IB Economics HL Study Guide & Review

Integrate deeper economic theory, quantitative evidence, accurate diagrams and real-world analysis, then build conditional policy recommendations for the current IB Economics HL course and Paper 3.

How to study IB Economics HL

Integrate deeper theory, quantitative work, diagrams, evidence and policy judgment across the current IB Economics HL syllabus and Paper 3.

IB Economics HL is not SL with four extra microeconomics headings. Use the syllabus map to connect additional theory and quantitative depth across all four units. For each problem, construct the model and diagram, calculate where required, interpret the result economically, apply real evidence and evaluate policy conditions. A correct calculation is only an intermediate step; the final response must explain what changes for households, firms, government or external stakeholders.

Use Concept to compare models, Mastery to retrieve equations, diagrams and examples, and the Question Bank for mixed data and policy work. Classify losses as theory, diagram, calculation, interpretation, data use, application or policy judgment. Repair the earliest failed decision before attempting a harder Paper 3 set.

Practise HL theory and policy together

Combine additional theory, calculations, diagrams and real evidence, then convert the result into a conditional policy judgment rather than stopping at accuracy.

  1. HL microeconomics and market power

    Maximizing behaviour, asymmetric information, market power and equity

    Compare model assumptions before drawing the diagram or calculating. Trace welfare and distributional effects, apply market evidence and judge intervention using effectiveness, unintended consequences, stakeholder impacts and information limits.

    Practise HL microeconomics

  2. HL macroeconomic mechanisms

    Multiplier, monetary theory, policy transmission and competing schools

    Show quantitative steps where required, interpret the magnitude, then connect the mechanism to output, prices, employment and distribution. Evaluate policy lags, expectations, spare capacity and interaction with other measures.

    Practise HL macroeconomics

  3. HL global and development analysis

    Comparative advantage, exchange-rate systems, balance of payments and development

    Move between calculation, diagram and specific country evidence. Explain how the result changes incentives, welfare and distribution, then compare policies through feasibility, equity, sustainability and important external constraints.

    Practise HL global economics

  4. Paper 2 shared-content data response

    Seven-part source analysis excluding HL extension material

    Keep Paper 2 practice inside shared content. Extract and reuse source evidence, construct diagrams accurately, answer each command term directly and reserve broader HL knowledge for relevant explanation rather than extension-only theory.

    Practise HL Paper 2

  5. Paper 3 quantitative policy work

    Two compulsory questions, calculations and policy recommendations

    Show formula, workings, units and rounding, then interpret every result. Connect quantitative evidence to theory and diagrams, compare policy options and recommend one with explicit conditions, trade-offs and limitations.

    Practise Paper 3

Where to start

Start from one precise HL theory or quantitative gap, or use mixed data to locate the first failed analytical decision.

Choose your starting point

  1. I know the weak area

    Open the exact shared or HL Topic and identify its model, equation, diagram and linked policy question.

    Browse the HL syllabus

  2. The failure is unclear

    Attempt a mixed set and stop at the earliest repeated breakdown in setup, interpretation or policy evaluation.

    Open mixed HL questions

Choose the right starting point

  1. Model and quantify

    State assumptions, build the diagram, show calculations and explain what the numerical result means economically.

    Review a Concept

  2. Connect evidence and policy

    Retrieve a relevant example, identify stakeholders and trace the policy mechanism across short- and long-run effects.

    Check Mastery

  3. Recommend and stress-test

    Compare policies, test constraints and distributional effects, then repair the first unsupported step after marking.

IB Economics HL assessment format

External assessment contributes 80% and the three-commentary portfolio contributes 20%. HL preparation must integrate quantitative interpretation with policy recommendation while keeping Paper 2 inside shared content.

Paper / componentQuestionsTime% of grade
Paper 125 marksAnswer one of three extended-response questions; each choice contains a 10-mark part and a 15-mark part across the four units.How to prepare: Practise sustained model-based argument with accurate diagrams, specific real-world evidence, counterargument and a qualified judgment.1 hour 15 minutes20%
Paper 240 marksAnswer one of two data-response questions; the chosen question has seven parts across shared content and excludes HL extension material.How to prepare: Annotate and reuse supplied evidence throughout calculations, diagrams, explanations and evaluation instead of reproducing a memorised essay.1 hour 45 minutes30%
Paper 360 marksTwo compulsory 30-mark policy questions; each combines a 20-mark quantitative or structured part with a 10-mark policy recommendation.How to prepare: Show quantitative working and interpretation, then compare policies and recommend with explicit conditions, distributional effects and implementation constraints.1 hour 45 minutes30%
Internal assessment portfolio45 marksThree commentaries of no more than 800 words each, using different non-introductory units, news sources and key concepts.How to prepare: Select current articles with a clear economic issue, apply one focused model and make evaluation answer the evidence rather than summarizing the news.20 recommended course hours20%

IB Economics HL questions

HL adds theoretical and quantitative depth across the four units, including four whole additional microeconomics Topics, and includes Paper 3. Revision should integrate calculation, diagram, interpretation, evidence and policy judgment rather than treating HL as extra definitions.

Practise the full chain: write formulas and workings, check units and rounding, interpret the result economically, connect it to theory and diagrams, then compare policies and recommend one with conditions, stakeholder effects and limitations.

No. Current examiner instructions state that Paper 2 excludes HL extension material. Practise the shared content through supplied data, diagrams and evaluation, while reserving extension-only theory for components where it is relevant.

The task is the same three-commentary portfolio at both levels, including the 800-word limit per commentary. The assessment weighting differs: the portfolio contributes 30% at SL and 20% at HL.
