【題目】 Assume that we have a demand curve of the form.log(Q)=a-b×log(P)+c×log(I), where Q=quantity, P=price, I=income, and a, b, and c are positive constants. The income and price elasticities for the demand curve represented above are always equal to zero. equal to one. equal(i.e., income elasticity always equals price elasticity). constant.
