How do governments use trade barriers to control international trade?

"supercomputers and lasers, to be exported to countries that are not allies. Although this embargo costs U.S. firms billions of dollars each year in lost sales, it keeps enemies from using the latest technology in their military hardware. Government rules that give special privileges to domestic manufacturers and retailers are called buy-national regulations . One such regulation in the United States bans the use of foreign steel in constructing U.S. highways. Many state governments have buy-national rules for supplies and services. In a more subtle move, a country may make it hard for foreign products to enter its markets by establishing customs regulations that are different from generally accepted international standards, such as requiring bottles to be quart size rather than liter size. Exchange controls are laws that require a company earning foreign exchange (foreign currency) from its exports to sell the foreign exchange to a control agency, usually a central bank. For example, assume that Rolex, a Swiss company, sells 300 watches to Zales Jewelers, a U.S. chain, for US$600,000. If Switzerland had exchange controls, Rolex would have to sell its U.S. dollars to the Swiss central bank and would receive Swiss francs. If Rolex wants to buy goods (supplies to make watches) from abroad, it must go to the central bank and buy foreign exchange (currency). By controlling the amount of foreign exchange sold to companies, the government controls the amount of products that can be imported. Limiting imports and encouraging exports helps a government to create a favorable balance of trade. 3.4 Fostering Global Trade 4. How do governments and institutions foster world trade? Antidumping Laws U.S. firms don’t always get to compete on an equal basis with foreign firms in international trade. To level the playing field, Congress has passed antidumping laws. Dumping is the practice of charging a lower price for a product (perhaps below cost) in foreign markets than in the firm’s home market. The company might be trying to win foreign customers, or it might be seeking to get rid of surplus goods. When the variation in price can’t be explained by differences in the cost of serving the two markets, dumping is suspected. Most industrialized countries have antidumping regulations. They are especially concerned about predatory dumping, the attempt to gain control of a foreign market by destroying competitors with impossibly low prices. The United States recently imposed tariffs on softwood lumber from Canada. Canada was found guilty of pricing softwood lumber at between 7.72 and 4.49 percent below their costs. U.S. customs officers will now levy tariffs on Canadian timber exports with tax rates from 17.41 percent to 30.88 percent, depending on the business. 20 C O N C E P T C H E C K 1.
