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
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 ...
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.
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 ...
where ε p is the (uncompensated) price elasticity, ε p h is the compensated price elasticity, ε w,i the income elasticity of good i, and b j the budget share of good j. Overall, the Slutsky equation states that the total change in demand consists of an income effect and a substitution effect, and both effects must collectively equal the ...
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 Change in Price of Good Y The cross-price elasticity may be positive or negative, depending on whether the goods are complements or substitutes. A substitute good is a good with a positive ...

Elasticity of substitution is the ratio of percentage change in capital-labour ratio with the percentage change in Marginal Rate of Technical Substitution. [1] In a competitive market, it measures the percentage change in the two inputs used in response to a percentage change in their prices. [2]
