WEST AFRICAN URBANIZATION: WHERE TOLLEY'S MODEL FAILS

Abstract
The purpose of this paper is to investigate urbanization in West Africa using a model proposed by Tolley. Pribadi and Berry developed this model, then successfully tested it on Indonesia. Our analysis shows the model fails to explain West African urbanization when applied to individual nations. The performance of the model improves when applied on a regional scale, because at this scale migration is internalized. Despite the improved fit, much of the rapid urbanization in some nations remains unexplained by the model, suggesting the importance of other incentives, such as the pull of primate cities and the push from drought and changing environmental conditions.
