【題目】 A simple linear demand function may be stated as Q= a-bP+cI where Q is quantity demanded , P is the product price, and I is consumer income. To compute an appropriate value for c, we can use observed values for Q and I and then set the estimated income elasticity of demand equal to. Q／(cI) c(I／Q) -b(I／Q) c(Q／I)
