斯托尔珀-萨缪尔森定理预测，贸易后美国高技能劳动力的相对工资将上升，而墨西哥则下降，而数据显示，两国的技能溢价在 20 世纪 80 年代开始上升。本文针对这种“工资不平等异常”提出了一种基于贸易的简单解决方案。该决议是众所周知的品种贸易模型的直接应用。产业内贸易增加了高技能密集型最终产品所使用的中间产品的种类。如果品种和高技能是“互补的”，那么两国的技能溢价都会上升。有证据支持产业内贸易与工资不平等之间的联系。
The Stolper-Samuelson theorem predicts the relative wage of high-skilled labor will increase in the U.S. but decrease in Mexico after trade, while data shows the skill premium began to rise in both countries during the 1980s. This paper presents a simple trade-based resolution of this “wage inequality anomaly.” The resolution is a straightforward application of well-known variety trade models. Intra-industry trade increases the variety of intermediate goods used by the high-skill intensive final good. If the varieties and high skill are “complements,” the skill premium rises in both countries. Evidence supports this linking of intra-industry trade to wage inequality.
