A Ceramic Plates QuotaWith an import quota of 2 million ceramic plates, consumers face the pink supply curve made up of the U.S. supply plus the 2 million plates that can be imported. Imports are not available for less than $9, so the pink U.S.-plus-quota supply curve does not extend below $9. At the $12 equilibrium price with the quota, a quantity of 6 million plates are purchased, 4 million of which are supplied domestically.
