#THE PROBLEM THIS SOLVES

You enter Section D with 25 minutes. You see Q13 and Q14. You read both. One feels more familiar. You choose it and start writing. This is the wrong process. Familiarity is not the selection criterion. Preparation quality is.

Students who choose based on familiarity and then discover mid-essay that they cannot name two distinct mechanisms, do not have country data, or cannot write the "only if" sentence — lose 4–8 marks. The question that felt less familiar but for which you had strong preparation would have scored higher.

This document gives you a 90-second decision framework that eliminates wrong question choice.

#THE THREE-TEST DECISION FRAMEWORK

Apply all three tests to BOTH questions before committing. 90 seconds maximum.

#TEST 1 — THE TWO MECHANISMS TEST

"Can I name two genuinely distinct economic mechanisms for this question — mechanisms that compete rather than support each other?"

Write in your margin in 5 words:

Q13: [mechanism 1] vs [mechanism 2]
Q14: [mechanism 1] vs [mechanism 2]

PASS: Two different mechanisms, different chains, opposing conclusions possible. FAIL: You can only think of one mechanism, or both mechanisms go in the same direction.

Why this matters: If you pass Test 1 on Q14 and fail on Q13, choose Q14 regardless of topic familiarity. An essay with one mechanism is Level 2 KAA regardless of content quality — maximum approximately 12/20.

Examples of genuine bilateral mechanisms:

Topic	Chain 1	Chain 2 (competing)
Monetary policy	Rate rise → borrowing cost → C falls → disinflation	Rate rise → exchange rate appreciation → CA deteriorates
Supply-side	Education → human capital → LRAS → non-inflationary growth	Time lag + electoral cycle → LRAS shift never materialises
Fiscal policy	G rise → multiplier → AD → growth	Crowding out → I falls → AD reduced → net effect limited
Inflation costs	Competitiveness → CA deteriorates → growth slows	Uncertainty → investment falls → LRAS constrained
Exchange rates	Depreciation → export competitiveness → CA improves	Depreciation → import costs → SRAS left → stagflation
Recession	Income loss → living standards fall → multiplier worsens	Hysteresis → NAIRU rises → structural unemployment permanent

#TEST 2 — THE DATA TEST

"Do I have a specific country, specific figure, AND specific year for at least one chain in each question?"

Write in your margin in 3 words:

Q13 data: [country] [figure] [year]
Q14 data: [country] [figure] [year]

PASS: You have at least one: country + figure + year. The figure can be from the extract (always available) or own knowledge. FAIL: You have a country name but no figure. You have a figure but no year. You have no data at all.

Why this matters: No data = context ceiling = Level 3 KAA maximum = maximum approximately 9/12 KAA = maximum approximately 15/20. One specific figure with year unlocks Level 4. The difference is one sentence.

The extract data lifeline: If you pass Test 1 on both questions but fail Test 2 on one, remember — the extract country's data is always available for any question. If the extract is about India and Q14 is about monetary policy, you can use India's 4.4%→4.9% base rate rise as your own-country data even if you chose India as your Section C country.

Own-country data to memorise (usable on any question):

UK: base rate 0.1%→5.25% (2021-2023); CPI 11.1% (Oct 2022); 
    GDP −9.9% (2020), +7.4% (2021); furlough £70bn
South Korea: rate 1.25%→3.5% (2022-2023)
Japan: productivity 30% below USA (2022)
Egypt: rate 21.25%→27.25% (2024); pound −35% (2023)
India: rate 4.4%→4.9% (2022); unemployment 7.1%→8.5% (2023)
Brazil: Gini 0.49; GDP +4.99% (2021)
World: GDP doubled + emissions +32% (2000-2023)

#TEST 3 — THE CONDITION TEST

"Can I write the 'only if' sentence for this question right now, from memory, in under 10 seconds?"

Mental test only — do not write: Think of the core "only if" condition for each question. If you cannot, your judgement will be unconditional — Level 2 evaluation cap regardless of chain quality.

PASS: You can state the condition immediately. It is specific and tied to this topic. FAIL: You know you need "only if" but cannot produce the specific condition from memory.

Pre-memorised conditions by topic:

Monetary policy: "only if inflation is predominantly demand-pull"
Supply-side: "only if investment is sustained 15-20 years across electoral cycles"  
Fiscal policy: "only if negative output gap exists AND monetary policy accommodates"
Inflation costs: "only if inflation is unanticipated and unindexed"
Exchange rates: "only if Marshall-Lerner condition (PED(X)+PED(M)>1) satisfied in LR"
Recession: "only if recession is prolonged enough for hysteresis (4+ quarters)"
Unemployment: "only if unemployment is structural not cyclical"
Growth: "only if growth is broadly distributed AND supply-led not demand-led"
Objective conflicts: "only if growth remains fossil-fuel-intensive"

#THE DECISION MATRIX

Result	Action
Pass all 3 tests on BOTH questions	Choose the topic you are most comfortable with — both will score well
Pass all 3 on Q14, fail one on Q13	Choose Q14 — regardless of topic preference
Pass all 3 on Q13, fail one on Q14	Choose Q13
Fail Test 1 on one question	Eliminate that question immediately — one mechanism = Level 2 KAA maximum
Fail Test 2 on one question	Use extract data as fallback before eliminating
Fail Test 3 on both questions	Write "only if [the condition from T3-12/T3-10/T3-11]" from memory — the condition banks in the topic master briefs are memorisable
Fail multiple tests on both questions	Choose the question where you fail the LEAST critical test — Test 1 failure is most damaging

#WORKED EXAMPLES — APPLYING THE FRAMEWORK

Scenario 1: Q13: "Evaluate the costs of inflation in an economy of your choice." Q14: "Evaluate the use of fiscal policy as a means of increasing economic growth."

Test 1:

Q13: competitiveness (CA) vs investment uncertainty (LRAS) → PASS both mechanisms
Q14: G → multiplier → AD vs crowding out → PASS both mechanisms

Test 2:

Q13: UK CPI 11.1% (Oct 2022) + Egypt 27.25% rate → PASS
Q14: UK furlough £70bn (2020) + GDP −9.9%/+7.4% → PASS

Test 3:

Q13: "only if inflation unanticipated" → PASS
Q14: "only if negative output gap AND monetary accommodation" → PASS

Result: Both pass all three. Choose the topic you are more confident developing at Stage 5 depth.

Scenario 2: Q13: "Evaluate the likely macroeconomic effects of a persistent current account deficit." Q14: "Evaluate whether supply-side policies are more effective than demand-side policies at reducing unemployment."

Test 1:

Q13: financing risk (hot money exit) vs CA deficit reflects strong demand (not always bad) → PASS
Q14: supply-side (NAIRU reduction) vs demand-side (output gap closure) → PASS

Test 2:

Q13: UK CA deficit 3-4% GDP → PASS; Egypt CA deficit driven by inelastics → PASS
Q14: South Korea NAIRU / Japan 30% productivity gap → PASS; UK furlough cyclical employment preservation → PASS

Test 3:

Q13: "only if capital inflows that finance the deficit are volatile" → PASS
Q14: "only if unemployment is structural (supply-side effective) vs cyclical (demand-side effective)" → PASS

Result: Both pass. Choose Q14 — comparison questions ("more effective than") allow clearer bilateral structure and cleaner conditional judgement. Unless current account is your stronger content area.

Scenario 3 (under time pressure): Q13: "Evaluate the causes of inflation in an economy of your choice." Q14: "Evaluate the effects of economic growth on the macroeconomic objectives of an economy."

Test 1 — Q13: demand-pull (AD excess) vs cost-push (SRAS shift) → PASS Test 1 — Q14: growth → inflation (positive output gap) vs growth → environment (emissions) → PASS Test 2 — Q13: UK CPI 11.1% (demand-pull) + Turkey 80%+ → PASS Test 2 — Q14: world GDP doubled + emissions +32% → PASS; South Korea growth + Gini → PASS Test 3 — Q13: "only if demand-pull dominant" → PASS Test 3 — Q14: "only if growth is fossil-fuel-intensive" → PASS

Both pass. Choose based on depth: Q13 has cleaner mechanism chains (demand-pull vs cost-push are genuinely competing). Q14 requires juggling multiple objectives which can make the bilateral structure less tight. For time-pressured situations, Q13 is the safer structure.

#THE ONE-SENTENCE SUMMARY

Choose the question where you can pass all three tests — two mechanisms, one data point, one condition. If both pass, choose the cleaner bilateral structure. If neither passes, choose the one where you fail the least damaging test (Test 2 failure is most recoverable; Test 1 failure is least recoverable).

#REFERENCE CARD — PRINT OR MEMORISE

TEST 1: Can I name 2 genuinely competing mechanisms?
         Fail → Level 2 KAA max → eliminate

TEST 2: Do I have country + figure + year?
         Fail → use extract data as fallback
         Still fail → Level 3 KAA max (−3 marks)

TEST 3: Can I write "only if [condition]" now?
         Fail → Level 2 eval max (−2 to −4 eval marks)
         → check condition bank (T3-10 to T3-34)

CHOOSE: All 3 pass both → structural preference
        1 fails on one → eliminate that question
        Both struggle → least damaging failure
