The use of a parity-equity model to evaluate faculty salary policies

A parity-equity model was developed for estimating the influences of a comprehensive list of factors classified as rational or nonrational equity and parity (marketplace). In a multiple regression analysis of faculty salaries for two years, the parity-equity model accounted for 86% of salary variance: over 60% by professional rank; approximately 16% by other rational equity factors; 3% by college and departmental parity; 3% by college and department affiliation; and 1% by nonrational equity factors. This model is recommended for studying, year-to-year changes in salary policies and for checking the importance of each factor in salary increase deliberations.
