本文提供了一个模型，企业决定创造什么类型的工作，然后寻找合适的工人。当技术工人很少且技术工人和非技术工人之间的生产率差距很小时，公司会创造单一类型的工作并招募所有工人。技术工人比例的增加或偏向技能的技术变革可以使工作岗位的构成发生质的变化，从而增加对技能的需求、工资不平等和两个群体的失业率。该论文提供了一些证据，表明过去二十年美国的就业构成发生了变化。
This paper offers a model where firms decide what types of jobs to create and then search for suitable workers. When there are few skilled workers and the productivity gap between the skilled and the unskilled is small, firms create a single type of job and recruit all workers. An increase in the proportion of skilled workers or skill-biased technical change can create a qualitative change in the composition of jobs, increasing the demand for skills, wage inequality, and the unemployment rates for both groups. The paper provides some evidence that there has been a change in the composition of jobs in the U.S. during the past two decades.
