If the cross price elasticity is positive, then we call such goods Substitutes (example: pizza and burgers -- you usually consume either or). The income elasticity of demand measures the change in the quantity demanded of some good, when the income changes, holding everything else constant.For example you can measure what happens to the demand for expensive red wine when income increases.f the cross price elasticity is positive, then we call such goods Substitutes (example: pizza and burgers -- you usually consume either or).

Coefficient of Elasticity. With an inelastic demand, price increases will grow revenue, while this will happen for price reductions in an elastic demand (Anderson, 2005).. The concept describes the importance of understanding the price elasticity of demand. The concept explains how the quantity demanded of a good or service responds to a change in the price of that good or service and provides case studies of organisations that apply the coefficient of elasticity to perform better.
