The Oxford Handbooks of Political Science is a ten-volume set of reference books offering authoritative and engaging critical overviews of the state of political science. This volume, the Oxford Handbook of Public Policy, surveys all the major approaches to public policy using an innovative structure that responds to the very latest scholarship. Its chapters touch upon institutional and historical sources and analytical methods, how policy is made, how it is evaluated and how it is constrained. In these ways, the Handbook shows how the combined wisdom of political science as a whole can be brought to bear on political attempts to improve the human condition.
