Chapter 8: Q.40 (page 213)

Perfectly competitive firm Doggies Paradise Inc. sells winter coats for dogs. Dog coats sell for \(72 each. The fixed costs of production are \)100. The total variable costs are \(64 for one unit, \)84 for two units, \(114 for three units, \)184 for four units, and $270 for five units. In the form of a table, calculate total revenue, marginal revenue, total cost and marginal cost for each output level (one to five units). On one diagram, sketch the total revenue and total cost curves. On another diagram, sketch the marginal revenue and marginal cost curves. What is the profit-maximizing quantity?

Short Answer

Expert verified

4units is the profit-maximizing quantity unit.

Step by step solution

01

Given information

Each dog coat costs $72.

Most popular questions from this chapter

How does a perfectly competitive firm decide what price to charge?

1. A computer company produces affordable, easy-to-use home computer systems and has fixed costs of \(250. The marginal cost of producing computers is \)700 for the first computer, \(250 for the second, \)300 for the third, \(350 for the fourth, \)400 for the fifth, \(450 for the sixth, and \)500 for the seventh.

a. Create a table that shows the company’s output, total cost, marginal cost, average cost, variable cost, and average variable cost.

b. At what price is the zero-profit point? At what price is the shutdown point?

c. If the company sells the computers for \(500, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVC curves to illustrate your answer and show the profit or loss.

d. If the firm sells the computers for \)300, is it making a profit or a loss? How big is the profit or loss? Sketch a graph with AC, MC, and AVC curves to illustrate your answer and show the profit or loss.

Productive efficiency and allocative efficiency are two concepts achieved in the long run in a perfectly competitive market. These are the two reasons why we call them “perfect.” How would you use these two concepts to analyze other market structures and label them “imperfect?”

What is a “price taker” firm?

Firms in a perfectly competitive market are said to be “price takers”—that is, once the market determines an equilibrium price for the product, firms must accept this price. If you sell a product in a perfectly competitive market, but you are not happy with its price, would you raise the price, even by a cent?
