Suppose that a monopolist has a constant average total cost of production and marginal cost of production equal to $6, and has a demand for its product represented as

price	quantity bought and sold (units)
$10	1
$9	2
$8	3
$7	4
$6	5

Calculate the total and marginal revenue for each quantity produced and sold
Find the profit-maximizing (optimal) quantity produced and sold and the price/unit.
Calculate the profit or loss at the optimal quantity of production and sales.

Expert Solution

(a)

Total revenue is calculated as follows -

Total revenue = Price * Quantity

Marginal revenue is calculated as follows -

Marginal revenue = Change in total revenue/Change in quantity

Based on the above formula, following is the complete table -

Price	Quantity	Total Revenue	Marginal Revenue
$10	1	$10	$10
$9	2	$18	$8
$8	3	$24	$6
$7	4	$28	$4
$6	5	$30	$2

(b)

In order to maximize profit, a monopolist produce that level of output corresponding to which MR equals MC.

The marginal cost is $6.

The MC equals MR corresponding to 3 units of output.

The price corresponding to 3 units of output is $8 per unit.

So,

The profit-maximizing quantity produced and sold is 3 units.

The price is $8 per unit.

(c)

Calculate the profit -

Profit = Total Revenue - Total Cost

Profit = [Price * quantity] - [ATC * quantity]

Profit = [$8 * 3] - [$6 * 3] = $24 - $18 = $6

Thus,

The profit at the optimal quantity is $6

41. A monopolist has a constant marginal and average cost of $10 and faces a demand curve of QD = 1000 – 10P. Marginal revenue is given by MR = 100 – 1/5Q. a. Calculate the monopolist’s profit-maximizing quantity, price, and profit. b. Now suppose that the monopolist fears entry, but thinks that other firms could produce the product at a cost of $14 per unit (constant marginal and average cost) and that many firms could potentially enter. How could...

A monopolist is able to produce at a constant average total and marginal costs (ATC = MC = 5). The firm faces a market demand curve with the following equation P = 53 - Q. *Determine the equation that gives the firm's marginal revenue curve. *Determine the firm's profit-maximizing output level and the price that they would charge for their product. Determine the monopolist's profits. *Determine the output level that would be produced within this firm under perfect competition. (P...

In using the graph for a monopolist, with demand, marginal revenue, marginal cost, and average total cost curves, explain how you find the profit maximizing level of output. (Note that this question asks about OUTPUT. The next question asks about PRICE.) Profits are maximized at the quatnity where total revenue is highest above total cost Profits are maximized at the quantity where ATC hits its minimum Profits are maximized at the quantity where marginal revenue equals marginal cost Profits are...

A monopolist can produce at a constant average and marginal cost of ATC = MC = $5. It faces a market demand curve given by Q = 53 - P. 5. Suppose there are N firms in the industry, all with the same constant MC = $5. Find the Cournot equilibrium. How much will each firm produce, what will be the market price, and how much profit will each firm earn? Also show that as N becomes large, the market...

A monopolist with a constant marginal cost of production of 10 maximizes its profit by choosing to produce where the price elasticity of demand is –3. (Recall that MR = p(1 + 1/ε) where MR is marginal revenue, p is price and ε is the point price elasticity of demand.) A. If price is decreased (from its profit maximizing level) by a small amount, revenue of the monopolist will increase. B. If the monopolist’s fixed cost increases, its profit maximizing...

A monopolist (Firm 1) may be a low-cost type, with constant marginal cost of production 10, or a high-cost type, with constant marginal cost of 20, with probabilities p and 1-p respectively. It has no fixed cost. Only the monopolist knows his type. The game has two stages. In stage one, a potential entrant (Firm 2) with constant marginal cost of 15 decides whether to enter the market. Entry requires a fixed investment of $100. If Firm 2 enters the...

A monopolist can produce a constant average (and marginal) cost of AC=MC=$5. It faces a market demand curve given by Q=53-P. A) Consider Problem 2 in the Homework 12 Supplement. Suppose a second firm enters the market. Let Q1 be the output of the first firm and Q2 be the output of the second. Market demand is now given by Q1+Q2 = 53-P. Assuming that this second firm has the same costs as the first, how much will each firm produce...
