Research in the mid 1900s suggested that salary gaps existed between men and women in academia. Though the research helped bring attention to salary gaps, less focus was on causes of salary differences. More recent research suggested differences in salaries were based on performance. A survey was sent to agricultural economics professionals at land grant intuitions to identify the factors that influence their salaries. Results of the ordered probit model suggest that seven variables can be used to explain salaries: having attained tenure, working at an 1862 institution, the amount of grant dollars, the number of journal articles, highest academic rank and the percentage of appointment that is in administration (positive influences) and importance of family time (negative influence). Other variables tested – gender, ethnicity and other preferences – were not found to influence salary levels.
