Working Paper
Rural roads and urban agglomeration economies
Do urban agglomeration economies enhance the social profitability of rural roads? When all goods are traded at parametric world prices, lower transport costs benefit villagers. Urban activities and welfare are unaffected if labour is immobile, but...
Working Paper
Industrial agglomeration in Myanmar
Focusing on labour productivity and working conditions, we investigate the benefits of industrial zones for private manufacturing enterprises in Myanmar. We find that being located in an industrial zone associates with higher labour productivity...
Working Paper
Special economic zones in Southern Africa: white elephants or latent drivers of growth and employment?
The successful use of special economic zones as economic tools for export-led industrial development in East Asia propelled a wave of similar initiatives across Africa. In Southern Africa, Zambia and South Africa instituted special economic zones in...
Working Paper
The social profitability of rural roads in a small open economy
In the presence of agglomeration economies, the effects of a rural roads programme depend not only on the reduction in transportation costs, but also on the form of labour mobility. When financed by a poll tax on rural households, the wage will rise...
Journal Article
The social profitability of rural roads in a small open economy
The effects of a rural roads programme depend on labour mobility, how the programme is financed, and agglomera-tion economies. If financed by a rural poll tax and cross-price effects and agglomeration economies are sufficiently small, the wage will...
Research Brief
Spatial dynamics of firm productivity in South Africa
The design and implementation of industrial policy should be closely linked to spatial considerations. Firm output and productivity are often location-specific, with factors such as the availability of physical infrastructure, proximity to sources...
Research Brief
Special economic zones in Zambia and South Africa
East Asia’s successful experience in accelerating the process of industrial development with SEZs paved way for the use of SEZs as policy instruments in Africa. In southern Africa, Zambia and South Africa instituted SEZs in legal and institutional...
Working Paper
Agglomeration and productivity in South Africa
Using comprehensive, anonymized tax administrative data for the 2008–14 period, we examine firm-level productivity in South Africa. Measures of firm-level productivity are included in a spatial autoregressive model that assesses spillovers from total...
Working Paper
Moving up the copper value chain in Southern Africa
Southern African countries—mainly Zambia and the Democratic Republic of the Congo—account for around a seventh of global production of copper. In the 2010s, they imported over a third of the associated capital goods and components from South Africa...
Working Paper
Industrial clusters
Firms tend to cluster in close geographic proximity to each other to benefit from reduced transport costs, shared inputs, and productivity spillovers due to learning and technology transfers. Evidence from low-income countries suggests that such...
