Why does Zimbabwe export manufactures and Uganda not? Econometrics meets history

Uganda and Zimbabwe are predicted on the basis of their human and natural r esources, to have similar shares of manufactures in their exports. However, Uganda falls a long way short of the predicted share, while Zimbabwe great ly exceeds it. Uganda's manufactured export shave is unusually small mainly because of high transport costs, due to its distance from the sea and inad equate infrastructure. Zimbabwe's manufactured export share is unusually bi g mainly because its comparative advantage in manufacturers was enhanced by the know-how brought in by European settlers and a long-term policy of pro moting the sector.
