, and explicitly addresses unmeasured heterogeneity in the family decision to migrate. Two statistical formulations are presented. In the first version, migration is measured as a dichotomous move/stay decision. A second formulation replaces the dichotomous indicator with the distance moved by migrants. Results suggest that family migration is selective of relatively low earning wives with unmeasured potential for strong earnings. [ABSTRACT FROM AUTHOR]
