Lesson 10a: Monopoly: Characteristics and Short Run Equilibrium

Outcomes - What you should learn

TOPICS:

What are Monopolies?

Monopoly Output and Price in the Short-Run

OUTCOMES

List the five characteristics of pure monopoly.

List and give examples of the four barriers to entry.

Describe the demand curve facing a pure monopoly and how it differs from that facing a firm in a purely competitive market.

Why is the demand curve for a monopoly downward sloping?

Compute marginal revenue when given a monopoly demand schedule.

Explain why the marginal revenue is equal to the price in pure competition but marginal revenue is less than price in monopoly.

- Why is the MR curve below the demand curve?

- Why is the extra revenue that a monopoly receives from selling one more unit (MR) less than the price that they charge for that unit (D)?

Determine the price and output level the monopoly will choose given demand and cost information in both table and graphic form.

Draw the short run equilibrium graphs for a pure monopoly that (a) maximizes profit, (b) minimizes loss, and (c) shuts down.
