TL;DR
This study analyzes how skill requirements in occupations evolve in the information age, revealing that low-skilled jobs face the highest reskilling pressures, especially among small employers, markets, and demographic groups.
Contribution
It introduces a comprehensive analysis of occupational skill change using online job posts, highlighting the greater reskilling needs of low-skilled jobs and demographic disparities.
Findings
Low-skilled occupations experience the greatest skill change when accounting for skill distance.
Jobs in small employers and markets require larger skill upgrades.
Female and minority workers face the most significant skill adjustments.
Abstract
Substantial scholarship has estimated the susceptibility of jobs to automation, but little has examined how job contents evolve in the information age as new technologies substitute for tasks, shifting required skills rather than eliminating entire jobs. Here we explore patterns of occupational skill change and characterize occupations and workers subject to the greatest reskilling requirements. Recent work found that changing skill requirements are greatest for STEM occupations in the 2010s. Nevertheless, analyzing 167 million online job posts covering 727 occupations, we find that skill change is greatest for low-skilled occupations when accounting for distance between skills. We further investigate the differences in skill change across employer and market size, as well as social demographic groups. We find that jobs from small employers and markets experienced larger skill upgrades…
