Concept:A quota is a government limit on the quantity of a good that can be imported.
Governments impose quotas to protect local industries and improve the economy, not to reduce their own revenue.
Explanation:Quotas restrict imports.
They are used to support strategic and infant industries, prevent dumping, create employment, and improve the balance of payments.
