There is a dearth of women in top ranks within the professions and management, and the barriers to women's attaining these top ranks are often referred to as the glass ceiling. In this chapter we shall analyze and compare the glass-ceiling phenomenon in the United States and Sweden. To quantify and analyze this gender rank gap and explain the existence of this glass ceiling, we consider the following questions: What is the effect of gender on the job rank reached? To what extent do other individual factors, such as age, education, work hours, and part- or full-time status, explain the rank reached? And how much of the gender rank gap can be explained by differences between men and women with reference to these other factors? Did the circumstances of women change over the time period studied and, if so, in what way?.
