A Tariff on Ceramic PlatesA tariff of $3 per imported ceramic plate effectively raises the curve that represents the supply from the rest of the world by $3. To receive an imported plate, one must pay $9 to the foreign suppliers plus $3 for the tariff, for a total of $12. Domestic firms can then charge up to $12, for which they are willing to supply 4 million plates. Domestic consumers demand 6 million plates for $12 each. Two million plates will be imported to make up the difference between the domestic supply and the domestic demand. This is 2 million less than the 4 million plates imported without the tariff.
