1.1.2 Positive and Normative Statements

Economists argue about the minimum wage constantly. Some of that argument can be settled with evidence, and some of it cannot. Telling those two things apart is what this topic is about, and it is one of the most reliably useful distinctions in the whole A-Level.

Positive statements

A positive statement is a claim about how the world is. It can be tested against evidence and shown to be true or false.

• Raising the minimum wage to £13 an hour would reduce employment among 18 to 20 year olds.
• UK inflation was 3.4% in the year to August.
• A rise in the price of coffee reduces the quantity of coffee demanded, ceteris paribus.

Note the second and third points carefully.

Watch out: A positive statement does not have to be true. "UK inflation was 40% last year" is still a positive statement: it is wrong, and the fact that we can show it is wrong is precisely what makes it positive. Positive means testable, not correct.

Positive statements can also be about the future, as long as evidence could in principle settle them. A forecast is positive; a wish is not.

Normative statements

A normative statement is a claim about how the world should be. It rests on a value judgement — a view about what matters, what is fair, or what the priority ought to be. No amount of data settles it, because people with the same data can hold different values.

• The minimum wage should be raised to £13 an hour.
• Inflation of 3.4% is unacceptably high.
• The government ought to tax wealth more heavily than income.

The usual giveaways are should, ought, must, fair, unfair, too high, too low, better, worse. But don't rely on word-spotting alone, because a statement can be packed with accurate data and still end in a judgement. "With inflation at 3.4% and wages rising by only 2%, the Bank of England must cut interest rates" is normative, despite two accurate figures, because must is doing the work.

Why the distinction matters for policy

Economic policy always needs both. Evidence tells you what a policy would probably do; values tell you whether that outcome is desirable.

Take a sugar tax. Positive economics can estimate how much consumption would fall, who would pay most of the tax, and what revenue it would raise. None of that decides whether the tax should exist. That depends on how you weigh a child's future health against the freedom of an adult to buy what they want, and on whether you think a tax that falls hardest on low-income households is acceptable.

Key idea: This is why economists working from similar evidence still disagree about policy: the disagreement is usually about values rather than about the evidence itself.

Value judgements also hide inside things that look purely technical. Choosing to target inflation rather than unemployment is a judgement about which matters more. Measuring poverty as 60% of median income is a judgement about what counts as poor.

Key terms

Common mistakes

• Thinking positive means true. A false but testable claim is still positive.
• Word-spotting instead of reading. A sentence full of statistics can still be normative. Ask what the sentence is doing: describing, or recommending?
• Calling a forecast normative. "Growth will slow next year" is a positive claim about the future, testable in time.
• Spotting a normative statement without identifying the judgement inside it. The useful step is naming the competing values at stake — whose interests are being weighed against whose.

How this has been examined

In the Edexcel papers indexed on this site, this topic has appeared in two formats:

• A 1-mark multiple-choice question (asked once, 2021).
• A 5-mark "Explain" data-response question (asked twice, in 2019 and 2023).

Where this goes next

This follows directly from 1.1.1 Economics as a social science, where the limits of economic evidence are set out. It then underpins 1.4.1 Government intervention in markets, where the case for intervening rests on both evidence and values, and 2.6.1 Possible macroeconomic objectives, where choosing between conflicting objectives is itself a value judgement.
