1. Criteria for Evaluating the Organizational Legitimacy: A Typology for Legitimacy Jungle

The legitimacy of organizations is a conceptual and scientific approach developed theoretically from different disciplines. For the measurement and analysis of legitimacy, researchers have developed typologies, coinciding in many aspects, but with significant differences in others. The diversity of typologies has its origin in the scientific theories not only on which framework the researchers who create them move but also in the object and method of analysis. This has led to the emergence of a profusion of terms used to evaluate the legitimacy of organizations. This gives rise to a jungle of terminology that makes it difficult for researchers to work, especially when empirical research is done. The present work establishes a typology of legitimacy, by taking into account the contributions of different authors, who contribute to define different aspects of the legitimacy of organizations. At the same time, we divide some concepts to achieve a greater clarity and definition of them, a relevant issue when trying to measure and evaluate. In this way, we create a somewhat broader typology than we usually find, defining eight types of legitimacy rather than the three or four types that we generally find in the literature.
