Are Skill Requirements Rising? Evidence from Production and Clerical Jobs

Abstract

This paper examines changes in skill requirements for production jobs in 93 manufacturing establishments between 1978 and 1986 and clerical jobs in 211 firms between 1978 and 1988. The unique data set allows an analysis not only of changes in the distribution of employment across jobs—the usual approach—but also of changes in skill requirements within job titles. The results suggest that significant upskilling is occurring within most production jobs in manufacturing; shifts in the composition of the work force toward higher-skill production jobs contribute a smaller amount to the overall rise in average skill requirements. Changes in clerical jobs are more complicated and suggest an even split between jobs that were upskilled and those that were deskilled. The development of new office equipment appears to be associated with the deskilling of specific clerical jobs.
