This paper looks at earnings differentials between (1) members of different ethnic groups and (2) employers’ relatives, unrelated co-ethnics, and other workers, in the Ghanaian manufacturing sector. We find that a significant proportion of the identified earnings differentials between ethnic...

The authors look at earnings differentials between members of different ethnic groups, and between employers' relatives, unrelated members of the same ethnic group, and other workers in Ghana's manufacturing sector. They find that a significant proportion of the earnings differentials identified...

In Ghana's manufacturing sector, workers tend to be employed by members of their own ethnic group, and different ethnic groups run very different types of enterprises. Employers favor their relatives in pay and in job allocation, possibly because they are more productive. There is no evidence of...

In this paper, we use firm-level panel data for the manufacturing sector in four African countries to estimate the effect of exporting on efficiency. Estimating simultaneously a production function and an export regression that control for unobserved firm effects, we find both significant...

We investigate the question whether firms in the manufacturing sector in Africa are credit constrained. The fact that few firms obtain credit is not sufficient to prove constraints, since certain firms may not have a demand for credit while others may be refused credit as part of profit...

In this paper, we use firm-level panel data for the manufacturing sector in four African countries to estimate the effect of exporting on efficiency. Measures of firm-level efficiency using stochastic production frontier models are constructed for the period 1992 to 1995. We find that there are...

Firm-level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. A positive effect from profits onto investment is identified in a flexible accelerator specification of the investment function controlling for firm fixed effects. There is...
