請依下文回答第 15 題至第 19 題 Free trade is a free market policy followed by some international markets in which governments do notrestrict imports from, or exports to, other countries. Trade treaties increase freedom to trade and do not resultin loss of sovereignty. However, most governments still impose some protectionist policies that are intendedto support local employment, such as applying tariffs to imports or subsidies to exports. Governments mayalso restrict exports of natural resources. Other trade barriers include import quotas, taxes, and non-tariffbarriers, such as regulatory legislation.Take the United States as an example. There is a growing rhetoric about imposing tariffs and limitingfreedom to trade internationally. It reflects a resurgence of old arguments that stay alive in large part becausethe benefits of free international trade are often diffuse and hard to see, while the benefits of shieldingspecific groups from foreign competition are often immediate and visible. This illusion fuels the commonperception that free trade is detrimental to the U.S. economy. It also tips the scales in favor of specialinterests seeking protection from foreign competition, which results in thousands of tariffs, quotas, and otherbarriers imposed to trade.However, restrictions on foreign trade all too often harm the very people they aim to protect, i.e.,American consumers and producers. Trade restrictions limit the choices of what Americans can buy; theyalso drive up the prices of everything from clothing and groceries to the materials manufacturers use to makeeveryday products. Lower-income Americans generally bear a disproportionate share of these costs.Not onlydo they spend more of their income on consumption goods, many of the goods they consume are subject tohigher tariffs than more expensive goods of the same type.There is a broad consensus among economists that protectionism has a negative effect on economicgrowth and economic welfare, while free trade and the reduction of trade barriers to trade has a positiveeffect on economic growth. However, they also point out that liberalization of trade can cause significant andunequally distributed losses and the economic dislocation of workers in import-competing sectors.
