The IB Economics Internal Assessment (IA) can feel like a daunting hurdle, but it's actually a fantastic opportunity to showcase your understanding of economic theory in a real-world context. As someone who scored a 7 on the Economics IA and achieved an IB 45, I can tell you that the key isn't just knowing the content, but knowing how to apply it precisely and analytically. This guide distills my experience, from selecting articles to crafting the perfect evaluation, specifically for international students aiming for top universities.
Unlike the external exams, the IA allows you to explore an economic issue you genuinely find interesting. This personal connection can be a powerful motivator. My own IA focused on the economic implications of Japan's 'Cool Biz' initiative, linking microeconomic concepts like externalities and behavioural economics to a government policy. This guide will walk you through the process, providing actionable advice that goes beyond generic tips, drawing from my experience applying to Cambridge, HKU, and HKUST.
Understanding the IA Requirements & Rubric
Before you even think about choosing an article, internalize the IA rubric. This is your blueprint for success. The IB Economics IA requires three commentaries, one for each economic unit: Microeconomics, Macroeconomics, and Global Economy. Each commentary must be based on a different news article published no more than one year before the date you write the commentary. The word count is strict: 800 words per commentary, excluding diagrams, tables, and bibliography. Exceeding this will be penalized.
The rubric assesses five key criteria: Diagrams (2 marks), Terminology (2 marks), Application and Analysis (10 marks), Evaluation (6 marks), and Citing, referencing and word count (3 marks). Notice that 'Application and Analysis' and 'Evaluation' combined account for 16 out of 25 marks. This tells you where your focus needs to be: not just describing theory, but applying it to your chosen article and critically assessing its implications and limitations. Many students lose marks by simply defining terms without linking them explicitly to the article's context.
Choosing Your Articles Wisely
This is arguably the most crucial first step. A poor article choice can make the entire IA process an uphill battle. Look for articles that clearly discuss an economic event or policy and offer scope for analysis using specific economic theories. Avoid articles that are purely descriptive or too broad. For example, an article about 'global inflation' is too vague; one discussing 'the impact of the Bank of England's interest rate hike on UK housing prices' is much better.
Sources matter. Reputable news outlets like The Economist, Financial Times, Wall Street Journal, BBC News, Bloomberg, and Reuters are excellent. Local newspapers can also work, especially for microeconomic issues in your region. The key is finding an article with enough depth to allow for sustained economic analysis. Don't pick an article just because it mentions 'supply and demand'; ensure it presents a problem or policy that can be rigorously analyzed using IB-level concepts. Remember, each article must be distinct enough to allow for a different economic unit focus.
Structuring Your Commentary: The I-D-A-E-L Approach
I found a consistent structure incredibly helpful. Think of it as I-D-A-E-L: Introduction, Diagrams, Application & Analysis, Evaluation, and Link to the article/conclusion. Your introduction should briefly summarize the article and state the economic concept(s) you will be using. Immediately after, integrate your diagrams. These aren't just decorative; they are integral to your analysis.
The bulk of your commentary will be 'Application & Analysis.' This is where you explain the economic theory, link it directly to the events in your article, and explain the cause-and-effect relationships. For example, if discussing a carbon tax, don't just define negative externalities; explain how the tax internalizes the externality, shifts the supply curve, and impacts market equilibrium, using specific data or details from your article. Finally, your 'Evaluation' section is critical for higher marks. This is where you discuss limitations of your analysis, alternative policies, short-term vs. long-term impacts, stakeholders affected, and real-world complexities. Conclude by briefly linking back to the article's main point and summarizing your economic findings.
Mastering Diagrams and Terminology
Diagrams are worth 2 marks, but they are often the foundation for your analysis. They must be accurately drawn, fully labelled (axes, curves, equilibrium points), and directly referenced and explained in your text. Don't just plop a diagram in; explain what it shows, how it relates to the article, and what shifts or movements occur. For instance, if discussing a price ceiling, draw the ceiling below equilibrium, show the resulting shortage, and explain its implications.
Economic terminology (2 marks) is about precision. Use correct, formal economic language throughout. Define key terms when you introduce them, but don't overdo it. The goal is to demonstrate understanding through application, not just rote memorization of definitions. For example, instead of saying 'the government helped poor people,' use 'the government implemented a targeted subsidy to improve equity and address market failure.' This demonstrates both correct terminology and conceptual understanding.
Deep Diving into Application and Analysis (10 Marks)
This is where you earn most of your marks. It's not enough to state 'the article talks about inflation.' You need to explain *why* inflation is occurring using specific macroeconomic models (e.g., AD/AS shifts due to increased money supply or supply-side shocks), *how* it impacts different economic agents (consumers, firms, government), and *what* the potential consequences are. Use data or specific examples from your article to support your points.
Think about the chain of reasoning. If a government imposes a tariff, don't just say 'it raises prices.' Explain how the tariff shifts the supply curve of imports, increases the domestic price, reduces quantity demanded, impacts consumer surplus, producer surplus, government revenue, and potentially leads to deadweight loss. Always link back to the article's context. For example, 'As the article states, the 25% tariff on steel imports from China led to a 15% increase in domestic steel prices, as depicted by a leftward shift of the import supply curve from S_import to S_import+tariff in Diagram 1, reducing consumer surplus by X amount...'
Excelling in Evaluation (6 Marks)
Evaluation is what separates a good IA from an excellent one. This is where you demonstrate critical thinking. Don't just re-state your analysis. Consider the limitations of your chosen policy or economic theory. Are there unintended consequences? What are the short-term versus long-term effects? Who are the winners and losers (stakeholder analysis)? Are there alternative policies that could be more effective? What assumptions are being made in your analysis?
For example, if you're analyzing a minimum wage increase, an evaluation might discuss: the potential for job losses (elasticity of demand for labour), the impact on small businesses versus large corporations, the possibility of an informal labour market developing, the inflationary pressure, or the difficulty of setting an optimal minimum wage. Always strive for balance and nuance. Acknowledge complexities and avoid making definitive, overly simplistic conclusions. Use phrases like 'However, it is important to consider...', 'A potential drawback is...', 'Alternatively, the government could have considered...'.
Citing, Referencing, and Word Count Management
These are easy marks if you're diligent. Ensure you cite your news article correctly in a bibliography using a consistent style (e.g., MLA, APA). Any external sources you use for definitions or background must also be cited. The word count (800 words per commentary) is strict. Go over, and you'll be penalized. Go under significantly, and you likely haven't provided enough depth.
My strategy for word count management was to write a full draft, then meticulously edit. Cut redundant phrases, combine sentences, and ensure every word contributes to your analysis or evaluation. Diagrams, titles, and bibliography do not count towards the word limit. Be ruthless in your editing; clarity and conciseness are highly valued.
Final Tips from an IB 45 Student
Start early. Don't leave article selection or writing until the last minute. Give yourself time to find good articles, draft, get feedback from your teacher, and revise. My teachers at my international school in Tokyo were invaluable in providing guidance on my drafts, helping me refine my arguments and ensure I met all rubric requirements. Take advantage of their expertise.
Read examples of high-scoring IAs, if available, but use them as inspiration, not templates for copying. Focus on understanding *why* they scored well. Practice linking theory to real-world examples constantly, even outside of your IA. This skill is transferable to the exams and crucial for university-level economics. Remember, the IA is a marathon, not a sprint. Consistent effort and meticulous attention to detail will pay off.
