    Study Notes

    Consumer Surplus

    • Consumer surplus is the difference between the price paid and the maximum price a consumer is willing to pay (reservation price).
    • A consumer's willingness to pay is the highest price they are willing to pay for a good.
    • Total consumer surplus is the sum of individual consumer surpluses for all buyers.
    • Consumer surplus is graphically represented by the area beneath the demand curve and above the price.
    • A lower price increases consumer surplus in two ways:
      • Existing buyers get a larger surplus.
      • New buyers enter the market.

    Producer Surplus

    • Producer surplus is the difference between the market price and the minimum price a producer is willing to accept.
    • A seller's willingness to sell (potential cost) is the lowest price at which they are willing to provide a good.
    • Total producer surplus is the sum of individual producer surpluses for all sellers in the market.
    • Producer surplus is graphically represented by the area above the supply curve and below the price.
    • A higher price increases producer surplus in two ways:
      • Existing sellers get a larger surplus.
      • New sellers enter the market.

    Total Surplus

    • Total surplus is the sum of consumer surplus and producer surplus.
    • It represents the total benefit to society from a transaction.

    Graphical Representation (Note: This refers to a graph; some information is missing from the diagram you provided in the OCR, so the specifics of the graph aren't explicitly stated in the points below):

    • Point E on the graph likely represents the equilibrium point (where supply and demand intersect).
    • The total surplus at point E is the largest possible.
