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...

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...

Empirical work in labor economics has focused on rent sharing as an explanation for the observed correlation between wages and profitability. The alternative explanation of risk sharing between workers and employers has not been tested. Using a unique panel data set for four African countries,...

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...

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...

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...
