#PURPOSE

This bank compiles confirmed indicative content from Pearson WEC12 mark schemes across all 21 series (Jan 2019–Oct 2025). Points on this list are those the principal examiner identified before standardisation. Writing any of these points earns confirmed AO1/AO3 credit.

#MONETARY POLICY — INDICATIVE KAA + EVAL

KAA (confirmed in multiple mark schemes):

• Base rate rises → borrowing cost rises → C and I fall → AD leftward → demand-pull CPI reduces
• Base rate rises → capital inflows → exchange rate appreciates → import prices fall → cost-push reduces
• Base rate rises → asset prices fall → negative wealth effect → spending falls → AD leftward
• QE → asset prices rise → positive wealth effect → consumer confidence rises → C rises → AD rightward
• Rate cuts → borrowing cost falls → C and I rise → AD rightward → output gap closes → cyclical unemployment falls
• Context ceiling: maximum Level 3 if no extract or own-country data embedded

Confirmed evaluation content:

• Effectiveness conditional on whether inflation is demand-pull or cost-push
• Time lag 12–18 months: may overtighten before effect materialises; policy uncertainty
• Near-zero lower bound: rate cuts cannot go negative without unconventional policy
• Exchange rate appreciation: disinflationary but worsens export competitiveness
• Confidence trap: "pushing on a string" if balance sheet repair dominates spending
• Confirmed condition: "holds only if inflation is predominantly demand-pull in origin"

#SUPPLY-SIDE POLICY — INDICATIVE KAA + EVAL

KAA (interventionist):

• Education → human capital → productivity → unit costs fall → LRAS rightward → Yfe rises → non-inflationary growth
• Infrastructure → TFP rises → LRAS rightward → SRAS rightward → dual price and output effect
• R&D subsidies → innovation → TFP → LRAS rightward → trend growth rate rises
• Addresses market failure (positive externality in education; public good infrastructure)

KAA (free market):

• Labour deregulation → hiring costs fall → NAIRU falls → structural unemployment reduces
• Income tax cuts → labour supply rises → output rises
• Privatisation → competition → efficiency → SRAS rightward
• Corporation tax cuts → investment rises → LRAS rightward over time

Confirmed evaluation content:

• Interventionist: 15–20 year time lag; electoral cycle commitment problem; deadweight loss risk in R&D subsidy
• Free market: only works if regulatory burden is primary constraint; cannot replace market failures
• Confirmed condition: "holds only if the binding constraint on growth is [market failure / regulatory burden]"

#FISCAL POLICY — INDICATIVE KAA + EVAL

KAA (expansionary):

• G rises → AD = C+I+G+X−M → multiplier → AD rightward → output rises → cyclical unemployment falls
• Tax cuts → disposable income rises → C rises → AD rightward → output rises
• Capital expenditure → AD + LRAS simultaneously (dual mechanism)
• Most effective with large negative output gap and accommodating monetary policy

Confirmed evaluation:

• Crowding out: deficit → yields rise → I falls → net AD effect reduced
• Ricardian equivalence: households anticipate future tax → save the transfer → C does not rise
• Fiscal multiplier >1: spending cuts paradoxically widen deficit
• Time lags: recognition + implementation + impact
• Confirmed condition: "only if monetary policy accommodates" and "only if negative output gap exists"

---

#INFLATION COSTS — INDICATIVE KAA + EVAL

KAA:

• Inflation > trading partners → real appreciation → export competitiveness falls → X−M worsens → CA deteriorates
• Inflation uncertainty → investment falls → I component of AD falls → LRAS growth constrained
• Real purchasing power of fixed incomes erodes → living standards fall
• Wage-price spiral: inflation → wage demands → unit costs rise → further inflation
• Menu and shoe leather costs (less significant at moderate rates)

Confirmed evaluation:

• Anticipated inflation with full indexation minimises real costs
• Hyperinflation >> moderate inflation in severity
• Confirmed condition: "holds only if inflation is unanticipated or poorly indexed"

---

#RECESSION COSTS — INDICATIVE KAA + EVAL

KAA:

• Real incomes fall → C falls → multiplier → further contraction (self-reinforcing)
• Automatic stabiliser: welfare rises + tax falls → fiscal deficit widens → policy capacity constrained
• Investment collapses → LRAS permanently constrained
• Hysteresis: skills deterioration → cyclical converts to structural → NAIRU rises permanently

Confirmed evaluation:

• Brief recessions: primarily temporary costs, limited hysteresis
• Prolonged recessions: permanent NAIRU rise, investment pipeline depleted
• Self-correcting mechanism: excess labour supply → wage flexibility → SRAS rightward in long run
• Confirmed condition: "holds only if recession is prolonged enough for hysteresis to operate (12+ months elevated unemployment)"

---

#UNEMPLOYMENT EFFECTS — INDICATIVE KAA + EVAL (Oct 2024/Jun 2021)

Workers:

• Income loss → living standards fall
• Skills deterioration → human capital erodes → earning capacity permanently reduces
• Social costs (mental health, family, crime) — examiner: "Award for well-developed social impacts"
• Underemployment: skilled workers in below-qualification roles

Public finances:

• Welfare rises automatically
• Income tax falls (taxpayers → non-taxpayers)
• VAT and corporation tax fall (consumption and profits contract)
• Fiscal deficit widens → counter-cyclical capacity constrained

CEILING RULE (verbatim): "Award maximum Level 3 for answers considering only ONE category (workers OR public finances)."

---

#OBJECTIVE CONFLICTS — INDICATIVE KAA + EVAL

Confirmed conflict pairs:

• Growth ↔ inflation: SRPC (UK 3.5% unemployment + 11.1% CPI 2022)
• Growth ↔ environment: world GDP doubled + emissions +32% (2000–2023)
• Growth ↔ equality: Brazil Gini 0.49 persists despite +4.99% recovery 2021
• Inflation ↔ current account: domestic inflation → real appreciation → X−M worsens

Confirmed evaluation:

• Growth-inflation resolvable via supply-side NAIRU reduction
• Growth-environment: partial decoupling confirmed; holds only if fossil-fuel-intensive
• Growth-equality: resolvable with redistribution (South Korea Gini 0.42→0.31)

CEILING RULE (verbatim): "Award maximum Level 3 for answers considering only ONE conflict."

#LEVEL DESCRIPTORS — VERBATIM

KAA Level 2 (4–6/12): "Application evident but not developed. Chains of reasoning evident but may not be developed fully or some stages omitted."

KAA Level 3 (7–10/12): "Application developed to good effect. Chains of reasoning clear and well developed."

KAA Level 4 (11–12/12): "Accurate and precise knowledge. Analysis clear, coherent, focused. Logical and multi-stage chains of reasoning."

Eval Level 2 (2–4/8): "Evaluative statements with some link to analysis but weak or superficial judgement."

Eval Level 3 (5–8/8): "Well reasoned evaluative statements, conditional judgements supported by evidence."

---

#CONTEXT CEILING — EXACT WORDING

Confirmed in every 20-mark and 14-mark mark scheme 2019–2026:

"Award a maximum of Level 3 for KAA where the candidate's response fails to include any contextual data, either from the extract or from their own-country knowledge."

One specific figure unlocks Level 4 KAA. The figure must be embedded in the argument, not stated as a standalone sentence.
