Was colonization very costly for the metropole? This view has been widely accepted among French historians even though little empirical evidence has been provided. Using original data from the colonial budgets of French West Africa (AOF) this paper provides new insights into the actual colonial...

Since the independences, having a single currency is an official policy objective of West African countries. In April 2000, West African decisions-makers decided to accelerate the integration of the region by creating a second monetary zone in addition to the WAEMU (West African Economic and...

There are continuing efforts at the monetary integration and unionization in West Africa. Several academics argue that a monetary union among West African states would be costly because of the magnitude of asymmetric shocks. A common monetary policy is inappropriate and ineffective to respond to...

The influence of food aid and remittances on West African food import demand is evaluated using a Central Bureau of Statistics (CBS) model. Our results show that imports of oilseeds and the rest of the agricultural products category are highly price elastic, and that fruit and vegetables and...

This paper assesses the potential economic impacts of balanced nutrient management systems technology options: BNMS-manure, which combines inorganic fertilizer and organic manure, and BNMS-rotation, which is maize–soybean rotation, in maize-based systems in the northern Guinea savanna...

Cotton is the largest source of export receipts in several West African nations where yields are declining and pesticide use is rising. Although there may be payoffs to introducing genetically modified Bt (Bacillus thurigiensis) cotton, limited information is available to predict its potential...
