Abstract
During the last two decades, economic development has been slow in most of the countries of Sub-Saharan Africa (World Bank, 1981). In the middle of the 1970s when the world economy experienced inflation and recession, no where did the crises hit with greater impact than in Sub-Saharan Africa. This region shows slow overall economic growth, sluggish agricultural performance, rapid rates of population increase, and a balance of payment crises. Between 1960 and 1979, per capita income in 19 countries grew by less than 1% per annum. During the last decade 15 countries recorded a negative rate of income growth per capita (World Bank, 1981).The economic state of the oil exporting countries (Angola, Congo and Nigeria) in Sub-Saharan Africa is not any different. The average annual growth rate of GNP per capita from 1960–1979 shows Angola at –2.1%, Congo at 0.9% and Nigeria at 3.7%.
