Economics Extended Essay: The Complete IB Guide

By Michael Thompson · Former IB Diploma Programme coordinator; 10 years at Bromsgrove School · Published 4 September 2026

An economics extended essay asks you to do something most school assignments don't: collect real data, apply an economic model to it, and argue a position - all within 4,000 words. The IB assesses it on five criteria worth a combined 34 marks, and the spread of those marks matters as much as the total. Most essays that fall short do so not because the economics is wrong, but because the research question is too broad, the data is thin, or the writing describes a policy rather than analysing it. This guide covers every criterion, shows you what a strong research question looks like, and explains where marks are most commonly lost - so you can avoid the same traps.

1. What an Economics Extended Essay Actually Is

An economics extended essay is a 4,000-word independently researched paper that forms a mandatory part of the IB Diploma Programme core, assessed externally by the IB. It is not a class assignment or internal project. The IB examines it blind, which means the quality of your argument and evidence has to stand entirely on its own.

For subject classification, economics sits within the "Individuals and societies" group, alongside history, geography, and psychology. That grouping matters when you register your essay subject with your coordinator.

The non-obvious requirement is this: economics must be the method, not just the setting. An essay investigating a local supermarket's pricing is not an economics EE unless it applies specific economic models, such as price elasticity, market structure theory, or game theory, as the analytical tools. Background context written in economics language is not enough.

If you want to combine economics with another DP subject, the correct route is the interdisciplinary pathway. The World Studies EE has been absorbed into this new pathway, which launches in February 2025 with first assessment in May 2027.

Students assessed before that cohort follow the current five-criterion, 34-mark framework described throughout this guide.

2. The Five Assessment Criteria Explained for Economics

!IB economics extended essay mark allocation across five criteria showing Criterion C worth 12 of 34 marks.webp5911

The IB's extended essay assessment criteria give every economics essay a maximum of 34 marks across five areas. Knowing the weight of each criterion changes how you allocate your effort.

CriterionFocusMax marks
AFocus and method6
BKnowledge and understanding6
CCritical thinking12
DPresentation4
EEngagement6

Criterion A: Focus and method (6 marks). Examiners check whether your research question is genuinely focused and whether your chosen methodology fits an economics investigation. A survey analysing consumer price sensitivity is appropriate; a vague "what causes inflation" question is not. The methodology choice, whether primary survey data, secondary econometric data, or a case-study approach, must be justified, not just stated.

Criterion B: Knowledge and understanding (6 marks). This rewards accurate use of economic terminology, theories, and models that are relevant to your specific research question. Examiners are not impressed by a tour of every model you have encountered. Precision matters more than breadth.

Criterion C: Critical thinking (12 marks). This is the criterion that determines grade boundaries more than any other, worth more than A and B combined. It rewards genuine argument, evaluation of evidence, and honest recognition of limitations. Summary and description score poorly here regardless of how accurate they are.

Criterion D: Presentation (4 marks). Correct formatting, a proper bibliography, page numbering, and labelled tables and figures. These are largely free marks if you follow the IB's rules.

Criterion E: Engagement (6 marks). Assessed entirely through the RPPF, a separate 500-word document with three reflection entries completed at set points. The essay itself cannot improve this score.

To see what a realistic mark distribution looks like, the IB's published Example B, the Moscow Metro pricing essay, scored 5+5+10+4+4, totalling 28 out of 34. Notice that it dropped two marks on Critical thinking and two on Engagement, the most common pressure points, while achieving full marks on Presentation, the criterion most students neglect.

3. Choosing IB Economics Extended Essay Topics That Work

The biggest mistake students make when picking an economics extended essay topic is choosing something that feels important but cannot be tested. A question you cannot answer with real, recent data is not a research question - it is a discussion prompt.

What the IB requires

The IB's Economics EE guidance sets two hard boundaries:

Topics can be drawn from any section of the current Economics syllabus, but are not restricted to it. The constraint is methodological: the investigation must use economic theories, models, and tools as its basis.

The macroeconomics trap

IB guidance is explicit that macroeconomics topics must be narrowed to a particular part of the economy, not the economy as a whole. "How does interest rate policy affect the UK economy?" is too broad to analyse rigorously in 4,000 words. The IB's own focused examples show what the right level of specificity looks like:

Notice that each example names a sector, a mechanism, and a place. That combination is what makes the question answerable.

Weak vs. improved topics (written for this guide)

AreaWeak versionImproved version
InflationHow does inflation affect consumers?How has the ONS CPI measure for food and non-alcoholic beverages in London changed the purchasing decisions of low-income households between 2021 and 2024?
Trade policyHow do tariffs affect trade?What has been the effect of the US Section 232 steel tariff (2018, maintained post-2022) on output at small US steel producers in the Midwest?

The improved versions are harder to write - and that is precisely why they score higher. A narrower question forces you to find specific data, apply a specific model, and reach a specific conclusion.

The dataset test

Before finalising any economics extended essay question, ask yourself: can I name the exact dataset I will use? If the answer is vague ("some government statistics" or "news articles"), the question is still too broad. ONS, the Federal Reserve FRED database, the World Bank Open Data portal, and national statistics offices all publish the kind of sector-level, time-series data that makes a focused question answerable. If you cannot identify a specific dataset before approval, narrow the question further until you can.

4. IB Economics Extended Essay Structure: How to Organise 4,000 Words

The IB sets a hard 4,000-word cap on the economics extended essay. Words beyond that limit are not read by the examiner. That is not a suggestion to write less - it is a structural constraint that forces you to cut anything that does not directly serve your research question.

The non-obvious trap: students routinely burn 400-500 words on country or industry background that never connects to the model or the argument. If a paragraph does not feed the RQ, it does not belong.

Standard structure and word budget

SectionPurposeSuggested words
IntroductionState the RQ, define scope, explain significance~400
Theoretical frameworkIdentify and explain the model(s) you will apply~500
Data and evidencePresent and contextualise your primary/secondary data~700
AnalysisApply the model directly to your data~1,000
EvaluationAssess findings, limitations, and alternative views~700
ConclusionAnswer the RQ, note unresolved questions~300
References/bibliographyNot counted toward the 4,000-word limit-

The analysis section deliberately gets the largest share. That reflects the weighting of Criterion C (critical thinking), which examiners treat as the core of the essay.

Criterion D: the free marks students drop

Criterion D covers presentation and is largely mechanical: a title page, a contents page, page numbers, labelled figures and tables, consistent in-text citation, and a bibliography. These cost almost no writing time. Students still drop marks here because they label a diagram "Figure 1" in the text but call it "Graph A" in the caption, or because they switch citation styles mid-essay.

The RPPF sits outside the word count

The Reflections on Planning and Progress Form (500 words across three reflection points) is submitted separately. It does not count toward the 4,000-word limit, and nothing written in it replaces content that belongs in the essay itself.

5. Why Economics Essays Lose Marks: Data, Sources, and Scope

The most common failure mode is not poor writing. It is collecting a model, such as price elasticity or perfect competition, and then describing it in the abstract without anchoring it to real data from the chosen context. An examiner reading a section on minimum wage theory wants to see a labour-market diagram drawn against your actual data, and then an evaluation of whether the predicted employment effect appeared in the evidence. Describing what the model says is not analysis.

Scope is where essays quietly collapse. A research question like "the impact of inflation on the UK economy" cannot be answered in 4,000 words. The IB EE subject guidance is explicit: macroeconomics topics must be narrowed to a particular part of the economy. The same guidance gives worked examples of focused questions, including minimum wage effects on fast food employment in Graz, Austria, and exchange-rate effects on tourism in Carmel, California. One sector, one location, one time period.

Data quality directly affects Criterion B. Secondary data from national statistics offices, central bank reports, World Bank datasets, or peer-reviewed journals is appropriate for an academic investigation. Wikipedia and general news articles are not sufficient as standalone sources, and examiners check. A counter-intuitive gotcha: a newspaper article can be a legitimate primary source if the essay is investigating media framing, but not if it is being used as evidence of an economic outcome.

Watch for confirmation bias. Using data only to support your expected conclusion, without acknowledging counter-evidence, is penalised under Criterion C, which carries the highest mark weighting at 12 of the 34 available points, as shown in the IB sample essay scoring.

If your survey data and official statistics point in different directions, do not smooth over the gap. That discrepancy is an analytical point in itself, and treating it as one will earn more marks than pretending the conflict does not exist.

6. The RPPF, Reflection Sessions, and Criterion E

Criterion E (Engagement) is worth 6 marks and is assessed entirely through the Reflections on Planning and Progress Form (RPPF). The examiner reads it alongside the essay itself, not as an afterthought.

The RPPF has three entries:

The total word limit across all three entries is 500 words. Concise, specific entries score better than vague ones. The IB sample essay on Moscow Metro's pricing strategy received 4 out of 6 for Criterion E, a useful benchmark for what mid-range engagement looks like in practice.

What strong reflections actually say: "I could not access reliable pre-2015 Moscow Metro ridership data, so I shifted to fare elasticity estimates from academic papers and adjusted my research question accordingly." That is useful. "I enjoyed researching this topic" is not.

The viva voce is a short conversation with your supervisor at the end of the process. It does not alter your essay mark directly, but it informs your final reflection and shapes the supervisor's report that accompanies your submission.

The non-obvious gotcha: examiners are experienced enough to spot retrospective RPPF entries, where a student has clearly written all three reflections in one sitting at the end. The language becomes suspiciously uniform and the "problems" described are too neatly resolved. Write each entry within a day or two of the relevant session, while the specific details are still fresh.

7. Economics Extended Essay Examples: What a High-Scoring Essay Does Differently

The IB publishes two assessed economics extended essay examples on its Programme Resource Centre, labeled Example A and Example B. Each comes with the student's RPPF and a full examiner commentary. **Read the examiner commentary first** - it explains precisely where marks were awarded and dropped, which is more instructive than the essay itself.

Example B scored 28 out of 34. Its research question - "How effective has state-owned Moscow Metro's pricing strategy been in reducing the negative externalities of car use in the city?" - illustrates several features that distinguish a high-scoring economics extended essay. The RQ names a specific city, a specific policy instrument, and a specific economic concept. Metro pricing and ridership data are then applied to an externalities model rather than just quoted. The conclusion answers the RQ directly.

High-scoring pattern:

Weak-essay pattern (common failure mode):

One non-obvious gotcha: Example B lost marks on Criterion C (Critical thinking, 10/12) despite strong data use - the examiner noted that evaluation of the externalities model's assumptions was present but underdeveloped. Describing a model's limitations is not the same as evaluating their implications for your conclusion.

Access to these examples requires your school's IB account. Supervisors cannot share them outside school, so ask your coordinator to walk you through both examples in a supervised session.

8. What to Do Next

This week, draft three candidate research questions. Before your first supervisor meeting, apply one test to each: can you name the specific dataset you would use to answer it? If you cannot, the question is still too broad. Bring all three to that first meeting and let your supervisor help you cut to one.

One of the most efficient preparation steps available is reading the examiner commentary on the IB's published Example B, which scored 28 out of 34. The commentary explains precisely why Criterion C (Critical thinking) lost two marks while Criterion D (Presentation) was awarded full marks. That gap is far more instructive than any checklist.

Read the examiner notes before you finalise your question. Then contact your supervisor.

FAQ

How do I write an economics extended essay?

Start with a narrow, answerable research question tied to a specific market, region, or policy; identify your data source before finalising the question; then structure the essay around applying one or two economic models to that data, evaluating what the evidence shows, and acknowledging the limits of your analysis.

What is an economics extended essay?

An economics extended essay is a 4,000-word independent research paper required for the IB Diploma, in which students investigate a focused economic question by applying economic theories and models to real data and evidence.

Are economics extended essays a good choice?

Economics EEs suit students who can access usable data on a specific question - the subject rewards analytical rigour over literary skill, which some students find more straightforward, but the data requirement makes topic selection more critical than in humanities subjects.

What are the economics extended essay assessment criteria?

The current framework has five criteria: Criterion A Focus and method (6 marks), Criterion B Knowledge and understanding (6 marks), Criterion C Critical thinking (12 marks), Criterion D Presentation (4 marks), and Criterion E Engagement (6 marks), totalling 34 marks.

How many words is the economics extended essay?

The hard limit is 4,000 words; the RPPF (Reflections on Planning and Progress Form) is a separate 500-word document submitted alongside the essay and does not count toward the word limit.

Where can I find IB economics extended essay examples?

The IB publishes two assessed economics examples (Example A and Example B), each with an RPPF and examiner commentary, on its Programme Resource Centre - accessible through your school's IB account; your supervisor can show you how to find them.
