In the first book of its kind, Leo Huberts provides a much-needed critical synthesis of cutting-edge research on public sector integrity. The study explores a range of issues relating to the topic, including the definition and importance of public sector integrity and the various methodological approaches to the field, as well as considering the causes for the violation of values associated with integrity. It examines the steps that can be taken to improve adherence to these values in an attempt to put ethics on the agenda of government and governance research. The result is a study that will constitute a vital resource for students and scholars of comparative politics, public policy and public administration.
