“…Chatterjee and Hambrick (2007, 2011) pioneered the use of the CEO narcissism index as a composite measure of several narcissism indicators observed in firm reports and publicly available documents. The CEO narcissism index has since become the most frequently used method (23 of 42 articles; Bianchi, 2014; Buchholz, Jaeschke, Lopatta, & Maas, 2018; Buyl et al, 2017; Chatterjee, 2009; Chatterjee & Hambrick, 2007, 2011; Engelen, Neumann, & Schmidt, 2016; Gerstner, König, Enders, & Hambrick, 2013; Ingersoll, Glass, Cook, & Olsen, 2017; Judd, Olsen, & Stekelberg, 2017; Kashmiri, Nicol, & Arora, 2017; Liu, 2009; Marquez-Illescas, Zebedee, & Zhou, 2018; Oesterle, Elosge, & Elosge, 2016; Olsen et al, 2014; Olsen & Stekelberg, 2016; Patel & Cooper, 2014; Rijsenbilt, 2011; Rijsenbilt & Commandeur, 2013; Schrand & Zechman, 2012; Tang, Mack, & Chen, 2018; Zhu & Chen, 2014, 2015).
