The requirement that public officials declare their income and assets can help deter the use of public office for private gain. Income and asset disclosure (IAD) systems can provide a means to detect and manage potential conflicts of interest, and can assist in the prevention, detection, and prosecution of illicit enrichment by public officials. Growing attention to anticorruption policies, institutions, and practices has led to increased interest in financial disclosure systems and the role they can play in supporting national anticorruption strategies and in helping to instill an expectation of ethical conduct for individuals in public office. IAD systems are also a key element in the implementation and enforcement of provisions of the United Nations Convention against Corruption and other international anticorruption agreements. This attention has sparked interest among policy makers and practitioners in the design features and implementation practices that make for effective financial disclosure administration. The case studies collected in this volume are intended to profile a range of systems and practices to help respond to this growing interest.
