The monopoly’s cost is a function of its output, which is C(Q)=Q2+12, and the monopoly faces the linear inverse demand function: P=24—Q
(1) Calculate the following items: marginal cost, average fixed cost, average variable cost, average total cost, and marginal revenue
(2) Calculate profit-maximizing output and profit-maximizing price, determine its economic profit
C(Q)=Q^2+12
Inverse Demand Function is P=24-Q
Ans 1)
Marginal Cost=dC/dQ=2Q
Average Fixed Cost=Fixed Cost/Q=12/Q
Average Variable Cost=Variable Cost/Q=Q^2/Q=Q
Average Total Cost= AFC+AVC=(12/Q)+Q
Marginal Revenue=d(Revenue)/dQ
Revenue=Price *Quantity=(24-Q)Q=24Q-Q^2
MR=24-2Q
Ans 2)
Profit Maximizing output for monopoly is achieved when MR=MC
24-2Q=2Q
Q=6
Maximizing Output=6 units
Maximizing Price=24-6=$18
Economic Profit at max Price and Quantity is Revenue-Cost=18*6-(6^2)-12=$60

Suppose that a monopoly faces inverse market demand function as P = 70−2Q, and its marginal cost function is MC = 40 – Q. Please answer the following two questions: a. What should be the monopoly’s profit-maximizing output? b. What is the monopoly’s price?
*2.2 If a monopoly faces an inverse demand function of p = 90 − Q , p=90−Q, has a constant marginal and average cost of 30, and can perfectly price discriminate, what is its profit? What are the consumer surplus, total surplus, and deadweight loss? How would these results change if the firm were a single-price monopoly?
Practice Question 4. The inverse demand curve a monopoly faces is p = 30 – Q. The firm's total cost function is C(Q) = 0.5Q² and thus marginal cost function is MC(Q) = Q. (a) Determine the monopoly quantity, price and profit, and calculate the CS, PS and social welfare under the monopoly. (b) Determine the socially optimal outcome and calculate the CS, PS and social welfare under the social optimum. (c) Calculate the deadweight loss due to the monopolist...
Question 3: Consider a monopoly which faces the demand curve P= 55-2Q and having a marginal cost function MC= 2Q-5. a) (2pts) Calculate the marginal revenue (MR) function. b) (2 pts) State the profit maximizing output rule for the monopoly in the short-run. c) (4 pts) What is the profit maximing output level? Next, calculate the price and the profit of the monopoly?
Q2: The demand for a single-price monopolist’s product is Q = 60 – 2P where Q is measured in units and P is measured in $/unit. a) At which price is the demand for the monopolist’s product unit elastic? b) At which prices is the demand for the monopolist’s product elastic? c) At which prices is demand for the monopolist’s product inelastic? d) Suppose the monopoly is currently producing and selling 50 units of output. What price must the monopoly...
The inverse demand curve a monopoly faces is p=20Q^−1/2. The firm's cost curve is C(Q)=4Q. What is the profit-maximizing solution? (Round all numeric to two decimal places.) The profit-maximizing quantity is 6.25. The profit-maximizing price is $8. What is the firm's economic profit? The firm earns a profit of $_________ (Round your response to two decimal places.)
The inverse demand function a monopoly faces is P = 100 − Q. The firm’s cost curve isTC(Q) = 10 + 5Q (f) (4 points) For what value of fixed costs, does the monopolist break even? (g) (4 points) For what value of fixed costs, would be monopolist find it optimal to shut down in the short-run? (h) (4 points) For what value of fixed costs, would be monopolist find it optimal to shut down in the long-run? (i) (4...
A monopoly book publisher with a constant marginal cost (and average cost) of MC = 1 sells a novel in only two countries and faces a linear inverse demand function of p1 = 6 - .5Q1 in Country 1 and p2 = 9 – Q2 in Country 2. What price would a profit-maximizing monopoly charge in each country with and without a ban against shipments between the countries?
consider a monopolist who has a cost function of c(q) = 1/4 Q2 this monopolist faces a demand given by Q(p) = 90 -2P. Solve for the profit maximizing price and quantity produced. Calculate their resulting profits. Show this profit maximizing also graphically. label the price and quantity on their curve. please show all steps.
The inverse demand curve a monopoly faces is p= 120-20. The firm's cost curve is C(Q)= 30 +6Q. What is the profit-maximizing solution? The profit-maximizing quantity is . (Round your answer to two decimal places.) The profit-maximizing price is $ . (round your answer to two decimal places.)
