Paper 1 Q2
Sony launched the ‘PlayStation 5’ game console. As it was popular
among game players, long queues were found outside the shops
after the official release.
Which of the following would increase the opportunity cost of buying
a ‘PlayStation 5’ console?
A.
The resale value of ‘PlayStation 5’ increased due to its shortage.
B.
Retailers provided online purchase service to eliminate the queues
outside the shops.
With the same price, its competitor launched a new game console
featuring better performance than ‘PlayStation 5’.
The government issued electronic consumption coupons, which can
be used to purchase game consoles.
C.
D.

Paper 1 Q2
Different candidates chose to focus on different dimensions of
opportunity cost—i.e, the highest-value option forgone (better game
console being sold at the same price as PlayStation 5) or time cost
(queuing due to shortage).
The former picked Option C as the key. The latter picked either
Option A (lengthening of queues) or Option D (assuming PlayStation
5 is a normal good).

Paper 2-A1 comments
Q1a) Good.
Q1b) Satisfactory- Some only mentioned some factors
underlying a rise in production cost, rather than average
cost.
Q2) Satisfactory- Some failed to relate observations to
corresponding changes in the demand/supply of
riders/walkers, e.g.
Riders are able to deliver faster than walkers, so
their supply is larger.
Self-provided motorbikes could lower the cost of
production and result in a bigger supply of riders.
24
Paper 2-A1 comments
Q3a) Good.
- Some failed to use the comparatives (‘more’/‘less’) in the
answers.
Q3b) Good.
25
Paper 2-A1 comments
Q6a) Satisfactory.
- Some mistakenly assumed that output was constant and thus
arrived at a wrong conclusion.
- Regarding the definition of deflation, some made errors like
‘negative price level’ and ‘decreasing rate of growth of the price
level’.
Q6b) Fair.
- wrong sign associated with the ‘expected rate of inflation’ upon
rearrangement of terms in the Fisher equation
- omission of the keyword ‘expected’ in the deflation term
- confusing statement like ‘deflation (rate) is negative’
26
Paper 2-A1 comments
Q8a) Excellent.
Q8b) Good- stopped after obtaining the new level of money
supply without computing the level change.
27
Paper 2 Section A2 (Q4, 5, 7)
(a)
Verbal elaboration:
Imposition of tariff would result in a decrease in
the supply of imported goods.
Since the demand for imported goods is elastic,
the percentage decrease in quantity would be
bigger than the percentage increase in price.
Total expenditure would therefore drop.
(3)
Illustrate in the diagram:
- leftward shift in supply
- correct position of Area(+) and Area(−)
- Area(+) < Area(−)

32
Paper 2-A2 comments
Q4a) Satisfactory- Some wrongly compared the levelchanges in price and quantity instead of their percentagechanges or mistakenly assumed Country B to be a small
open economy or failed to show the leftward shift in its
supply curve as a result of the tariff.
33
Paper 2-A2 comments
Q4b) Satisfactory- common mistakes:
-failure to state clearly that the increase in the price of imports in
terms of local currency.
-wrong statement that the increase in the price of imports would
lead to a fall in the demand for imports.
-failure to distinguish between ‘total import value’ and ‘the
volume of imports’.
Q4c) Fair- Some managed to explain how devaluation might
affect Country B’s exports or imports of services.
-Some point out that net income from abroad or capital flows
may be affected, but failed to give proper reasons.
34
Paper 2-A2 comments
Q5a) Good.
- Some did not evaluate whether the STCGT was consistent
with those principles.
Q5b) Good.
- Some mixed up the definitions of positive statement and
normative statement.
- Some mistakenly defined a positive statement as one that can
be proven to be true by facts.
35
Paper 2-A2 comments
Q7a) Good.
- Some mistakenly assumed that output was constant and thus
arrived at a wrong conclusion.
- Regarding the definition of deflation, errors include ‘negative
price level’ and ‘decreasing rate of growth of the price level’.
Q7b) Satisfactory.
-failure to use the calculation in (a) to support their answer in (b).
-arguing that the statement was wrong instead of defending it.

Paper 2 Section B1 (Q9)

(b)
Verbal elaboration:
Better infrastructure would lead to an increase in
production capacity and potential output, and
thus an increase in long-run aggregate supply.
More infrastructure investment would lead to an
increase in aggregate demand. Aggregate
output would hence increase.

Paper 2-B1 comments
Q9ai) Good.
- Some misread the question as asking about the types of
factors of production.
-Some missed its connection with ‘nature’ in describing
primary production and merely stated that it involved
production of raw materials
Q9aii) Good.
Q9b) Good.
- failure to specify the reason behind an increase in AD
and/or LRAS.
- mistaking the value of output (i.e., price level times output,
P x Q) for aggregate output.

(e)
Verbal elaboration:
Demand for the courses increases. If the price
does not adjust fast enough in response to the
change in demand, then it would fall short of the
equilibrium price and thus result in excess
demand or shortage/queues.
(3)
Illustrate in the diagram:
- rightward shift of demand curve

Paper 2-B2 comments
Q10a) Satisfactory- some failed to identify the benefactor
and the beneficiary.
-some confused the definition of positive externality
(marginal social benefit > marginal private benefit) with its
inefficiency condition (marginal social benefit > marginal
social cost).
Q10b) Poor- failure to state accurately which two parties
and who is supposed to compensate whom.
- policies like tax or subsidy for market mechanism.
Q10c) Good- argued that (instead of division of labour)
better health is the reason for higher productivity.
45
Paper 2-B2 comments
Q10d) Excellent.
Q10e) Satisfactory.
- failure to label the demand-supply diagram properly (with
missing P, Q, S, D, excess demand).
- failure to identify the increase in demand and/or to state
the underlying reason.
- failure to mention shortage or excess demand in their
verbal explanation.
Q10f) Good.

Paper 2-B3 comments
Q11ai) Good. Some mistook it with the depression or even
recovery phase of business cycle.
Q11aii) Satisfactory- only a broad explanation for the
change in unemployment rate for the economy as a whole
(i.e., all industries).
- failed to compare the two given industries properly—due
to their lack of understanding about the nature of these
industries and/or to their confusing description (e.g., failing
to specify which particular industry they were talking about).
Q11b) Good- wrong statement that the sum should be
included in the calculation of government consumption
expenditure even if they realise it is a transfer payment.
59
Paper 2
Q11c) Satisfactory- some named ‘entry barriers’ or ‘imperfect
information’, which are not mentioned in Source C.
Q11d) Good- some failed to state accurately the function(s) of
money OR mistakenly quoted the properties of good money
(e.g., durability) in their answers.
60
Paper 2
Q11e) Satisfactory.
- Some presented their answers in separate paragraphs
and organised their ideas.
- Some explained the effects of Scheme C and Scheme H
in relation to the three objectives one by one, and then
compare their effects to come up with policy
recommendation under each objective.
- some misread the question and tried to analyse the
three objectives in one go, which resulted in a loss of
focus in their scheme comparison.
61
Paper 2
Objective 1:
- Some read the sources carefully, noting that there was
insufficient manpower in public hospitals, and concluded
that unemployment was not a big problem in the health
industry.
- Some discussed the overall unemployment rate only,
instead of unemployment in different industries.
- Some provided irrelevant answers such as dis-incentive
effect on labour caused by consumption vouchers and
use of unemployment-rate formula.
62
Paper 2
Objective 2:
- Some argued that the consumption vouchers (as
transfer payments aiming at boosting private
consumption) would not affect labour productivity.
- a few argued that (by improving workflow or increasing
capital per unit labour) the widespread use of electronic
payment method may improve labour productivity.
- mistaking an increase in employment in the retail/health
industry for an increase in labour productivity.
63
Paper 2
Objective 3:
- ability to apply their knowledge to analyse the effect on
aggregate output.
- failure to specify clearly whether they were talking about
the short run or the long run.
- mis-using the ‘short run and long run’ in economics and
‘short period of time and long period of time’
interchangeably.
- mis-reasoning that long-run aggregate supply would
increase whenever more workers are employed or
whenever the unemployment rate drops.

67
Paper 2 Overall comments
 Some candidates failed to demonstrate a thorough understanding of
basic economic concepts and principles, especially when applying them
to solve hypothetical or real-life problems.
Candidates should
strengthen their analytical skills instead of simply regurgitating concepts
and theories
 Some candidates lacked skills to extract information from tables and
graphs as well as to draw well-labelled diagrams. Candidates should
pay special attention to the headings, labels, and axes as they are
essential to our understanding of the data presented therein.
 Some candidates had difficulty in presenting their answers in a clear
and precise way. Candidates should equip themselves with better
language abilities as well as graphical skills, and make sure that their
handwriting is legible.
 Some candidates did not read the questions carefully.
Candidates
should devote special attention to the assumptions and conditions laid
down in the questions to avoid giving irrelevant answers.
 Some candidates did not seem to be well-informed about current
economic issues in the real world. Candidates should pay more
attention to economic news.
