AQA AS Economics — Macroeconomics
8 Model 25-Mark Essays (Top-Band Standard), Annotated by Assessment
Objective
Scope: AS macroeconomics (Paper 2, The national economy in a global context), covering
economic growth, inflation, unemployment, fiscal/monetary/supply-side policy, exchange rates,
the balance of payments, and globalisation. Nothing here goes beyond AS depth — no Phillips
curve, no formal Marshall–Lerner naming, no A-level-only content.
How to read the annotations
Each essay is broken into its assessment-objective parts so you can see exactly what earns
marks:
• Knowledge (AO1) — accurate definitions and economic theory.
• Application (AO2) — linking theory to the real economy or to a context.
• Analysis (AO3) — developed chains of cause-and-effect reasoning, supported by a
diagram.
• Evaluation (AO4) — supported judgements: “this depends on…”, weighing, prioritising.
This is the objective that decides your level, so it appears in every body paragraph and in
the conclusion.
On diagrams: in the exam you hand-draw these. Where a diagram belongs, the essay tells you
precisely what to draw in [Diagram: …] — draw it and refer to it in your prose, because an
unreferenced diagram earns little.
Why these reach Level 5: the AQA 25-mark grid awards Level 5 (21–25) for sound, accurate
analysis on both sides plus evaluation that is supported throughout, leading to a supported
conclusion. Every essay below defines terms precisely, builds both sides, evaluates inside each
paragraph (not just at the end), and closes with a criterion-based judgement that answers the
exact wording. A brief Examiner check after each confirms spec-alignment, accuracy and
appropriate (not excessive) AS depth.
Essay 1: Income tax cuts and economic growth
Evaluate the view that cuts in income tax are the most effective way of increasing
economic growth. [25 marks]
Spec area: fiscal policy; aggregate demand; economic growth (actual vs potential).
Diagram: AD/AS.
Introduction — Knowledge + line of argument
Economic growth is an increase in the real output (real GDP) of an economy over time; it is
useful to distinguish actual growth (using up existing spare capacity) from potential growth (an
increase in the economy's productive capacity). A cut in income tax is an instrument of
expansionary fiscal policy. The phrase “most effective” requires a comparison with alternatives,
, so this essay argues that income tax cuts can raise actual growth in the short run but are rarely
the most effective route to sustained growth, with their effectiveness depending heavily on the
size of the output gap and on whether growth is actual or potential.
Argument 1
Analysis (AO1/2/3): A cut in income tax raises households' disposable income. Since
consumption is the largest component of aggregate demand (AD = C + I + G + (X − M)), higher
disposable income raises consumer spending, shifting AD to the right. Through the multiplier,
the eventual rise in AD is larger than the initial injection, as one person's spending becomes
another's income. [Diagram: AD/AS with AD shifting right from AD₁ to AD₂; real GDP rises from
Y₁ to Y₂.] This is a rise in actual growth as firms raise output to meet demand.
Evaluation (AO4): The size of this effect depends critically on the output gap and the position
on the AS curve. With substantial spare capacity (a negative output gap, the flat region of a
Keynesian AS curve), higher AD raises real output with little inflation. Near full capacity,
however, the same rise in AD mainly raises the price level, so “growth” is largely nominal. The
effect also depends on the marginal propensity to consume: if households save the tax cut
rather than spend it (a high propensity to withdraw), the multiplier is small and the boost to
growth is weak — likely during periods of low confidence.
Argument 2
Analysis (AO1/2/3): Income tax cuts can in principle raise potential growth too, through a
supply-side incentive effect: lower income tax increases the reward from working, which may
encourage longer hours, greater labour-market participation and effort, raising the supply of
labour and shifting LRAS to the right. [Diagram: AD/AS with LRAS shifting right, raising potential
output.]
Evaluation (AO4): This incentive effect is empirically weak and uncertain — many workers
cannot vary their hours, and the income effect may offset the substitution effect. The dominant
impact of an income tax cut is therefore a one-off, demand-side boost rather than a lasting rise
in capacity. Policies that directly raise productivity — investment in education, training and
infrastructure — are more reliable routes to sustained growth, which weakens the claim that tax
cuts are “most effective”.
Argument 3 — Evaluation (AO4)
Tax cuts also carry costs that bear on their effectiveness. They worsen the government's budget
position, requiring borrowing that may raise interest rates and crowd out private investment, and
they carry an opportunity cost, since the same revenue could fund growth-enhancing
investment. Fiscal policy also acts with time lags, and faster demand-led growth can worsen
inflation and the current account as imports rise. These trade-offs mean an income tax cut is
rarely a clean win for growth.
Conclusion — Evaluation (supported judgement)
Cuts in income tax can be an effective way of raising actual growth, but only under specific
conditions: a recessionary economy with spare capacity and a high marginal propensity to
consume. They are not the most effective way of achieving sustained growth, because they
primarily boost AD rather than capacity; supply-side measures that raise productivity are
