第 1 題1 分
正確答案: C
1: C. Opportunity cost is the highest-valued option forgone. Ken can take only one of the alternatives, so it is the $450 from private tuition (3 × $150). A is the lower-valued alternative; B is the difference between the two jobs; D adds both alternatives. The ticket being free does not make the cost zero, because queuing takes time.第 2 題1 分
正確答案: C
2: C. (1) is correct: a free good involves no sacrifice of alternatives. (2) is wrong: a free gift such as a lunch box uses scarce resources, so it is an economic good. (3) is correct: whether a good is free depends on whether the quantity available is more than enough to satisfy all wants at zero price, which varies by place.第 3 題1 分
正確答案: C
3: C. A positive statement can be refuted by facts, whether or not it is true. (1) and (3) can be checked against data. (2) contains the value judgement 'should', so it is normative.第 4 題1 分
正確答案: D
4: D. Full cost = money price + time cost. Queuing is non-price competition, so customers with a higher value of time bear a higher full cost. A is wrong: the price is not used to ration tables. B is wrong: the owner still decides how the tables are used. C is wrong: the queue decides 'for whom to produce'.第 5 題1 分
正確答案: A
5: A. One more viewer watching a programme does not reduce the amount available to others, so the programmes are non-rivalrous in consumption, i.e. public goods. Being free of charge does not make a good public or free; the programmes are economic goods produced with scarce resources.第 6 題1 分
正確答案: D
6: D. Training raises the quality of labour and better machines raise output per worker. In (2), once marginal product falls below average product, hiring more workers lowers the average product of labour.第 7 題1 分
正確答案: D
7: D. Geographical mobility is the ease with which workers move between places of work. Lower commuting costs make it easier to take jobs in other districts. A affects occupational mobility; B lowers occupational mobility; C reduces the incentive to move.第 8 題1 分
正確答案: C
8: C. Tertiary production provides services. A is primary production; B and D are secondary production (manufacturing and construction).第 9 題1 分
正確答案: B
9: B. Marginal products are 10, 14, 12, 8 and 4 loaves. The marginal product first falls when the 3rd worker is employed (from 14 to 12).第 10 題1 分
正確答案: B
10: B. The marginal costs of the 5th, 6th, 7th and 8th units are 22, $26 and $32. The firm produces as long as MC ≤ price, i.e. 6 units. Profit = 6 × 120 = $30. C ignores the fixed cost.第 11 題1 分
正確答案: A
11: A. The flour mill is at an earlier stage of the same production chain, so the merger is backward vertical integration. It secures the supply of flour.第 12 題1 分
正確答案: A
12: A. Internal economies of scale arise from the expansion of the firm itself, such as bulk purchasing. B and C are external to the firm; D is not related to the scale of production.第 13 題1 分
正確答案: D
13: D. Both have many sellers and free entry and exit. Firms in monopolistic competition sell differentiated products and are price searchers, so (1) is not common to both.第 14 題1 分
正確答案: C
14: C. Imported mooncakes are substitutes, so a rise in their price increases the demand for Hong Kong-made mooncakes. A causes a movement along the demand curve; B affects supply; D decreases demand.第 15 題1 分
正確答案: B
15: B. Higher wages raise costs and decrease supply; more online orders increase demand. Both changes raise the price, but they have opposite effects on quantity, so the change in quantity is uncertain.第 16 題1 分
正確答案: D
16: D. A fall in the supply of petrol raises its price and lowers its quantity transacted (3). Since cars and petrol are in joint demand, the demand for cars falls (1), lowering their price (2).第 17 題1 分
正確答案: B
17: B. With inelastic demand, the percentage fall in quantity demanded is smaller than the 10% rise in price, so total expenditure increases.第 18 題1 分
正確答案: D
18: D. More close substitutes make consumers more responsive to a price change. A, B and C all make demand less elastic.第 19 題1 分
正確答案: C
19: C. Qd = 130 − 5P and Qs = 10P − 20. After the tax, Qs = 10(P − 3) − 20. Equilibrium: P = $12 and Q = 70. Tax revenue = $3 × 70 = 2 more per unit and sellers receive $1 less, so sellers bear $1 per unit.第 20 題1 分
正確答案: B
20: B. An effective price ceiling is set below the equilibrium price, so quantity demanded exceeds quantity supplied (1) and buyers compete by other means such as queuing (2). The quantity transacted falls to the quantity supplied, so (3) is wrong.第 21 題1 分
正確答案: D
21: D. An effective quota restricts quantity below the equilibrium level, so price rises (1) and consumer surplus falls (2). At the quota, marginal benefit exceeds marginal cost, so there is a deadweight loss (3).第 22 題1 分
正確答案: C
22: C. A minimum wage below the equilibrium wage is not effective. If effective, it lowers the quantity of labour demanded and causes a surplus of labour, not a shortage. It does not affect workers already paid above it.第 23 題1 分
正確答案: C
23: C. Ann buys a ticket as long as her marginal benefit is at least 80 − 60 − 60. B wrongly includes the 3rd ticket, whose marginal benefit is below the price.第 24 題1 分
正確答案: A
24: A. The pollution is a negative externality, so marginal social cost exceeds marginal private cost. The factory produces where MPC = MB, which is beyond the efficient output where MSC = MSB, so there is over-production and a deadweight loss.第 25 題1 分
正確答案: B
25: B. The tax lowers the quantity transacted below the efficient level, where marginal benefit equals marginal cost, so it creates a deadweight loss. Producer surplus falls; the change in total expenditure depends on the elasticity of demand.第 26 題1 分
正確答案: D
26: D. Larger transfers to low-income households narrow the income gap and lower the Gini coefficient. A and B make the tax system less progressive and C reduces in-kind benefits to the poor; all widen the gap.第 27 題1 分
正確答案: D
27: D. The agent's commission is payment for a service produced in the current period. A is a transaction of a good produced in the past; B is a transfer payment; C is non-market production, which is excluded.第 28 題1 分
正確答案: B
28: B. By the value-added approach, the total value added is the value of the final product minus imported inputs: 50 = 100 + (100) + (250 − 450. D double counts intermediate goods.第 29 題1 分
正確答案: A
29: A. GNI = GDP + factor income from abroad − factor income paid abroad = 200bn, so (1) is correct and the net flow is positive, so (3) is wrong. GDP at factor cost = 150bn + 2 670bn (2).第 30 題1 分
正確答案: A
30: A. Growth rate of real GDP ≈ growth rate of nominal GDP − growth rate of the GDP deflator = 5% − 3% = 2%.第 31 題1 分
正確答案: A
31: A. Peter is available for and seeking work, so he is unemployed. Unemployment that arises while workers search for or move between jobs is frictional unemployment.第 32 題1 分
正確答案: B
32: B. By Fisher's equation, the actual real interest rate = 3% − 4% = −1%, below the expected 1%. As a lender, Mrs Ho loses and the bank, as the borrower, gains from the unanticipated inflation.第 33 題1 分
正確答案: C
33: C. Spending by inbound tourists is an export of services, a component of aggregate demand. A causes a movement along the AD curve; B and D shift AD to the left.第 34 題1 分
正確答案: A
34: A. Higher input prices raise the costs of production and shift the SRAS curve to the left, so the price level rises and real output falls.第 35 題1 分
正確答案: D
35: D. More working-age immigrants increase the labour force and the full-employment output. A shifts the SRAS curve; B and C shift the AD curve.第 36 題1 分
正確答案: B
36: B. Using money to express and compare the values of goods is its function as a unit of account.第 37 題1 分
正確答案: B
37: B. Savings deposits are in M2 and M3 but not in M1. Both cash held by the public and demand deposits are in M1, so M1 rises by HK$100 000 (1). M2 and M3 include all three items, so they remain unchanged (2), and (3) is wrong.第 38 題1 分
正確答案: C
38: C. Required reserves = 10% × 200m, so excess reserves are 100m × 1/10% = $1 000m. D is the maximum total deposits.第 39 題1 分
正確答案: A
39: A. Selling Hong Kong dollars for US dollars increases the Aggregate Balance, part of the monetary base (1). More liquidity tends to push down interbank rates (2). The strong-side Convertibility Undertaking keeps the rate from going beyond 7.75, so (3) is wrong.第 40 題1 分
正確答案: A
40: A. A direct tax is one whose burden cannot be shifted to others, such as salaries tax and profits tax. Stamp duty is levied on transactions and is an indirect tax.第 41 題1 分
正確答案: A
41: A. A higher allowance lowers salaries tax payments and raises disposable income, increasing aggregate demand. B is a monetary change; C and D are contractionary fiscal policies.第 42 題1 分
正確答案: B
42: B. Country A produces more of both goods per unit of resources (1). The opportunity cost of 1 cloth is 2 rice in A and 4 rice in B, so B has a comparative advantage in rice and exports it (2). Mutually beneficial terms of trade must lie between 2 and 4 rice per cloth, so (3) is wrong.第 43 題1 分
正確答案: B
43: B. The tariff raises the domestic price of Good X, so domestic producers supply more, consumers buy less and imports fall. Consumer surplus decreases.第 44 題1 分
正確答案: C
44: C. The tourist's hotel spending is an export of services, recorded in the current account. A and B are financial account transactions; D changes the official reserve assets, which are also recorded in the financial account.第 45 題1 分
正確答案: C
45: C. Each Hong Kong dollar buys more yen, so goods priced in yen are cheaper in Hong Kong dollars. Hong Kong goods become dearer in yen, so B and D are wrong; A is the opposite of the effect.
