Diagrammatic Analysis of Monopoly Market Structure

The video tutorial explores the market structure of monopoly, focusing on how monopolists maximize profits by equating marginal revenue with marginal cost. It discusses the role of barriers to entry in sustaining supernormal profits in the long run and explains why monopolists are considered price makers. The tutorial also examines the effects of changes in demand and costs on monopoly profits and addresses scenarios where monopolists may incur economic losses, leading to potential market exit. The session concludes with a recap of key concepts and the implications of monopoly market dynamics.

What is the relationship between the demand curve and the average revenue curve for a monopolist?

• The demand curve is twice as steep.

• They are identical.

• They intersect at the origin.

• The average revenue curve is horizontal.

Why do monopolists earn supernormal profits in the long run?

• Because they produce at maximum capacity.

• Due to constant demand.

• Because of barriers to entry.

• Due to government subsidies.

How does a decrease in demand affect a monopolist's supernormal profits?

• It decreases supernormal profits.

• It has no effect on profits.

• It increases supernormal profits.

• It leads to economic losses.

What happens to a monopolist's profits if costs increase?

• The firm shuts down immediately.

• Profits decrease.

• Profits remain unchanged.

• Profits increase.

Under what condition will a monopolist continue operating in the short run despite making losses?

• When average revenue is above average variable cost.

• When average cost is below average revenue.

• When marginal cost is zero.

• When total revenue is negative.

What is the shutdown point for a monopolist?

• When total cost is zero.

• When marginal cost equals marginal revenue.

• When average revenue is below average variable cost.

• When average revenue equals average cost.

Why are monopolists considered price makers?

• They have no control over prices.

• They follow government pricing guidelines.

• They determine price by choosing output level.

• They can set any price they want.
