This paper uses census and household survey data on Cameroon, Ghana, and South Africa to
examine immigration’s impact in the context of a segmented labor market in Sub-Saharan
Africa. We find that immigration affects (i) employment (ii) employment allocation between
informal and formal sectors, and (iii) the type of employment within each sector. The direction
of the impact depends on the degree of complementarity between immigrants and native
workers’ skills. Immigration is found to be productivity-enhancing in the short to near term in
countries where, the degree of complementarity between immigrants and native workers’
skill sets is the highest.
