Domestic policy, which is also known as public policy, is concerned with government programs and actions that focus on issues such as public transportation, health care, education, and environmental protection. Once the government passes a public proposal into law, the government officials must determine how to enforce the new law since there are four different methods or techniques that the government may employ to apply this new policy (such as: authoritative, incentive, capacity, hortatory). When a government imposes a fine to coerce citizens to follow a law, it is employing an authoritative method of enacting domestic policy, since it is considered a destructive and immoral behaviour.
