Corruption is an almost universal and persistent feature of the modern state. Commentators primarily view corruption as a major obstacle to development, whereas dissenting voices claim that corruption has the power to facilitate trade that would otherwise not have taken place. This comprehensive collection presents the most significant works contributing to our understanding of this debate, focusing on the key conceptual and theoretical issues and discussing anti-corruption policies. Alongside an original introduction by the editors, this collection is a highly valuable asset to scholars and academics alike.
