1. A monopolist has constant marginal cost equal to 30 and faces a market demand curve given by the following: Q =180 – 3p. If the monopolist wants to maximize profit then it will choose to produce a quantity equal to ____ resulting in a deadweight loss equal to ____compared to the competitive market.
Answer = 45; 337.5.
2. Consider the market for paintings Brett Whitely. The supply curve is given by the following: Qs =120. The demand curve for Brett Whitely paintings is given by: Q = 200 – p. In the market equilibrium:
Answer = Consumer surplus is positive and demand is price inelastic.
3. The market demand curve for pay TV is given by: Q = 400 – 4 p. Further, assume that the market supply curve for pay TV is given by: p = 25. Following a recent government investigation into the pay TV industry the government imposes a specific tax of 10 on pay TV that must be paid by buyers. In the post tax equilibrium, the revenue raised is___________ and the deadweight loss is _________.
Answer = $2600; 200.
4. Assume that the manufacturer of bottled water is a monopolist with constant average total cost equal to $5. The demand curve faced by this monopolist is given by the following: Q = 100 – 4P. At the market equilibrium for a single price monopolist the price is equal to______ and the deadweight loss is ________.
a. 20; 300.
b. 20; 400.
c. 40; 200.
d. 40; 300.

5. Suppose individuals A and B have the following demand curves for a public good:
QA = 40 – 2p and QB = 40 – p, where Q is the amount of the public good. If the marginal cost of production is constant and equal to 30, the quantity produced in the competitive equilibrium would equal ____ and the efficient outcome is equal to _____:
Answer = 10, 20.
6. Assume that the domestic supply curve for cars is given by P = 50 + QS and the
demand for cars is given by P = 200 -QD. Further, assume that cars can be imported and the world price for cars is equal to 100. If the…
