What is cross elasticity of demand ?
The cross elasticity of demand, also known as the cross-price elasticity of demand, is a measure in economics that compares the percentage change in the quantity desired for one commodity to the percentage change in the price of another good, everything else being equal. In practice, the amount desired of a thing is affected not only by its own price (price elasticity of demand), but also by the prices of other "related" products.
The term is used to describe the relationship between two items, which can be:
Complements
Substitutes \sUnrelated
A negative cross elasticity indicates that two products are complementary, whereas a positive cross elasticity indicates that two products are substitutes.
