Suppose average real incomes go up by 10% in one year. During that year suppose that: purchases at dollar stores decline by 2%, purchases of dishwashing liquid soap increase by 2%, and purchases of new automobiles increase by 12%. Using the terminology of income elasticity of demand, discuss which of these is likely an inferior good, normal good, or even closer to a luxury good.
