A monopolist has set her level of output to maximize profit

Economics Dec 07, 2020

A monopolist has set her level of output to maximize profit. The firm's marginal revenue is

$20, and the price elasticity of demand is -3.0. Which of the following prices or price ranges

describe the firm's profit maximizing price:

a. $0-9.

b. $10-19.

c. $20.

d. $21+.

e. This problem cannot be answered without knowing the marginal cost.

Expert Solution

Computation of Firm's Profit Maximizing Price:

Price = Marginal Revenue * [Elasticity / (1 + Elasticity)]

= $20 * [- 3 / (1 - 3)]

= $20 * (-3 / -2)

= $20 * 1.5

= $30

 

So, Firm's Profit Maximizing Price is $30. The correct option should be D "$21+".
