Participating actively in international organisations and conferences to promote international trade Short Questions Country A imports Good X and exports Good Y.
Suppose the world price of Good X is lower than the domestic price of Good X in Country A under autarky. With the help of TWO diagrams, compare the situation without trade and the situation with trade and show the gains from trade. Do all domestic consumers and domestic producers benefit from trade? (8 marks) b**. Suppose the world price of Good Y is higher than the domestic price of Good Y in Country A under autarky. With the help of TWO diagrams, compare the situation domestic consumers and domestic producers benefit from trade? 8 marks) With the help of a diagram, illustrate why the imposition of a quota would benefit domestic producers but harm domestic consumers and bring a deadweight loss to an economy. (8 marks) Structured Questions Trade Organization, China has to reduce its tariff on cotton. Suppose the world price f cotton remains unchanged after the tariff reduction. a. With the help ofa diagram, illustrate how the reduction in the tariff affects the domestic price, domestic consumption, domestic production and volume of imports of cotton. (7 marks) b.
How does the tariff reduction affect the consumer surplus, producer surplus, government revenue and total social surplus? (5 marks) a. Compare the effects of an increase in domestic demand on the domestic price, domestic consumption, domestic production and volume of imports if a country imposes a tariff and a quota on its imports, respectively. 12 marks) b. Would consumers prefer a tariff or a quota in the above situation? (2 marks) Answers p. 150 1. They mainly want to cut the volume of imports so as to protect their domestic industries. Moreover, imposition of duties on imported goods may raise government revenue. . The imposition of duties will raise the domestic price of imported goods, reduce the volume of imports, lower the consumer surplus of domestic consumers, but increase the producer surplus of domestic producers. 3. Many of Hong Kongs imports do not have domestic substitutes, e. g. , water, food, raw materials. Moreover, the image of a free port facilitates Hong Kong’s negotiation with its trading partners to reduce their trade barriers. On the whole, free trade brings more benefit than harm to Hong Kong. p. 151 Discuss 12. 1 After tariffs are imposed, the domestic prices of imports rise.
By the law of demand, people will buy fewer units of imports. After the imposition of quotas, the maximum quantities of imports allowed are smaller than the equilibrium quantities. As a result, the quantities of imports will drop. As people buy fewer units of imports, they buy more units of domestic goods as substitutes for imports. Hence, domestic industries are protected. p. 154 Discuss 12. 2 No. With free trade, domestic prices drop and domestic consumption rises. As a result, the consumer surplus increases, as illustrated by Area (C + E) in Fig. 12. 3.
Hence, domestic consumers of imports gain. However, domestic prices drop and domestic production falls. As a result, the producer surplus decreases, as illustrated by Area C Therefore, free trade does not benefit everybody. However, on the whole, as consumers’ gains are greater than producers’ losses, the total social surplus increases, as illustrated by Area E in Fig. 12. 3. Test Yourself 12. 1 At domestic prices below (Pw + t), since the price cannot cover the cost [i. e. the world price (PW) plus tariff (t)], importers are not willing to supply the good.
Only domestic producers with MC domestic price will supply. This portion of the supply curve is represented by line segment ae. Since the domestic economy is a small open economy, it cannot affect the world price (PW) no matter how many units it imports. At the domestic price of (Pw + t), since the price can cover the (constant) cost, importers are willing to supply as many units as consumers desire without raising the price. Even if demand increases, the domestic price will not rise above (Pw + t). Hence, the supply curve turns horizontal at Point e (represented by line segment eg).
