A $3 tax is imposed on the sale of a particular industrial product. If the demand for that product is QD=60-5P and supply for that product is QS=10P-30. Calculate the equilibrium price(s) and quantity after the tax.
In this case, Producer will get $(P-3) for every $P paid by consumer.
New demand function will remain unchanged. i.e.
QD=60-5P
New Supply function can e obtained by replacing P by (P-3)
QS=10*(P-3)-30=10P-30-30=10P-60
In Equilibrium, QD=QS
60-5P=10P-60
120=15P
P=$8 per unit
Now calculate QD and QS at P=$8
QD=60-5P=60-5*8=20
QS=10P-60=10*8-60=20
Equilibrium Price after tax= $8 per unit
(Consumer will pay a price of $8 per unit. Producer will have $5 per unit after paying a tax of $3 per unit)
Equilibrium quantity after tax= 20 units
