Apprenticeships are the most common form of non-academic training in sub-Saharan Africa. Most apprenticeships are provided by the private sector, for a fee, and lead to self-employment rather than to wage jobs. Where the effects have been measured, they show that earnings are not higher, on...

The labour productivity differentials between manufacturing firms in Ghana and South Korea exceed those implied by macro analysis. Median value-added per employee is nearly 40 times higher in South Korea than Ghana. The most important single factor in explaining this difference is the Mincerian...

Macro analysis of the sources of income differences has produced very different results as to the importance of education. In this paper we investigate the roles of education and technology in explaining differences in firm level productivity across Ghana and South Korea. The labour productivity...

Do openness to trade and higher levels of human capital promote faster productivity growth? That they do is a key implication of several versions of endogenous growth theory. To answer the question we use panel data on 93 countries spanning the 1970-2000 period. Controlling for fixed effects as...

Three dimensions of the performance of firms in Ghana’s manufacturing sector are investigated in this paper: their technology and the importance of technical and allocative efficiency. We show that the diversity of factor choices in not due to a non-homothetic technology. Observable skills are...

The evidence that earnings rise with firm size and that human capital affects earnings based on labour market data are two of the most robust empirical findings in economics. In contrast the evidence for scale economies in firm data is very weak. The limited direct evidence of human capital on...

In this paper two sets of issues are addressed using panel data from the manufacturing sector of five African countries. First, how high are the returns to human relative to physical capital. Second, what is the relative importance of technology and endowments of human and physical capital in...
