PART B: SHORT-ANSWER QUESTION (75 MARKS)
• Show all workings.
• Round your answers to two decimal places.
• Fully label your graphs, if you are required to draw one.
B1. (24 marks)
Suppose that fixed costs for a firm in the truck manufacturing industry (start-up costs of factories,
automation chain, etc.) are $1.25 billion, and that variable costs are $1,000 per finished truck. Suppose
is determined by the equation 𝑃𝑃 = 1,000 + 𝑛𝑛 , where n represents the number of firms in the market.
Assume that there are three countries in the world: England, Scotland, and Wales, with the market size being 300 million, 250 million, and 100 million, respectively.
a. (5 marks) Calculate the equilibrium number of firms in the truck market in England in autarky. b. (3 marks) What is the equilibrium price and the average cost of trucks in England if there is no
international trade?
c. (5 marks) Now suppose that the three countries join to form a free trade area named LUKMOFTA (literally-the-UK-minus-one-FTA), and assume no transportation costs. How many firms will there be in the combined market? What will be the new equilibrium price, and average cost for each truck?
d. (5 marks) Suppose instead that after a referendum, Scotland leaves the free trade area, so that the free trade area now only consists of England and Wales. At the same time, there is a breakthrough in trucking technology, reducing a firm’s fixed cost to $800 million. Calculate the new number of firms, the equilibrium price, and average cost for each truck in this combined market.
e. (6 marks) Compare the number of firms and the price that English consumers pay for each truck between the scenarios in (b), (c) and (d). In which scenario would English consumers benefit the most? Explain why.
that the truck market is monopolistically competitive, and firms are identical. Suppose the market price
B2. (15 marks)
Assume two countries, Home and Foreign, with two factors of production, capital and labour, used to produce two goods, rice and cloth. Technology is the same in two countries. Cloth production is labour intensive; Foreign is capital abundant. Suppose that Home is large, while Foreign is small.
a. (5 marks) Suppose Home imposes a tariff on its imports, following an optimal tariff schedule, and Foreign counters by applying an export subsidy, so that in the end, relative prices in Foreign are unchanged. What happens to the terms of trade and the overall welfare of the two countries? Explain your answer, using a relative demand-relative supply curve graph to support your answer.
b. (6 marks) Explain out of each country’s producers, consumers, and the government, who win/lose from both the tariff and the subsidy from both countries.
c. (2 marks) Given your answer in part (b), why does Foreign imposes the export subsidy?
d. (2 marks) Instead of an export subsidy, what can Foreign do to counter Home’s action and keep its
overall welfare as close to the level before Home imposes the tariff as possible?
B3. (10 marks)
a. (5 marks) Suppose there are three countries: Australia, Britain, and Canada. Suppose that trade between Australia and its two trading partners follow the gravity equation between Australia and its trading partner 𝑖𝑖, where 𝑖𝑖 can be either Britain or Can𝐷𝐷ada:
𝑇𝑇𝐴𝐴𝐴𝐴 = 5 × 𝑌𝑌𝐴𝐴3 × 𝑌𝑌𝐴𝐴2
Suppose that Britain’s GDP is 1.5 times as high as Canada’s GDP, but the distance between Britain and Australia is twice as high as the distance between Australia and Canada. Which would be larger: the trade volume between Australia and Britain, or the trade volume between Australia and Canada, and by how many times?
b. (5 marks) Why can a country consume outside its production possibilities frontier when it engages in international trade? Draw a graph and refer to it in your explanation.
B4. (18 marks)
Consider a model with three countries: Austria, Bavaria, and Czechia. The demand and supply equations
a. (3 marks) What is the price of beer in Austria? How many units of beer (pints) will Austria import, and how much tariff revenue will the Austrian government collect?
Suppose now that Austria signs a free trade agreement (FTA) with Bavaria. Use this information to answer parts (b) to (e).
b. (3 marks) How many units of beer (pints) will Austria import, and from which country?
c. (3 marks) Is this the case of trade creation or trade diversion as a result of Austria forming an FTA
with Bavaria? Explain why.
d. (7 marks) Plot the demand-supply curve of the beer market in Austria. Calculate the total welfare gain/loss to Austria as a result of the Austria-Bavaria FTA.
e. (2 marks) Can Czechia complain about the removal of tariff between Austria and Bavaria to the WTO? Why or why not?
B5. (8 marks)
Assume Australia, a large country, exports wine and imports cars. Recently climate change has resulted in very wet weather, reducing wine production in Australia, and increasing the world price of wine relative to cars.
a. (4 marks) Explain how this can reduce the welfare of Australia, using the production possibility frontier and indifference curve graph to support your answer.
b. (4 marks) While the normal conclusion is that Australia loses out from the severe weather, that is not always the case. In fact, Australia can instead experience a gain in welfare from this event. Explain how, using the production possibility frontier and indifference curve graph to support your answer.
for beer in Austria follows
𝐷𝐷𝐴𝐴 = 120 − 1.4𝑃𝑃𝐴𝐴, 𝑆𝑆𝐴𝐴 =2+0.6𝑃𝑃𝐴𝐴,
where 𝐷𝐷𝐴𝐴, 𝑆𝑆𝐴𝐴 refer to quantities demanded and supplied in Austria at the price 𝑃𝑃𝐴𝐴, respectively. The unit cost of beer production is $45 in Bavaria, and $28 in Czechia. Currently, there is a 100% tariff on beer imports into Austria. Assume that there are no transportation costs.
