What two kinds of parallel development does Davidson see in the African states?

Davidson identifies two kinds of parallel development in African states: the formal sector, which includes government institutions and established businesses, and the informal sector, which consists of unregulated and often small-scale economic activities. This duality reflects the coexistence of modern economic practices alongside traditional systems, leading to disparities in growth and access to resources. The informal sector often provides vital economic support but lacks the stability and recognition of the formal sector.
