Learning; Earning in Africa: Where are the Returns to Education High?
AbstractThis paper investigates the role of learning - through formal schooling and time spent in the labor market - in explaining labor market outcomes of urban workers in Ghana and Tanzania.� We investigate these issues using a new data set measuring incomes of both formal sector wage workers and the self-employed in the informal sector.� In both countries we find significant, convex returns to education and large earnings differentials between sectors when we pool the data and do not control for selection.� In Ghana there is a particularly steep age-earnings profile.� We investigate how far a Harris-Todaro model of market segmentation or a Roy model of selection can explain the patterns oberved in the data.� We find highly significant differences across occupations and important effects from selection in both countries.� The data is consistent with a pattern by which higher ability individuals queue for the high wage formal sector jobs such that the age earnings profile is convex for the self-employed in Ghana once we control for selection.� The returns to education are far higher in the large firm sector than in others and in this sector they are linear not convex.� In both countries there is clear evidence of convexity in the returns to education for the self-employed and here the average returns are low.
