CFA Practice Question
Consider resource A, used by firms in two different industries. In Industry 1, the marginal revenue per unit of output is $2.50 and the marginal productivity of resource A is 0.4. In Industry 2, the marginal revenue per unit produced is $5.00 and the marginal productivity of resource A is 0.25. Which of the following statements is true?
A. The market price for resource A is determined by Industry 2 because of its higher marginal revenue per unit produced.
B. The market price for resource A is determined by the marginal revenue product of resource A in Industry 1.
C. The market price for resource A is determined by the marginal revenue product of resource A in Industry 2.
Explanation: The market price for resource A will be determined by the industry willing to pay the highest price for the resource. Each industry would be willing to pay as much as the marginal revenue product of the resource. The marginal revenue product in Industry 1 is (0.4)($2.50) = $1.00. The marginal revenue product of resource A in Industry 2 is (0.25)($5.00) = $1.25. Therefore, the suppliers of resource A will choose to sell their resource to Industry 2 for $1.25.
