假设挪威与瑞典相互贸易，揶威出口鱼，而瑞典出口沃尔沃汽车。假定两国的消费偏好相同，但是生产可

能性边界不同：挪威由于有较长的沿大西洋的海岸线，因此捕鱼效率高;瑞典的资本相对充裕，故而汽车的生产效率高。据此，根据标准贸易模型论述这两国的贸易利益。

Assume that Norway and Sweden trade with each other， with Norway exporting fish to Sweden， and Sweden exporting Volvos (automobiles) to Norway. Illustrate the gains from trade between the two countries using the standard trade model， assuming first that tastes for the goods are the same in both countries， but the production possibilities frontiers differ: Norway has a long coast that borders on the north Atlantic， making it relatively more productive in fishing. Sweden has a greater endowment of capital， making it relatively more productive in automobiles.
