摘要:From 1996 to 2000, U.S. food
and agricultural exports averaged
about $60.6 billion per
year. The existence of import tariffs
in foreign markets was one of several
factors affecting the size of this
trade. Tariffs, which are taxes levied
by a government on imported
goods, drive a wedge between a
country¡¯s domestic prices and those
prevailing in international trade. By
altering the relative prices of imported
and domestically produced
goods, tariffs decrease the volume of
imports, as domestic production
tends to increase and consumption
decreases as a result of higher
domestic prices.
