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...

This paper examines the relationship between teacher unionization, student achievement and teachers' pay using a cross-section of data from private schools in India. We use differences in student mark across subjects to identify within-pupil variation in achievement and find that union...

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...

We find that heterogeneity in production functions is an important source of variation in firm outcomes in Africa, and we find it is more important than education or productivity in explaining differences in output per worker. There is some technological diversity within Africa, with more...

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 is 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...

The removal of high levels of protection combined with substantial real devaluations has changed the environment in which Ghanaian manufacturing firms have operated in the 1990s. The changes in output, composition and productivity, which have occurred over this period, are examined in this...
