Meaning and Characteristics of Demand

  • Demand is not just desire; it requires willingness and ability to pay for a good or service.
  • Three essential characteristics of demand: desire, purchasing power, and willingness to spend.
  • Example: A poor person may desire a car but cannot afford it — this is not demand. A rich person who buys a car shows demand.

Demand Function and Determinants of Demand

  • The demand function shows how quantity demanded depends on various factors.
  • Main determinants: own price, prices of related goods, income, tastes and preferences, population, technology, and weather.
