b. If SpaceX wants to maximize profits it should not build the hyperloop as the project will incur losses.The lifetime total revenue from the project is not sufficient to cover costs.The minimum loss from the project when it is operating at full efficiency will amount to 0.8 billion.
c. The welfare from the hyperloop will be maximum when consumer surplus is maximum.
This will be (Maximum price consumers are willing to pay - Price consumer actually pays) ×Maximum Quantity demanded.
or, Consumer surplus= (8-0) ×800 =$ 6400 million or $6.4 billion.
Therefore government should build 800 no. of crossings and charge $0 to maximize welfare.
d. The present cost of the project is 2.4 billion and the maximum wlfare that can be achieved is of $6.4 billion. Therefore if the cost overun is greater than $(6.4 - 2.4)
= $4billion then the project is undesirable as any extra dollar spent beyond $6.4 billion will not cause any further increase in consumer welfare.
decreased in order to reach the efficrent scale. 2. SpaceX is company considering building a hyperloop...
2. SpaceX is company considering building a hyperloop la sealed system of tubes through which passenger pods travel free of air resistance and friction) from San Francisco to New York City. This system would dramatically reduce transportation times along the route. The hyperloop would cost $2.4 billion to build and nothing to maintain a. The following table gives the anticipated demand over the lifetime of the hyperloop. Find total revenue and marginal revenue for the various possible quantities of crossings....

1) 1) A single-price monopolist is currently producing an output level where P-520, MR = $13, ATC = $15, and MC = $14. In order to maximize profits, this monopolist should A) shut down B) decrease production and increase price. C) not change his output level, because he is currently at the profit-maximizing output level. D) increase production and reduce price. E) there is insufficient information to make a recommendation 2) 2) Consider a monopolist that is able to distinguish...

**Only [Harder] Question** Problem 2. Consider a firm that has a cost function of c(y) = 5y 2 + 50, 000. In other words, this is a firm with a fixed cost of $50,000 (which might be something like the cost of rent on the firm’s building, which they have to pay whether they produce any output or not) and a variable cost of $5Y 2 , (which we’ll think of as the cost of the labor and machinery necessary...

5_._ _Minimum Efficient Scale and Natural Monopolies Pandora is a small island with just one power plant, which is a monopolist in the island’s electricity market. The plant’s cost function is ?(?)=0.5?3−20?2 + 282.5 ?, where ? is the number of MW-h of electricity produced per day. This implies the marginal cost curve ?C(?) =1.5 ?2 –40? + 282.50. Daily demand for electricity in Pandora is given by ??(?) = 16 −(1/20)?, where ? is the price of a MW-h...
