Skills are considered a key determinant of workers’ labor market opportunities, especially in times of rapid technological change. However, existing research rarely conceptualizes and measures skills in their own right, instead relying on occupations as a proxy. How does this limit our understanding of the labor market structure and of wage inequality? In this article, we leverage a unique dataset of millions of online job postings in the United Kingdom to measure the skill profiles of jobs and analyze their similarity within and between occupational categories. Our data-driven approach reveals substantial discrepancies between occupational classifications and the actual skill content of jobs. We further demonstrate that job-level variation in skill content constitutes an independent source of wage inequality—one that is obscured by analyses at the occupational level. These findings challenge the conventional view of occupations as coherent bundles of skills, offering new avenues for analyzing labor market stratification.

Is There a Caring Class? Intergenerational Transmission of Care Work

Maria Charles, Corrie Ellis, Paula England

Sociological Science, September 30, 2015
DOI 10.15195/v2.a25

Most research on intergenerational social reproduction has been concerned with upward and downward movements across rank-ordered, “big-class” categories or along continuous gradients of status, income, or skill. An exception is the more nominal conceptualization of the social structure offered in recent research that focuses on qualitative differences in life conditions across occupational “micro classes.” The present analysis broadens this nominal approach by considering social reproduction across an important qualitative dimension that bridges multiple occupations: whether or not one’s work centrally involves care. Based on data from the U.S. General Social Surveys, results provide little evidence that care work is transmitted from parents to children. While women and men whose parents worked in care are more likely to do so themselves, this association is attributable to a general tendency for people to work in the same detailed occupation as their parents. Parents pass along their vertical status positions, and sometimes their specific occupations, but not care work as such. Parent–child similarity in caring outcomes likely reflects transmission of values, skills, knowledge, and network ties that are specific to detailed occupations, rather than attributable to care work broadly defined.
