Public policy is a term for rules and regulations laid down by the government to serve as a solution to a specific problem. Public policy can cover anything from welfare to highway cleanliness to public health. Most of the time, public policy is decided on by the United States Congress, who passes a solution into law. The study of public policy is important to business, since many decisions that they make can affect those involved in business. For example, tax laws change every year, and what the government allows large and small businesses to do is constantly updated. Having knowledge of the public policy and how to research it when it changes is very important in the world of business. Public policy affects everyone from children to senior citizens, from the poor to the rich. A background course in public policy can be very helpful as a business major, since the government plays an important role in many business operations in the United States.
