Understanding Public Policy provides an introduction to the study of public policy, as well as an overview of the models that political scientists use to describe and explain political life. Offering students the tools needed to analyze public policy, author Thomas Dye highlights why governments pursue particular policies, and helps students understand the consequences of these policy choices. The fifteenth edition has been updated to reflect the key issues that have defined President Obama’s second term, with plenty of examples drawn from the headlines to help students see how public policy affects their own lives.
