The International Trade Game ยท Digital Edition

Your classroom is now 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, with no scissors, paper or glue to buy, and a full instructor console, scenario packs, analytics and debrief toolkit built in.

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

Why instructors choose it

Everything the paper game teaches. Everything paper can't do.

Built on John Sloman's classic classroom design and the patterns of leading teaching platforms: join codes, instructor controls, live dashboards and ready-made debriefs.

๐ŸŒ

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.

๐Ÿญ

Hands-on production

Teams manufacture goods through a fast quality-control mini-game. Defects waste materials, standards tighten mid-game, and every country's output speed differs, making opportunity cost something students feel.

๐Ÿ“ˆ

A living world market

Posted prices move with scripted supply and demand shocks, announced on a projected newswire. Export contracts pay premiums for planned production, and the World Bank offers tools and loans at painful rates.

๐Ÿค

Real negotiation

Trades happen face to face and are recorded in each nation's ledger. Cartels, alliances, broken promises, tariffs and sanctions all become debrief gold.

๐ŸŽ›๏ธ

Instructor console

Master timer with pause and extend, price board, read-aloud newswire, auction toolkit, custom announcements, leaderboard with podium reveal, and copy-out results for your gradebook.

๐ŸŽ“

Theory built in

A three-stage debrief and an in-app Academy covering absolute and comparative advantage, factor endowments, terms of trade and trade policy, including an interactive comparative advantage 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

Twenty minutes of production, deals and price shocks. Collect GDP figures, reveal the podium, then run the guided three-stage debrief.

Scenario packs

One game. Three economies to teach with.

Core

๐Ÿงญ Classic Trade Routes

The faithful digital adaptation: unequal endowments, a triangle glut, a circle boom, an innovation summit and a closing rally. The cleanest route to comparative advantage and gains from trade.

Markets

๐ŸŽข Volatile Markets

Commodity-cycle chaos: spikes, crashes, a recovery boom and a late flash dip. Teaches diversification, market timing and why terms of trade shift, ideal for second plays.

Policy

๐Ÿ›๏ธ Policy Lab

An autarky opening, a customs-duty window, an export subsidy, sanctions on a major power and a closing trade accord. Institutions, protectionism and the WTO come alive.

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.

๐ŸŒ

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.

๐Ÿงฎ

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 UKโ€“Japan and Bel Canto examples.

๐ŸŽ“

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.

๐Ÿ“

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.

Pricing

Simple licensing for classrooms.

Access codes unlock the full simulation. Buy once per class or license your whole department. Prices shown are launch placeholders and can be updated by the owner in the configuration block.

About the creator

Dr Abubakar Hassan

Lecturer in Economics ยท 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.

FAQ

Common questions.

Do students need accounts or installs?

No. Teams open a link in any modern browser on a laptop, tablet or phone. The whole simulation runs client-side and keeps working even if the wifi drops mid-game.

How do devices stay in sync without a server?

All market events run on a shared deterministic schedule. Teams start together on the instructor's countdown, and every announcement is also read aloud from the projected newswire, exactly as a facilitator would in the paper game.

How many students does it support?

Two to eight nations per game, with two to ten students per nation. For larger cohorts, run parallel games in separate rooms, as with the original classroom design.

What does it teach?

Scarcity, specialisation, absolute and comparative advantage, factor endowments, terms of trade, gains from trade, market volatility, negotiation and market power, and the role of institutions and trade policy.

Can I customise it?

Yes. Game length, scenario, autarky opening and team composition are configurable per session, and the owner can edit prices, access codes and branding directly in the file's configuration block.

๐ŸŽฏ Purpose of the game

The International Trade Game is an experiential learning activity: nations with deliberately unequal resources must produce, negotiate and sell in a live world market. It turns abstract theory into a hands-on, competitive exercise, so that specialisation, opportunity cost and comparative advantage are discovered rather than recited.

๐Ÿ“ˆ 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.

๐ŸŒ Trade Simulation

Live multiplayer. Eight nations, five goods, three scenarios.

๐Ÿ”จ National Auction

Bid for national priorities. Scarcity, choice and opportunity cost.

๐Ÿงฎ Advantage Lab

The Absolute & Comparative Advantage Simulator, built interactively.

๐ŸŽ“ Trade Theory

Eight sourced lessons and a live CA calculator.

๐Ÿ“ Test Simulator

Randomised exam practice with worked explanations.

Strategy playbook

How to maximise your gains

Winning is not about producing the most goods. It is about producing the right goods and pricing your scarcity well. These tips are drawn from trade theory and from what actually decides the leaderboard.

Coach

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.

Waiting for the opening bell

Read your country card below. When the instructor counts down 3-2-1-TRADE, press start. All teams start together so market events hit everyone at once.

๐Ÿ“ฆ Warehouse โ€” unsold goods are worthless at the close

๐Ÿ“œ Export contracts

Buyers pay a premium over spot for planned bundles. Each contract can be fulfilled once by your nation, straight from your warehouse.

Sell to the world market

๐Ÿฆ World Bank

Closed until the Technology Expo. Premium prices; a last resort, never a strategy.

Record a deal

Negotiate face to face, agree terms, then both teams record their own side. Instructors can audit the ledgers. Broken promises are legal โ€” and remembered.

๐Ÿ“’ National ledger

    Rules in brief

    • Goal: the highest GDP (cash) when markets close.
    • Goods need tools (kept) and paper (consumed). Production runs a quality check: tap the rivets in order; three misses or a timeout scraps the batch.
    • Your productivity table shows seconds per unit in your nation. Compare with rivals to find your comparative advantage.
    • Trade anything โ€” paper, tools, tech marks, cash โ€” at any negotiated price, once borders are open.
    • ๐Ÿ… A Tech Mark attached at sale triples that unit's price.
    • Watch the newswire: shocks, duties and contracts move the market for everyone.
    • Unsold stock is worthless at the close. Time your sales.

      Teams read their result screens aloud. Type team name and GDP, then reveal.

      Debrief โ€” 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 ยท What just happened?

      Feelings and comparisons โ€” 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 โ€” 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 ยท Is the world really like this?

      Realism โ€” 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 ยท The theory in one line each

      Consolidation โ€” 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?

      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:

      ๐Ÿ“Š Output & opportunity cost

      ๐Ÿงญ Production possibilities

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

      โš–๏ธ Autarky vs specialisation & trade

      ๐Ÿ’ท Long run: does wage follow productivity?

      Short-run comparative advantage depends only on productivity. In the long run, unit labour cost (wage รท 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 ยท National Auction

      You lead your country.
      You cannot afford everything.

      Governments bid live against one another for the national priorities that matter most. Every dollar spent on one priority is a dollar not spent on another. Win the lots you value, then defend what you gave up. Points, not spending, decide the winner.

      Solo mode

      ๐ŸŽฏ The group task

      1. Work as a team to bid on your top priorities.
      2. Be ready to answer: "What are you giving up by choosing these?" That is your opportunity cost.
      3. Each lot carries bonus points. The best portfolio and the sharpest justification wins.

      ๐Ÿ”จ How the live bidding works

      1. One lot opens at a time with a guide price and a reserve.
      2. Teams raise by any amount: tap a paddle, press keys 1โ€“8, or type any figure.
      3. Every raise is announced, and the outbid team is named.
      4. When no one raises, the gavel counts down: going once, going twice, SOLD.

      Countries

      Rename each group. Keys 1โ€“8 are their paddle shortcuts.
