Book excerpt: Public accountability is a hallmark of modern democratic governance and the foundation of the popular performance management movement. Democracy is just an empty exercise if those in power cannot be held accountable in public for their acts and omissions, for their decisions, their policies, and their expenditures. This book offers a finely detailed and richly informed consideration of accountability in both government and the contemporary world of governance. Twenty-five leading experts cover varying aspects of the accountability movement, including multiple and competing accountabilities, measuring accountability, accountability and democratic legitimacy, and accountability and information technology, and apply them to governments, quasi-governments, non-government organizations, governance organizations, and voluntary organizations. Together they provide the most comprehensive consideration of accountability currently available, with a blend of theoretical, empirical, and applied approaches.
