Economics Extended Essay: The Complete IB Guide
By Michael Thompson · Education Specialist; 10 years teaching the IB at Bromsgrove School · Published 4 September 2026 · Updated 4 October 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. From May 2027 the IB assesses it on five criteria worth a combined 30 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.
Key Takeaways
- Five criteria, 30 marks total: Criterion A (Framework for the essay, 6), B (Knowledge and understanding, 6), C (Analysis and line of argument, 6), D (Discussion and evaluation, 8) and E (Reflection, 4) - discussion and evaluation is the heaviest criterion, and there is no separate presentation criterion.
- Narrow your research question relentlessly: A strong economics RQ names a specific market, firm, region, or policy - not an entire economy or sector - and is answerable with data you can actually obtain.
- Data is the essay's backbone: Examiners expect you to apply a model to real evidence; describing a model without connecting it to data is one of the most common reasons essays score poorly on criteria C and D.
- Choose recent, checkable evidence: A question about a recent policy or market gives you data you can still find and verify; a question about an event that has not happened yet cannot be answered with evidence at all.
- The reflective statement is worth 4 marks and is read by the examiner: Criterion E is marked only from one reflective statement of no more than 500 words on the Reflection and progress form (RPF), written at the end of the process - treat it as part of the essay, not an afterthought.
- Description is not analysis: Explaining what a minimum wage policy does is description; using a labour-market supply-and-demand diagram with your own data to evaluate its effect on employment in a named location is analysis.

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 guidance, economics sits within the individuals and societies group, alongside business management, geography, global politics, history and psychology. The IB's Extended essay guide (first assessment 2027) gives its subject-specific advice at group level, so read the individuals and societies section rather than looking for a separate economics chapter.
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, which replaces the World Studies EE in the new extended essay, launched in February 2025 and first assessed in May 2027. It is marked on the same five criteria as a subject-focused essay.
2. The Five Assessment Criteria Explained for Economics
The IB's Extended essay guide (first assessment 2027) gives every essay, in every subject, a maximum of 30 marks across five criteria. Knowing the weight of each criterion changes how you allocate your effort.
| Criterion | Focus | Max marks |
|---|---|---|
| A | Framework for the essay | 6 |
| B | Knowledge and understanding | 6 |
| C | Analysis and line of argument | 6 |
| D | Discussion and evaluation | 8 |
| E | Reflection | 4 |
| Total | 30 |
Criterion A: Framework for the essay (6 marks). Three strands: research question, research methods and structure. Examiners check whether your question is relevant, clear and focused, whether your methods suit it and are explained and applied, and whether your structure supports communication of the research. A survey analysing consumer price sensitivity is appropriate; a vague "what causes inflation" question is not. The method, whether primary survey data, secondary data, or a case-study approach, must be justified, not just stated - and the guide warns that if there are not enough sources of suitable quality for your methods, you should change the question.
Criterion B: Knowledge and understanding (6 marks). This rewards relevant research materials, accurate and consistent terminology, and relevant concepts used effectively. The guide's own example of individuals and societies terminology is "supply and demand" in economics. Examiners are not impressed by a tour of every model you have encountered. Precision matters more than breadth.
Criterion C: Analysis and line of argument (6 marks). This rewards analysis that consistently produces relevant findings, and a clear, sustained line of argument linking your research question, your findings and your conclusion. An essay that is descriptive rather than analytical sits in the bottom band, however accurate it is.
Criterion D: Discussion and evaluation (8 marks). The heaviest criterion. It rewards a balanced discussion of the significance of your findings, fully supported by evidence, and an evaluation of the effectiveness of your essay - the strengths and limitations of your data, sources and models, explained rather than just listed. The guide wants evaluation integrated throughout, not saved for one section.
Criterion E: Reflection (4 marks). Assessed only from your reflective statement (no more than 500 words) on the Reflection and progress form (RPF). The essay itself cannot improve this score.
Presentation is no longer a separate criterion: labelled diagrams, headings and consistent referencing now count through criterion A's structure strand.
To see what examiners reward, read the IB's published Example B, the Moscow Metro pricing essay, with its examiner commentary. It was marked under the pre-2027 criteria, so its mark does not translate to the 30-mark scale, but the commentary on its data use and its evaluation of the model still applies.
November 2026 candidates only: the final session on the old model marks the essay out of 34 - A Focus and method (6), B Knowledge and understanding (6), C Critical thinking (12), D Presentation (4) and E Engagement (6) - with E taken from the three-entry Reflections on planning and progress form (RPPF, 500 words in total).
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 2027 guide asks for
The IB's Extended essay guide (first assessment 2027) sets two practical boundaries that bite hard in economics:
- Answerable with evidence. The question has to support a line of argument built on research findings. A question about an event that has not happened yet - the effect of a future tournament on a city's economy, say - cannot be answered with data, so it fails before you start.
- Workable scope. The guide asks you to imagine answering the question comfortably within 4,000 words, and to change the question if there are not enough sources of suitable quality for your methods.
The previous guide also told economics students to keep topics to no more than about five years old. That rule does not appear in the 2027 guidance, whose own example question on mobile banking looks back to 2010, but recent topics are still usually easier because the data is available and current.
Topics can be drawn from any part of the 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
A question about a whole economy is almost impossible to analyse rigorously in 4,000 words. "How does interest rate policy affect the UK economy?" is too broad. Narrow it to one part of the economy, one mechanism and one place. The 2027 guide's own economics examples follow that pattern: one tests the neoclassical argument about minimum wages and unemployment against recent research and data, and the other asks how access to mobile banking has contributed to economic development in a single town or village. The previous guide's examples were just as narrow:
- Minimum wage effects on fast food unemployment in Graz, Austria
- The fall of the US dollar's exchange rate and its effect on tourism in Carmel, California
- Water privatisation effects on farming in a specific region of Zambia
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)
| Area | Weak version | Improved version |
|---|---|---|
| Inflation | How 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 policy | How 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
| Section | Purpose | Suggested words |
|---|---|---|
| Introduction | State the RQ, define scope, explain significance | ~400 |
| Theoretical framework | Identify and explain the model(s) you will apply | ~500 |
| Data and evidence | Present and contextualise your primary/secondary data | ~700 |
| Analysis | Apply the model directly to your data | ~1,000 |
| Evaluation | Assess findings, limitations, and alternative views | ~700 |
| Conclusion | Answer the RQ, note unresolved questions | ~300 |
| References/bibliography | Not counted toward the 4,000-word limit | - |
Analysis and evaluation deliberately get the largest share between them. Together they serve criteria C and D, which carry 14 of the 30 marks - and because the guide wants evaluation integrated throughout, your analysis section should already be weighing the evidence, not just presenting it.
Structure: the easy marks students drop
Structure is assessed through criterion A's structure strand, and much of it is 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 RPF sits outside the word count
Your reflective statement (no more than 500 words) goes on the Reflection and progress form, which does not count toward the 4,000-word limit. 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. Narrow it to one sector, one location and one time period, as in the examples in section 3.
Data quality affects criteria A, B and D. Criterion A asks for enough sources of suitable quality for your methods, B's knowledge strand rewards comprehensive, relevant research materials, and D asks you to weigh their strengths and limitations. 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, undermines the balanced discussion that criterion D rewards - and D is the heaviest criterion, at 8 of the 30 marks.
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 RPF, Reflection Sessions, and Criterion E
Criterion E (Reflection) is worth 4 marks and is assessed only from your reflective statement on the Reflection and progress form (RPF). The examiner reads it alongside the essay itself, not as an afterthought.
You have three mandatory reflection sessions with your supervisor, and attendance at each is recorded on the RPF:
- First reflection session - a dialogue based on your initial explorations: possible topics, questions emerging from your reading, and suitable methods.
- Interim reflection session - once your research is under way: progress, problems you have hit, and whether the research question needs amending.
- Final reflection session (viva voce) - after the essay is complete: what you learned, and the authenticity of your ideas.
The reflective statement itself is one piece of no more than 500 words, written at the end of the process. The top band needs reflection that is consistently evaluative, uses specific examples, and shows your growth and how you would transfer what you learned to other contexts.
What strong reflection actually says (illustrative): "When I could not find reliable older ridership data, I switched to fare elasticity estimates from academic papers and narrowed my research question. Checking that a dataset exists before committing to a question is a habit I now use in every project." 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 is one of the main sources the guide suggests for your reflective statement.
The non-obvious gotcha: because the statement is written at the end, it can only be specific if you kept a record along the way. The guide recommends a researcher's reflection space - a notebook or digital log - for exactly this. Write notes within a day or two of each 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 reflection form and a full examiner commentary. Both were marked under the pre-2027 criteria, so read them for what the examiner praises and criticises rather than for the marks. Read the examiner commentary first - it explains precisely where marks were awarded and dropped, which is more instructive than the essay itself.
Example B is a strong essay. 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:
- Focused RQ tied to one named policy or market
- One or two well-chosen models, applied to real cited data
- Genuine evaluation, including model limitations
- Conclusion that returns to the RQ
Weak-essay pattern (common failure mode):
- Broad RQ covering an entire industry or country
- Multiple models introduced but never applied
- Data presented in a table with no analytical commentary
- Conclusion that restates the introduction word-for-word
One non-obvious gotcha: Example B still dropped marks despite strong data use - the examiner noted that evaluation of the externalities model's assumptions was present but underdeveloped. Under the 2027 criteria that is criterion D territory: describing a model's limitations is not the same as explaining their implications for your conclusion.
Access to these examples requires your school's IB account, 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 is reading the examiner commentary on the IB's published Example B. It was marked under the pre-2027 criteria, but its comments on data use and on evaluating the model map directly onto criteria C and D, which carry 14 of the 30 marks. That 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?
From May 2027 there are five criteria: Criterion A Framework for the essay (6 marks), Criterion B Knowledge and understanding (6 marks), Criterion C Analysis and line of argument (6 marks), Criterion D Discussion and evaluation (8 marks) and Criterion E Reflection (4 marks), totalling 30 marks; E is marked only from the reflective statement on the RPF.
How many words is the economics extended essay?
No more than 4,000 words, and examiners do not read beyond that; the reflective statement (up to 500 words) goes on the separate Reflection and progress form (RPF) and does not count toward the essay's 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 the student's reflection form and an examiner commentary, on its Programme Resource Centre - accessible through your school's IB account; both were marked under the pre-2027 criteria, so learn from the commentary rather than the marks.
