  2. Cross elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Cross_elasticity_of_demand

    Cross elasticity of demand of product B with respect to product A (η BA): = / / = > implies two goods are substitutes.Consumers purchase more B when the price of A increases. Example: the cross elasticity of demand of butter with respect to margarine is 0.81, so 1% increase in the price of margarine will increase the demand for butter by 0.81

  3. Price elasticity of demand - Wikipedia

    en.wikipedia.org/wiki/Price_elasticity_of_demand

    When the price elasticity of demand is unit (or unitary) elastic (E d = −1), the percentage change in quantity demanded is equal to that in price, so a change in price will not affect total revenue. When the price elasticity of demand is relatively elastic (−∞ < E d < −1), the percentage change in quantity demanded is greater than that ...

  4. Elasticity (economics) - Wikipedia

    en.wikipedia.org/wiki/Elasticity_(economics)

    Formula for cross-price elasticity. Cross-price elasticity of demand (or cross elasticity of demand) measures the sensitivity between the quantity demanded in one good when there is a change in the price of another good. [17] As a common elasticity, it follows a similar formula to price elasticity of demand.

  5. Substitute good - Wikipedia

    en.wikipedia.org/wiki/Substitute_good

    The cross-price elasticity of demand shows the relationship between two goods, it captures the responsiveness of the quantity demanded of one good to a change in price of another good. [5] Cross-Price Elasticity of Demand (E x,y) is calculated with the following formula: E x,y = Percentage Change in Quantity Demanded for Good X / Percentage ...

  6. Independent goods - Wikipedia

    en.wikipedia.org/wiki/Independent_goods

    Independent goods are goods that have a zero cross elasticity of demand. Changes in the price of one good will have no effect on the demand for an independent good. Thus independent goods are neither complements nor substitutes. For example, a person's demand for nails is usually independent of his or her demand for bread, since they are two ...

    Mathematically speaking, what is important is the own-price elasticity of the good in question, not its cross-price elasticity relative to any other product. Cross-price elasticities can help determine what products are substitutes (high, positive cross-price elasticities) in succeeding iterations of the SSNIP test, but the attractiveness of ...

  9. Law of demand - Wikipedia

    en.wikipedia.org/wiki/Law_of_demand

    The cross elasticity of demand is an economic concept that measures the relative change in demand of a good when another good varies in price. The formula to solve for the coefficient of cross elasticity of demand is calculated by dividing the percentage change in quantity demanded of good A by the percentage change in price of good B.
