Employment in traditional middle-class jobs has fallen sharply over the last few decades. At the same time, middle-class wages have been stagnant. This column reviews recent research on job polarisation and presents a new study that explicitly links job polarisation with the changes in workers’ wages. Job polarisation has a substantial negative effect on middle-skill workers.
Job polarisation and its cause
Pioneering research by Autor, Katz, and Kearney (2006), Goos and Manning (2007), and Goos, Manning, and Salomons (2009) found that the share of employment in occupations in the middle of the skill distribution has declined rapidly in the US and Europe. At the same time the share of employment at the upper and lower ends of the occupational skill distribution has increased substantially. Goos and Manning termed this phenomenon “job polarisation” and it is depicted for US workers in Figure 1.
