1. Assume that the demand curve is given by Q = 1000 – 0.25P. What is the inverse demand curve?
B) Using the inverse demand curve you solved for in 1, solve for the total revenue for this
Monopolist.
C) Using the total revenue curve you solved for in 2, solve for the marginal revenue curve.
D) Assume that Marginal costs are given by 100 + 2Q. What is the profit-maximizing quantity and
price for the monopolist?
E) Now, turn your attention to the Excel Spreadsheet. What is the Profit Maximizing quantity and
price for the monopolist?
Assume that the demand curve is given by Q = 1000 – 0.25P.
A) Inverse demand curve is given by
Q = 1000 - 0.25P
0.25P = 1000 - Q
P = 1000/0.25 - Q/0.25
P = 4000 - 4Q
B) Total revenue for this Monopolist is R = PQ
R = (4000 - 4Q)Q
R = 4000Q - 4Q^2
C) Marginal revenue curve is derivative of R
MR = dR/dQ
MR = 4000 - 8Q
D) Assume that Marginal costs are given by 100 + 2Q.
At profit maximizing quantity we have MR = MC
4000 - 8Q = 100 + 2Q
3900 = 10Q
Q = 390 units
P = 880 per unit
E) It is same as D)
Q = 390 units
P = 880 per unit
Both MR = MC = $880
Q | MR | MC |
0 | 4000 | 100 |
100 | 3200 | 300 |
200 | 2400 | 500 |
300 | 1600 | 700 |
350 | 1200 | 800 |
390 | 880 | 880 |
400 | 800 | 900 |

1. Let the market demand curve be P=1000 - 10Q. Assume the market is controlled by a monopolist. Let fixed cost be $10,000 and Marginal Costs (MC)=20Q. a) What is the profit maximizing output? b) What is the monopolist's total revenue at the profit maximizing output? c) How much profit is the monopolist earning? d) Assume the government breaks up the monopolist in order to create a perfectly competitive market of identical firms. Assume the MC curve is now the...
You are a monopolist in a market with an inverse demand curve of: P=10-Q. Your marginal revenue is: MR(Q)=10-2Q. Your cost function is: C(Q)=2Q, and your marginal cost of production is: MC(Q)=2. a) Solve for your profit- maximizing level of output, Q*, and the market price, P*. b) How much profit do you earn?
Suppose a monopolisti has a demand curve that can be expressed as P -19 minus Q. Turn on the police marginal revenue curve can be expressed as MR-90-2Q. The monopolist has constant marginal cost and average total cost of $10. Find the deadweight loss of a profit maximizing monopolist
Problem 1e. The slope of the demand curve indicates that if the price of Fluff increases by 20 cents, consumers will buy one less unit. Determine what happens to profit if price is increased by calculating the new profit level for Fluff when price is set 20 cents higher than the profit-maximizing price. problem 2 Probem 3 Consider the graph, which illustrates the demand for Fluff. Fluff can be produced at a constant marginal and average total cost of $4...

A monopolist faces a market demand curve given by Q=70-P a. If the monopolist can produce at constant average and marginal costs ofAC-MC-6, what output level will the monopolist choose to maximize profits? What is the price at this output level? What are the monopolist's profits? b. Assume instead that the monopolist has a cost structure where total costs are described by C(Q) = 0.25Q2 - 5Q + 300. With the monopolist facing the same market demand and marginal revenue, what price-quantity combination will be chosen now...
The inverse demand curve for a monopolist's product is P=-Q/2 +60 and the TC curve for the monopolist is TC = 10Q + 200. How do you find the profit maximizing quantity and he profit maximizing price? Thanks!
