IB Economics Paper 1 Essay Technique: Common Questions Answered
Answered by RevisionPrep's IB Educators
Paper 1 rewards structure, not just knowledge — most lost marks come from weak diagrams and evaluation, not missing content. I've marked hundreds of these essays. Here's exactly where students throw marks away and how to stop it.
Difficulty & Grades
Why do students lose marks on Paper 1 essay technique in IB Economics?
Most marks vanish through weak diagrams (missing labels, wrong axes), thin evaluation (just "it depends" with no reasoning) and answering the theory instead of the actual command term. Examiners reward application to the stem and a genuine judgement — not restated definitions.
According to the IB Economics guide (first exams 2025), Paper 1 uses the same markbands across SL and HL, assessed against knowledge/understanding, application/analysis, synthesis/evaluation and use of terminology.
Quick tip: before you write a word, underline the command term and the specific context (country, market, policy) in the question — that's your evaluation anchor.
How many marks is Paper 1 worth and how is it structured?
Paper 1 is a two-part essay from a choice of two, each worth 25 marks — 10 for part (a) and 15 for part (b) at both SL and HL. It's 1.5 hours at SL and 2.25 hours at HL, both papers weighted 30% of the final grade.
| Level | Time | Weighting |
|---|---|---|
| SL | 1h15 | 30% |
| HL | 1h45 | 30% |
Note: the extra HL time reflects the additional HL extension content examinable in part (b), not extra questions.
Is Paper 1 harder than Paper 2 or Paper 3?
Paper 1 is generally considered harder because there's nowhere to hide — no data or stimulus scaffolding your answer like in Paper 2, and no calculations to anchor marks like in Paper 3 HL. It rewards pure essay control: structure, diagrams, evaluation.
Students who are strong on content but weak on exam technique often score lower on Paper 1 than on Paper 2, where the stimulus material effectively hands you application marks.
How to Improve Technique & Get a 7
How do I structure a Paper 1 essay to get top marks?
Use a clear four-part shape for each sub-question: define key terms, build the diagram, explain the mechanism using the diagram, then evaluate. Part (a) needs the first three; part (b) adds sustained evaluation — a real judgement, not a summary.
- Define the 2-3 key terms in the question.
- Draw and correctly label the diagram (axes, curves, equilibrium points, shifts).
- Explain the chain of reasoning the diagram shows, step by step.
- Evaluate: use criteria like time frame, elasticity, magnitude, or stakeholder perspective — don't just say "however, it depends."
Common mistake: writing the evaluation as a vague conclusion paragraph instead of weaving a real counter-argument through part (b).
How do I draw and explain economics diagrams properly?
Label both axes correctly (price/quantity or the specific variable), title the diagram, show initial and new equilibrium clearly, and reference it explicitly in your prose — "as shown by the shift from S1 to S2." A diagram that isn't referred to in the text earns almost nothing.
Worked example: for a negative production externality question, draw MPC, MSC, MPB=MSB, mark the welfare loss triangle between Qm and Qopt, and state the welfare loss in words — "the shaded triangle represents the welfare loss to society at the market quantity."
Quick tip: always draw diagrams in pencil first if you're unsure, then ink over — a smudged, unlabelled diagram loses marks even if the economics is right.
What does good evaluation actually look like in Paper 1?
Good evaluation weighs the argument against a real criterion — time frame, elasticity, size of the effect, or whose perspective (consumer vs producer vs government) — rather than just listing a counterpoint. Examiners want a reasoned judgement in the final paragraph, not a shrug.
Example evaluative sentence: "In the short run, a subsidy may not raise output much if supply is price inelastic, but over time, as firms invest the subsidy into capacity, the effect on quantity supplied grows substantially."
That's evaluation because it names a specific mechanism (elasticity, time) — not just "it depends on the country."
How do I manage my time in the Paper 1 exam?
Split roughly 45 minutes per question at HL (35 at SL), spending about 12-15 minutes on part (a) and the rest on part (b) since it's worth more. Spend two minutes planning before you write — a rushed diagram costs more than a rushed sentence.
- Read both questions fully before choosing (2 min).
- Plan diagram + evaluation criteria for your chosen question (3 min).
- Write part (a): definitions, diagram, explanation (12-15 min).
- Write part (b): diagram, explanation, sustained evaluation (remaining time).
Common mistake: spending 20 minutes perfecting part (a) and rushing the evaluation in part (b), where most of the marks actually sit.
What command terms come up most in Paper 1 and what do they require?
"Explain" needs a mechanism with a diagram; "evaluate" needs a judgement with reasoned criteria; "discuss" needs balanced points before a conclusion. Misreading "evaluate" as "explain" is one of the most common ways strong students still miss the top markband.
| Command term | What examiners want |
|---|---|
| Explain | Cause-effect chain, usually with a diagram |
| Evaluate | Judgement using named criteria |
| Discuss | Multiple viewpoints, then a stance |
These definitions follow the command terms glossary in the IB Economics guide.
Exam & Syllabus
Do I have to answer on all four syllabus units in Paper 1?
No — Paper 1 draws questions from a mix of the four syllabus units (microeconomics, macroeconomics, the global economy, and their overlaps), but you only answer one full two-part question from a choice of two on the exam paper itself.
According to the current IB Economics guide (first exams 2025), the four units are: Introduction to Economics, Microeconomics, Macroeconomics, and the Global Economy — Paper 1 questions typically sit within one unit but can draw connections across others for higher marks.
What's the difference between Paper 1 at SL and HL?
The exam format is identical — same two-part essay structure and same 25-mark total — but HL students get an extra 30 minutes and must be ready to apply HL-extension content (like the Keynesian multiplier or exchange rate calculations) if it appears in part (b).
| Feature | SL | HL |
|---|---|---|
| Time | 1h15 | 1h45 |
| Marks | 25 | 25 |
| HL-only content examinable | No | Yes |
The markbands themselves (knowledge, application, synthesis/evaluation, terminology) are shared — HL isn't marked more harshly, it just covers more ground.
How are Paper 1 essays actually marked?
Examiners use four assessment objectives per sub-question: knowledge and understanding, application and analysis, synthesis and evaluation, and use of terminology — with evaluation weighted most heavily in part (b), where the extra five marks over part (a) mostly live.
Quick tip: a well-labelled diagram alone can secure application marks even if your written explanation is a little thin — but it can't replace the evaluation marks, which only come from explicit reasoned judgement.
Comparisons & Choices
Is Economics HL worth it compared to SL for university?
HL Economics is worth it if your child is aiming at economics, business, PPE or finance degrees, since several competitive universities specify HL for these courses. SL suits students who want solid economic literacy without the extra HL-only content load in macro and Paper 3.
The core difference isn't difficulty of ideas but volume — HL adds topics like the Keynesian multiplier, real vs nominal GDP calculations, and a third exam paper (Paper 3, HL only, data-response style with quantitative skills).
How much does exam practice and revision support cost for IB Economics?
Costs range widely — free past papers from school, to paid revision guides (roughly USD 20-40), to full topical worksheet and mock paper platforms. On RevisionPrep, students can access Economics Revision Notes, Topical Worksheets and Mock Papers built specifically around the current syllabus and markbands, without paying for one-to-one coaching.
