单选题
Fred Heyach and Gord Murdoll are discussing whether or not competitive
markets use resources efficiently. Heyach says, "Competition must lead to
the efficient allocation of resources. Consumers are willing to pay more for the
goods they want most, so producers of those goods can outbid other producers for
the resources to make them. Murdoll replies, "At any one point in time the
market might allocate resources efficiently given consumers' preferences, but as
consumers change their minds about which goods they want, the allocation of
resources becomes inefficient. " Are these statements correct or
incorrect?
Heyach
Murdoll
①A. Correct
Incorrect
②B. Incorrect
Correct
③C. Incorrect
Incorrect
【正确答案】
A
【答案解析】Heyach's statement is correct but Murdoll's statement is incorrect. Competitive forces adjust the allocation of resources to changes in consumer preferences. If consumers' demand for a product decreases, the resources that were being used to produce it are diverted to the production of other goods that are in greater demand.
