Paper 2
Section A
1.a.The value of being a teacher.(2 marks)
b.If students are more obedient, it means the value of being a teacher increases. Therefore, Samuel’s cost of being an accountant increases. (2 marks)
c.When Samuel buys clothes now, he has to pay interest, which can be used for future consumption. Thus, interest is the cost of earlier availability of goods in this case.
(2marks)
2.a.i.Capital(1 mark)
ii.Capital(1 mark)
ii.Labour(1 mark)
b.Possible reasonsinclude:
•Complex organisation of the expanded restaurant may delay decisions, block communication and weaken coordination.
•The restaurant may expand its scale through borrowing. Lenders may charge the restaurant a higher interest rate when the restaurant’s loans increase.
•The supply of some inputs is limited. When the restaurant continuously increases its inputs, it may have to purchase inputs from more expensive sources or use costlier substitutes.
(Any TWO of the above or other reasonable answers.2 marks × 2 = 4 marks)
c.Features (of monopolistic competition) include:
•Large number of sellers
•Free entry
•Heterogeneous products
•Imperfect information
•Price searching behaviour
•Both price and non-price competition may occur
(Any TWO of the above or other reasonable answers.1 mark × 2 = 2 marks)
3.The law of diminishing marginal returns states that when a variable factor is added continuously to a given quantity of fixed factors, the marginal return or marginal product (of the variable factor) will eventually decrease, ceteris paribus. (2 marks)
The data illustrate the law as the marginal product decreases.(1 mark)
Machines (units) / Marginal output (units)1 / 100
2 / 110
3 / 115
4 / 100
(2 marks)
4.Indicate in the diagram:
•Decrease in the demand for digital cameras(1 mark)
•Decrease in the quantity transacted and price of digital cameras(1 mark)
•Original producer surplus (Area abe) > New producer surplus (Area cde)(1 mark)
Verbal elaboration:
The price of memory cards increases as the sales tax decreases the supply of memory cards. (1 mark)
The demand for digital cameras decreases as memory cards are a complement of digital cameras. (1 mark)
Both the price and quantity transacted of digital cameras decrease. As a result,the producer surplus decreases from Area abe to Area cde. (2 marks)
5.When parallel traders gather at the MTR stations to divide up and distribute their goods, they only consider their private costs. (1 mark)
However, their activities adversely affect other MTR users and residents nearby, such as blocking their way and worsening the environmental hygiene in nearby areas. (1 mark)
Since parallel traders do not compensate the parties who are adversely affected, their activities impose an external cost on other people. As a result, there is a divergence between private and social costs. (2 marks)

ii.Percentage change in money supply = $200/$100 = +200%(1 mark)
According to the quantity theory of money,the percentage change in nominal GDPmust be equal to the percentage change in money supply (+200%);thusthe percentage change in nominal GDP is +200%. (2 marks)
c.The monetary policies include:
•Buying government bonds from the market
•Lowering the discount rate

(Accept other reasonable answers with explanation.2 marks × 2 = 4 marks)
11.a.Indicate in the diagram:
A vertical money supply curve shifts rightwards.(1 mark)
Nominal interest rate decreases while the quantity of money increases.(1 mark)
Verbal elaboration:
When the central bank buys securities from banks, currency flows from the central bank to the market. Hence, the monetary base increases. (1 mark)
The money supply will increase and the money supply curve shifts from MS1 to MS2. (1 mark)
Nominal interest rate decreases from n1 to n2 while the quantity of money increases from M1 to M2. (2 marks)
b.i.Indicate in the diagram:
•The aggregate demand curve shifts rightwards.(1 mark)
•Real GDP and price level increase (in the short run).(1 mark)
Verbal elaboration:
Under the linked exchange rate system, depreciation of the US dollar will cause the Hong Kong dollar to simultaneously depreciate by a similar percentage.
(2 marks)
When the Hong Kong dollar depreciates against other foreign currencies, the quantity of Hong Kong’s exports will increase while the quantity of Hong Kong’s imports will decrease. As real net exports increase,aggregate demand (AD) increases. (2 marks)
The aggregate demand curve will shift rightwards. As a result,both Hong Kong’s real GDP and price level will increase in the short run. (2 marks)
ii.As the Hong Kong dollar depreciates against other foreign currencies,the domestic prices of Hong Kong’s imports will increase. (1 mark)
According to the law of demand,Hong Kong’s quantity demanded of imports will decrease. (1 mark)
The change in total value of imports in terms of Hong Kong dollars is uncertain, depending on the price elasticity of demand for imports. (2 marks)
12.a.i.Country X’s cost of producing 1 bread = (5/10)candies = 1/2 (or 0.5)candies
(2 marks)
Country Y’s cost of producing 1 bread = (8/12)candies = 2/3 (or 0.67) candies
(2 marks)
ii.Country Y(1 mark)
because it has a comparative disadvantage in producing bread / its cost of producing bread is higher. (1 mark)
b.i.The maximum gain from trade = (2/3 – 1/2)candies = 1/6 (or 0.17)candies
(1mark)
Thus, the range of the passage fee(in terms of candies):
0 < Passage fee < 1/6 (or 0.17).(1 mark)
ii.Thepassagefee imposes a per unit fee on the goods traded.(1mark)
According to the law of demand,as the relative price of high-quality goods decreases, more consumers would likely buy high-quality goods. (1 mark)
Therefore, the quality of goods traded will be higher.(1 mark)
Section C
13.a.Wecan obtain the following information:
Output / Quantity demandedper day (units) / Marginal cost($) / Price($) / Marginal revenue ($)
1 / 16 / 20 / 20
2 / 16 / 19 / 18
3 / 16 / 18 / 16
4 / 16 / 17 / 14
5 / 16 / 16 / 12
6 / 16 / 15 / 10
Correct indication of marginal revenue at respective output level(2 marks)
Inthe perfectly competitive market, the output level will be 5 units where the market price = marginal cost = $16. (2 marks)
In the monopoly, with simple monopoly pricing, the profit-maximising output level will be 3 units where marginal cost = marginal revenue = $16. The profit-maximising price will be $18. (2 marks)
b.The marginal benefit of the third unit of the good to consumers ($18) exceeds the marginal cost of producing that unit ($16). (1 mark)
Therefore, total social surplus can be increased by increasing output / there are potential gains not being captured / there is deadweight loss. (1 mark)
c.Price discrimination is a practice of charging different price to different buyers for the same good for reasons other than differences in costs. (2 marks)
The arrangementconstitutes price discrimination.
Reason:VIPcustomers and non-VIP customers are charged different prices for the same good. / Customers who want to become VIP members are more sensitive to price changes and so have higher demand elasticity. As a result, they are charged a lower price. (2 marks)
OR
The arrangementdoes not constitute price discrimination.
Reason: All customers facethe same price schedule. Different customers pay different prices because they consume different amounts of the good. / Due to economies of scale, the average cost of serving customers with higher consumption levels may be lower. The lower price may only reflect a lower production cost. (2 marks)
(Any ONE of the above stands with reasonable explanation.)
d.Examples of vertical agreement:
•Exclusive dealing
•Exclusive territory
•Resale (or retail) price maintenance
•Quantity discounts
•Tie-in sales or product bundling
•Long-term supply contracts
(Any TWO of the above.1 mark × 2 = 2 marks)
e.Arguments against competition policy:
•Increasing business costs: It is costly to fulfil the requirements of a competition policy.

ii.Country B has a comparative advantage in producing clothing(1 mark)
because Country B’s cost of producing 1 unit of clothing (0.67units of food) is lower than that of Country A (2units of food) / the slope of Country B’s PPF is flatter than that of Country A. (2 marks)
b.i.No. Point G is not available for Country A’s consumption.(1 mark)
Because Point G lies outside of Country A’s PPF.(1 mark)
ii.Yes. Point G is available for Country A’s consumption.(1 mark)
Country A can produce 20 units of food, and export 10 units of food for 10 units of clothes to attain Point G. (2 marks)
