The literature predicts shifts of output and labor first from agriculture to manufacturing, followed by manufacturing to services at later stages of development. This pattern is consistent with the experience of advanced economies that have experienced secular declines in manufacturing employment and sectoral value added since the 1970s. It is also consistent with the experience of East Asian economies whose striking growth performance in recent years has been underpinned by dynamism in manufacturing. However, the recent relatively high-growth episodes in many African economies has been accompanied by a declining share of agriculture and rise in services share, while the manufacturing sector’s share of output has not only remained low but also declining. What are African countries missing? Why this non-conformance with predicted trajectory and trend?
