Governments intervene in international trade for political and economic reasons. Choices are abundant when selecting from the "arsenal" of trade weapons, including tariffs, subsidies, import quotas, voluntary export restraints (VERs), local content requirements (LCRs), administrative policies, and antidumping duties. Nations usually adopt trade regulations to achieve stated national objectives, but these regulations may have undesirable effects on many sectors of the economy, including higher prices for consumers, overproduction of agricultural products, and the insulation of nonefficient producers.
