Q7 A of 25 Page 1

Note: The following question is for the Visually Impaired Candidates only, in lieu of Q. No. 7 (Alternative) :

The market for a commodity is in equilibrium. The supply of the commodity decreases, without any corresponding change in the demand


for the commodity.


Discuss the impact of the given change in the equilibrium price and the equilibrium quantity of the commodity.


● The x-axis represents quantity and the y-axis represents price.


● The market is in equilibrium at point E.


● A decrease in the supply will shift the supply curve towards the left.


● The original supply curve is SS.


● It will shift left towards S'S'.


● This will create excess demand which will lead to an increase in competition among the buyers.


● The new supply curve intersects the original demand curve at a higher equilibrium point of E'.


● The equilibrium price will increase from OPe to OPe'.


● The equilibrium quantity will fall from OQe to OQe'.
