Occupational Skill Mismatch: Differences by Gender and Cohort

The authors deploy a measure of occupational mismatch based on the discrepancy between the portfolio of skills required by an occupation and the array of abilities possessed by the worker for learning those skills. Using data from the Occupational Information Network (O*NET) and the 1979 and 1997 National Longitudinal Survey of Youth (NLSY79 and NLSY97), they report distinct gender differences in match quality and changes in match quality over the course of careers. They also show that a substantial portion of the gender wage gap stems from match quality differences among the college educated. College-educated females show a significantly greater likelihood of mismatch than do males. Moreover, individuals with children and those in more flexible occupations tend to experience a larger degree of mismatch. Cohort effects are also evident in the data: College-educated males of the younger cohort (NLSY97) are worse off in terms of match quality compared to the older cohort (NLSY79), even as the younger cohort of women is doing better on average.
