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 →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 →GraphExplore the trade-off between producing two goods with limited resources. See efficient, inefficient, and unattainable production points.
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.
