The authors model the duration of large-scale, violent civil conflicts, applying hazard functions to a comprehensive data set on such conflicts for the period 1960-99. They find that the duration of conflicts is determined by a substantially different set of variables than those that determine...

The duration of large-scale violent civil conflict increases substantially if the society is composed of a few large ethnic groups, if there is extensive forest cover, and if the conflict has commenced since 1980. None of these factors affect the initiation of conflict. And neither the duration...

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...

The connections between transport infrastructure and economic development have been extensively analyzed in previous research, but little is known about the cost of infrastructure investments in poor countries. This paper examines drivers of unit costs of construction and maintenance of...

We use firm-level data for the Ethiopian manufacturing sector matched with commodity- level data on tariffs to examine the effect of trade liberalization on firm performance during the 1997-2005 period. We find relatively large positive effects of tariff reductions on total factor productivity,...

It has been argued that Africa will not be able to export manufactures as it lacks the necessary skills. Without an ability to export there will only be an incentive to invest in the sector if domestic demand grows rapidly. Comparative data for four African countries - the Cameroon, Ghana, Kenya...

We document empirical patterns of correlation in the adoption of technological innovation and contractural practices among manfacturing firms in Ethiopia and Sudan. The analysis is based upon network data indicating whether any two firms in our sample do business with each other, whether they...

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...
