Free trade is a policy by which a government does not discriminate against imports or interfere with exports by applying tariffs (to imports) or subsidies (to exports). A free-trade policy does not necessarily imply, however, that a country abandons all control and taxation of imports and exports.
The theoretical case for free trade is based on Adam Smithâs argument that the division of labor among countries leads to specialization, greater efficiency, and higher aggregate production. (Seecomparative advantage.) From the point of view of a single country there may be practical advantages in trade restriction, particularly if the country is the main buyer or seller of a commodity. In practice, however, the protection of local industries may prove advantageous only to a small minority of the population, and it could be disadvantageous to the rest.
Tariffs are a type of tax on imported goods that typically result in higher retail prices for consumers.
