Questions and Answers Lesson 1 International Trade (I) 1. How would you define international trade? It can be defined as the exchange of goods and services produced in one country with those produced in another. 2. Why did international trade first begin? The distribution of natural resources is uneven. Some countries are abundant in resources, while elsewhere reserves are scarce or even nonexistent. And a country may be rich in some resources but poor in others. The country that is rich will export some of its resources to the country that is in need. The opposite is also true. That is the reason why international trade first began. 3. What is the new incentive for trade that arose with the development of manufacturing and technology? With the development of manufacturing and technology, international specialization occurs. One country produces more modity than it uses itself and sells the remainder to other countries. 4. Explain the theory of absolute advantage and its application in international trade. It holds that modity will be produced in the country where it costs least in terms of resources (capital, land, and labor). This theory is illustrated in the following table. To be more illustrative, let us assume there are only two countries producing modities under petition. Output per man-year of labour Country A Country puters 50 10 Cars 20 40 From the above table, we can see that a man in Country A can produce puters in a year but only 10 in Country B. On the other hand, one man in Country B can produce 40 cars in a year but only 20 in Country A. So Country A is more efficient in puters than Country B, and we say the former has an absolute advantage over the latter in puters. Similarly, Country B has an advantage over Country A in producing cars. As a result, Country A would specialize in puters and trade some of them for Country B’s cars, and Country B would specialize in producing cars and exchange some of them for Country A’puters. Both countries will gain
