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.
(I/Q)

【題目】 A profit-maximizing firm in a competitive market is able to sell its product for $7. At its current level of output, the firm’s average total cost is $10. The firm’s marginal cost curve crosses its marginal revenue curve at an output level of 9 units. The firm experiences a
loss of exactly $27.

【題目】 When demand increases and supply decreases, the
equilibrium price rises, and the equilibrium quantity might increase, decrease, or remain constant.
【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
constant.
equal to zero.
equal to one.
equal(i.e., income elasticity always equals price elasticity).
答案 constant
