Multicountry, Multifactor Tests of the Factor Abundance Theory
利用12种资源和27个国家1967年的贸易数据，检验赫克歇尔-俄林-瓦内克模型的预测，发现贸易揭示要素丰裕度的命题不成立，且模型被允许技术差异和测量误差的弱模型所取代。
The Heckscher-Ohlin-Vanek model predicts relationships among industry input requirements, country resource supplies, and international trade in commodities. These relationships are tested using data on twelve resources, and the trade of twenty-seven countries in 1967. The Heckscher-Ohlin propositions that trade reveals gross and relative factor abundance are not supported by these data. The Heckscher-Ohlin-Vanek equations among input requirements, resource supplies, and trade are also rejected in favor of weaker models that allow technological differences and measurement errors.
