International Economics Olympiad Participants Hold an Open Online Competition

International Economics Olympiad Participants Hold an Open Online Competition

The IEOx Winter Challenge, a two-week international online competition for junior and senior high school students, organized at the initiative of the International Olympiad in Economics, recently came to a close. Students solved a business case and economic tasks in addition to  participating in a financial literacy game on a special online simulator.

The International Economics Olympiad (IEO) was first held in 2018 at the initiative of HSE University in Moscow, and since then it has been held annually (this year, the host country will be Latvia). IEOx is an association of the competition’s alumni who want to contribute to the development of the Olympiad and help new generations of high school students prove themselves. The Winter Challenge is the IEOx’s main project.

581 people registered for the IEOx Winter Challenge, and 366 high schoolers from 21 countries, including Poland, Hungary, Ghana, Thailand, and Jamaica, participated. In contrast to the Olympiad, the IEOx Winter Challenge was open to anyone who wanted to participate, not just the winners of the qualifying national competitions. Therefore, students from countries that are not represented in the official standings could also compete at the international level.

Like the International Economics Olympiad, the IEOx Winter Challenge consisted of three rounds:

  solution of a business case in teams,

 solving quantitative and qualitative problems in economics,

 a financial literacy game on a special online simulator.

The business case of the IEOx Winter Challenge dealt with fundraising for the intellectual Olympiad. The participants were asked to develop a strategy for raising funds for an international competition. The top 6 teams that solved the business case best of all included two teams from Russia.

The uniqueness of the IEOx Winter Challenge project lies in the fact that it was entirely created and carried out by the efforts of former IEO participants and partners. They drew up tasks for the economic part, wrote regulations, came up with a design, drew animations, created a website, and actively participated in attracting high schoolers.

It is equally important that the competition was partly conducted by the students themselves. At the first stage of the tournament, i.e., the solving the business case, peer grading was used, which involves summing up the results of the competition and identifying the best work through peer evaluation. The teams evaluated each other themselves and had the opportunity not only to examine the solutions, but also, by comparing them, to select a winner from among their peers. This allowed them to learn from their mistakes, interact more closely with each other, feel like a part of the process, and gain new experience—not to mention try on the role of an examiner. In the final round of the business case tournament, the international jury (it included 11 people from 8 countries, consulting professionals) practically agreed with the results of the Peer-Grading round.

In addition to the competitions, participants could attend popular science lectures. Talks were given by Professor John Nye (George Mason University, USA) and Gerhard Toews (NES), and psychophysiologist Polina Krivykh delivered a TEDx talk. To help the participants better prepare for solving the business case, workshops were held on strategic consulting and the creation of effective presentations.

The overall winner in the individual standings was Zulfandi Yahya from Indonesia. Russian students Sofya Pirogova, Alina Timoshkina, Mikhail Galkin, and Margarita Shevtsova were also awarded gold medals. Daniyar Sharibayev (Kazakhstan) was named the best in the round of financial literacy, while Jēkabs Gritāns (Latvia) won the round of economic problem solving. First place in the business case tournament went to a team from Latvia.

I am impressed by the number and level of preparation of the Winter Challenge participants. Many of them managed not only to prove themselves, but also to get to know each other: even in the group chat there was networking, support, and excitement! All presentations of business case solutions were very elaborate, and it was very difficult for the jury to make a choice between them. I would advise all students to participate in such projects if they have the opportunity.

Economists Propose More Effective Approach to Reducing Smoking

Economists at HSE University have examined how smokers respond to changes in cigarette prices. When tobacco prices increase, cigarette consumption does not always decline. In fact, spending on tobacco may even rise: according to the researchers, a 1% decrease in cigarette affordability leads to a 0.28% increase in per capita tobacco expenditure. The findings suggest that to reduce smoking rates, tobacco prices must rise faster than household incomes. The study has been published in Voprosy Statistiki.

HSE Economists Use Search Queries to Forecast Birth Rates

Researchers from the HSE Faculty of Economic Sciences have shown that the accuracy of birth rate forecasts for Russia can be improved by almost 50% by incorporating the dynamics of online search queries related to pregnancy and childbirth into forecasting models. In the best-performing models, the forecasting error fell from 4.6% to 3.2%. The findings have been published in Populations and Economics.

Korean Poetry Comes Alive at HSE University Contest

On June 10, 2026, the HSE University–Kyung Hee University Double Degree Programme hosted a Korean Poetry Recitation Contest. Despite the demanding schedule of preparation for the summer examination session, participants went beyond simply memorising poems in Korean, creating original performances complete with presentations and musical accompaniment. The contest brought together students from HSE University and several other higher education institutions.

When Circumstances Are Stronger Than Habits: How Financial Stress Affects Smoking Cessation

HSE researchers have found that the likelihood of quitting smoking rises with increasing financial struggles. While low levels of financial difficulties do not affect smoking behaviour, moderate financial stress can increase the probability of quitting by 13% to 21%. Responses to high financial stress differ by gender: men are almost 1.5 times more likely to give up cigarettes than under normal conditions, whereas no significant effect is observed on women’s decisions to quit smoking. These conclusions are based on data from the Russia Longitudinal Monitoring Survey (RLMS-HSE) for 2000–2023 and have been published in Monitoring of Public Opinion: Economic and Social Changes

‘Sometimes a Student’s Question Will Spark a New Angle on a Problem I’ve Been Working on’

He holds a Master’s and a PhD in Economics and his research interests include political economy, cultural economics, and applied economics. In this interview, Nicolas talks about the qualities that make HSE students exceptional, the overlap between organisational psychology and his research, and why Moscow strikes the ideal work–life balance.

AI Overestimates How Smart People Are, According to HSE Economists

Scientists at HSE University have found that current AI models, including ChatGPT and Claude, tend to overestimate the rationality of their human opponents—whether first-year undergraduate students or experienced scientists—in strategic thinking games, such as the Keynesian beauty contest. While these models attempt to predict human behaviour, they often end up playing 'too smart' and losing because they assume a higher level of logic in people than is actually present. The study has been published in the Journal of Economic Behavior & Organization.

Banking Crises Drive Biodiversity Loss

Economists from HSE University, MGIMO University, and Bocconi University have found that financial crises have a significant negative impact on biodiversity and the environment. This relationship appears to be bi-directional: as global biodiversity declines, the likelihood of new crises increases. The study examines the status of populations encompassing thousands of species worldwide over the past 50 years. The article has been published in Economics Letters, an international journal.
