Abstract
The literature on the effects of seniority on faculty salaries is inconclusive. Moreover, studies using the same linear regression method come to strikingly different conclusions. Some find that the impact of seniority on faculty salaries is positive, while others report a negative effect. This research demonstrates that seniority effects are sensitive to measurement and regression model specification. Particularly, highly correlated independent variables in faculty salary regression models can lead to counterintuitive and incorrect findings about seniority effects. Seniority is best measured as time in rank rather than as years of service.
