Final answer:
A trade barrier where the US limits coffee imports from Colombia is called a quota, which sets a maximum amount on how much can be imported, potentially leading to higher prices and reduced quantity in the US market.
Step-by-step explanation:
If the US limits the amount of coffee they will import from Colombia, the type of trade barrier being set is known as a quota. This is one of several trade barriers such as embargos and tariffs.
A quota specifically refers to a maximum quantity of a good that is allowed to be imported within a certain time period. By imposing a quota, the US government can limit the supply of imported coffee, which could raise prices and reduce the quantity of coffee available in the US market.
This might benefit domestic producers by reducing foreign competition, but could simultaneously lead to higher prices for consumers. In contrast to an embargo, which would prohibit all trade of coffee with Colombia, a quota simply restricts the amount to a set level.
