6. A company is considering building a bridge across a river. The bridge would cost $2 million to build and nothing to maintain. The following table shows the company’s anticipated demand over the lifetime of the bridge:
A. I company were to build the bridge hat would be its profit-maximizing price? Would that be the, efficient level of output? Why or why not?
b, If the company is interested in maximizing profit, should it build the bridge?
7. i’f the Placebo Drug Company holds a patent on one of Its a. Assuming that ,the production of the drug involves rising marginal cost.Placebo’s profit maximizing price and quantity. Also show Placebo’s profits.

8.Run the only saloon in town. Larry wants to sell as many drinks as possible losing money. Curly wants the saloon to.bring in as much revenue as possible. Moe wants to
make the largest possibly profits. Using a single diagram of the saloon’s demand curve and its cost quantity combination favored by each of the three partners. Explain

10. The Best Computer Company just developed a new computer chip, on which it immediately acquires a patent.
a. Draw a diagram that shows the consumer surplus, producer surplus, and total surplus in the market for this new chip.
b. What happens to these three measures of surplus.
11 Explain why a monopolist will never produce a quantity at which the demand curve is inelastic. (Hint: If demand is inelastic and the firm ‘raises its price, what happens to total, revenue and total costs?)
12′. Singer Avril Lavigne ‘has a monopoly over a scarce resource: herself. She is the only person who can produce an Avril Lavigne concert.Does this fact imply that the government should regulate the prices, of her concerts? Why or why not?

This question considers the implications of costly price discrimination. To keep things simple, let’s assume that our monopolist’s production costs are simply proportional to output so that average total cost and marginal cost are constant and, equal to each other.
a. Draw the cost, demand, and marginal-revenue curves for the monopolist. .Show the price the monopolist would charge without price discrimination.
b. In your diagram. mark the area equal to the monopolist’s profit and call it X. Mark the area equal
to consumer surplus and call it Y. Mark the area equal to the deadweight loss and call it.
