System in which goods, capital, and labour flow freely between nations, without barriers that could hinder the trade process. Many nations have free trade agreements, like NAFTA (North America Free Trade Agreement, between Canada, United States and Mexico) and several international organizations promote free trade between their members. A number of barriers to trade are struck down in a free trade agreement. Taxes, tariffs, and import quotas are all eliminated, as are subsidies, tax breaks, and other forms of support to domestic producers. Restrictions on the flow of currency are also lifted, as are regulations that could be considered a barrier to free trade. In conclusion, free trade enables foreign companies to trade just as efficiently, easily, and effectively as domestic producers. See economic integration.
