Toward a New Measure of Organizational Legitimacy: Method, Validation, and Illustration

Measures of organizational legitimacy fall in three categories, based, respectively, on the observation of code adoption, firm linkages, and media coverage. Such variety reflects the absence of consensus definitions. Because legitimacy involves perceptions of social congruence, the author argues in favor of a perceptual measure based on media content analysis. The author extends existing media-based indicators by offering a multidimensional measure of legitimacy, the raw legitimacy vector (RLV), which accounts for the heterogeneity of perceptions across space and time. The article details a three-step methodology to compute RLV and illustrates its applicability using data on the global defense industry. The author finds strong support for RLV’s factorial, convergent, discriminant, and criterion-related validity and demonstrates that RLV performs better than alternative measures. The paper contributes to research by identifying four stable dimensions of legitimacy (environment, competition, accountability, and transactions), by distinguishing empirically legitimacy and reputation, and by offering a measure suited for international comparison in both legitimate and contested industries.
