Allocation of Labor in Urban West Africa:
Insights from the Pattern of Labor Supply and
Skill Premiums
Ralitza Dimova, Christophe J. Nordman, and François Roubaud*
Abstract
Using comparable data from five West African capitals, we assess the rationale behind development policies
targeting high rates of school enrollment through the prism of allocation of labor and earnings effects of skills
across the formal and informal sectors, and not working.We find that people with high levels of education
allocate to the small formal sector, while less educated workers allocate to the informal sector. While high
levels of education are given more value in the relatively smaller sectors of salaried employment, observed
skills like education appear to be fairly unprofitable in the larger self-employment sector. The fact that only
the small formal sector in urban West Africa both seems to absorb highly educated workers and provide high
skill premiums may be an important reason for the observed low demand for education and high dropout
rates.
1. Introduction
Educational investment in general and investment in basic education in particular have
long been among the main targets of both bilateral and multilateral donors. Between
the 1960s and the turn of the twenty-first century, the World Bank, the single largest
donor, doubled its total investment, while the eight largest bilateral donors reached a
contribution of more than US$100 million per annum (EFA Global Monitoring
Report, 2005). As Sub-Saharan Africa has consistently been the primary destination of
educational investment, it is not surprising that gross elementary school enrollment
rates in the subcontinent increased from 40% in the 1960s to 87% in the 1990s, while
gross secondary school enrollment rates rose from 3.4% to 26% over the same period
(World Bank, 2004). Yet, the number of adults without basic literacy increased from
131.4 million in 1990 to 136 million in 2000, more than one in 10 children continued to
repeat at least one grade in more than half of the Sub-Saharan African countries, and
the expected link between increasing levels of educational enrollment and growth
remains as elusive as ever (Pritchett, 2001; UNESCO, 2007).
A plausible, but often ignored, explanation of the above pattern could be either the
low rentability of the available stock of education or low availability of easily attainable
high-skill jobs in the Sub-Saharan African labor market, which decrease both the
individual incentive to acquire education and the association between educational
enrollment and growth. The two strands of literature touching on this issue have failed
to reach a consensus. On the one hand, there has been an ongoing debate on the
appropriate measurement of returns to different types of education (Psacharopoulos
