Question

Suppose the marginal cost curve in the short run first decreases, then reaches a minimum, and then increases. If we are at an output where marginal cost is increasing, then: Question 5 options: a) marginal product must be increasing. b) marginal product must be decreasing. c) average total cost must be increasing. d) average variable cost must be increasing.

Answer 1

b) Marginal product must be decreasing.

Step-by-step explanation:

b) Marginal product must be decreasing.

The relationship between the marginal product and the marginal cost is negative which means if the marginal cost increases then the marginal product must fall. If the marginal cost decreases then the marginal product must increase. Therefore, option "b" that states marginal product decreases is the correct answer.
