  • Demand schedule: (p. 92) A table showing the quantity demanded of a product at different prices.
  • Demand curve: (p. 93) A graph illustrating the relationship between the price of a product and the quantity demanded. It is downward-sloping.
  • Law of Demand: (p. 93) The concept that the quantity demanded of a good or service varies inversely with its price (other factors constant).
  • Market demand curve: (p. 94) The sum of all individual demand curves in a market.
  • Marginal utility: (p. 95) The extra satisfaction a consumer gains from consuming one more unit of a good or service.

Main Idea

  • Demand is a concept that specifies the various quantities of a product that will be bought at differing prices (in certain conditions).

Economics & You

  • Consumers generally buy more of something when its price is lower and less when its price is higher.

Demand illustrated

  • The demand concept is easy to understand as it only involves two variables: Price and quantity of a product.

Demand schedule and Demand curve

  • The demand schedule and demand curve show the quantity of a good/service demanded at every possible price.
  • A demand curve shows the quantity demanded at each price.

The Individual Demand Curve

  • The demand schedule in one section of a figure can be presented graphically as a downward-sloping line in another section.
  • The points on the schedule are transferred to the graph and connected to create the curve.
  • The curve reflects the quantity demanded at every possible price.
  • Example usage: point ‘a’ on the graph means three CDs were purchased at $15 each.

The Assumptions Of The Law Of Demand

  • Price of related goods remains constant.
  • Income of the consumer remains constant.
  • Taste and preferences of the consumer remain constant.
