Income elastic goods include luxuries like airline travel, movies, restaurant meals and automobiles. As income rises, demand for income inelastic goods/services tends to increase only marginally. Consumer staples like toothpaste and “sin” items like tobacco and alcohol tend to fall into this category.
When the value of income elasticity of demand the income demand curve will be?
A positive income elasticity of demand is associated with normal goods; an increase in income will lead to a rise in demand. If income elasticity of demand of a commodity is less than 1, it is a necessity good. If the elasticity of demand is greater than 1, it is a luxury good or a superior good.
