Difference between a quota and a tariff-rate quota?

• A. A quota directly restricts quantity with no tariff on the first units in the quota.
• B. A tariff-rate quota combines a low tariff with a higher tariff on excess.
• C. A tariff-rate quota is simply a fixed tariff with no quantity limit.
• D. A quota and a tariff-rate quota operate identically.

Answer: (B)

The key idea is how a tariff-rate quota uses both quantity limits and tariff rates. A tariff-rate quota sets a specific number of units that can enter at a low tariff, and anything beyond that quantity faces a higher tariff. This means imports are encouraged to stay within the quota because the price is lower there, but additional imports still come in at a higher price. A plain quota, by contrast, simply caps how much can enter without automatically applying a different tariff to the inside quantity. A fixed tariff with no quantity limit isn’t a quota at all. So the distinctive feature of a tariff-rate quota is the two-tier tariff structure that applies differently inside versus outside the quota.
