  • Cross Price Elasticity of Demand
    A measure showing how the quantity demanded of one item responds to a price change in another item, revealing their relationship.
  • Substitutes
    Items for which a price increase in one leads to a demand increase in the other, indicated by a positive cross price elasticity.
  • Complements
    Items where a price rise in one causes a demand drop in the other, reflected by a negative cross price elasticity.
  • Unrelated Goods
    Items whose price changes have no effect on each other's demand, resulting in a cross price elasticity of zero.
  • Midpoint Method
    A calculation technique using averages to find percentage changes, reducing bias from direction of change.
  • Numerator
    The top part of the elasticity formula, always representing the quantity demanded change.
  • Denominator
    The bottom part of the elasticity formula, representing the price change of the related good.
  • Percentage Change
    A value showing how much a variable increases or decreases relative to its average, used in elasticity calculations.
  • Quantity Demanded
    The amount of a product consumers are willing to buy at a given price, central to elasticity analysis.
  • Price
    The amount paid for a good, whose changes can influence the demand for another good in cross elasticity.
  • Elasticity Calculation
    A process involving percentage changes in quantity and price to determine responsiveness between goods.
  • Positive Value
    An outcome in cross price elasticity indicating the goods are substitutes.
  • Negative Value
    An outcome in cross price elasticity indicating the goods are complements.
