Trade Liberalization and Wage Inequality in Mexico
研究了1985年墨西哥贸易改革对工资不平等的影响，发现关税削减对低技能行业冲击更大，导致技能密集型产品相对价格上升，从而加剧了工资差距。
During the 1980s in Mexico the wage gap between skilled and unskilled workers widened. The authors assess the extent to which this increased wage inequality was associated with Mexico's sweeping trade reform in 1985. Examining data on 2,354 Mexican manufacturing plants for 1984-90 and Mexican Industrial Census data for 1965-88, they find that the reduction in tariff protection in 1985 disproportionately affected low-skilled industries. Goods from that sector, the authors suggest, may have fallen in price because of increased competition from economies with reserves of cheap unskilled labor larger than Mexico's. The consequent increase in the relative price of skill-intensive goods could explain the increase in wage inequality.
