Large national surveys of faculty afford analysts the opportunity to examine differences in faculty salary based on combinations of all three dimensions--gender, race/ethnicity, and marital status--as well as the possible interactive effects among them. In this study, the authors used data from the 1999 National Study of Postsecondary Faculty (NSOPF:99) to examine the different ways in which a faculty member's gender, race/ethnicity, and marital status can interact to influence compensation. They begin by reviewing the literature on the effects of these variables on faculty salaries and then discuss empirical approaches to measuring differences in faculty salary. The authors then provide a description of the data, followed by the results of their analyses. They conclude with some thoughts on the implications of their findings and future directions for research. (Contains 10 notes and 4 tables.)
