A comparative lega, economic and political analysis of the impact of constitutional law and of international economic law on the foreign trade laws and policies of the major trading countries. The countries covered include the United States, Japan, EC and EFTA countries, plus regional trade organizations such as the EEC and EFTA. Developments such as the Cadana-US Free Trade Agreement are also covered. As the benefits of constitutionalism and liberal trade do not depend on the nationalities of traders, producers and consumers, the contributions criticize the frequent "double standards" of "fair trade laws" and suggest "constitutionalism reforms" of international and domestic foreign trade laws and policies.
