Why Does Zimbabwe Export Manufactures and Uganda Not? Econometrics Meets History
基于人力和自然资源预测，乌干达和津巴布韦的制成品出口份额应相似，但乌干达远低于预测（因高运输成本和基础设施差），津巴布韦远超预测（因欧洲移民带来的技术和长期产业政策）。
Uganda and Zimbabwe are predicted on the basis of their human and natural resources, to have similar shares of manufactures in their exports However, Uganda falls a long way short of the predicted share, while Zimbabwe greatly exceeds it. Uganda's manufactured export share is unusually small mainly because of high transport costs, due to its distance from the sea and inadequate infrastructure. Zimbabwe's manufactured export share is unusually big mainly because its comparative advantage in manufacturing was enhanced by the know-how brought in by European settlers and a long-term policy of promoting the sector.
