The figure to the right shows the market demand for electricity and the average total cost and
marginal cost of producing electricity for a utility company.
Suppose the utility company is a regulated natural monopoly. If government regulators want to
achieve economic efficiency, then they will regulate a price of $ per kilowatt hour. (Enter a
numeric response using a real number rounded to two decimal places)
Now suppose instead that government regulators want to eat the lowest price such that the utility
company will not suffer a loss so that it will continue to produce in the long run. If so, then i
government regulators will set a price of $ per kilowatt hour.

Graphically show a monopoly firm that currently sells 250 units of output at a price of $60/unit, where the marginal revenue of the 250th unit is $40, the marginal cost of the 250th unit is $50, and the average total cost at 250 units is $60. [Hint: Based on the information given, is the quantity you’re asked to show the profit-maximizing quantity? Think about what has to be true for profit-maximization.]
Based on the graph and assuming the firm attempts to profit maximize (and succeeds), what would happen to price, quantity, MR, MC, and ATC? (rise, fall, or stay the same?)
Suppose that a monopolist’s demand curve is P = 9 – 2*Q. Marginal cost is expressed as follows: MC = 0.5*Q.
What is the profit-maximizing price (P) the monopoly should set? What would be the output (Q) at that price?
What are the current values for the consumer and producer surpluses (CS and PS)? Is it possible to calculate the profit made by the monopolist? If so, how much is it? If not, what other information would be needed to do that?
What would be the 2 key options for a government regulator to increase the consumer surplus (CS) and reduce the producer surplus (PS)? Explain briefly the pros and cons of one of the options!

- Use the graph to the right for a monopoly to answer the questions. What quantity will the monopoly produce, and what price will the monopoly charge? The monopoly will produce 84 units and charge $ 3.4 per unit. (Enter numeric responses using real numbers rounded to two decimal places.) Suppose the government decides to regulate this monopoly and imposes a price ceiling of $2.60 (in other words, the monopoly can charge less than $2.60 but can't charge more). Now what quantity will the monopoly produce, and what price will the monopoly charge?

Since so much e‑commerce is close to this model—where the fixed cost of inventing the product and satisfying government regulators is the only cost that matters—the MC = 0 case will be more important in the future than it was in the past. For each demand curve, calculate the profit-maximizing level of output and price as well as the monopolist's profit. a. ?=200−?P=200−Q, fixed cost = 1,000. Profit‑maximizing output Q = Profit‑maximizing price P = $ Monopolist's profit: $ b. ?=4,000−?P=4,000−Q, fixed cost = 900,000 (Driving the point home from part a) Profit‑maximizing output Q = Profit‑maximizing price P = $ Monopolist's profit: $ c. ?=120−12?P=120−12Q, fixed cost = 1,000…arrow_forwardIs a monopoly still subject the laws of supply and demand?

Your experience running the company for many years has taught you that market demand for your service can be described by the demand function: p = 20 - Q. The cost function is c =q². Therefore, marginal cost equals 2q. Quantity refersto square metre of road resurfacing. Note the Q denotes aggregate market demand and q denotes your production. Of course, if you are the only supplier than q = Q. a) Compute profit maximising price and output. Compute profits. b) The monopoly profit that you have been earning has attracted attention from another firm that will set up operations in South Koreaand compete for market share. You are concerned with losing market share and profit. So, you offer the potential entrant the following deal. Both firms agree to maximise industry profits (joint profits).

If it were to reduce the price of its product to $5.80 per unit, the quantity demanded, and hence its output, would rise to 11 units per week. If the total costs of producing 11 units were equal to $48.70 per week, would the marginal revenue of producing the 11th unit be greater or less than the marginal cost of producing that unit? How would the firm's weekly economic profits be affected if the firm were to produce the 11th unit?
