Tariffs are often created to protect infant industries and developing economies, but are also used by more advanced economies with developed industries. Here are five of the top reasons tariffs are used:
Protecting Domestic Employment
The levying of tariffs is often highly politicized. The possibility of increased competition from imported goods can threaten domestic industries. These domestic companies may fire workers or shift production abroad to cut costs, which means higher unemployment and a less happy electorate. The unemployment argument often shifts to domestic industries complaining about cheap foreign labor, and how poor working conditions and lack of regulation allow foreign companies to produce goods more cheaply. In economics, however, countries will continue to produce goods until they no longer have a comparative advantage (not to be confused with an absolute advantage).
Protecting Consumers
A government may levy a tariff on products that it feels could endanger its population. For example, South Korea may place a tariff on imported beef from the United States if it thinks that the goods could be tainted with disease.
Infant Industries
The use of tariffs to protect infant industries can be seen by the Import Substitution Industrialization (ISI) strategy employed by many developing nations. The government of a developing economy will levy tariffs on imported goods in industries in which it wants to foster growth. This increases the prices of imported goods and creates a domestic market for domestically produced goods, while protecting those industries from being forced out by more competitive pricing. It decreases unemployment and allows developing countries to shift from agricultural products to finished goods.
Criticisms of this sort of protectionist strategy revolve around the cost of
