The public sector today permeates much of society. This wide-ranging reach is distilled into a cogent overview of governing in the twenty-first century in the latest edition of Johnson’s acclaimed work. In a clear and engaging style, the author examines the public-private collaborations through which public policies are shaped, implemented, and revised. Throughout, he emphasizes the role of public administrators in forming and maintaining the partnerships that advance the goals of government. Johnson’s well-organized survey draws on both classic works and current issues in describing the organization and operation of American government. Abundant sidebars on current challenges like immigration, health care, disaster preparedness, homeland security, infrastructure investment, and data privacy offer valuable examples of public administration in practice and illuminate the collaborative nature of American governance.
