As a result, Americans will buy from a more expensive source, and the U.S. government will not receive customs revenue. Consumers save ten dollars per bike, but the government loses twenty dollars. Economists have shown that if a country joins such a “trade-orienting” customs union, the cost of that reorientation can outweigh the benefits of increased trade with other members of the customs union. The end result is that the customs union could make the country worse. Critics of bilateral and regional approaches to trade liberalization have many additional arguments. They indicate that these approaches could undermine and replace the WTO`s multilateral approach, which should be favoured for a comprehensive approach based on a non-discriminatory approach, instead of supporting and complementing it. . . .
