Supply & Demand Interactive Model

AQA / Edexcel A-Level Economics

Supply and demand analysis is the foundation of A-Level Economics. This interactive model lets you shift supply and demand curves to explore how changes in determinants (income, costs, tastes, technology, government policy) affect equilibrium price and quantity. Visualise consumer and producer surplus, market disequilibrium (shortage and surplus), and the effects of indirect taxes, subsidies, price floors, and price ceilings. Aligned to AQA (Section 1) and Edexcel (Theme 1) microeconomics specifications.

Frequently asked questions

What causes a shift in the demand curve?+

A shift in the demand curve is caused by a change in a non-price determinant of demand: consumer income, tastes and preferences, the price of substitutes or complements, population size, advertising, or expectations of future prices. A movement along the curve is caused by a change in the good's own price.

What is market equilibrium?+

Market equilibrium occurs where the quantity demanded equals the quantity supplied at a particular price. At this point there is no tendency for the price to change — the market clears with no surplus or shortage.
