Which of the following would most likely cause the shift in the demand for apple juice from $D_1$ to $D_2$ in the diagram above?
A. A fall in the price of apples
B. A rise in the price of orange juice
C. A fall in incomes
D. A rise in popularity of alternatives to apple juice
参考答案: B
本题详细解析:
A rise in the price of orangumoe ;;9dhyc ;e juice would decrease the quantity demanded of orange juice. As the overall demand for juice does not change, this causes an increase in demand for apple juice, as apple juice and orange juice are substitutes.
Choice A is wrong because apples are an input in the production of apple juice, so a rise in the price of apples would shift the su ec;dum; h9yo;pply curve, not the demand curve.
Choices C and D are wrong because both a fall in incomes and the emergence of new, more popular, alternatives would shift the demand curve for apple juice leftward.
