Government’s Role in the Economy
While consumers and producers obviously make most decisions that mold the economy, government activities have at least four powerful effects on the U.S. economy.

• direct services. Each level of government provides direct services. The postal system, for example, is a federal system
serving the entire nation, as is the large military establishment. By contrast, the construction and maintenance of most highways is the responsibility of individual state governments. The public education systems are primarily paid for by state, county or city governments. In general, police and fire protection are the responsibilities of local government.

• regulation and control. The government regulates and controls private enterprise in many ways in order to ensure that business serves the best interests of the people as a whole. Regulation is usually considered necessary in areas where private enterprise has been granted a monopoly, such as in electric or local telephone service, or in other areas where there is limited competition, as with the railroads. Public policy permits such companies to make reasonable profits, but limits their ability to raise prices “unfairly” (as defined by the regulators) because the public depends on their services. Often control is exercised to protect the public, for example, when the Food and Drug Administration bans harmful drugs, or requires standards of quality in food. In other industries, government sets guidelines to ensure fair competition without using direct control.
