International Factor Price Differences: Leontief was Right!
通过修正赫克歇尔-俄林-瓦内克模型，引入要素增强型国际生产率差异，成功解释了贸易的要素含量和各国要素价格差异，实证结果显著。
The factor price equalization hypothesis is widely at odds with the large variation in factor prices across countries. similarly, the Heckscher-Ohlin-Vanek theorem constitutes an incomplete description of trade in factor services: its predictions are always rejected empirically. These two issues are examined using a modification of the Heckscher-Ohlin-Vanek model that allows for factor-augmenting international productivity differences. The empirical results are stark: this simple modification of the Heckscher-Ohlin-Vanek theorem explains much of the factor content of trade and the cross-country variation in factor prices.
