20 Topic Ideas for Economics IA

How to Choose the Right Economics IA Topic

Choosing the right topic is one of the most important decisions in your IB Economics IA portfolio. Each of your three commentaries must be based on a different section of the syllabus — microeconomics, macroeconomics, and the global economy — and each must connect to a different key concept from the course (scarcity, choice, efficiency, equity, economic well-being, sustainability, change, interdependence, and intervention). You may also find our resource on IB economics syllabus new pattern changes helpful. (This guide has been for 2025-26 submissions.)

The best IA topics are specific enough to analyse in depth within the 650-to-800-word limit, clearly connected to identifiable economic theory, and supported by an article that contains data and real-world details you can reference. This guide presents 20 proven topic areas across all three syllabus sections, with guidance on which economic concepts, diagrams, and analytical approaches work best for each. If you're struggling to identify strong topics from real-world sources, or if you want feedback on whether your chosen article will support robust analysis, a tutor can help.

Microeconomics Topics

1. Changes in Market Demand

Find an article about a significant shift in demand for a product or service caused by a non-price factor (changes in income, tastes, population, or the price of substitutes and complements). Show the demand shift on a supply-and-demand diagram, analyse the new equilibrium price and quantity, and discuss the effects on consumers, producers, and employment in the industry. A strong evaluation might consider the elasticity of supply and how quickly the market adjusts.

2. Changes in Market Supply

Supply shifts are frequently newsworthy — disruptions to oil production, agricultural harvests affected by weather, or supply chain issues. Identify the non-price factor causing the supply shift, show the effect on market equilibrium, and analyse the consequences for consumers (higher prices) and producers (changed revenue). Evaluate how the market might adjust over time and whether government intervention is warranted.

3. Indirect Taxation

Articles about new taxes on specific products (sugar taxes, carbon taxes, tobacco excise duties) provide excellent IA material. Identify whether the tax is specific or ad valorem, show the effect on price and quantity using a diagram with the tax wedge, and analyse the burden of taxation on consumers versus producers (linking to elasticity). For HL students, include a discussion of changes in consumer and producer surplus and welfare loss.

4. Government Subsidies

Subsidies on essential goods, renewable energy, or agriculture are commonly reported. Show how the subsidy shifts supply, lowers market price, and increases quantity. Analyse the effects on consumers (lower prices), producers (higher revenue), and the government budget. Evaluate whether the subsidy achieves its intended purpose and discuss potential welfare loss from overproduction.

5. Negative Externalities and Corrective Policies

Articles about pollution taxes, congestion charges, or regulations on demerit goods work well here. The key is to show the market failure (where marginal social cost exceeds marginal private cost) and then demonstrate how the government intervention aims to reduce output to the socially optimal level. Identify whether the externality is in production or consumption, and evaluate whether the policy fully corrects the market failure.

6. Positive Externalities and Government Support

Look for articles about government investment in education, healthcare, or eco-friendly technologies. Show the market failure (underprovision due to external benefits not captured by the market) and how subsidies or direct provision aim to increase consumption to the socially optimal level. Evaluate the effectiveness of the intervention and whether it creates any unintended consequences.

7. Monopoly Power and Regulation

Articles about competition authorities investigating dominant firms, breaking up monopolies, or imposing regulations on pricing provide strong IA material. Analyse why monopoly power leads to allocative inefficiency (price above marginal cost), its effects on consumers and the broader market, and evaluate the proposed regulatory response. This topic requires careful focus to stay within the word limit.

8. Price Controls (Ceilings and Floors)

Rent controls, minimum wage legislation, and agricultural price supports are all examples of price controls frequently covered in the news. Show the effect of the price ceiling or floor on quantity demanded and quantity supplied, identify the resulting shortage or surplus, and analyse the consequences for different stakeholders. Evaluate the effectiveness of the policy and consider alternative approaches.

Macroeconomics Topics

9. Economic Growth

An article reporting GDP growth for a specific country provides straightforward IA material. Show the increase in real GDP using an AD/AS diagram (a rightward shift of AD or AS), analyse the effects on employment, income, and government revenue, and evaluate potential downsides such as demand-pull inflation or environmental degradation. Ensure you use specific data from the article to support your analysis.

10. Recession and Negative Growth

Articles about economic contraction or recession (two consecutive quarters of negative GDP growth) are rich in analytical potential. Show the recessionary gap on an AD/AS diagram, analyse the effects on unemployment, income, tax revenue, and economic well-being, and evaluate what fiscal or monetary policy responses might help close the gap.

11. Changes in Unemployment

Rising or falling unemployment rates are regularly reported. Identify the type of unemployment (cyclical, structural, frictional, or seasonal) and connect it to the macroeconomic context using an AD/AS diagram. Analyse the social and economic consequences and evaluate the government policies that could address the issue, distinguishing between demand-side and supply-side approaches.

12. Demand-Pull Inflation

When an economy overheats and prices rise due to excessive aggregate demand, show this using a Keynesian AD/AS diagram with output beyond full employment. Analyse the effects of inflation on purchasing power, savings, investment, and different groups in society (borrowers versus lenders, fixed-income earners). Evaluate the appropriate monetary or fiscal policy response.

13. Cost-Push Inflation

Supply shocks — rising energy prices, raw material shortages, or wage increases — can cause cost-push inflation (stagflation). Show the leftward shift of SRAS on a monetarist AD/AS diagram, analyse the simultaneous rise in prices and fall in output, and evaluate policy options. This is a particularly strong topic because the policy dilemma (fighting inflation versus fighting recession) provides excellent evaluation material.

14. Fiscal Policy Changes

Articles about government budgets, tax reforms, or major public spending programmes provide clear fiscal policy material. Identify whether the policy is expansionary or contractionary, show its effect on aggregate demand using a diagram, and analyse the intended and potential unintended consequences. Evaluate the effectiveness of the policy and consider time lags, crowding out, and the multiplier effect.

15. Monetary Policy Changes

Central bank decisions to raise or lower interest rates are widely reported and make excellent IA topics. Identify whether the change is expansionary or contractionary, explain the transmission mechanism (how interest rate changes affect consumption, investment, and aggregate demand), and show the effect on the macroeconomy using a diagram. Evaluate the effectiveness of the policy, considering time lags and the impact on different sectors.

16. Income Inequality and Redistribution

Articles about changes in income tax rates, welfare programmes, or wealth distribution provide material for analysing equity and redistribution. Discuss the trade-off between equity and efficiency, analyse the effects of the policy on different income groups, and evaluate whether the intervention improves economic well-being without significantly reducing incentives for productivity.

Global Economy Topics

17. Trade Protection (Tariffs and Quotas)

Trade protection is consistently newsworthy and provides some of the strongest IA material available. Use the tariff diagram to show the effects on domestic price, domestic production, imports, consumer surplus, producer surplus, government revenue, and welfare loss. Analyse the impact on different stakeholders and evaluate whether the protectionist measure achieves its stated aims.

18. Exchange Rate Changes

Significant currency appreciations or depreciations provide clear analytical opportunities. Show the exchange rate change on a currency market diagram, analyse the effects on exports, imports, the balance of trade, and inflation, and evaluate how the central bank might respond. Consider the J-curve effect for a more sophisticated evaluation.

19. Export Development and Infant Industry Protection

Articles about government support for emerging industries — particularly in developing economies — provide material connecting trade theory to development economics. Analyse how subsidies or protection support domestic industry growth, the effects on employment and GDP, and whether the strategy is sustainable in the long run. Evaluate the arguments for and against infant industry protection.

20. Economic Development Initiatives

Articles about foreign aid, microfinance programmes, infrastructure investment, or education initiatives in developing countries connect to the global economy section. Analyse how the initiative aims to improve standards of living and economic well-being, using relevant development indicators. Evaluate the effectiveness of the approach and consider alternative strategies for promoting sustainable development.

Tips for Selecting Your Final Topics

Match Topics to Available Articles

No matter how promising a topic area seems, you need an actual published article to base your commentary on. Search for articles before committing to a topic. The best articles contain specific data (numbers, percentages, monetary values) that you can reference in your analysis.

Ensure Variety Across Your Portfolio

Beyond covering the three required syllabus sections, aim for variety in the economic tools and diagrams you use. If your microeconomics commentary uses supply and demand, consider using an AD/AS model for macroeconomics and a tariff diagram for the global economy. This variety demonstrates breadth of economic understanding.

Choose Topics You Understand Well

The word limit is tight, and there is no room for confusion or vague explanations. Select topics where you are confident in the underlying economic theory and can explain it clearly and accurately. A well-executed commentary on a straightforward topic will outscore a confused attempt at a more complex one. Explore our detailed guide on scoring a 7 in Math HL for more tips.

Common Mistakes to Avoid

1. Choosing articles that are too broad

An article covering multiple economic issues simultaneously makes it difficult to maintain analytical focus within 800 words. Choose articles that centre on a single, identifiable economic event or policy.

2. Selecting opinion pieces instead of news reports

Opinion articles often do the economic analysis for you, leaving you little room to demonstrate your own analytical skills. Choose factual news reports that describe what happened, leaving the economic analysis to you.

3. Picking topics without diagram potential

Diagrams are worth significant marks. Before committing to a topic, ensure you can draw at least one clear, relevant diagram that directly supports your analysis. Topics that do not lend themselves to diagrammatic representation are generally poor IA choices.

4. Leaving article selection until the last minute

Finding the right article takes time. Start searching early and save promising articles as you encounter them throughout the course. Having a collection of potential articles gives you the flexibility to choose the best options when it is time to write.

5. Using all three commentaries on similar economic concepts

Even though each commentary covers a different syllabus section, students sometimes gravitate toward similar analytical approaches in all three (for example, always focusing on supply and demand shifts). Deliberately vary your approach to showcase the full range of your economic understanding.

Frequently Asked Questions

How do I decide between microeconomic and macroeconomic topics for my Economics IA?

Microeconomic topics examine individual agents—consumers, firms, specific markets—and explore concepts like elasticity, market structures, or consumer behaviour; these topics work well if you're interested in business decisions, pricing strategies, or individual market dynamics. Macroeconomic topics investigate national-level phenomena—inflation, unemployment, exchange rates, economic growth—offering opportunities to analyse policy interventions and international economic relationships. Choose based on genuine interest rather than perceived difficulty; a well-executed microeconomic commentary on something you care about will outscore forced macroeconomic analysis. Consider which topic allows you to find accessible, relevant articles; the best topic remains theoretical if suitable source materials are unavailable. Many successful portfolios blend both approaches, selecting one strong microeconomic and one macroeconomic commentary alongside a third addressing either domain.

What strategies help me locate suitable articles for meaningful economic analysis?

Begin by reading reputable economic publications—The Economist, Financial Times, The Guardian's economics section, BBC Business—to familiarise yourself with current economic issues and the language economists use. Identify topics sparking your genuine curiosity, then search news archives or economic databases using keywords combining the topic and economic concepts (e.g., "minimum wage effects unemployment" or "cryptocurrency regulation"). Verify articles discuss economics substantively rather than merely mentioning economic terms; a 500-word article genuinely exploring economic principles works better than a 2,000-word piece lacking analytical depth. Archive URLs for future reference, noting publication date and source, which proves invaluable when you later need to cite your sources. Avoid overused examples featured in widely-available IB study guides; selecting less-obvious articles often produces more distinctive commentaries and prevents unconscious plagiarism of others' analyses.

Should I select original or popular economic topics, and how does this choice affect my portfolio quality?

Original topics—ones you've discovered yourself—often produce more authentic, engaged analysis simply because your genuine curiosity drives investigation rather than selecting a pre-approved option. However, "popular" topics like cryptocurrency, climate change economics, or globalisation aren't inherently problematic; what matters is your specific analytical angle and the particular source material chosen. If analysing a popular topic, ensure your chosen article and economic analysis offer fresh perspectives rather than recycling standard arguments found in every student's portfolio. Conversely, avoid selecting obscure topics purely for perceived originality if you lack genuine interest or cannot locate adequate source materials. Your portfolio quality depends fundamentally on the depth and sophistication of your economic analysis, not on whether your chosen topics appear frequently across international schools.

How should I assess whether a potential topic is feasible and contains sufficient economic content?

Before committing to a topic, locate at least two strong articles discussing it and read them thoroughly, ensuring they contain genuine economic analysis rather than purely journalistic description. Consider whether the topic relates clearly to specific IB economics concepts you've studied—supply and demand, market failure, development indicators, monetary policy—so you'll have theoretical frameworks to apply. Assess whether the topic allows for both content analysis and critical evaluation; strong commentaries go beyond describing what happened to explaining why, using economic theory to provide insight. Finally, consider your access to relevant data or articles; topics requiring specialised academic sources you cannot access will prove frustrating. A feasible topic is one where excellent articles exist, economic analysis is possible, and you can meaningfully engage with the ideas presented.

What common pitfalls should I avoid when selecting and analysing Economics IA topics?

A frequent error is selecting articles lacking sufficient economic content, resulting in commentaries that merely summarise news rather than analyse economics; ensure your chosen article explicitly discusses economic concepts and their implications. Avoid topics where you lack genuine interest; disengaged writing typically results in superficial analysis regardless of intellectual capability. Some students select articles but then ignore them, instead writing prepared paragraphs about the economic concept independent of the stimulus; examiners expect your commentary to engage specifically with your chosen article's content and context. Another pitfall is selecting multiple articles on nearly identical topics, resulting in repetitive commentary; diversify your portfolio across different economic domains and issues. Finally, avoid overly technical topics requiring mathematical modelling beyond IB curriculum scope or concepts from advanced university economics; accessibility and demonstrated understanding matter more than apparent sophistication.

How can I identify distinctive topic selections and sources that elevate my portfolio above typical IB Economics submissions?

Challenge yourself to identify emerging or under-discussed economic issues rather than selecting topics featured in economics textbooks; reading current economic publications, policy reports, and emerging research helps you discover fresh angles. Consider selecting articles from economists and publications reflecting diverse perspectives—incorporating voices from developing economies, heterodox economists, or critics of mainstream approaches—which demonstrates sophisticated understanding of economic debate. Ensure your three commentaries collectively span different economic themes (labour markets, financial systems, development, trade) rather than clustering around closely related topics, which shows breadth of knowledge. In your analytical writing, move beyond textbook definitions by engaging with real-world complexity; acknowledge assumptions underlying economic models and discuss where real situations diverge from theoretical predictions.
