  • Income Elasticity of Demand
    A measure showing how quantity demanded changes in response to consumer income variations, using income instead of price in calculations.
  • Normal Good
    A product for which demand increases as consumer income rises, indicated by a positive income elasticity value.
  • Inferior Good
    A product for which demand decreases as consumer income rises, reflected by a negative income elasticity value.
  • Luxury Good
    A product with income elasticity greater than 1, meaning demand rises more than proportionally as income increases.
  • Necessity
    A product with income elasticity between 0 and 1, where demand rises 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 good consumers are willing to buy at a given income, holding other factors constant.
  • Ceteris Paribus
    An assumption holding all variables except income constant to isolate its effect on demand.
  • Percentage Change
    A calculation comparing the difference between two values to their average, used in elasticity formulas.
  • Denominator
    The bottom part of the elasticity formula, representing the percentage change in income for this context.
  • Numerator
    The top part of the elasticity formula, representing the percentage change in quantity demanded.
  • Positive Value
    An outcome in elasticity analysis indicating a direct relationship between income and quantity demanded.
  • Negative Value
    An outcome in elasticity analysis indicating an inverse relationship between income and quantity demanded.
  • Demand Curve
    A graphical representation showing the relationship between quantity demanded and income, holding other factors constant.
  • Analysis
    The process of interpreting elasticity results to classify goods as normal, inferior, luxury, or necessity.
