  • Income Elasticity of Demand
    Measures how quantity demanded changes in response to variations in consumer income, distinguishing between types of goods.
  • Normal Good
    A product for which demand rises as consumer income increases, indicated by a positive value in elasticity calculations.
  • Inferior Good
    A product for which demand falls as consumer income increases, shown by a negative value in elasticity calculations.
  • Luxury Good
    A product with income elasticity greater than one, where demand increases more than proportionally with income.
  • Necessity
    A product with positive income elasticity less than one, where demand increases but less than proportionally with income.
  • Midpoint Method
    A calculation technique using averages to determine percentage changes, minimizing bias from direction of change.
  • Quantity Demanded
    The amount of a product consumers are willing to purchase at a given income level, used in elasticity calculations.
  • Consumer Income
    The financial resources available to buyers, serving as the denominator in income elasticity calculations.
  • Elasticity
    A measure of responsiveness, indicating how much one variable changes in relation to another, such as demand to income.
  • Ceteris Paribus
    The principle of holding all other factors constant to isolate the effect of income changes on demand.
  • Percentage Change
    A calculation expressing the relative difference between two values, used in both numerator and denominator of elasticity.
  • Positive Value
    An outcome in elasticity analysis indicating that demand increases with rising income, associated with normal goods.
  • Negative Value
    An outcome in elasticity analysis indicating that demand decreases as income rises, associated with inferior goods.
