This volume features a distinguished, international group of scholars and practitioners who provide a comparative account of ethics regulations across four Western democracies: the United States, the United Kingdom, Canada, and Italy. They situate conflict-of-interest regulations within a broader discourse involving democratic theory; identify the structural, political, economic, and cultural factors that have contributed to the development of these regulations over time; and assess the extent to which these efforts have succeeded or failed across and within different branches and systems of government. Collectively, they provide an invaluable survey of the development, function, and impact of conflict-of-interest regimes in public life.
