from Part II - What Has Changed?
Published online by Cambridge University Press: 02 April 2020
The job structure has become more polarized in recent decades in the United States. Automation and related computerized technologies replaced many jobs which are characterized by well-defined, routine activities that do not require complex analytical skills. Using recent data for the labor force, we find that job polarization increased through about 2011. This overall trend was the outcome of two contrary patterns including occupational downgrading among men and occupational upgrading among women. However, the perception of job polarization may be greater than its actuality because the distribution of household income has become more unequal than the occupational structure due to rising assortative mating. Job polarization seems to have tapered off since 2011 whereas household income inequality has continued to increase. The trend towards job polarization ironically occurred while the educational distribution of workers was becoming less polarized.
