It is calculated as percentage change in quantity demanded for one good divided by percentage change in price of another good. It explains the nature and degree of relationship between price of one good and the demand of another good i.e. whether the goods are substitutes, complements or independent. It is explained by three different degrees or possibilities as below: 1.       Positive Cross price elasticity of demand ( competing demand or substitutes) 2.       Negative Cross price elasticity of demand ( Joint demand or complements) 3.       Zero Cross price elasticity of demand (Absence of demand relationship) 1. Positive Cross price elasticity of demand Positive cross price elasticity implies that a rise in deman
