- Public policy can be defined as "anything a government chooses to do or not to do" according to Thomas Dye. This definition emphasizes that governments are the primary actors in public policy and their decisions, whether to act or not act, constitute public policy.
- Governments are uniquely able to make authoritative decisions on behalf of citizens, backed by legislation. Public policy also involves a series of interrelated decisions made across government to address problems.
- Studying public policy allows us to scientifically understand the causes and consequences of policies, help solve practical problems, and make policy recommendations. It also allows us to learn what governments are doing in key areas, the causes of their decisions, and the impacts of their policies
