Which of the following demonstrates marginal thinking?

Question

Quizplus · Accepted Answer

Marginal thinking involves making decisions at the margin by weighing the costs and benefits of incremental changes. Option B involves deciding to spend one more hour studying economics based on the expected improvement in the test, which is an example of marginal thinking. Option C involves attending a Sociology class that is usually skipped, given the presence of a guest lecturer that the student is interested in hearing. This decision is also an example of marginal thinking as the benefit of attending the class outweighs the cost of attending a class that is usually skipped. Hence, both options B and C are examples of marginal thinking. Option A, on the other hand, is a major decision that involves giving up an entire category of food and does not involve thinking at the margin.
