“…The range of these findings likely resulted from the samples employed as each study used data from non-random samplings of institutions drawn from niche subsets of the very large American college market, making comparisons between the studies diffi-cult due to the heterogeneity of the institutions examined. Monks and McGoldrick (2004) and Essaji and Horton (2010), examined administrators below the rank of president and found that females earned between four and thirteen percent less than their male counterparts; however, neither study examined any personal characteristics of the administrators such as academic field and academic rank which have been shown to affect the compensation of university presidents / vice-chancellors (e.g. Baimbridge & Simpson, 1996;Monks, 2007), which undoubtedly biases their estimates of the gender earnings gap given differences in the distribution of males and females across academic fields (Binder, Krause, Chermak, Thacher, & Gilroy, 2010;Brown, Troutt, & Prentice, 2011;Warman, Woolley, & Worswick, 2010) and academic ranks (Ginther & Hayes, 2003;Mcdowell & Smith, 1992;Ornstein, Steward, & Drakich, 2007;Wijesingha & Ramos, 2017).…”
