E) average products are usually less than marginal products.

Question

Quizplus · Accepted Answer

A downward sloping isoquant indicates that as more of one input (such as labor) is added, less of another input (such as capital) is needed to produce the same level of output. This means that marginal product of the input being decreased is eventually decreasing, which is represented through the downward slope of the isoquant. Therefore, choice C is the best answer.
