Import Quota
Plain definition
A quota is a quantitative limit on how much of a good may be produced, imported, or sold — for example, a cap on the number of cars imported per year. Unlike a price control, it restricts quantity directly, letting the price adjust to clear the smaller market.
In economics
An import quota raises the domestic price, expands domestic production, shrinks consumption, and creates quota rents — the gap between the world price and the domestic price on each imported unit — which accrue to whoever holds the import licences. Economists generally prefer tariffs to quotas because tariff revenue goes to the treasury while quota rents go to licence holders.
Example
A country caps sugar imports at 1 million tonnes a year. Domestic sugar prices rise above the world price, local growers expand, consumers pay more — and importers holding licences pocket the price gap on every tonne as quota rent.
Quotas are often confused with tariffs, but the mechanics differ: a tariff is a tax per unit (a price instrument, with revenue to the government), while a quota is a hard quantity cap (a quantity instrument, with rents to licence holders). Quotas are also more rigid — when demand grows, a tariff lets imports expand while a quota chokes supply and sends prices soaring.
