Public policy is the result of interactions and dynamics among actors, interests, institutions, and processes. The formation of policy agendas, the enactment of public policies by Congress and the President, and the implementation and interpretation of policies by the bureaucracy and the courts are all stages in the policy process with which students should be familiar. Students should also investigate policy networks, iron triangles, and other forms of policy sub-governments in the domestic and foreign policy areas. The study of these will give students a clear understanding of the impact of federalism, interest groups, parties, and elections on policy processes and policy making in the federal context.
