12 unique simulations12 lessons1 sources
Every simulation here runs the real model — the applets a teacher would put on the board, from GeoGebra, not a video of one. Pick a topic, open a card inside its lesson to run it next to the notes, or jump straight to the source. A simulation that fits several lessons is listed under each of them (20 cards in all).

1 · Introduction to economics
- GeoGebraIn the lesson
Production possibility frontier
Drag point E inside, onto and along the curve to see waste, efficiency and opportunity cost; the Productionfrontier slider shows growth.
- GeoGebraIB 1.1
PPC with constant opportunity cost
A straight-line PPC for Item X and Item Y with three labelled points: Efficiency on the line, Recession (inefficiency) inside, Not Possible (yet) beyond.
2 · Microeconomics
2.1Demand and the law of demand
1 sim- GeoGebraIB 2.1
Supply and demand: shifts and surpluses
Demand and supply lines with DemandShift and SupplyShift sliders and tick boxes for shortage, surplus, revenue and consumer and producer surplus.
2.2Supply and the law of supply
1 sim- GeoGebraIB 2.2
Supply and demand: shifts and surpluses
Demand and supply lines with DemandShift and SupplyShift sliders and tick boxes for shortage, surplus, revenue and consumer and producer surplus.
- GeoGebraIn the lesson
Supply and demand: shifts and surpluses
Shift either curve with the sliders and watch ME move; tick Show Shortage and Show Surplus for disequilibrium, then the two surplus boxes.
- GeoGebraIB 2.3
Consumer and producer surplus
Demand and Supply lines with a movable Price line. Consumer and producer surplus are shaded with their values and Total Surplus is shown.
- GeoGebraIn the lesson
Monopoly: profit maximisation
Drag the Quantity slider: read AC, MC, MR and profit. Profit peaks where MC equals MR, and the price is read off D=AR.
- GeoGebraIB 2.10
Price taker: profit maximisation
A price-taking firm: a horizontal price line P with MC and AC curves, Price and Quantity sliders and read-outs of AC, MC and total profit.
- GeoGebraIn the lesson
Monopolistic competition
At h = 0 Demand just touches Average Total Cost: long-run normal profit. Move slider h and watch Demand and Marginal Revenue.
3 · Macroeconomics
- GeoGebraIn the lesson
AD–AS model
Drag the blue handles to shift Aggregate Demand, SR Aggregate Supply or Long Run Aggregate Supply and watch PLe and Ye move.
3.3Low unemployment
1 sim- GeoGebraIB 3.3
AD–AS model
Aggregate Demand, SR Aggregate Supply and a vertical Long Run Aggregate Supply with blue handles to drag; PLe, Ye and Y F are marked on the axes.
3.5Economic growth
2 sims- GeoGebraIn the lesson
AD–AS model
Drag Aggregate Demand right to move Ye towards Y F (actual growth), then drag Long Run Aggregate Supply right (potential growth).
- GeoGebraIB 3.5
Production possibility frontier
A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
- GeoGebraIn the lesson
Lorenz curve and Gini coefficient
Drag the green points below the diagonal to bow the Lorenz curve; the table and the GINI Coefficient update as income gets less equal.
- GeoGebraIB 3.6
Marginal and average income tax rates
A step graph of marginal income tax rates (US, 2019). Drag the income point to read Income, Marginal Rate, Effective Rate and the tax paid.
- GeoGebraIn the lesson
AD–AS model
Drag Aggregate Demand right (expansionary) or left (contractionary) and watch the gap between Ye and Y F close or open.
- GeoGebraIB 3.7
Money market
A vertical Money Supply line and a downward-sloping Money Demand line, nominal interest rate against quantity of money, with handles to drag.
- GeoGebraIB 3.7
Crowding out in loanable funds
A loanable funds diagram (real interest rates against quantity) with one slider, ΔG, for extra government borrowing; 'size of crowding out' is marked.
3.8Supply-side policies
2 sims- GeoGebraIn the lesson
AD–AS model
Drag Long Run Aggregate Supply right: full-employment output Y F rises. Then drag SR Aggregate Supply right and watch PLe fall.
- GeoGebraIB 3.8
Production possibility frontier
A curved frontier for goods X and Y with a movable point E, a Productionfrontier slider and two tick boxes that switch the view.
Each simulation stays the property of its source and is credited on the card inside the lesson. Back to the IB Economics SL course →
