Sex Differences in the Supplemental Earnings of College and University Faculty

Data from the 1993 National Study of Postsecondary Faculty are used to examine the characteristics of faculty who supplement their base institutional salaries with various other types of income, as well as the extent to which the likelihood of receiving various types of supplemental income, and the amount of various types of supplemental income received, vary between women and men after controlling for differences in human capital and structural characteristics. Descriptive, logistic regression, and ordinary least squares regression analyses are used to address the research questions.
