Why are tariffs and trade barriers used?
Tariffs are often created to protect the domestic industries and developing economies, but are also used by more advanced economies with developed industries.
The benefits of tariffs are uneven. Because a tariff is a tax, the government will see increased revenue as imports enter the domestic market. Domestic industries also benefit from a reduction in competition, since import prices are artificially inflated. Unfortunately for consumers - both individual consumers and businesses - higher import prices mean higher prices for goods.
