Quota rent

Quota rent is the economic benefit or extra profit that arises when a government imposes a trade quota, limiting the quantity of a good that can be imported. Because the supply of that good is restricted, its market price typically rises above the world price. This difference between the domestic price (with the quota) and the world price is the quota rent. It is effectively the extra earnings captured by domestic producers or license holders due to the import restriction, representing a transfer of value from consumers or foreign producers to those with import licenses.
