The four macroeconomic aims
The four aims are: (1) economic growth — a sustained rise in real output, measured by real GDP (gross domestic product); (2) low and stable inflation — a slow, predictable price rise, measured by the CPI (consumer price index) or RPI (retail price index); (3) low unemployment; (4) a satisfactory BoP (balance of payments), avoiding persistent deficits. Aims can conflict: boosting growth may raise inflation; curbing inflation may raise unemployment.
GDP and its limitations
GDP (gross domestic product) is the total value of goods and services produced in a country in a year; real GDP adjusts for inflation to show growth. Benefits: internationally comparable, regularly updated, captures overall scale. Limitations: it ignores income distribution (inequality), excludes non-market activity and the informal economy, and ignores environmental damage. The HDI (human development index) adds health and education to income.
Measuring inflation; deflation
The CPI (consumer price index) tracks the average price of a household basket; the inflation rate is the yearly percentage change in CPI. The RPI (retail price index) also includes mortgage costs. Inflation erodes purchasing power and penalises savers. Deflation — a fall in the GENERAL price level — can make consumers postpone purchases, cutting AD (aggregate demand) in a deflationary spiral. Deflation is economy-wide, not one good's price falling.
Drawn from real examiner reports.
Deflation is economy-wide
Candidates give a MICRO definition of deflation — "the prices of goods are falling" — instead of a fall in the average (general) price level across the whole economy. A 2-mark "what is meant by" needs both parts: (1) a sustained FALL in (2) the average price level. "Prices falling" earns at most 1 mark; a single-product example earns zero.
November 2024 Paper 2, Q1(c): many candidates defined deflation as individual prices falling rather than the average price level falling — only partial or no credit awarded.
State the unit and the % sign
Calculation questions need three things: the correct value, the correct UNIT (% sign, or £bn for a revenue), and the right number of decimal places. A percentage-change-in-GDP (gross domestic product) answer that is right but drops the % sign or misrounds scores only 1 of 2. Show all working — a correct method with a wrong answer still earns 1 mark.
November 2024 Paper 2, Q4(a): candidates calculated percentage change in GDP correctly but omitted % sign or gave wrong decimal places — only 1 mark where 2 were available. June 2024 Paper 2, Q1(e): direct tax revenue calculation — omitting £bn cost the second mark.
Benefit vs limitation of GDP
Asked for a BENEFIT of using GDP (gross domestic product) to measure growth, some candidates gave a LIMITATION instead — a command-word slip. A benefit says why GDP is useful: international comparison, consistent frequent measurement, capturing the scale of output. Read whether the question wants a benefit or a limitation before answering.
November 2024 Paper 2, Q1(b): some candidates stated a limitation of GDP when the question asked for a benefit — misreading the command word/question focus.
GDP growth is not living standards
GDP growth does not automatically mean better living standards. Real GDP (gross domestic product) can rise while inequality widens or the environment is damaged. A higher average income says nothing about its distribution or wellbeing. The HDI (human development index) captures more by adding health and education to income.
Demand-pull vs cost-push inflation
Not all inflation comes from rising demand. Demand-pull inflation is when AD (aggregate demand) rises faster than supply. Cost-push inflation is when rising costs (wages, materials, energy) shift SRAS (short-run aggregate supply) left, raising prices without extra demand. Naming the wrong cause leads to the wrong policy.
CPI and RPI do not always agree
CPI and RPI do not always match. The CPI (consumer price index) excludes housing costs like mortgage interest; the RPI (retail price index) includes them, so RPI can be HIGHER than CPI when interest rates rise. Treating the two indices as identical, or assuming they always move together, loses precision in an inflation answer.
Analyse: develop one chain, no evaluation
On a 6-mark Analyse, AO4 (evaluation) earns no marks, so evaluation wastes time. Score by: (1) define the term, (2) apply it to the data, (3) develop the mechanism — e.g. higher costs, so investment falls, so unemployment may rise. Save both sides for Assess and Evaluate.
Define in two parts, no examples
A Define or "what is meant by" (2 marks) needs a TWO-PART answer and no examples. For deflation: (1) a sustained fall in (2) the general price level. An example given instead of a definition scores zero, and one part of two earns at most half.
Show working, unit and decimals
In a Calculate, show every step, state the unit (% or £bn) and round to the decimal places asked. A correct method with a wrong final figure still earns a method mark; a bare answer with no working risks everything. Never drop the % sign — it is worth a mark.
Match command word to the mark tariff
Match the command word to the tariff. State/Identify (1-2) = the fact only. Define (2) = a two-part meaning. Explain = define, apply, mechanism. Analyse (6-9) = one-sided chains. Assess/Evaluate (12) = both sides plus a supported judgement.
Governments pursue four main macroeconomic aims. These can conflict with one another, so policy always involves trade-offs.
| Aim | What it means | Key indicator |
|---|---|---|
| Economic growth | Sustained rise in real output | Real GDP (gross domestic product) growth rate |
| Low and stable inflation | General price level rising slowly and predictably | CPI (consumer price index) or RPI (retail price index) |
| Low unemployment | High proportion of labour force in paid work | Unemployment rate (%) |
