A major textbook devoted to the theories that drive the study of Public Policy. Offering an accessible overview of the key components of public policy analysis - such as power and agenda setting, institutions, networks, socio-economic factors and the role of ideas - the text shows how different theoretical models relate to one another and explores how theory can be applied across a range of country settings. With its impressively comprehensive coverage, the book can be used as the sole text for teaching undergraduate and postgraduate courses worldwide on Public Policy, Policy Analysis and Theories of Public Policy.
