If the government, and through the enforcement of antitrust laws, believes the presence of competition in the marketplace achieves the highest level of market efficiency and fosters economic growth, why do governments have monopoly in providing some services such as DMV offices, professional licensing, business licenses, policing, public transportation, etc.? Is there efficiency in the government monopoly model? Or is there a room for improving efficiency in government agencies? Do you think we will have better public services if the government has competition?
