Free trade improves the allocation of global resources. If countries or people can act against the items they need, they can focus on producing the ones they can do best. Imports tend to suppress inflation because each product or service comes from the best source of supply. According to the CATO Institute, “we benefit from the lower prices that give us imports, and we can use the money we save to buy things that are made at home.” Originally, the General Agreement on Tariffs and Trade (GATT 1994) defined the Free Trade Agreement to cover only trade in goods.  Article V of the General Agreement on Trade in Services (GATS) defines “economic integration agreement” as an agreement with a similar purpose, i.e. to promote the liberalization of services.  However, in practice, the term is now often used to refer to agreements that include not only goods, but also services and even investments. Environmental provisions have also become increasingly common in international investment agreements, such as free trade agreements. :104 It should be noted that the authorisation of origin criteria varies between intermediate consumption of origin within and outside a free trade agreement. Normally, inputs from one part of the FTA are considered to be products originating in the other party when they are included in the manufacturing process of that other party. Sometimes the production costs incurred by one party are also considered to be those of another party.
Preferential rules of origin generally provide for such a difference in treatment in the determination of cumulation or accumulation. Such a clause also explains the above-mentioned effects of a free trade agreement on the creation and reorientation of trade, given that a party to a free trade agreement has an incentive to use inputs originating in another party in order for its products to be eligible for originating status.  There are important differences between customs unions and free trade areas. Both types of trading blocs have internal agreements that the parties conclude to liberalize and facilitate trade between them. The key difference between customs unions and free trade areas is their treatment vis-à-vis third parties[clarification of concepts required]. While a customs union requires all parties to set and maintain identical external tariffs for trade with non-parties, parties to a free trade area are not subject to such a requirement. Instead, they may import and maintain the customs procedure applicable to imports from non-Parties which they deem necessary.  In a free trade area without harmonized external customs duties, the Parties will adopt a system of preferential rules of origin to eliminate the risk of relocation.
