Difference Between Price Ceilings and Price Floor Both price ceilings and floors are forms of price controls. While a price ceiling dictates the maximum price of a good or service, a price floor refers to the lowest price for which a good or service may be sold.
When a price ceiling is set, a shortage occurs. For the price that the ceiling is set at, there is more demand than there is at the equilibrium price. There is also less supply than there is at the equilibrium price, thus there is more quantity demanded than quantity supplied.
