Question 10

Which of the following equations best represents deadweight loss ($$DWL) in a $$monopoly market?

Accepted Answer

$$DWL = \frac{1}{2} 	imes (P_{m} - MC) 	imes (Q_{c} - Q_{m})$$

Question 11

Accepted Answer

Question 12

Accepted Answer

Rent seeking increases inefficiency by raising deadweight loss.

Question 13

Suppose a monopoly faces a demand curve $$P = 100 - 2Q$$ and a constant marginal cost $$MC = 20. If $$the monopoly spends resources on rent seeking, what happens to the area between the demand and supply curves at the monopoly quantity?

Accepted Answer

The area representing deadweight loss increases.

Question 14

Which of the following is a real-world example of rent seeking?

Accepted Answer

Question 15

If a monopoly's rent seeking leads to higher barriers to entry, what is the likely long-term effect on market competition?

Accepted Answer

Market competition decreases.

Question 16

Which of the following best describes deadweight loss in a monopoly market?

Accepted Answer

Question 17

A monopoly produces at quantity $$Q_{m}$$ and price $$P_{m}$$, while the competitive market would produce at $$Q_{c}$$ and price $$P_{c}. $$Which formula shows the deadweight loss caused by monopoly?

Accepted Answer

$$DWL = \frac{1}{2} 	imes (Q_{c} - Q_{m}) 	imes (P_{c} - P_{m})$$

Question 18

Which of the following is a plausible effect of rent seeking on the average total cost ($$ATC) of a $$monopoly?

Accepted Answer

$$ATC$$ increases due to resources spent on rent seeking.

Question 19
