New Products and the Factor Content of International Trade
扩展了赫克歇尔-俄林模型，纳入新产品，并重新检验要素丰裕度对贸易中资本和劳动含量的影响，发现新产品在特定条件下可能解释里昂惕夫悖论。
This paper extends the multicommodity two-input version of the Heckscher-Ohlin model to include "new products," on which considerable interest has been focused by the product-cycle hypothesis and related analyses. The extended model is then used to reexamine the implications of relative factor abundance for the capital and labor content of international commodity trade. As this analysis shows, the presence of new products might in principle resolve the Leontief paradox under certain specific conditions.
