In economics, a government monopoly (or public monopoly) is a form of coercive monopoly in which a government agency or government corporation is the sole provider of a particular good or service and competition is prohibited by law. It is a monopoly created by the government. It is usually distinguished from a government-granted monopoly, where the government grants a monopoly to a private individual or company.
A government monopoly may be run by any level of government - national, regional, local; for levels below the national, it is a local monopoly. The term state monopoly usually means a government monopoly run by the national government, although it may also refer to monopolies run by regional entities called "states" (notably the U.S. states).
