What this dot point is asking

OCR wants you to explain the basic economic problem, define and apply opportunity cost, identify the four factors of production and their rewards, and distinguish positive statements (testable claims of fact) from normative statements (value judgements). These ideas underpin the whole specification.

The basic economic problem

Scarcity forces three fundamental questions on every economy: what to produce, how to produce it, and for whom to produce. Different economic systems answer these questions in different ways, but no system escapes the underlying problem. Scarcity is not the same as a shortage: a shortage is a temporary excess of demand over supply at a given price, whereas scarcity is the permanent condition that wants exceed the means to satisfy them.

Opportunity cost

Opportunity cost is a real cost even when no money changes hands. A student who spends an afternoon revising forgoes the leisure they could have enjoyed; a government that uses land for a hospital forgoes the housing it could have built there. Rational economic agents are assumed to weigh the benefit of a choice against its opportunity cost, choosing only when the expected benefit exceeds the next best alternative.

The factors of production

Output is produced by combining four factors of production, each of which earns a factor reward.

  • Land: all natural resources (fields, minerals, fish stocks). Reward: rent.
  • Labour: human physical and mental effort. Reward: wages.
  • Capital: man-made aids to production (machinery, factories, software). Reward: interest.
  • Enterprise: the entrepreneur who organises the other three factors and bears the risk of production. Reward: profit.

The quantity and quality of these factors set an economy's productive potential. Improving them, for example by training labour or investing in capital, is how an economy grows over time.

Positive and normative statements

The distinction matters because policy debates mix the two. Economists can use positive analysis to predict the effects of a policy, but whether the policy is desirable is normative and depends on the value placed on the outcomes. Recognising which is which keeps analysis rigorous and exposes hidden assumptions.

Examples in context

  • Government budgets. Every Budget is an exercise in opportunity cost: extra NHS funding may mean less for defence or higher borrowing, a trade-off the Office for Budget Responsibility scrutinises.
  • Time as a scarce resource. A-Level students ration revision time across subjects; the opportunity cost of an extra hour on economics is the marks forgone in another subject.
  • Land use. Using green-belt land for housing forgoes its environmental and recreational value, the core of many planning disputes.

Q1. Define opportunity cost and give one example for a government. [3 marks]

  • Cue. Next best alternative forgone; example such as spending on healthcare forgoing spending on education.

Q2. Explain, with an example, the difference between a positive and a normative statement. [4 marks]

  • Cue. Positive is testable against evidence; normative is a value judgement (ought or should); contrast a factual claim with a should claim.

Exam-style practice questions

Practice questions written in the style of OCR exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

OCR H460/01 20194 marksA farmer with 200 hectares earns a contribution of £900\pounds 900 per hectare from wheat and £1,100\pounds 1{,}100 per hectare from oilseed rape, but agronomic limits mean at most 120 hectares can grow rape. The farmer maximises contribution. Calculate the opportunity cost, in lost contribution, of the land that cannot be switched to rape.
Show worked answer →

A short calculate question testing opportunity cost as the next best alternative forgone.

The farmer puts the 120 best hectares into rape and the remaining 80 hectares into wheat. The 80 hectares of wheat earn 80×£900=£72,00080 \times \pounds 900 = \pounds 72{,}000. Had those 80 hectares been able to grow rape they would have earned 80×£1,100=£88,00080 \times \pounds 1{,}100 = \pounds 88{,}000. The opportunity cost of being unable to switch that land is the forgone extra contribution, £88,000−£72,000=£16,000\pounds 88{,}000 - \pounds 72{,}000 = \pounds 16{,}000.

Markers reward (1) identifying opportunity cost as the next best forgone use, (2) the correct subtraction, and (3) the answer with units. A common slip is to report the full £88,000\pounds 88{,}000 rather than the difference.

OCR H460/01 202210 marksDiscuss whether opportunity cost is always a useful concept for a government deciding how to allocate a fixed health budget.
Show worked answer →

A levels-of-response question (roughly knowledge and application, analysis, then evaluation). Define opportunity cost as the next best alternative forgone, and apply it: spending on one treatment (say a cancer drug) means forgoing the next best use (more hip operations or mental-health services), so the concept forces explicit prioritisation and underpins tools such as the cost per QALY.

Analyse why this is useful: it makes trade-offs visible, supports allocative efficiency, and discourages treating any spending as free.

Evaluate the limits: outcomes are uncertain and hard to value, equity and political factors matter alongside efficiency, and some benefits (dignity, prevention) resist measurement, so opportunity cost informs but does not settle the decision. Conclude with a supported judgement, for example that it is necessary but not sufficient.
