The Complete Guide to IB Economics and the IA
I. Introduction to IB Economics
A. What is IB Economics?
The International Baccalaureate (IB) Economics course is a comprehensive program designed to provide students with a thorough understanding of economic principles, theories, and their applications in the real world. This course, available at both Standard Level (SL) and Higher Level (HL), is an integral component of the IB Diploma Programme.
IB Economics encompasses four key areas of study:
- Introduction to economics
- Microeconomics
- Macroeconomics
- The global economy (international trade and development)
The curriculum is structured to cultivate analytical and evaluative skills, enabling students to interpret complex economic scenarios and formulate well-reasoned judgments. A distinguishing feature of the course is its emphasis on applying economic theories to contemporary global issues, thereby bridging the gap between theoretical knowledge and practical application.
B. Importance of Economics in the Modern World
The significance of economics in the modern world cannot be overstated. In an era characterized by global interconnectedness, economic literacy is crucial for navigating personal, professional, and societal challenges. The study of economics provides valuable insights into:
- Market dynamics
- Government policy-making processes
- International trade relations
Furthermore, it equips individuals with the tools to address pressing global concerns such as climate change, poverty alleviation, and efficient resource allocation.
C. Skills Developed Through IB Economics
Through the IB Economics course, students develop a range of transferable skills highly valued in academic and professional spheres. These include:
- Critical Thinking: Students learn to analyze complex economic situations from multiple perspectives.
- Data Analysis: The course enhances proficiency in interpreting economic indicators, graphs, and statistics.
- Essay Writing: Students cultivate the ability to construct well-structured arguments and evaluations.
- Research Skills: The Internal Assessment (IA) component hones students' capabilities in information gathering, evaluation, and synthesis.
- Application of Theory: The curriculum emphasizes the practical application of abstract economic concepts to real-world scenarios.
- Quantitative Reasoning: While not mathematically intensive, the course improves students' comfort with numerical concepts and calculations.
- Communication Skills: Group work and presentations enhance students' ability to articulate complex ideas clearly and effectively.
D. Career Opportunities
The knowledge and skills acquired through IB Economics open doors to numerous career paths. Graduates may pursue opportunities in fields such as:
- Finance and banking
- Business management
- Government and public policy
- International organizations
- Academia and research
- Law
- Journalism
- Data science
- Environmental management
- Non-profit sector
The analytical and critical thinking skills developed in this course are highly transferable, proving valuable even in fields not directly related to economics.
E. Internal Assessment Component
The IB Economics course includes an Internal Assessment component, which requires students to produce a portfolio of three commentaries based on news articles. (Studying Business Management instead? Its IA is a different beast — see our Business IA structure guide.) This task allows students to demonstrate their ability to apply economic theories to current events, further reinforcing the practical relevance of the course material.

III. IB Economics Internal Assessment (IA) Guide
A. Introduction to the Economics IA
Purpose of the Internal Assessment
The Internal Assessment (IA) is a crucial component of the IB Economics course, designed to evaluate students' ability to apply economic theory to real-world situations. Its primary purposes are:
- To demonstrate understanding of economic concepts and theories
- To develop skills in analyzing current economic events
- To enhance critical thinking and evaluation abilities
- To foster independent research and writing skills
IA Structure and Requirements
The Economics IA consists of a portfolio of three commentaries, each based on a different news article relating to a different section of the syllabus. The key requirements are:
- Word count: Each commentary must not exceed 800 words. (Older guides say 750 — that limit belongs to the previous syllabus.)
- Key concepts: Each commentary must use a different key concept as its analytical lens, chosen from the nine in the current guide — scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence and intervention.
- Currency: Each article must have been published no more than one year before you write its commentary.
- Sources: The three articles must come from three different sources, all recognized news outlets (print or digital).
- Language: Commentaries must be written in the language of instruction of the school.
- Diagrams: Each commentary should include at least one relevant diagram.
Importance in Overall IB Economics Grade
The IA plays a significant role in the overall IB Economics grade:
- Weighting: The portfolio is worth 30% of the final grade at SL and 20% at HL, and is marked out of 45 — 14 marks per commentary plus 3 marks for meeting the portfolio requirements.
- Balancing internal and external assessment: The IA provides an opportunity for students to demonstrate their skills outside of exam conditions, balancing the externally assessed components.
- Skill development: The skills honed through the IA process (analysis, application, evaluation) are crucial for success in the written exams and future academic pursuits.
- University applications: A strong IA can be a valuable addition to university applications, demonstrating research and analytical skills.
B. Selecting Articles for Commentary
Criteria for Suitable Articles
When selecting articles for your IA, ensure they meet the following criteria:
- Currency: published no more than one year before the commentary is written.
- Length: Choose articles that provide enough substance for analysis but are not excessively long.
- Relevance: The article should clearly relate to economic concepts from the IB Economics syllabus.
- Complexity: The article should allow for in-depth analysis and application of economic theories.
- Variety: choose articles that let three different key concepts do genuine analytical work. Spreading your three commentaries across different units of the syllabus remains good practice — but the formal requirement on the current syllabus is the key concept, not the unit.
Sources of Reliable Economic News
Use reputable sources for your articles. Some recommended sources include:
- Financial newspapers: The Financial Times, The Wall Street Journal, The Economist
- International organizations: World Bank, International Monetary Fund (IMF), World Trade Organization (WTO)
- National news outlets: BBC News, Reuters, Associated Press
- Economic journals: Journal of Economic Perspectives, Harvard Business Review
- Central bank publications: Federal Reserve Economic Data (FRED), European Central Bank Economic Bulletin
C. Structure of Each Commentary
Title Page Requirements
- Include your IB candidate code (school will provide this)
- Word count (maximum 800 words)
- Title of the commentary, and the key concept this commentary uses as its lens
Article Information
- Source of the article (publication name)
- Date of the article
- Title of the article
- Author of the article (if available)
- URL link (for online sources)
Body of the Commentary
- Brief Summary of the Article (approximately 50-100 words)
- Explanation of Economic Theory (approximately 150-200 words)
- Application of Theory to the Article (approximately 200-250 words)
- Analysis of the Economic Situation (approximately 200-250 words)
- Evaluation of Policies or Outcomes (approximately 150-200 words)
D. Writing Effective Commentaries
Identifying Key Economic Concepts in the Article
- Read the article multiple times, highlighting economic terms and concepts.
- Look for explicit economic ideas (e.g., inflation, supply and demand) and implicit ones (e.g., opportunity cost in policy decisions).
- Consider both microeconomic and macroeconomic perspectives where relevant.
- Identify the main economic problem or issue the article is addressing.
Linking Theory to Real-World Situations
- Clearly state the relevant economic theories or models.
- Explain these theories concisely but thoroughly.
- Draw explicit connections between the theory and specific details in the article.
- Use economic terminology accurately and consistently.
- Demonstrate how economic theory helps explain or predict the situation described in the article.
E. Diagrams and Data Presentation
Importance of Relevant Diagrams
- Visual representation: Diagrams help clarify and reinforce economic concepts.
- Analysis tool: Use diagrams to analyze changes or compare different scenarios.
- IB requirement: At least one diagram is required for each commentary.
- Demonstration of skills: Well-executed diagrams show your ability to apply economic theory.
Types of Diagrams Commonly Used in Economics IA
- Supply and Demand Diagrams
- Production Possibility Frontier (PPF)
- Cost Curves

F. Common Pitfalls and How to Avoid Them
Exceeding the Word Limit
Problem: Going over the 800-word limit for each commentary.
How to avoid:
- Plan your commentary structure carefully before writing.
- Be concise in your language, avoiding unnecessary repetition.
- Focus on analysis rather than description.
- Use diagrams effectively to reduce the need for extensive written explanations.
- Leave time for editing and trimming your work.
Lack of Economic Theory
Problem: Failing to incorporate sufficient economic concepts and theories.
How to avoid:
- Identify key economic concepts in the article before starting your commentary.
- Explicitly state and explain relevant economic theories.
- Use economic terminology consistently throughout your work.
- Ensure every paragraph includes some application of economic theory.
- Review the IB Economics syllabus to ensure you're covering a range of concepts across your three commentaries.
Working With an Economics Tutor on Your IA
Q1: How can an IB Economics tutor help me with my IA?
An IB Economics tutor can provide valuable support in several ways:
- Clarifying complex economic concepts and theories relevant to your chosen articles.
- Guiding you in selecting appropriate articles that allow for rich economic analysis.
- Helping you structure your commentaries effectively.
- Providing feedback on your analysis and evaluation (within IB guidelines).
- Assisting with time management and planning for your IA.
- Offering practice in applying economic theories to real-world situations.
- Helping you improve your diagramming skills.
- Advising on common pitfalls to avoid in your IA.
Remember, while a tutor can provide guidance and support, the work must be your own to comply with IB regulations.
Q2: How often should I meet with an IB Economics tutor for IA support?
The frequency of meetings can vary based on your needs, but a common approach is:
- Initial meeting: To discuss the IA requirements and create a plan.
- Article selection stage: 1-2 sessions to help choose appropriate articles.
- Planning stage: 1 session per commentary to outline your approach.
- Draft review: 1 session per commentary to discuss your draft (ensuring compliance with IB rules on feedback).
- Final review: 1 session to review your complete portfolio before submission.
Always check with your school about their policies on external tutoring.
Q3: Can my teacher or tutor edit my IA?
No, neither your teacher nor a tutor should edit your work directly. They can provide general feedback on areas for improvement, but the actual writing and revising must be your own work. This is a strict IB requirement to ensure academic honesty.
Q4: How do I choose the best articles for my IA?
Look for articles that:
- Clearly relate to economic concepts from the IB syllabus.
- Are from reputable sources and published within the last year.
- Provide opportunities for in-depth economic analysis.
- Cover different areas of the syllabus for each of your three commentaries.
- Include some data or policy discussions that you can evaluate.
A tutor can help you identify suitable articles and explain why they would work well for your IA.
Q5: How important is the IA in my overall IB Economics grade?
The IA is worth 30% of your final grade at SL and 20% at HL — at Standard Level, nearly a third of your grade is decided outside the exam hall. The remaining 70% (SL) or 80% (HL) comes from the final papers, so a tutor can help you balance IA drafting against exam revision.
IB Economics IA: Frequently Asked Questions
How long is each IB Economics commentary?
Up to 800 words each, for three commentaries. Older guides say 750 — that limit belongs to the previous syllabus. Diagrams, their labels, and the bibliography sit outside the count, so spend your words on analysis and evaluation rather than describing the article.
What are the nine key concepts in IB Economics?
Scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence and intervention. Each of your three commentaries must use a different one as its analytical lens, and the concept should visibly organise the commentary rather than appear once in the introduction.
How is the Economics IA marked?
Out of 45: each commentary is marked out of 14, and a further 3 marks are awarded for meeting the portfolio requirements — three different key concepts, articles from three different sources, and each article published no more than a year before its commentary was written.
How much is the Economics IA worth?
30% of the final grade at Standard Level and 20% at Higher Level. The older figure of 20% for both levels belongs to the previous syllabus — at SL, the IA now carries nearly a third of your grade, which changes how much attention it deserves.
What makes a good article for an Economics commentary?
Recent (under a year old when you write), from a recognised news source, short enough to stay focused, and rich enough to let one key concept and one diagram do real analytical work. An article that merely mentions an economic term is weaker than one describing a change you can model.
