Technological Innovations, Capital Mobility, and the Product Cycle inNorth-South Trade
构建了一个南北贸易的一般均衡模型，北方持续引入新产品，技术扩散速度取决于两地生产成本差异。模型发现南方劳动力增长短期内提高北方实际工资，但长期通过加速技术转移和资本外流降低北方工资。
This paper constructs a general equilibrium model of North-South tradein which the North continually introduces new goods. The rate at whichtechnology diffuses to the South is a function of differences in the cost of production in the two regions. The key result of the model is that labor force growth in the South initially increases real wages inthe North (a standard result in classical trade models), but in the long run reduces Northern wages by accelerating the transfer of technology and drawing capital out of the North as well.
