A
price ceiling is a government-imposed
price control or limit on how high a price is charged for a product. Governments intend price ceilings to protect consumers from conditions that could make necessary commodities unattainable. However, a price ceiling can cause problems if imposed for a long period without controlled rationing. Price ceilings can produce negative results when the correct solution would have been to increase supply. Misuse occurs when a government misdiagnoses a price as too high when the real problem is that the
supply is too low. In an unregulated
market economy price ceilings do not exist.
