This article engages with the burgeoning literature on the conceptualization of corruption, a literature animated by the view that failures in anticorruption practice—the limited progress made in tackling global corruption—are in part a consequence of the ways in which corruption is theorized by academics. In response, the article proposes and elaborates a four-dimensional definition of corruption with detailed subdefinitions and seeks to advance thinking in both academic and practitioner circles on how corruption can be most effectively identified in context. The article makes five distinct contributions to live debates in the conceptual literature and clarifies several ambiguities and disagreements that have arisen within it.
First, it presents a set of grounded subdefinitions that make explicit the scope of each dimension of the definition. Second, it recommends applying the four dimensions in a predetermined sequence, enabling uncertainties or gray areas in each dimension to be resolved and clarified by subsequent dimensions. Third, it addresses the much-contested “abuse” dimension, acknowledging not only the flexibility required to identify abuses in different political and social settings but also the need to limit the scope of abuse so that it is not wholly idiosyncratic or relative. Fourth, it incorporates systemic and institutional forms of corruption, which creates an important bridge between individual and institutional approaches to corruption. Finally, it offers a defense for integrating the notion of public interest into the definition, which not only provides additional clarity to the conceptualization but also does justice to the reasons we care about corruption in the first place.
