This book investigates the history, development, and current state of anti-corruption agencies in Latin America. In recent decades, specialized anti-corruption agencies have sprung up as countries seek to respond to corruption and to counter administrative and political challenges. However, the characteristics, resources, power, and performance of these agencies reflect the political and economic environment in which they operate. This book draws on a range of case studies from across Latin America, considering both national anti-corruption bodies and agencies created and administered by, or in close coordination with, international organizations. Together, these stories demonstrate the importance of the political will of reformers, the private interests of key actors, the organizational space of other agencies, the position of advocacy groups, and the level of support from the public at large. This book will be a key resource for researchers across political science, corruption studies, development, and Latin American Studies. It will also be a valuable guide for policy makers and professionals in NGOs and international organizations working on anti-corruption advocacy and policy advice.
