Economic Profit and Externalities

The video tutorial by Will from Learn Rider covers the 2009 AP Microeconomics FRQ question on monopolies. It explains how to draw and analyze a monopoly graph, focusing on profit-maximizing quantity, price, and economic profit. The video discusses the impact of a lump sum subsidy, the scenario of zero economic profit, and the difference between accounting and economic profit. It concludes with the effect of external benefits on the socially optimal quantity of cable services.

What is the primary focus of the 2009 AP Microeconomics FRQ question discussed in the video?

• Perfect competition

• Monopolistic competition

• Monopolists

• Oligopoly

In the context of a monopolist, where is the profit-maximizing quantity determined?

• Where demand equals supply

• Where marginal cost equals average total cost

• Where marginal revenue equals marginal cost

• Where price equals marginal cost

How does a lump sum subsidy affect the profit-maximizing quantity for Cable Now?

• It has no impact on the quantity

• It decreases the quantity

• It doubles the quantity

• It increases the quantity

What is the effect of a lump sum subsidy on marginal cost?

• Decreases marginal cost

• Eliminates marginal cost

• Increases marginal cost

• No change in marginal cost

When the government requires Cable Now to produce at zero economic profit, what is the relationship between demand and average total cost?

• Demand is less than average total cost

• Demand is greater than average total cost

• Demand equals average total cost

• Demand is unrelated to average total cost

What is the nature of accounting profit when economic profit is zero?

• Undefined

• Negative

• Zero

• Positive

How do external benefits associated with watching TV affect the socially optimal quantity of cable services?

• They decrease the socially optimal quantity

• They have no effect on the socially optimal quantity

• They increase the socially optimal quantity

• They make the socially optimal quantity zero

What type of externality is associated with the benefits of watching TV?

• Neutral externality

• No externality

• Positive externality

• Negative externality

If a positive externality is present, what happens to the demand for TV?

• Demand increases

• Demand remains constant

• Demand decreases

• Demand becomes unpredictable

What is the result of a positive externality on the quantity supplied?

• Quantity supplied decreases

• Quantity supplied remains the same

• Quantity supplied increases

• Quantity supplied becomes zero
