Quizplus · Accepted Answer

In an oligopolistic market where prices vary, it is optimal for a consumer to gather information about prices until the expected marginal utility of more information equals the marginal cost of gathering it. This way, the consumer can make a better-informed decision while minimizing the cost of acquiring information. Gathering all available information (choice A) may not be necessary if the effort and time required to gather information outweigh the potential benefits. Gathering information only if it can be gathered without cost (choice C) may not provide enough information to make an informed decision. Ignoring information about prices (choice D) is not optimal as it can lead to suboptimal decisions.
