This paper investigates the existence of local externalities in manufacturing. In contrast to many other studies that focus on aggregate employment growth, we examine the effect of externalities occur through both productivity and wage effects, returns to specialisation are strong and large in...

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...

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...

This paper examines the contractual practices of African manufacturing firms using survey data collected in Burundi, Cameroon, Ghana, Ivory Coast, Kenya, Zambia and Zimbabwe. Descriptive statistics and econometric results are presented. They show that contractual flexibility is pervasive and...

This paper examines the contractual practices of African manufacturing firms using survey data collected in Burundi, Cameroon, Côte d’Ivoire, Kenya, Zambia, and Zimbabwe. Descriptive statistics and econometric results are presented. They show that contractual flexibility is pervasive and that...

This paper tests two alternative models of learning to export: productivity learning, whereby firms learn to reduce production costs, and market learning, whereby firms learn to design products that appeal to foreign consumers. Using panel and cross-section data on Moroccan manufacturers, we...
