This guide follows the OCR A Level Economics (H460) specification, Version 3.0 (June 2026), for first assessment in 2021. It covers Component 03, Themes in economics. The specification prescribes no content of its own for this component: it draws on the microeconomic and macroeconomic content and applies it to a specific unseen theme. The text does not label any of it as AS or Extension. There is one examination series each year, in May/June. The countries, firms and figures below are made up.

Track progress with the OCR Economics hub, the printable checklist and the free diagnostics. Then use the revision notes and the practice questions. The content itself is in the microeconomics and macroeconomics pages, and the exam preparation page gives a general routine.

What this guide covers

Outcome What you must be able to do
Analyse an unseen theme Use the theme’s own stimulus and apply content from any part of the course
Link micro and macro Show how market-level ideas and whole-economy ideas connect, in both directions
Quantitative skills Use ratios, percentages, averages, index numbers, graphs, money-to-real conversions, elasticity, cost, revenue and profit
Multiple-choice technique Answer 30 questions drawn from across the course
Extended response Write sustained, linked, evaluated answers
Think as economists Show AO1 knowledge, AO2 application, AO3 analysis and AO4 evaluation

1. What the specification says about Component 03

The specification states these facts, and they set how you prepare.

Feature Official statement
Weight One of three components, each 33.33% of the A level
Paper 2 hours, 80 marks, written
Section A A series of 30 multiple-choice questions, drawn from across micro and macro, mainly AO1 and AO2 with some AO3 and AO4
The rest Short answer and extended response questions on an unseen theme, 50 marks in total
Question sizes Low-tariff questions up to 4 marks; extended responses from 8 up to 25 marks
Advised timing About 40 to 45 minutes on the multiple choice, 15 to 20 minutes reading the stimulus, about 60 minutes on the 50 marks
Quantitative skills At least 20% of the overall assessment marks, across the three components

The 80 marks less the 50 marks on the theme leave 30 marks for the 30 multiple-choice questions. The specification says each extended writing question requires you to draw on different aspects of the micro and macro content and to demonstrate the links between them. It describes synoptic assessment as the explicit drawing together of knowledge, skills and understanding, so that you treat economics as one discipline and not a set of unrelated topics.

2. Analysing an unseen theme

You cannot learn the theme in advance, so learn a method. Read the stimulus once for the story, then again with a pen.

  1. Name the setting. Which market, which country, which time frame?
  2. List the actors. Households, firms, government, foreign buyers and sellers. What does each want?
  3. Find the shock. What changed? A price, a cost, a policy, a population, a technology?
  4. Sort the evidence. Underline figures and mark each as micro (one market) or macro (whole economy).
  5. Pick two or three models. Choose the ones the evidence supports, not every model you know.
  6. Build the chain, then judge. Trace cause to effect, then decide what matters most and why.

Worked example: an invented theme

Theme: the rapid growth of app-based delivery work in Country R (illustrative). Between year 1 and year 3 the stimulus reports the following.

Item Year 1 Year 3
Delivery riders 40,000 52,000
Rider pay per hour (cu) 9.00 9.45
Consumer price index 100 108
Delivery fee per order (cu) 3.00 3.60
Orders per week 100,000 88,000
Unemployment rate 6.0% 5.4%

Step 4 gives the figures to work out.

Rider growth      = (52,000 - 40,000) / 40,000 x 100 = 30.0%
Nominal pay rise  = (9.45 - 9.00) / 9.00 x 100        = 5.0%
Real pay (yr 1 prices) = 9.45 / 108 x 100             = cu 8.75
Real pay change   = (8.75 - 9.00) / 9.00 x 100        = -2.78%
%change fee       = (3.60 - 3.00) / 3.00 x 100        = +20%
%change orders    = (88,000 - 100,000) / 100,000 x 100 = -12%
PED               = -12 / 20                           = -0.6
Revenue from fees = 3.00 x 100,000 = 300,000 -> 3.60 x 88,000 = 316,800 (+5.6%)

Now the chain. Micro: demand for delivery is price inelastic (PED of -0.6, so its size is below 1), so a higher fee raised platform revenue. That revenue supports the derived demand for riders. Entry is easy, so labour supply is highly elastic and pay is held down. Macro: 30% more riders and a fall in unemployment of 0.6 percentage points suggest higher employment and output. Real pay fell by 2.78%, so rider spending power did not rise with employment. Link back: lower real pay among workers who spend most of their income limits the growth of consumption, a component of aggregate demand.

Your judgement then needs a criterion. For example: the gain to the economy depends on whether new riders were previously unemployed or were switching from better-paid jobs, and on whether the fall in real pay is permanent.

3. Linking micro and macro

A link is a causal statement that crosses the boundary. Practise both directions.

Micro to macro Macro to micro
Firms in many markets face higher costs, so short-run aggregate supply shifts left A rise in interest rates raises the cost of borrowing for one firm and lowers investment there
Inelastic supply in one market (housing) pushes prices up and feeds into the price index A fall in aggregate demand cuts demand in markets with high income elasticity most
Market failure (pollution, information failure) lowers the sustainability of growth A higher exchange rate cuts the price of imported inputs but squeezes exporters’ revenue
Monopoly power and low competition reduce productivity growth Fiscal austerity cuts spending on a merit good, so provision falls below the socially efficient level

Good links name the mechanism. “Unemployment rises” is a statement. “Falling demand for the good means firms cut output, which lowers their demand for labour, so unemployment rises and household income falls, reducing consumption further” is a link.

Suppose the delivery boom raises rider incomes and leads to extra spending of cu 8 million in Country R. Leakages are the marginal propensities to save (0.15), tax (0.15) and import (0.10).

Marginal propensity to withdraw = 0.15 + 0.15 + 0.10 = 0.40
Multiplier = 1 / 0.40 = 2.5
Change in national income = 8 million x 2.5 = cu 20 million

If a larger share of spending goes on imports so that the propensity to withdraw is 0.5, the multiplier is 1 / 0.5 = 2 and the rise is cu 16 million. So a micro fact (where riders spend) alters a macro result.

4. Quantitative skills across components

The specification lists these skills: ratios and fractions; percentages and percentage changes; mean, median and relevant quantiles; standard graphical forms; index numbers; cost, revenue and profit (total, average, marginal); money to real terms; elasticity and its interpretation; and interpreting information in written, graphical and numerical form. Show formulas first, then working, then a sentence of meaning.

Worked example: cost, revenue and profit

A small bakery sells 600 loaves a day at cu 2.50 and has average total cost of cu 2.10.

Total revenue = 2.50 x 600 = 1,500
Total cost    = 2.10 x 600 = 1,260
Profit        = 1,500 - 1,260 = 240

Energy costs cu 0.30 per loaf, and energy rises 40%: extra cost = 0.30 x 0.40 = cu 0.12 per loaf. New average cost is 2.22, total cost 1,332 and profit 168. Profit falls by 72/240 = 30%. This is the micro side of cost-push inflation.

Worked example: percentage points and index numbers

Employment in a region has an index of 115 in year 2 and 130 in year 3 (year 1 = 100). The rise is 15 index points. The percentage change is (130 - 115) / 115 x 100 = 13.0%. Do not report the points as a percentage.

Worked example: mean and median

Five riders earn (cu a week) 220, 240, 250, 260 and 530. The mean is 1,500 / 5 = 300 and the median is 250. One high value pulls the mean up, so the median says more about a typical rider.

5. Multiple-choice technique

The 30 multiple-choice questions come from across the course, mainly testing knowledge and application and sometimes analysis and evaluation.

  • Cover the options, work out your own answer, then look for it.
  • For calculations, do the working in the margin. Check units, and whether the answer is a percentage, a number of points or a ratio.
  • Eliminate options that break a definition (for example, a normal good with a negative income elasticity).
  • Watch for “real” and “nominal”, for “falls” and “falls by less”, and for “per cent” versus “percentage points”.

Example. Nominal GDP rises by 7% and the price level rises by 4%. What is the growth in real GDP? Real growth is 1.07 / 1.04 - 1 = 0.0288, so about 2.9%. Subtracting the rates gives 3%, which is only a rough approximation, so a close option such as 3% can be a trap when the exact figure is 2.9%.

6. Extended response and thinking as an economist

The four assessment objectives are AO1 knowledge, AO2 application, AO3 analysis and AO4 evaluation. On this component they carry 9%, 9%, 8.33% and 7% of the qualification marks respectively. Use them as a checklist for each paragraph.

Objective In an answer
AO1 Define the term and name the model or concept accurately
AO2 Use the theme’s own data, markets and actors
AO3 Link cause to effect in stages, including across micro and macro
AO4 Weigh arguments with evidence and reach a supported judgement

A model paragraph

Question stem: “Assess the effects of a rise in energy prices on Country B.”

“Energy is an input for most firms, so higher prices raise costs of production. Because demand for energy is price inelastic in the short run (here PED = -0.2), firms cannot cut their use quickly, so the percentage fall in their usage is smaller than the percentage rise in price, and spending on energy rises. This lowers profit margins and encourages firms to raise prices, shifting short-run aggregate supply left, which raises the general price level and reduces real output. However, the effect depends on how large energy is in total costs and whether the rise is temporary.”

The paragraph names a concept, applies it, chains it to a macro result, and ends with a qualification. Practise these in your own words.

Common errors

  • Writing a general essay on a topic instead of using the stimulus.
  • Treating micro and macro as separate halves, so that links are asserted and not explained.
  • Reporting percentage points as percentages, or nominal values as real values.
  • Evaluating with “it depends” and no explanation of what it depends on.
  • Drawing a diagram and never referring to it in the text.
  • Ignoring time: short run and long run often reverse a conclusion.
