Intra-household Selection into Migration: Evidence from a Matched Sample of Migrants and Origin Households in Senegal

This paper fills the gap between individual selection models and collective approaches of migration. We build a theoretical model in order to account for household-based migration decisions and derive its implications on migrant selection. Assuming that the origin household maximizes a collective utility including earnings but also further remittances when choosing the one among its members who is to migrate, migrant selection in this case may differ from what is predicted by a pure individual decision model. Therefore, we specifically tackle the so far under-explored issue of intra-household selection into migration in order to identify what are the key determinants of household members' location choices. We derive our estimation procedure from an extension of the Roy-Dahl model and provide empirical evidence using a unique matched sample of 926 Senegalese migrants in three destination countries - France, Italy and Mauritania - and their origin household in Senegal. Our results show that expected remittances, along with earnings differentials, play a major role in shaping intra-household selection patterns, which stands in striking contrast with usual predictions from individual self-selection models.
