[Policy science and health policy].
Policy science provides the analytical frameworks to examine (1) the process of policy formation and implementation (Issue definition, Agenda setting, Alternative development, Decision and implementation, and Appraisal); (2) the initial and final shapes of policy content (Temporal and special distribution of costs and benefits, Selection of administrative organizations, and Choice of instruments to secure policy compliance); and (3) the effects and efficiencies of policy (Expected and unexpected effects of policy, beneficial and adverse ones). These three aspects are closely associated, and determine the functions of policy in society. Overseas, the application of policy science framework to health issues has thus far produced substantive knowledge which helps to improve both the policy making and policy designs, and at the same time, has provided good opportunities on which the workings of health and policy, both at the social and individual levels, are explored. The paper first outlines the themes and frameworks of political science, and then, introduces their application to the field of health. Issues associated with human life and health have special characteristics that distinguish them from those of other market commodities: special values placed on life and health, information inequality between service providers and consumers, and externalities, leading to a variety of moral hazards and market failures. Furthermore, there are some conflicts in values and technical opinions in society, regarding both the ends and means of health policies. In addition to the main topics in the field, empirical studies, from Japan or from other countries, are also summarized. Finally, future research needs and expectations are addressed.
