Question 11 mark
Correct option: B
1: B. The opportunity cost is the value of the next-best alternative forgone, here the earnings from working. A omits the forgone alternative; C includes every alternative rather than the best one; D ignores the non-monetary cost of time. A1 for B.Question 21 mark
Correct option: A
2: A. Scarcity arises because resources are limited relative to wants and have alternative uses. B confuses scarcity with a market price; C is not necessary for scarcity; D does not increase real resources or remove the underlying constraint. A1 for A.Question 31 mark
Correct option: C
3: C. Better technology increases productive capacity and shifts the boundary outward. A may move production inside the boundary; B changes nominal values, not capacity; D is a movement toward the existing boundary. A1 for C.Question 41 mark
Correct option: B
4: B. A higher price of Y makes X relatively more attractive if they are substitutes, raising demand for X. A predicts lower demand for X; C predicts no systematic cross-price effect; D concerns the income-demand relationship. A1 for B.Question 51 mark
Correct option: C
5: C. Marginal product is the change in total product: 132 - 100 = 32 units. A is average product at six workers; B divides total product by labour; D is total product. A1 for C.Question 61 mark
Correct option: C
6: C. Output rises proportionately more than all inputs, so returns to scale are increasing. A and B contradict the stated output response; D concerns changing one variable input while other inputs are fixed. A1 for C.Question 71 mark
Correct option: B
7: B. Average fixed cost is TFC divided by output: 500/10 = $50 and 500/20 = $25. A reverses the calculation; C ignores the larger denominator; D incorrectly treats fixed cost as disappearing. A1 for B.Question 81 mark
Correct option: A
8: A. When marginal cost is below average total cost, the additional unit costs less than the current average and pulls that average down. B reverses this relationship; C would require marginal cost to equal average cost; D confuses cost concepts. A1 for A.Question 91 mark
Correct option: C
9: C. A change in the good's own price causes movement along the demand curve, here a contraction in quantity demanded. A and B are shifts caused by non-price determinants; D concerns sellers. A1 for C.Question 101 mark
Correct option: B
10: B. Buyers compete for the limited quantity, creating upward pressure on price. A is the pressure associated with excess supply; C and D are not automatic consequences of excess demand. A1 for B.Question 111 mark
Correct option: A
11: A. Higher demand and lower supply both raise equilibrium price. Their quantity effects are opposite, so the net quantity change cannot be determined without magnitudes. B and C give unsupported directions; D assumes demand's quantity effect dominates. A1 for A.Question 121 mark
Correct option: B
12: B. Percentage change in quantity demanded is approximately PED times percentage change in price: -0.4 × 10% = -4%. A has the wrong sign; C inverts the elasticity incorrectly; D assumes unit elasticity. A1 for B.Question 131 mark
Correct option: B
13: B. Below-equilibrium price makes quantity demanded exceed quantity supplied, creating a shortage. The quantity actually exchanged is constrained by the smaller quantity supplied and falls. A describes a price floor; C ignores the supply constraint; D is false for a binding ceiling. A1 for B.Question 141 mark
Correct option: B
14: B. A single firm is too small to influence the market price when there are many sellers of a homogeneous product. A and C better describe market power; D is a barrier to entry, not a feature of perfect competition. A1 for B.Question 151 mark
Correct option: A
15: A. Entry gives consumers more close substitutes, reducing each existing firm's demand and tending to erode supernormal profit. B asserts an unrelated cost change; C is not implied by differentiation; D wrongly assumes products become identical. A1 for A.Question 161 mark
Correct option: B
16: B. Rivals are expected not to follow a price rise, causing a relatively elastic demand segment above the current price, but to match a price cut, causing a less elastic segment below it. A reverses the standard prediction; C and D do not generate the kink. A1 for B.Question 171 mark
Correct option: A
17: A. Long-run competitive equilibrium combines profit maximisation, P = MC, with free entry and exit eliminating economic profit, so P = minimum ATC. B implies market power or disequilibrium; C is not the competitive output condition; D describes a short-run shutdown-related condition, not long-run equilibrium. A1 for A.Question 181 mark
Correct option: B
18: B. The factory's production imposes an uncompensated external cost on third parties. A has the wrong sign; C concerns non-rivalry and non-excludability; D is a tax structure. A1 for B.Question 191 mark
Correct option: A
19: A. A corrective tax raises private cost toward social cost, discouraging excessive production and improving allocative efficiency if calibrated appropriately. B reverses the cost effect; C is not the tax's primary purpose and output would generally change; D describes a lump-sum rather than per-unit tax. A1 for A.Question 201 mark
Correct option: A
20: A. Progressivity means the average tax rate increases with income. B describes a fixed lump-sum payment; C is not the defining condition; D concerns expenditure rather than tax incidence. A1 for A.Question 211 mark
Correct option: B
21: B. Redistribution can narrow income disparities, improving equity, while taxes or transfers may alter work, saving or investment incentives. The magnitude and net welfare effect are empirical and policy-dependent. A makes an unjustified certainty; C assumes market outcomes are necessarily equitable; D ignores incentive effects. A1 for B.Question 221 mark
Correct option: A
22: A. GDP includes current production of final goods and services within the territory; a newly produced machine is current investment. B is an existing asset (though current brokerage services count); C is a transfer; D is unpaid non-market production. A1 for A.Question 231 mark
Correct option: A
23: A. Inflation rate = (104 - 100)/100 × 100% = 4%. B confuses the index level with the rate; C miscalculates the percentage change; D confuses index points with a percentage rate. A1 for A.Question 241 mark
Correct option: B
24: B. Per-capita growth is approximately real GDP growth minus population growth: 3% - 4% = -1%. A adds the rates; C reverses their order; D ignores their different growth rates. A1 for B.Question 251 mark
Correct option: A
25: A. Per-capita GDP is an average and does not reveal distribution, unpaid work, leisure, environmental quality or other dimensions of welfare. B is a strength of real rather than nominal GDP; C is incorrect; D is not necessarily true because total real GDP may grow faster than population. A1 for A.Question 261 mark
Correct option: A
26: A. The expenditure identity is C + I + G + (X - M). Imports are subtracted because they are included in expenditure but are not domestic production. B is not an expenditure identity; C omits major components and gives the trade term wrongly; D mixes income and transfer/stock concepts. A1 for A.Question 271 mark
Correct option: C
27: C. The multiplier is 1/(1 - MPC) = 1/0.2 = 5. The income change is 5 × 100 million. A ignores induced spending; B uses an incorrect multiplier; D multiplies by 20. A1 for C.Question 281 mark
Correct option: A
28: A. With spare capacity, higher autonomous spending raises aggregate demand and can increase real output through induced expenditure. B fits a fully constrained supply situation more closely; C reverses the demand effect; D ignores the multiplier and leakages. A1 for A.Question 291 mark
Correct option: A
29: A. Near capacity, supply is less able to respond with higher real output, so stronger AD is more likely to put upward pressure on the price level. B reverses the demand effect; C ignores capacity constraints; D assumes no response. A1 for A.Question 301 mark
Correct option: A
30: A. Imported inputs become more expensive, raising production costs and shifting short-run aggregate supply left; this is cost-push pressure. B confuses a cost shock with stronger aggregate demand; C gives the opposite cost and supply effects; D is unrelated. A1 for A.Question 311 mark
Correct option: C
31: C. Money as a unit of account provides a common measure for stating and comparing prices. A concerns payment in transactions; B concerns holding purchasing power; D concerns settling future obligations. A1 for C.Question 321 mark
Correct option: A
32: A. Lending can create a deposit, which is part of the money supply; the extent is constrained by capital, liquidity, risk, regulation and demand for loans. B reverses the initial deposit effect; C confuses deposit money with notes; D does not follow because the loan creates an asset and deposit liability, not necessarily matching reserves. A1 for A.Question 331 mark
Correct option: B
33: B. Under the linked exchange rate, interest-rate and monetary conditions are constrained by the commitment to maintain convertibility and the exchange-rate link. A overstates independent discretion; C ignores differences in economic structures and shocks; D incorrectly claims the money supply cannot change. A1 for B.Question 341 mark
Correct option: A
34: A. Higher interest rates raise borrowing costs and the return to saving, tending to reduce interest-sensitive consumption and investment. B reverses the opportunity-cost effect; C is not the usual interest-rate channel; D gives the wrong saving incentive. A1 for A.Question 351 mark
Correct option: A
35: A. Falling real activity and rising unemployment indicate recessionary pressure. B is associated with excess demand and rising prices; C is unrelated and not definitional; D concerns productive capacity, not necessarily current output. A1 for A.Question 361 mark
Correct option: A
36: A. Government purchases directly increase AD and can generate further induced spending, especially with spare capacity. B misclassifies government purchases as a leakage; C confuses current demand with an immediate equal increase in productive capacity; D makes unsupported claims. A1 for A.Question 371 mark
Correct option: B
37: B. Progressive tax receipts fall as income falls without a new policy decision, supporting disposable income relative to the downturn. A and C require discretionary decisions; D is a structural regime change, not an automatic stabiliser. A1 for B.Question 381 mark
Correct option: B
38: B. Lower government expenditure or higher taxes and higher interest rates reduce components of AD, easing demand-pull inflation but risking lower output and employment. A, C and D are generally expansionary and could add to AD. A1 for B.Question 391 mark
Correct option: A
39: A. Retraining and matching address the skills or location mismatch underlying structural unemployment. B targets cyclical demand deficiency more directly; C raises the cost of hiring; D worsens labour mobility and mismatch. A1 for A.Question 401 mark
Correct option: B
40: B. Well-selected infrastructure may improve productivity and potential output, but project appraisal must compare social benefits with resource and financing costs. Near full employment, additional spending can also crowd out private use of resources or add inflationary pressure; existing debt makes financing relevant. A and D assert unjustified guarantees; C overlooks investment as aggregate demand. A1 for B.Question 411 mark
Correct option: B
41: B. A's opportunity cost of one rice is 0.5 textile, compared with B's 1 textile, so A has comparative advantage in rice. A's cost of one textile is 2 rice, compared with B's 1 rice, so B has comparative advantage in textiles. A and C confuse absolute productivity with comparative advantage; D is false. A1 for B.Question 421 mark
Correct option: A
42: A. In a small country, the world price is given; the tariff raises the domestic price, encouraging domestic supply and reducing domestic demand, so imports fall. B reverses the effects; C mistakes price-taking internationally for no domestic price effect; D confuses domestic policy with world supply and ignores efficiency losses. A1 for A.Question 431 mark
Correct option: B
43: B. Appreciation raises the foreign-currency price of Hong Kong exports and lowers the Hong Kong-dollar price of imports, other things equal. A reverses both effects; C does not distinguish the buyer's currency; D ignores relative-price effects. A1 for B.Question 441 mark
Correct option: B
44: B. A current-account deficit means current-account debits exceed credits. Its implications depend on causes, financing, sustainability and the wider economy. A confuses the fiscal and external balances; C refers only to goods and gives the wrong necessary condition; D is false because balance-of-payments accounts have offsetting financial flows and other entries. A1 for B.Question 451 mark
Correct option: B
45: B. Depreciation makes exports relatively cheaper and imports dearer. Elastic export demand allows a comparatively large quantity response, while inelastic import demand limits its short-run reduction; contract and price adjustments can delay improvement in the trade balance, producing a possible J-curve. A overstates certainty and mishandles values; C reverses the likely export response; D ignores trade-price effects. A1 for B.
