The Ultimate IB Economics Guide: What to Know Before Choosing

Thinking about a career in finance, policy, law or business? The subjects you choose now can shape those paths, from the degrees you apply for to the skills you bring to university. IB Economics is a strong starting point, but what does the course involve?

‍

IB Economics is a Diploma Programme subject applying models and data to real-world issues. You'll sit two papers at SL or three at HL, plus an internal assessment: three commentaries, each analysing a news article through a different key concept.

‍

In this guide, we'll discuss its syllabus, nine key concepts, assessment, HL versus SL and where the subject can lead.

‍

First, here's a quick summary of the essentials.

Key takeaways

• IB Economics is a Group 3 Diploma subject with four units: introduction to economics, microeconomics, macroeconomics and the global economy. Nine key concepts, from scarcity to intervention, link them all.
• Exams count for 70% at SL and 80% at HL. The rest comes from the internal assessment: three news-based commentaries, each using a different key concept.
• HL adds 90 teaching hours and topics like behavioural economics and market power. It also includes Paper 3, a policy paper worth 30%.
• Choose HL if you're aiming for economics, finance or PPE and enjoy working with data. SL suits students heading towards law or international relations.
• Results are strong: in May 2026, HL candidates averaged 5.2 and SL candidates 5.0, above the 4.9 Diploma-wide mean.
• The subject supports degrees in economics, PPE, business, and law, though selective economics courses also require strong HL Maths. Common careers include being an economist, financial analyst and policy adviser.

What is IB Economics?

IB Economics is a Group 3 (individuals and societies) subject in the IB Diploma Programme, taken at SL or HL, that analyses real-world issues through economic models and data.

‍

In the sections below, we'll discuss the four units and nine key concepts that shape the course.

The four syllabus units 

The IB Economics syllabus is split into four units, building from core economic ideas to individual markets, national economies and the global economy.

‍

Here's what each unit covers.

• Unit 1: introduction to economics. Scarcity sits at the heart of this unit, which runs for 10 teaching hours at both levels. You'll learn opportunity cost, the production possibilities curve and the circular flow of income.
• Unit 2: microeconomics. Sugar taxes, rent caps and minimum prices all feature here. You'll study demand, supply and elasticity, then market failures like pollution and public goods. HL adds market power and behavioural economics.
• Unit 3: macroeconomics. How do central banks bring inflation down? This unit uses the AD/AS model to evaluate monetary, fiscal and supply-side policies. It also measures inequality through the Lorenz curve and Gini coefficient.
• Unit 4: the global economy. At 45 hours for SL and 65 for HL, it's the largest unit at SL. It covers trade protection, exchange rates and the balance of payments. The second half explores uneven economic development, using indicators like the Human Development Index.

The nine key concepts that tie it together

While the units divide the content, nine key concepts link them, letting you view one issue, like a carbon tax, through several lenses.

‍

Here are the nine concepts and what each one means.

• Scarcity: there's never enough time, money or resources for everything people want and need, so something always has to give.
• Choice: picking one option means giving up another, and the value of what you give up is called opportunity cost.
• Efficiency: getting the most out of what you have, so nothing is wasted and people get what they actually value.
• Equity: whether income, wealth and opportunities are shared fairly, and what governments can do when some people are left behind.
• Economic well-being: how well people are really living, from affording everyday essentials to feeling secure about their long-term financial future.
• Sustainability: using natural resources today in a way that still leaves enough for future generations to meet their own needs.
• Change: economies never stand still, so economists focus on what shifts, like rising prices or new technology replacing certain jobs.
• Interdependence: everyone in an economy relies on others, so a decision made in one country can affect people far away.
• Intervention: when governments step into markets with taxes, subsidies or rules to fix problems markets can't solve on their own.

How is IB Economics assessed?

IB Economics is assessed by combining external exams, worth 70% of your grade at SL and 80% at HL, with a teacher-marked internal assessment making up the rest.

‍

In the sections below, we'll break down each exam paper and explain how the internal assessment works.

Paper 1 and Paper 2 (SL and HL)

Both SL and HL students sit Paper 1 and Paper 2, which draw on all four units but test different skills: extended writing and data analysis.

‍

Here's how the two papers compare.

Paper 3: the HL policy paper

Paper 3 is the HL-only policy paper, lasting 1 hour 45 minutes and worth 30% of your grade. It draws on all four units, combining calculations with written economic analysis.

‍

The paper asks you to think like a policymaker. You’ll answer two compulsory questions, each ending with a data-backed policy recommendation. One IB sample question, for example, asks you to recommend a government response to falling world coffee prices.

The internal assessment (IA)

The IA for IB Economics is a portfolio of three commentaries, worth 20% at HL and 30% at SL. Its news-based format sets Economics apart from most IB subjects.

‍

Each commentary analyses a recent news article on a different unit: microeconomics, macroeconomics or the global economy. You use diagrams to explain the economics involved, then evaluate the issue through a key concept.

‍

You must use a different concept each time, and each commentary must stay within 800 words. Then, your teacher marks the portfolio before the IB moderates it.

IB Economics HL vs SL: which should you choose?

The right level depends on your university plans, your comfort with calculations and how IB Economics fits alongside your other subjects.

‍

In the next sections, we'll explain what HL adds and help you decide which level suits you best.

What HL adds

Aside from the additional paper, HL adds extra content across microeconomics, macroeconomics, and the global economy. To make room for it, teaching time rises from 150 hours at SL to 240 at HL.

‍

In microeconomics, for example, you’ll study behavioural economics, which explores why people don’t always act rationally. That includes common biases and how nudges, like default options, shape everyday choices. You’ll also cover market power, which examines how monopolies and oligopolies set prices.

‍

HL also adds calculations and diagrams to shared content, such as the Keynesian multiplier and the J-curve.

How to decide

The right level depends on your university plans, your comfort with calculations and the workload of your other HL subjects.

‍

Here's a simple way to weigh it up.

• Choose HL if you're aiming for economics, finance or PPE at university, enjoy working with graphs and data, and can manage 90 extra hours alongside your other HL subjects.
• Choose SL if economics supports rather than drives your plans, as with law or international relations degrees. It's also the smarter option if your HL slots are better spent on subjects your degree requires.

Is IB Economics hard?

IB Economics is demanding, especially at HL, where you combine essay writing, diagrams and calculations across three exam papers. The real challenge is applying theory to unfamiliar, real-world situations rather than memorising definitions.

‍

Still, results are strong. According to the IB Diploma Programme Statistical Bulletin (May 2026), Economics HL candidates averaged 5.2, while SL candidates averaged 5.0. Both beat the overall mean grade of 4.9 across Diploma candidates.

Where IB Economics can lead

IB Economics builds a strong foundation for degrees in the social sciences, business and law, plus analytical careers. Economics itself is the most direct route, though selective courses usually expect strong HL Maths too.

‍

It also supports Philosophy, Politics and Economics (PPE), which blends economic analysis with political theory and ethics. Business, finance and management degrees apply ideas like elasticity and market power to how real firms compete.

‍

Even law and international relations draw on economic thinking, through topics like competition law and trade agreements. Beyond university, common roles include economist, financial analyst, policy adviser, management consultant and data analyst.

Explore economics with Immerse Education

Committing to IB Economics, especially at HL, is a big decision to make before you've studied the subject. It's hard to know whether you'll enjoy diagrams, data and policy debates until you've tried them.

‍

Our Economics Summer School, open to ages 13-18, lets you test that interest first. Over two weeks in Oxford, Cambridge, London or Singapore, you'll explore game theory, trade and development with expert tutors.

‍

You'll also complete a personal research project, a useful rehearsal for the real-world analysis the IA demands. By the end, you'll know whether economics is a subject you want to take further, at IB and beyond.
