The central concern of this paper is to illustrate how certain dimensions of jobs are helpful in determining whether individuals have comparable positions in the work setting. First, the notion of power in the work setting and its relevance to stratification research are discussed. How this conceptualization helps in the understanding of sex differences in job positions is then sketched. Finally, the usefulness of these concepts in clarifying the similarities and differences of positions of men and women in the work setting are demonstrated empirically. The two aspects of power on the job considered are authority and autonomy. The empirical analysis tests whether men and women have differing amounts of authority and autonomy holding constant other relevant variables. These variables include occupational status, education, and self employment. The analysis indicates that sex has a main effect on occupational status level, holding constant the main effects of other variables. It was demonstrated that women are less likely to be in supervisory positions than men. (Author/AM)
