Tariffs， Quotas

Tariffs and quotas are two types of trade barriers that are used by governments to restrict imports and protect domestic industries.

Tariffs are taxes that are imposed on imported goods. They increase the price of the imported goods, making them less competitive with domestic products. Tariffs can be specific (a fixed amount per unit of imported goods) or ad valorem (a percentage of the value of the imported goods).

Quotas, on the other hand, are limits on the quantity of a particular product that can be imported during a specified period of time. Quotas can be absolute (a fixed quantity) or tariff-rate (a specified quantity with a lower tariff rate, and a higher tariff rate for quantities above the quota).

Both tariffs and quotas can have an impact on the price of goods, consumer choices, and the competitiveness of domestic industries. While they may provide short-term benefits to domestic industries, they can also lead to higher prices for consumers and reduced competition in the long run.
