Buyers expect the price of concert tickets to be higher next month. Before the concert month arrives, today’s demand curve will tend to:
A. Shift left, because a future rise always reduces current demand.
B. Stay unchanged until the future price actually changes.
C. Shift right, as some purchases are brought forward.✓ 答案
D. Shift by the same amount as supply, so price cannot change today.
解說
Expected future price is a demand determinant. If buyers think tickets will cost more later, some buy now, so current demand shifts right. You do not wait for the future price to appear on today’s axis. Supply need not shift with it.
