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).

How does the price range affect the elasticity of demand for a product? Demand for a good can be inelastic at a low price, but elastic at a high price If prices rise, but income stays the same, what is the effect on the quantity demanded? The quantity of demand decreases What effect does the availability of many substitutes have on the elasticity of demand for a good? Demand is elastic If prices rise, but income stays the same, what is the effect on demand?
