Study Notes
Trade protection involves government intervention in international trade through trade restrictions to protect the domestic economy from international competition. It can also preserve foreign currency reserves and serve as a political tool.
- Tariffs — indirect taxes levied on imports to protect domestic industries and raise government revenue. Example: A tariff increases the price of imports, reducing the quantity imported and increasing domestic production.
- Quotas — legal limits on the quantity of a good that can be imported over a period. Example: A quota limits imports, raising domestic prices and benefiting domestic producers.
- Consumer Surplus — the difference between what consumers are willing to pay and what they actually pay. Example: Consumer surplus decreases when tariffs or quotas increase prices.
- Producer Surplus — the difference between what producers are willing to accept and what they actually receive. Example: Producer surplus increases with tariffs or quotas as domestic prices rise.
