Exports, growth and threshold effects in Africa.

The relationship between openness and growth remains a controversial issue in development economics with many studies focusing on the export–growth relationship. This paper examines whether the relationship between exports and growth found in large cross-section studies also holds in the context of African economies. The paper employs threshold regression techniques to examine whether African countries benefit more from exports when they reach a certain level of development or openness. Our results suggest that there is indeed a positive relationship between exports and growth in Africa. The threshold regression analysis also suggests that it is not necessary for a country to reach a certain level of development or to have an existing export base for this relationship to hold, though it is found that the relationship is stronger for countries that experience higher rates of export growth.
