每日答題： 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. 答案： c(I／Q)
Suppose A, B and C are three points on a linear demand as in the figure below. The comparison of price elasticities is A B C. A B C. A B and B C. A = B = C.

【題目】 In the short run the magnitude of the own price elasticity of demand for ice cream: is lower than in the long run. is the same as in the long run. is higher than in the long run. does not depend on the fact that ice cream can be frozen.
【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.
【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)
【題目】 The kinked demand curve model assumes that a firm's rivals will follow the firm's price decreases but not its price increases. follow the firm's price increases but not its price decreases. follow any price change the firm makes. not follow any of the firm's price changes.
【題目】 Which of the following factors would not cause the demand curve for a given product to shift? Changes in price. Changes in the price of a related good. Changes in income. Changes in the distribution of income.
【題目】 The demand for a product tends to be inelastic if. a small proportion of consumer's income is spent on the good. consumers are quick to respond to price changes. it is a normal good. it is expensive.
【題目】 Suppose the demand for gourmet coffee can be represented by a linear demand curve. When income rises cause the demand curve for gourmet coffee shift to the right parallelly: becomes more elastic at the price that prevailed before the change in income becomes less elastic at the price that prevailed before the change in income becomes more elastic at every price becomes less elastic at every price
【題目】 When demand increases and supply decreases, the equilibrium price falls, and the equilibrium quantity might increase, decrease, or remain constant. equilibrium price rises, and the equilibrium quantity might increase, decrease, or remain constant. equilibrium quantity decreases, and the equilibrium price might rise, fall, or remain constant. equilibrium quantity increases, and the equilibrium price might rise, fall, or remain constant.
