Chapter 5: Q.30 (page 131)
30. In a market where the supply curve is perfectly inelastic, how does an excise tax affect the price paid by consumers and the quantity bought and sold?
Short Answer
If supply is completely inelastic, an excise tax has no effect on purchasers, but the net price received by producers falls short of the price paid by buyers by the whole value of the excise tax. With the exercise tax, suppliers will be responsible for the entire tax burden.
