Concept of Price Ceiling

It is not very uncommon to come across instances where the government fixes a maximum allowable price for certain goods. The government-imposed upper limit on the price of a good or service is called a price ceiling. A price ceiling is generally imposed on necessary items like wheat, rice, kerosene, sugar etc. The objective of the price ceiling is to restrict the price of a good so that it becomes affordable for consumers to buy. However, it does not always generate the desired results. Most of the time, intervention by the government in the form of a price ceiling leads to various socio-problems.

The market determined price of a good is Rs. 40.The government determines the price ceiling on the good as Rs. 25. Calculate the excess demand/excess supply it will cause if the demand and supply functions are Qd= 200 – p and Qs=120+ p respectively.

Solution

✅ Correct Option: 3

Option 1 -> At price ceiling Rs. 25: Qd = 200-25 = 175, Qs = 120+25 = 145. Excess demand = 175-145 = 30 units, not 25.

Option 2 -> Price ceiling below equilibrium creates shortage (excess demand), not excess supply.

Option 3 -> At price ceiling Rs. 25: Qd = 200-25 = 175, Qs = 120+25 = 145. Excess demand = 175-145 = 30 units.

Option 4 -> Price ceiling below equilibrium creates shortage (excess demand), not excess supply.


Hence, Excess demand for 30 units -> A price ceiling is a maximum price set below the equilibrium price. At Rs. 25 (below equilibrium Rs. 40), quantity demanded (175 units) exceeds quantity supplied (145 units), creating excess demand of 30 units. This shortage occurs because consumers want to buy more at the lower price, but suppliers are willing to supply less -> correct
