We develop a theoretical model regarding the migration of dual-earner couples and test it in the context of international migration. Our model predicts that the probability that a couple emigrates increases with the income of the primary earner, whereas the income of the sec-ondary earner may affect the decision in either direction. We conduct an empirical analysis that uses population-wide administrative data from Denmark, and the results are consistent with our model. We find that primary earners in couples are more strongly self-selected with respect to income than single persons. This novel result counters the intuition that family ties weaken self-selection.
