Editor's Notes

  1. There are 100 acres of land. Australia can dedicate all of its land to produce cotton, in which case it produces 600 bales (or 6 bushels per acre). On the other hand, if Australia dedicates all of its land to produce wheat, it produces 200 bushels (or 2 bushels per acre).
  2. Edward Leamer of UCLA has concluded that a short list of factors accounts for a large portion of world trade patterns. Natural resources, knowledge capital, physical capital, land, and skilled and unskilled labor.
  3. Because evidence suggests that economies of scale are exhausted at relatively small size in most industries, it seems unlikely that they constitute a valid explanation of world trade patterns.
  4. The average tariff on imports into the United States is about 5 percent. A U.S. firm attempting to monopolize a domestic market violates the Sherman Antitrust Act of 1890, prohibiting predatory pricing. The Comprehensive Trade Act of 1988 contains clauses that permit the president to impose trade sanctions when investigations reveal dumping by foreign companies or countries.
  5. The most recent round of world trade talks sponsored by GATT, the “Uruguay Round,” began in Uruguay in 1986. The “final Act” of the Uruguay Round of negotiations is the most comprehensive and complex multilateral trade agreement in history.
  6. NAFTA was ratified by the U.S. Congress in late 1993 and went into effect on the first day of 1994.
  7. We can ban imports and give up the gains from free trade, acknowledging that we are willing to pay premium prices to save domestic jobs in industries that can produce more efficiently abroad. Or we can retrain workers for jobs with a future, or adopt programs to relocate people in expanding regions. An infant industry is a young industry that may need temporary protection from competition from the established industries of other countries in order to develop an acquired comparative advantage.
