Migration, Self-selection and Returns to Education in the WAEMU

Using data from labour force surveys conducted simultaneously in the capital cities of seven West African Economic and Monetary Union countries, we estimate a model of residential location choice in which expected earnings play a role. The model is first estimated in a reduced form. Estimates are then used to correct for the endogeneity of locational choice in the earnings equations estimated for each country. We find that migration behaviour has a significant effect in shaping earnings differentials between education levels and between the seven capital cities. Corrected predicted earnings in each country are then used as an independent variable in a structural multinomial logit of residential choice. Results show that individuals tend to reside in countries in which their expected earnings are higher than elsewhere.
