As valuable assets of corporations, governments and not-for-profit organizations, brands have attracted considerable research attention. We know a lot about how brands create knowledge in their target consumers’ minds, which leads to an attitude towards or relationship with the brand that translates into a number of favorable outcomes. The resultant brand equity is often associated with improved performance of the organization in reaching its objectives such as increasing market value. We know less about the dynamic nature of brand equity and, in particular, how it may interact with turbulence in the external environment in which the brand competes, both positively and negatively. We examine three key dimensions of brand equity—brands’ access to their target markets, perceived differentiation, and level of brand engagement with their target consumers—that influence the effect environmental turbulence has on diminishing equity or providing future opportunities for brand equity growth. Borrowing from the strategy literature, we suggest ways in which agile and resilient firms can use brand equity to resist environmental turbulence, recover from any damage that may result from it, and reinvent themselves to leverage opportunities created by a radically altered external environment. We close with a set of propositions intended to guide managers in anticipating and responding to environmental turbulence and inform and shape future research in this area.
