This article explores the relationship between corporate social responsibility and authenticity by developing a framework that explains the characteristics of CSR activities that lead to a perception by stakeholders that a firm’s CSR efforts are genuine. Drawing on the authenticity literature, we identify two core dimensions of authenticity that impact stakeholder perceptions of CSR: distinctiveness and social connectedness. Distinctiveness captures the extent to which a firm’s CSR activities are aligned with their core mission, vision and values while social connectedness refers (...) to the degree to which an organization’s CSR efforts are embedded in a larger social context. We use this framework to explore the question ‘when are a firm’s CSR efforts most likely to be perceived as authentic by stakeholders?’ and find that both of these dimensions are necessary; social connectedness or distinctiveness alone are necessary but insufficient conditions for perceptions of authenticity to occur. A detailed exploration of authenticity, therefore, advances research in the CSR domain that may help mend the growing divide between business and society. (shrink)
