This is the International Undergraduate Program of Public Policy and Management’s core course in public policy. The course is developed to enhance the knowledge of students after studying The Introduction of Public Policy in the previous semester. Its focus is on why and how public policies are developed. The goal of this course is to deepen our understanding of how public policy is formulated. This course is designed with a particular emphasis played by political actors, institutions and context. From interest groups to mayors and the role of the media in foreign affairs we will continually ask: how and why do some issues gain traction with the decision makers and others ignored? We will examine how public policy is crafted, negotiated and enacted. How would one define the success of a policy? This course addresses these questions by examining several analytic frameworks used by political scientists to help describe and explain government policies. These models are not mutually exclusive but, solely, or in combination, help to highlight different aspects of the policymaking process. Some of them focus more on the actors of public policy (e.g. game theory, group theory, or advocacy coalition), while others emphasize the process of making public policy (e.g. stages model). Students will gain a critical appreciation of how a triangulation of various political science approaches can help us to think clearly about societal problems and alternative responses to them.
