Urban Economics 8
Consider a household with income of $100 and housing consumption equal to 40 units of quality. The income elasticity of demand for housing is 0.75. a . Use a graph like the one shown in Figure 144 to show the households initial utility-maximizing choice (labeled i ). b. Suppose the households income
