Why does consumer surplus exist

The extra benefit that both consumers and suppliers get in the transaction is referred to as the economic surplus. On a supply and demand diagram, consumer surplus is the area usually a triangular area above the equilibrium price of the good and below the demand curve. The point at which a price stabilizes—so that both consumers and producers receive maximum surplus in an economy—is known as the market equilibrium.

This area reflects the assumption that consumers would be willing to buy a single unit of the good at a price higher than the equilibrium price, plus a second additional unit at a price below that but still above the equilibrium price.

However, what they actually end up paying is just the equilibrium price for each unit they buy. Likewise, in the same supply and demand diagram, the producer surplus is the area below the equilibrium price but above the supply curve. This reflects the assumption that producers would have been willing to supply the first unit at a price lower than the equilibrium price, and an additional second unit at a price above that while still below the equilibrium price.

However, in the market economy, producers receive the equilibrium price for all the units they sell. Alfred Marshall. Palgrave, Macmillan, Your Privacy Rights.
