Under what condition increase in demand would not make any effect on equilibrium price ?

Answer»

SOLUTION :Case I:when supply also increase at the same rate as the demand increases
In the given diagram PRICE is measured on vertical axis and quantity demanded and supplied is measured on HORIZONTAL axis. INITIALLY, the equilibrium price is OP and equilibrium quantity is OQ. But when "demand and supply both increase at the same rate " then.
(i) Equilibrium price remains constant at OP, and
(ii) Equilibrium quantity rises from OQ to `OQ_(1)`
Case II: When supply becomes perfectly elastic
In the given diagram price is measured on vertical axis and quantity demanded and supplied is measured on horizontal axis. Initially, the equilibrium price is OP and equilibrium quantity is OQ. But when "supply becomes perfectly elastic and demand increases then,
(i) Equilibrium price remains constant at OP, and
(ii) Equilibrium quantity rises froma OQ to `OQ_(1)`
