Suppose that the short-run supply and demand for pineapples in a certain town are described by the following two equations:
QS= 1,000,
QD= 2,000−200p.
Pineapples are an imported produce in this market, so the government imposes a tax of $1 per pineapple. Which of the following statements is true?
The correct option would be
The pre-tax equilibrium in the market would be where
or
or
or
, and
or
or
. But, if a tax is imposed on the producers, since the supply is
inelastic (invariant to price), the tax would entirely be paid by
producers. Hence, the price received to suppliers would be
equilibrium price minus tax, ie $5 minus $1 or $4, while price paid
by buyers would be the equilibrium price $5, and the equilibrium
quantity would be same as before of 1000 units. The dead-weight
loss occurs in case where the quantity traded in the market is
reduced, which in this case is 0, and hence the dead-weight loss is
zero.
The algebra is as follows. The quantity supplied is taken as
, and in this case, as
since the slope of supply curve is zero. The imposition of tax
affects the supply curve as
for t be the tax and p-t is price received by suppliers, and in
this case it would be
or
. As can be seen, the supply curve is unaltered, and the market
equilibrium quantity and price (price paid by buyers) is same as
before. All that changes is the price received by sellers.
