Final answer:
The rest of the tariff amount is paid by exporting country producers, who absorb some of the tariff's cost by receiving reduced revenue from their sales.
Step-by-step explanation:
When a tariff is imposed on imports, the price of those imports increases, but not by the full amount of the tariff. The question posed is, when the price rises by less than the amount of the tariff, who pays the rest of the tariff amount? The answer is b) Exporting country producers.
They pay the remainder of the tariff through reduced revenue because they typically have to lower their prices to maintain competitiveness in the market after the tariff is applied. This economic phenomenon is part of international trade theory and can be represented graphically by showing the shift in supply and demand before and after a tariff is introduced, impacting equilibrium prices and quantities.
