Workers and Trade Liberalization: The Impact of Trade Reforms in Mexico on Wages and Employment
利用1986-1990年墨西哥贸易改革期间的微观数据，研究发现保护程度下降越大的行业低技能工人占比越高，贸易改革加剧了工资不平等，进口许可覆盖减少使改革行业相对工资下降2%，但对相对就业无显著影响。
Between 1986 and 1990, the Mexican government reduced tariffs and import license coverage by more than 50%. The author, using micro-level data, analyzes the impact of trade reform on Mexican wages and employment. Industries that had greater reductions in protection levels, she finds, had a larger percentage of low-skill workers. Wage dispersion increased in both the non-tradables sector and, to a much greater degree, the tradables sector. This pattern suggests that trade reform increased wage inequality. The decline in import license coverage appears to have reduced relative wages of workers in reformed industries by 2%, but did not affect relative employment. Reductions in tariffs had no statistically significant effect on relative wages or relative employment.
