In economics, the cross (or cross-price) elasticity of demand (XED) measures the effect of changes in the price of one good on the quantity demanded of another good. This reflects the fact that the quantity demanded of good is dependent on not only its own price (price elasticity of demand) but also the price of other "related" good.
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 ...
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 ...
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.
The Cross elasticity of demand, also commonly referred to as the Cross-price elasticity of demand, allows companies to establish competitive prices against substitute goods and complementary goods. The metric figure produced by the equation thus determines the strength of both the relationship and competition between the two goods. [15]

But the food price inflation that stunned the U.S. — and other parts of the world — in 2021 and 2022 had complicated causes that are difficult to unwind, from the pandemic to the Ukraine war ...
Complementary goods exhibit a negative cross elasticity of demand: as the price of goods Y rises, the demand for good X falls. In economics, a complementary good is a good whose appeal increases with the popularity of its complement.
