The International Trade Game · Digital Edition

Turn your classroom into a world economy.

turns the celebrated International Trade Game into a complete digital simulation. Nations with unequal resources manufacture goods, strike deals, ride price shocks and discover comparative advantage for themselves, It requires no scissors, paper or other materials, and it includes an instructor console, scenario packs and a structured debrief.

Runs in any browser · No installs, no student accounts · Works offline once loaded · 2 to 8 teams · Have an access code?

Why instructors choose it

Everything the original game teaches, and more besides.

Built on John Sloman's established classroom design, with join codes, instructor controls, live dashboards and a prepared debrief.

🌍

Eight playable nations

From advanced industrial Nordhaven to resource-rich Terravia, each country card mirrors a real-world archetype with its own capital stock, raw materials and productivity table, so factor endowments and Heckscher-Ohlin logic are baked into play.

🏭

Hands-on production

Teams manufacture goods through a fast quality-control mini-game. Defective units waste materials, standards tighten during the game, and each country produces at a different speed, so opportunity cost becomes directly observable.

📈

A living world market

Posted prices move in response to scheduled supply and demand shocks, which are announced on a projected newswire. Export contracts pay a premium for planned production, and the World Bank supplies tools and loans at a high cost.

🤝

Real negotiation

Trades are negotiated face to face and recorded in each nation's ledger. Cartels, alliances, broken agreements, tariffs and sanctions all provide material for the debrief.

🎛️

Instructor console

A master timer with pause and extension, a price board, a newswire to read aloud, an auction toolkit, custom announcements, a leaderboard with podium reveal, and results that can be exported to a gradebook.

🎓

Theory built in

A three-stage debrief and a set of lessons covering absolute and comparative advantage, factor endowments, terms of trade and trade policy, with an interactive calculator.

How it works

Running a session takes three steps.

1

Project the console

Open on the big screen as Instructor, pick a scenario and game length, and read the class settings aloud.

2

Teams join on any device

Each team opens the same link on a laptop or phone, enters a team name and takes the nation you assign. Count down together and start.

3

Play, reveal, debrief

Production, negotiation and price shocks proceed for the set period. Collect the final figures, reveal the podium, then run the three-stage debrief.

Scenario packs

One game. Three economies to teach with.

Core

🧭 Classic Trade Routes

A faithful digital adaptation: unequal endowments, an oversupply of triangles, rising demand for circles, an innovation summit and a closing rally. The most direct route to comparative advantage and the gains from trade.

Markets

🎢 Volatile Markets

A volatile commodity cycle: sharp rises, falls, a recovery and a late decline. It illustrates diversification, market timing and shifts in the terms of trade, and suits a second session.

Policy

🏛️ Policy Lab

The session opens in autarky, followed by a customs duty, an export subsidy, sanctions on a major economy and a closing trade accord. It examines institutions, protection and the role of the World Trade Organization.

Four ways to teach with it

One platform, four modes.

The live classroom game is the centrepiece. Around it sit three self-study tools students can open any time, all from this page. Watch the 60-second tour to see each in action.

🌍

The Trade Game (live)

The multiplayer classroom simulation. Teams take nations, produce goods, negotiate deals and ride market shocks across three scenario packs, run from the projected instructor console.

🧮

Advantage Lab

An interactive lab for absolute and comparative advantage. Allocate workers between two goods in two economies and watch opportunity cost, specialisation and the gains from trade emerge, built on the classic UK–Japan and Bel Canto examples.

🎓

Trade Academy

Eight short, sourced lessons from mercantilism to modern trade theory, with a comparative advantage calculator and a full reference list in APA style.

📝

Test Simulator

Exam-style multiple choice drawn at random from a large bank, with worked explanations, topic focus and a grade band, ideal for revision or a quick formative check.

About the creator

Dr Abubakar Hassan

Lecturer in Economics · University of Dundee School of Business

is designed and operated by Dr Abubakar Hassan, Lecturer in Economics at the University of Dundee School of Business, where he teaches international trade, business strategy and quantitative methods, supervises doctoral researchers, and serves as a Senior Adviser of Studies. He holds a PhD in Energy Economics from the Centre for Energy, Petroleum and Mineral Law and Policy.

His work sits at the intersection of applied economics and pedagogy, with a particular interest in experiential learning: how simulation, negotiation and play make abstract theory tangible. distils years of running the International Trade Game with undergraduate and postgraduate cohorts, together with the published scholarship on trade, foreign direct investment and simulation-based teaching, into a platform any instructor can run in a single session.

Frequently asked questions

Common questions, answered in full.

Everything an instructor or a student is likely to ask before a first session.

Do students need accounts or installs?

No. Teams open a single link in any modern browser, on a laptop, tablet or phone, and nothing is installed. The platform can also be added to a phone’s home screen as an app. It runs entirely in the browser and continues to work if the connection drops mid-session.

How are countries assigned to teams?

The instructor may assign nations directly, keeping the assignment concealed from students until the session opens, in the manner of the sealed envelopes used in the original classroom activity, or may allow teams to select their own nation. Both modes are available from the Instructor Console.

How do devices stay synchronised without a central server?

Two mechanisms are available. By default, all scheduled events run on a shared timetable, and every team begins together on the instructor’s countdown. Where live synchronisation is enabled, the instructor’s console additionally becomes the source of truth for the market, and every team device, including live trade proposals between teams, updates automatically and in real time.

How many students does this support?

Two to eight nations per session, with two to ten students collaborating per nation. Larger cohorts are accommodated by running parallel sessions in separate rooms, following the original classroom design, which has been used successfully with cohorts of up to 240 students under a single facilitator.

What does the platform teach?

Scarcity and opportunity cost, absolute and comparative advantage, factor endowments, terms of trade and the gains from trade, market volatility, negotiation and market power, foreign direct investment, and the role of institutions and trade policy. A full account of the underlying theory, with academic citations, is provided in the Trade Theory section.

What happens the first time a student or instructor opens a game?

Each of the three games opens with a short guided walkthrough appropriate to the role of the person viewing it: students are shown how to play, and instructors are shown how to control the session and what to say to the class. These walkthroughs can be revisited at any time from within each game.

Is prior knowledge of economics required?

No. The platform is designed for students encountering these ideas for the first time. Rules are explained before play begins, and the underlying theory is introduced afterwards, during the structured debrief, so that the concepts are discovered through experience rather than assumed in advance.

How much does it cost?

A free demonstration licence is available with no time limit on trying the platform before purchase. Paid licences are priced per class per term, or as an annual departmental licence covering an unlimited number of classes and instructors. Current prices are shown above and may be revised by the licence holder.

How long does a session last?

Sessions may be set from ten minutes to two hours. A single class period of forty-five to sixty minutes, inclusive of debrief, is typical for a first use.

Can the platform be customised?

Yes. Session length, scenario, whether the session opens in autarky, and team assignment are configurable before each session. The licence holder may also edit prices, access codes, branding and colour themes directly within the platform’s configuration.

Where does the International Trade game come from, and is it properly credited?

It is a digital adaptation of the classroom activity originated by the development charity ActionAid, subsequently adapted for economics teaching by John Sloman (2002) and published through the Economics Network. Full attribution, and an explicit account of what is and is not original to this implementation, is provided within the platform’s Origins and Credits page.

What data is collected about students?

None that identifies an individual. No accounts are created and no personal details are requested. Where feedback surveys are used, responses are anonymous by design. Full detail is set out in the Privacy Notice linked from this page.

Does it work on mobile phones?

Yes. The interface adapts to phone, tablet and desktop screens, and the platform can be installed to a phone’s home screen for an app-like experience, including limited offline use.

Can colour and font size be adjusted for accessibility?

Yes. Three colour modes are available, a daylight mode for general use, a darker mode suited to projection, and a high-contrast mode, selectable at any time from the sidebar.

🎯 Purpose of the game

The International Trade Game is an experiential learning activity in which nations with deliberately unequal resources produce, negotiate and sell in a live world market. It converts abstract theory into a practical exercise, so that specialisation, opportunity cost and comparative advantage are discovered by the participants rather than presented to them.

📈 Learning outcomes

  • Experience why nations specialise in goods they produce at the lowest opportunity cost.
  • Observe how trade raises total output and allows consumption beyond the production frontier.
  • Understand negotiation, market power, terms of trade and the role of institutions.

🌍 Trade Simulation

A live multiplayer game with eight nations, five goods and three scenarios.

🔨 National Auction

A live auction for national priorities, illustrating scarcity, choice and opportunity cost.

🧮 Advantage Lab

An interactive exercise in absolute and comparative advantage.

🎓 Trade Theory

Referenced lessons in trade theory, with an interactive calculator.

📝 Test Simulator

Randomised examination practice with worked explanations.

Team setup

Name your team, take your nation

Match the settings your instructor reads out, then select the country you were assigned. Endowments are deliberately unequal: that is the economics.

Team assignment

Claim your team

Your instructor has prepared a sealed national dossier for each team. Claim the team you belong to; its contents remain sealed until your instructor says to open them.

Waiting for the opening bell

Read your country card below. When the instructor gives the signal, select Start. All teams begin together, so that market events affect every nation at the same time.

Warehouse: unsold goods have no value at the close

📜 Export contracts

Buyers pay a premium above the market price for a specified set of goods. Each contract may be fulfilled once by your nation, directly from your warehouse.

Sell to the world market

🏦 World Bank

Closed until the Technology Expo. Premium prices; a last resort rather than a strategy.

Record a deal

Select a common exchange to complete the form, then adjust the figures and confirm. Negotiate directly with the other nation; each team records its own side of the agreement.

📒 National ledger

    Rules in brief

    • Objective: the highest cash holding when the markets close.
    • Each good requires tools, which are retained, and paper, which is consumed. Production includes a quality check: select the points in order. Three errors, or running out of time, results in the batch being rejected.
    • The productivity table shows the seconds required per unit in your nation. Compare it with other nations to identify your comparative advantage.
    • Once the borders are open, any item may be traded (paper, tools, Technology Marks or cash) at any agreed price.
    • A Technology Mark attached at the point of sale triples the price of that unit.
    • Follow the newswire: price shocks, duties and contracts affect all nations.
    • Unsold stock has no value at the close. Time your sales accordingly.

      Debrief — three stages

      Follow the classic structure: first feelings and comparisons, then realism, then theory. Ten to fifteen minutes turns the noise into learning.

      Stage 1 · What just happened?

      Feelings and comparisons — 4 minutes

      How did it feel to play your nation?

      Ask a high-income and a low-income team in turn. Frustration, power and dependency usually surface immediately.

      What did each nation specialise in — and why?

      Using your productivity table, what was your opportunity cost of one Circle in Triangles? Did you specialise where that cost was lowest?

      Compare autarky and open-borders GDP.

      If the autarky opening was on, every result screen shows GDP at the moment borders opened. Who gained most from trade, in absolute and in percentage terms?

      Stage 2 · Is the world really like this?

      Realism — 4 minutes

      What do paper, scissors and compasses stand for?

      Raw materials versus physical and human capital. Which real economies resemble each nation? The country dossiers name archetypes to anchor the discussion.

      Who held market power, and what were the terms of trade?

      What did a pair of scissors cost in sheets of paper at minute five versus minute fifteen? Why did that ratio move?

      Were promises kept?

      Any broken deals or cartels? What would enforceable contracts, a court, or a WTO-style referee have changed?

      Stage 3 · The theory in one line each

      Consolidation — 4 minutes

      Absolute vs comparative advantage.

      A nation can be worse at everything and still gain from trade, if it specialises where its opportunity cost is lowest. Have a student state it, then test it against the session's data.

      Shocks and diversification.

      Which real-world events mirror the glut, the boom and the rally? What protects a one-good economy?

      Winners, losers and policy.

      Trade raised total output, but not everyone equally. What can policy (aid, technology transfer, tariffs, subsidies) do about it, and at what cost?

      Class discussion & feedback

      After the debrief, ask the class to open Feedback & Survey from their sidebar. Responses appear here live, and can be exported as a CSV for your own research or for a teaching-and-learning submission.

      🗣️ Closing class discussion — five prompts

      1. Endowment or strategy? How much of the gap between the top and bottom country was the envelope, and how much was what you did with it?
      2. Would you have traded differently if you had known the price shocks were coming? What does that tell you about information and risk?
      3. Was anyone exploited? Every deal was voluntary. Does that settle the question, or not?
      4. What would you change about the rules of this world to make the outcome fairer, and what would it cost in efficiency?
      5. Where did you see comparative advantage actually operating, as opposed to being talked about?

      Advantage Lab

      Absolute & Comparative Advantage Simulator

      Allocate workers between two goods in two economies and watch opportunity cost, absolute and comparative advantage, and the gains from specialisation emerge. Built around two classic worked examples.

      Preset:

      📊 Output & opportunity cost

      🧭 Production possibilities

      Each nation's frontier, its current point, and the combined economy. Specialisation pushes the world point beyond the summed autarky frontier.

      ⚖️ Autarky vs specialisation & trade

      💷 Long run: does wage follow productivity?

      Short-run comparative advantage depends only on productivity. In the long run, unit labour cost (wage ÷ productivity) decides where production actually locates. Slide the relative wage and watch which plant is cheapest per unit.

      Assessment

      International Trade Test Simulator

      Exam-style practice

      Questions are drawn at random from a bank spanning the theory of trade, opportunity cost, factor endowments, terms of trade and policy. Each attempt is a fresh randomised set, mirroring a Blackboard-style pool. Full worked explanations follow every question.

      Game 2 · National Auction

      You lead your country.
      You cannot afford everything.

      Governments bid against one another for the national priorities they value most. Every sum committed to one priority is a sum not available for another. Secure the lots your government values, then justify what was forgone. The result is decided by points, not by expenditure.

      Solo mode

      🎯 The group task

      1. Agree as a team which priorities your country will bid for.
      2. Be prepared to explain what your country gave up in making those choices. That is the opportunity cost.
      3. Each lot carries a points value. The result depends on both the portfolio secured and the quality of the justification given.

      🔨 How the live bidding works

      1. One lot opens at a time with a guide price and a reserve.
      2. Teams may raise by any amount, using the paddles, the number keys 1 to 8, or by entering a figure directly.
      3. Each bid is announced, and the country that has been outbid is identified.
      4. When no further bid is made, the lot is sold to the highest bidder.

      Countries

      Rename each group as required. The number keys 1 to 8 correspond to the paddles.

      Game settings

      All settings may be changed at any time and take effect immediately.

      Resets on every new bid. When it runs out, nothing sells automatically \u2014 you press SOLD when ready.

      Lots on the block

      Any figure may be edited, and additional lots may be written to suit your syllabus.
