我的文件，就业份额的变化和职业的工资增长往往会增加单调的各种措施的技能密集度自1980年以来在美国，在现有的解释劳动力市场极化沿着职业工资。这一观察结果并不特别受到特定年代、性别、年龄组或职业分类的影响。证据表明，工资的两极分化并不意味着具有跨职业可比性的技能的两极分化。1980年，由于工资与可观察到的技能结构之间的弱联系，特别是在低工资工作中，技能偏好和两极分化的职业需求并存。本文的实证研究结果可以调和在一个扩展版本的典型技能偏向的技术变革模型，其中包括许多职业和职业内的异质性的技能类型。
I document that employment share change and wage growth of occupations tend to increase monotonically with various measures of skill intensity since 1980 in the US, in contrast to the existing interpretation of labor market polarization along occupational wages. The observation is not particularly driven by a specific decade, gender, age group, or occupation classification. The evidence suggests that polarization by wages does not imply polarization of skills that have cross-occupation comparability. Skill-biased and polarizing occupation demand coexist as a result of the weak connection of wage and observable skill structure particularly among the low-wage jobs in the 1980. The empirical findings of the paper can be reconciled in an extended version of the canonical skill-biased technical change model which incorporates many occupations and within-occupation heterogeneity of skill types.
