Abstract: This dissertation examines how categories — groupings that are built upon social and cognitive similarities — affect the evaluation of organizations in markets. Research shows that market audiences are likely to penalize organizations that combine multiple categories. Questioning the past studies' underlying assumptions, my work contextualizes this demand of categorical purity by studying the role of (i) category nesting, that is the hierarchical disposition of categories, (ii) audience members’ heterogeneity in expertise and modes of categorization (the way individuals group entities together), and (iii) the differences of valence among categories themselves. Using experimental tests (Chapter 1), longitudinal data on venture capital deals worldwide from 1994 to 2017 (Chapter 2) as well as theoretical developments (Chapter 3), this dissertation provides evidence of conditions under which categorically atypical organizations are better appraised than categorically pure organizations in markets. This work offers contribution to organization theory and economic sociology by speaking to research on market categories, experts’ evaluations and optimal distinctiveness.
