Explore the trade-off between producing two goods with limited resources. See efficient, inefficient, and unattainable production points.
Explore other economics graphs and simulations.
Interactive Phillips Curve showing the inverse relationship between unemployment and inflation. Adjust parameters to see short-run and long-run dynamics.
Open tool →GraphAggregate Supply and Aggregate Demand diagram. Shift curves to see equilibrium changes in price level and real GDP.
Open tool →GraphClassic supply and demand diagram with adjustable elasticity, intercepts, and equilibrium point.
Open tool →GraphVisualise how tax revenue changes with tax rate. Explore the trade-off between tax rate and economic activity, and find the revenue-maximising rate.
Open tool →GraphVisualise consumer and producer surplus on a supply and demand diagram. Adjust curves and see how surplus areas change at equilibrium.
Open tool →GraphFind the output level where a business covers all costs. Adjust fixed costs, variable costs, and price to see the break-even point shift.
Open tool →GraphInteractive marginal cost, average total cost, average variable cost, and average fixed cost curves. See how costs change with output.
Open tool →GraphSee how price ceilings and price floors affect markets. Explore the shortages caused by maximum prices and the surpluses created by minimum prices.
Open tool →GraphVisualise how a per-unit tax or subsidy shifts the supply curve, splits the burden between consumers and producers, and creates or removes deadweight loss.
Open tool →GraphExplore market failure from negative externalities. See how social cost (MSC) exceeds private cost (MPC), causing overproduction and deadweight loss.
Open tool →GraphExplore positive externalities where social benefit (MSB) exceeds private benefit (MPB), causing underproduction relative to the social optimum.
Open tool →GraphVisualise profit maximisation under monopoly. See AR, MR, MC, and ATC curves, the profit rectangle, and the deadweight loss compared to perfect competition.
Open tool →GraphVisualise income inequality with the Lorenz curve. Adjust the Gini coefficient to see how the distribution diverges from the line of perfect equality.
Open tool →GraphModel the market for money: a vertical money supply and downward-sloping money demand curve determine the equilibrium interest rate.
Open tool →GraphExplore how exchange rates are determined by supply and demand for a currency. Shift curves to see currency depreciation and appreciation.
Open tool →GraphThe aggregate expenditure model: the 45° income-expenditure line, the AE curve, and the multiplier effect of changes in government spending.
