The International Economics Olympiad (IEO) and Economics Olympiad (EO) are two international economics competitions for high school students. In this article, Aralia breaks down the key differences between the two competitions, including eligibility requirements, subject areas, competition formats, and the selection process. We also compare their relative difficulty, highlight the strengths of each competition, and explain which type of student may be a better fit for each one.
Although the two competitions have similar names, the International Economics Olympiad (IEO) and Economics Olympiad (EO) are distinct competitions. Both are designed for high school students interested in economics and include competition stages at the national and international levels. They also share a common goal: helping students develop economic reasoning, analytical thinking, and problem-solving skills.
To make the distinction clear throughout the article, Aralia will refer to the two competitions as the International Economics Olympiad (ieo-official.org) and the Economics Olympiad (economicsolympiad.org).
1. What Is the International Economics Olympiad (IEO)?
The International Economics Olympiad (IEO) is an annual international competition for high school students that focuses on three core areas: economics, finance, and business.
Rather than simply testing students’ ability to memorize economic concepts, the IEO challenges students to apply their knowledge, analyze data, solve open-ended problems, and develop solutions to real-world business scenarios.
The IEO is also supported by prominent economists and academics, including Eric Maskin, who received the Nobel Prize in Economics in 2007. According to the official IEO website, the competition currently consists of three main components:
- Multiple-Choice Test: This section assesses students’ knowledge and application of concepts in Economics and Finance. Under the 2026 IEO format, the test consists of 40 multiple-choice questions.
- Open Questions: Students answer a series of open-ended questions designed to evaluate their ability to explain concepts, develop logical arguments, and apply economic knowledge to different problems.
- Business Case: This is a team-based component in which students analyze a business case, develop a proposed solution, and present their recommendations to a panel of judges.

2. What Is the Economics Olympiad (EO)?
The Economics Olympiad (EO) is a competition for high school students that was founded in the Czech Republic in 2016 by the Institute of Economic Education (INEV). The competition aims to strengthen students’ understanding of economics and finance while helping them explore how economic principles can be applied to real-world issues.
The Economics Olympiad is open to students between 14 and 20 years old and does not require participants to have a formal background in economics. This makes EO relatively accessible to students who are just beginning to explore the subject.
Since its launch in 2016, the Economics Olympiad has expanded to multiple countries, with more than 80,000 students participating each year across 22 countries and four continents.
One important distinction for students and parents to keep in mind is that the Economics Olympiad also uses the name “International Economics Olympiad” on its official website. This can easily lead to confusion between EO and the separate International Economics Olympiad (IEO) discussed above.
What Does the Economics Olympiad Cover?
According to the official curriculum, the Economics Olympiad focuses primarily on economics and financial literacy. Key areas include principles of ecnomics, history of economics, micro and macro-economics, international economics, contemporary economic issues and financial literacy

4. How Do the Competition Topics Differ?
This is one of the most important differences between the Economics Olympiad (EO) and the International Economics Olympiad (IEO). Both competitions require students to have knowledge of economics and finance, but they differ significantly in the breadth of their content and how they assess students’ abilities.
Economics Olympiad
The Economics Olympiad curriculum is built around foundational concepts in economics and financial literacy. Students are expected to understand core economic principles, how markets function, how economic policies affect the economy, and fundamental financial concepts. The official EO curriculum is based on terminology and subject areas commonly found in standard economics textbooks and introductory courses.
This gives the Economics Olympiad a distinct educational focus. Students do not necessarily need to have studied economics beforehand to begin preparing for the competition. For many students, preparing for and participating in EO can serve as an opportunity to build their foundational knowledge and explore economics for the first time.
International Economics Olympiad
The International Economics Olympiad, on the other hand, evaluates a broader range of knowledge and skills. Its content is divided into three main areas:
Part 1 – Economics
This section covers Economic Principles, Microeconomics, Macroeconomics, International Economics, as well as emerging areas of research in economics.
Topics range from supply and demand, consumer choice, firm behavior, and market structures to game theory, monetary policy, economic growth, international trade, and environmental economics.
Part 2 – Financial Literacy
Students are expected to understand topics including financial planning, banking, saving, credit, investing, financial instruments, risk management, insurance, financial fraud, Ponzi schemes, crowdfunding, and cryptocurrencies.
Part 3 – Business
Business is one of the areas that sets the IEO apart from the Economics Olympiad. This section covers the business environment, companies, stakeholders, management and leadership, human resources, marketing, operations, finance and accounting, and strategic management.
Beyond subject knowledge, the IEO also challenges students to apply their knowledge to practical situations. Success requires a combination of analytical thinking, conceptual thinking, quantitative reasoning, and communication skills, particularly when students are asked to work through complex, real-world problems.

5. Which Competition Is More Difficult?
Because the two competitions have different exam formats, structures, and assessment methods, it is difficult to make a general statement about which one is harder.
However, when looking specifically at the breadth and depth of subject knowledge, the International Economics Olympiad (IEO) may be considered somewhat more challenging. In addition to multiple-choice questions testing students’ knowledge of economics and finance, the IEO includes open-response questions that require students to analyze problems, develop well-reasoned arguments, and apply their knowledge to specific economic scenarios.
For students who are just beginning to explore economics, the Economics Olympiad (EO) can be a strong starting point, as it does not require prior formal training in economics. Students who already have a solid foundation in economics and are looking to challenge themselves in a highly selective international competition may be better suited to the International Economics Olympiad (IEO).
6. Should Students Choose the Economics Olympiad or the International Economics Olympiad?
Choosing the right competition depends on a student’s academic background, strengths, interests, and long-term goals. Rather than focusing solely on which competition is more prestigious or difficult, parents and students should consider which competition provides the right level of challenge and aligns with the student’s current stage of learning.
The Economics Olympiad (EO) May Be a Good Fit If a Student:
- Is just beginning to explore economics
- Wants to build a strong foundation in economics
- Has not previously studied economics in a structured or formal setting
- Wants to gain experience with academic competitions in economics
- Enjoys exploring how economic issues affect everyday life
- Wants to develop economic literacy and analytical thinking
- Is interested in experiencing an international competition environment
In particular, EO can be a good starting point for students who are curious about economics but are not yet sure whether they want to pursue it academically. The competition provides an opportunity to explore the subject, build foundational knowledge, and gain experience with economics-focused academic competitions.
The International Economics Olympiad (IEO) May Be a Good Fit If a Student:
- Already has a solid foundation in economics
- Is considering a future in economics, finance, business, or related fields
- Wants to study economics at a more advanced level
- Enjoys solving problems that require reasoning and explanation, rather than simply selecting an answer
- Is comfortable with data analysis and applying economic models
- Is interested in analyzing real-world business cases
- Wants to compete for the opportunity to become a member of their national team representing their country at the IEO
7. Should Students Participate in Both Competitions?
Students can absolutely participate in both competitions if their schedules and academic goals allow. The Economics Olympiad and International Economics Olympiad do not necessarily have to be viewed as mutually exclusive choices.
Both the Economics Olympiad (EO) and International Economics Olympiad (IEO) can provide valuable academic experiences for students interested in economics. However, because the competitions differ in their subject content, competition formats, and assessment methods, parents and students should take the time to understand the requirements of each competition before deciding which one to pursue.
