Part of the Advances in Spatial Science book series (ADVSPATIAL)


Ad valorem tariffs are a trade policy instrument used by nearly all nations to restrict imports of a wide variety of commodities. Recent emphasis on tariffication as a means of trade liberalization underscores the importance of appropriately incorporating discriminatory ad valorem tariffs (tariffs imposed by the importing country that vary according to the exporting country) into spatial economic models. Both the recently-approved North American Free Trade Agreement (NAFTA) and the General Agreement on Tariffs and Trade (GATT) negotiations specify tariffication as a mechanism to lower trade barriers.
