Chapter 2 The Law of Comparative AdvantageQuestions we seek to answer in this chapter:(1) What is the basis for trade and what are the gains from trade?(2) What is the pattern of trade?Assumptions in international trade theory(1)two-nation, two-commodity world;(2)no trade restrictions to begin with;(3)perfect mobility of factors within the nations but no international mobility;(4)perfect competition in all commodity and factor markets;(5)no transportation costs.2.1 The Mercantilists’ Views on TradeA nation should export more than import to be rich and powerful, so the government have to do all in its power to stimulate the nation’s exports and discourage and restrict imports (especially the import of luxury consumption goods).托马斯·曼:《贸易带给英格兰的财富》2.2 Trade Based on Absolute AdvantageAbsolute advantageWhen one nation is more efficient than another in the production of one commodity but is less efficient than the other nation in producing a second commodity, then both nations can gain by each specializing in the production of the commodity of its absolute advantage and exchanging part of its output with the other nation for the commodity of its absolute disadvantage.The Law of Absolute advantage所有国家都可以通过自由贸易获利,倡导自由放任(laissez-faire,即政府尽可能少的干涉经济活动)。
