What this dot point is asking
SEAB wants you to distinguish positive statements (objective, testable claims about what is) from normative statements (value judgements about what ought to be), and to explain the role value judgements play in economic analysis and policy. The central insight is that economics as a science can establish facts and predict effects, but choosing a policy always also involves judgements about what is desirable.
The answer
Positive statements
A positive statement is objective: it describes what is, was, or will be, and can in principle be tested against evidence. It can be shown to be true or false by looking at the facts.
- "A 10 percent rise in the price of cigarettes reduces quantity demanded by 4 percent."
- "Unemployment rose last quarter."
Crucially, a positive statement does not have to be true. "The minimum wage has no effect on employment" is positive because it is testable, even if the evidence ends up refuting it.
Normative statements
A normative statement is a value judgement about what ought to be. It cannot be settled by evidence alone, because it rests on opinions about what is good, fair or desirable. Signal words include should, ought, fair, too much, and better.
- "The government should reduce income inequality."
- "Healthcare ought to be free."
Why value judgements enter economics
Economic analysis is mostly positive: it traces causes and effects, such as how a tax changes price and quantity. But almost every real decision also rests on normative judgements:
- Whose welfare counts. A policy that helps consumers may hurt producers; deciding it is worthwhile is a value judgement.
- What is fair. Trade-offs between efficiency and equity cannot be resolved by facts alone.
- What weight to give the future. How much present consumption to sacrifice for future generations is a normative choice.
This is why economists can agree on the positive analysis of a policy yet disagree on whether it should be adopted.
Examples in context
Example 1. Evaluating a Singapore policy. When the government raised the Goods and Services Tax, the positive analysis (it raises revenue and slightly reduces consumption) can be settled with data. Whether the rise was fair, given its impact on lower-income households, is normative and depends on how one weighs equity against revenue needs. A strong answer keeps the two strands distinct.
Example 2. Why exam evaluation rewards this skill. High-mark essay and case-study parts ask you to evaluate, which means combining positive analysis (what the effects are) with a clearly justified normative judgement (which effect matters most and why). Spotting the value judgement and defending it is exactly the higher-order thinking the markers reward.
Try this
Q1. Classify "the inflation rate was 3 percent last year" and explain. [2 marks]
- Cue. Positive: it is a factual claim about what happened that can be checked against the data.
Q2. Explain why "the government should reduce inequality" is a normative statement. [2 marks]
- Cue. The word should signals a value judgement about what ought to be; whether reducing inequality is desirable cannot be settled by evidence alone.
Q3. Explain why policy decisions cannot be made by positive analysis alone. [3 marks]
- Cue. Positive analysis predicts the effects of each option, but choosing between options requires judgements about whose welfare counts and what is fair, which are normative and not settled by facts.

Original8 marksDistinguish between positive and normative statements in economics, and explain why the distinction is important when evaluating policy.Show worked answer →
An 8 mark question rewards precise definitions, clear examples, and the link to evaluation.
- Positive statements
- A positive statement is objective and testable against evidence: it describes what is, was or will be. Example: a rise in the carbon tax raises the price of petrol.
- Normative statements
- A normative statement is a value judgement about what ought to be, often signalled by words like should, fair or too high. Example: the government should raise the carbon tax.
- Why it matters for policy
- Economic analysis can establish the positive effects of a policy, but the decision to adopt it rests on normative judgements about whose welfare matters and what is fair. Recognising which is which lets a candidate separate the analysis (positive) from the recommendation (normative) and evaluate each on its own terms.
Markers reward the testable-versus-value-judgement contrast, correct examples of each, and the point that policy choices combine positive analysis with normative judgement.
Original6 marksClassify each of the following as positive or normative, with reasons: (a) unemployment rose last quarter; (b) the government should cut income tax; (c) a minimum wage reduces employment of low-skilled workers.Show worked answer →
A 6 mark classification question rewards a correct label and a one-line justification for each.
- (a) Positive
- It is a factual claim about what happened that can be checked against the data.
- (b) Normative
- The word should signals a value judgement about what ought to be done; it cannot be proved true or false by evidence alone.
- (c) Positive
- It is a testable claim about cause and effect; whether it is actually true is an empirical question, but it is still positive because it can in principle be tested.
Markers reward correct classifications and the reasoning that a positive statement is testable while a normative one rests on values, noting that a positive statement need not be true to be positive.
