This book tackles the challenging topic of corruption. It explores the evolution of a global prohibition regime against corrupt activity (the global anti-corruption regime). It analyses the structure of the transnational legal framework against corruption, evaluating the impact of global anti-corruption efforts at a national level. The book focuses on the United Nations Convention against Corruption (UNCAC) as the primary tool of the global anti-corruption regime. It provides new and engaging material gathered in the field, including first-hand accounts from actors at international, regional, and domestic levels. By documenting the experiences of diverse actors, the book makes a substantial contribution to literature on corruption and anti-corruption efforts. Synthesising empirical research with an exploration of theoretical literature on corruption and regime evolution results in novel suggestions for improvement of the global anti-corruption regime and its legal tools. The Global Anti-Corruption Regime is a well-rounded text with a wealth of new information that will be valuable to both academic and policy audiences. It clarifies the factors that prevent current anti-corruption efforts from successfully eliminating corrupt activity and applies the five-stage model of global prohibition regime evolution to the global anti-corruption regime. It will be of interest to researchers, academics, policymakers, and students interested in anti-corruption law, comparative law, transnational criminal law, international law, international relations, politics, economics, and trade.
