An import quota is a type of trade restriction that sets a physical limit on the quantity of a good that can be imported into a country in a given period of time. Quotas, like other trade restrictions, are typically used to benefit the producers of a good in that economy.
How do production quotas work?
A quota refers to a measure that limits, either minimum or maximum, on a particular activity. Quotas are usually enacted by governments or organizations to protect domestic industries. In short, it limits the number of goods a country can export or import during a certain period of time.
How do quotas affect prices?
An import quota will raise the domestic price and, in the case of a large country, lower the foreign price. The difference between the foreign and domestic prices after the quota is implemented is known as a quota rent. An import quota will reduce the quantity of imports to the quota amount.
