You are the manager of a monopolistically competitive firm. The
inverse demand for your product is given by P = 200 - 10Q and your
marginal cost is MC = 5 + Q.
a. What is the profit-maximizing level of output?
b. What is the profit-maximizing price?
c. What are the maximum profits?
P = 200-10Q and MC = 5+Q
a) Profit maximing level of output is where MR=MC
P = 200-10Q
TR = 200Q - 10Q2 ( as TR = P * Q)
MR = 200-20Q
MC = 5+Q
200 -20Q = 5 + Q
195 = 21Q or Q = 9
b) P = 200 -10*9
P = 200 - 90 = 110
so, profit maximizing price is $110.
c) Profits = TR -TC
we have TC = 5Q + 0.5Q2
profits = (110 * 9 ) - ( 5*9 + 0.5*81)
profits= 990 - ( 45 + 40.5)
profits = $904.5

You are the manager of a monopolistically competitive firm, and your demand and cost func- tions are given by Q = 18 - 3P C(Q) = 120 – 12Q + 3Q2 Find the inverse demand function. Determine the profit maximizing price and level of production. Calculate your firm's maximum profits.
You are the manager of a monopolistically competitive firm. Your demand and total costs are represented by Demand Q = 36 – 4P Total cost = 4 + 4Q + Q2. 2a What is the expression for marginal revenue? 2b What is the expression for marginal cost? 2c To maximize profit what output level should it make? 2d To maximize profit at what price should it sell? 2e What is the maximum value of profit?
Suppose the inverse demand curve for a commodity in a perfectly competitive market takes the functional form: P (Q) = -.1Q + 10. Additionally, the firm’s marginal cost (MC) takes the following functional form: MC = 4 + 2Q. Recalling that a perfectly competitive firm is a price-taker in the market and its profit-maximizing output level (Qe) is always found by equating its price with its marginal cost: P = MC. Given all this, how much output (Qe) should the...
A monopolistically competitive firm faces the following demand schedule for its product. In addition, the firm has total fixed costs equal to 20. Price (dollars) Quantity 30 1 26 2 22 3 21.4 4 14 5 10 6 6 7 If the firm has a constant marginal cost of $7 per unit, what profits will the firm earn at the profit-maximizing level of output?
Suppose there is a monopolistically competitive market with n identical firms, such that each firm produces the same quantity, q. Further, the market is in the monopolistically competitive long-run equilibrium. You are given the following: Inverse market demand: P 10-Q Total market output: Qnxq Marginal revenue: MR 10n+ 1)xq Total cost: C(q)-5+q Marginal cost: MC 2xq In long-run equilibrium, each firm earns zero economic profit. In long-run equilibrium, the number of firms, n, is and each firm produces units) of...

2. (10 points) You are the manager of a monopolistically competitive firm. The present demand curve you face is P = 100 – 4Q. Your cost function is C(Q) = 50 + 8.5Q2. a. (3 points) What level of output should you choose to maximize profits? b. (2 points) What price should you charge? c. (5 points) What will happen in your market in the long run? Explain.
You the newly appointed manager of a profit maximizing monopolistically competitive firm. You decided to ensure that the firm is actually charging the profit maximizing price for its product and is producing the profit maximizing quantity. Your marketing group estimates that the demand curve faced by your firm is expressed as: P = 900 – 2Q and its total costs is expressed as: C(Q) = 2Q + Q2 a. What price would you charge? And what level of output would...

a) Why is a monopolistically competitive firm less efficient than a perfectly competitive firm? It produces at an output that is lower than its minimum efficient scale (MES) It earns positive economic profits in the long run It deters entry of new firms by putting up entry barriers All of the answers are correct b) Suppose a monopolistically competitive firm has MC=4Q+5. Its demand is P=145-3Q and marginal revenue is MR=145-6Q. What is its profit-maximizing output level? 17 14 16...
