When the government imposes upper limit on the price of a good it is called maximum price ceiling. It is fixed below the equilibrium price.
Implication (maximum price ceiling): It will lead to excess demand. This in turn may lead to black marketing of goods. When the government imposes lower limit on the price of a good, it is called minimum price ceiling.
Implication (minimum price ceiling): It leads to excess supply.This in turn may lead to illegal selling below the ceiling price as the producers are not able to sell what they desire to sell.
