中等ECON-ELAS-019
A per-unit tax is placed on sellers. Demand is perfectly inelastic and supply is upward sloping. Who bears the tax?
A. Sellers bear the full tax.
B. The tax is shared equally.
C. Buyers bear the full tax.✓ 答案
D. Neither side bears it because the price cannot change.
解說
When demand is vertical, buyers do not reduce quantity as price rises, so the price paid by buyers rises by the full tax. The more inelastic side bears more of a tax. Equal sharing is not a rule; it depends on the two elasticities.
