Guinea and the Ivory Coast are neighbouring, former French colonies in West Africa. Both gained their independence about the same time – Guinea in 1958 and the Ivory Coast in 1960. The contrast in the subsequent economic performance of these two countries with closely corresponding resource endowments is remarkable. The Ivory Coast's gross domestic product has grown at an annual rate of about 8 per cent in real terms. The Guinean economy has stagnated. A review of the economic record of both since independence suggests that three factors were mainly responsible for their strikingly unequal performance: (1) differences in governmental philosophies of mobilisation and organisation of resources; (2) differences in the extent to which foreign markets shaped domestic economic expansion; and (3) differences in the role of foreign entrepreneurs in the national development effort.
