Produce the high quantity
Monopolistic competition is characterized by firms:

licenses
Which phrase would be most characteristic of pure monopoly?
single seller
Kim, if you and Francis were a monopoly and made 100 lunches and charged $11 per lunch, what would your profits be?
$1,000
Answer the next question(s) based on the following payoff matrix for a duopoly in which the numbers indicate the profit in thousands of dollars for a high-price or a low-price strategy Refer to the above payoff matrix. If both firms collude to maximize joint profits, the total profits for the two firms will be:
$1,250,000
Okay, so if I am making 60 lunches and Francis holds to the agreement and keeps making 50 lunches, what is the maximum price i can charge per lunch?
$10
Kim, to maximize profits as a monopolist, what price would you charge for each of the 100 lunches?
$11 per lunch
Refer to the above table. If the firm shuts down in the short run, the total cost will be:
$2,500
Kim, I just came from Francis's truck. He has make 100 lunches and you have made 60. What is the maximum price that you can charge for your lunches?
$5 = 21 - 0.1 (100+6) - $5
Got it. And we would both charge $11 per lunch, so what would we each earn in profit>
$500
What are my profits if I am making 60 lunches and selling them for $10 each when my costs are $1 a lunch?
$540
Kim, Francis is going to increase the number of lunches he makes to 60, so what is the maximum price you each can charge for your lunches?
$9 = 21 - 0.1 (120) - $9
Increase my number of lunches to 60
....

Assume that in a monopolistically competitive industry, firms are earning economic profit. This situation will:
Attract other firms to enter the industry because the barriers to entry are low
Monopolistic competitive firms are productively inefficient because production occurs where:
Average total cost is greater than the minimum average total cost
Refer to the above graph. Which point is the shutdown point for the firm?
B
The supply curve for a pure monopolist:

If your costs remain the same at $1 per lunch, what are your profits now?
Francis and I will each earn $480 in profits.
Yes, that is what Francis was so upset about. What happened to Francis's profits when you increase your number of lunches?

Compared to the purely competitive firm, a pure monopoly:
Is able to use barriers to entry and maintain positive economic profits in the long run
A purely competitive firm does not try to sell more of its product by lowering its price below the market price because:

Refer to the above graph of a representative firm in monopolistic competition. What does line 1 represent?

Many people believe that monopolies charge any price they want to without affecting sales. Instead, the output level for a profit-maximizing monopoly is determined by:
Marginal cost = marginal revenue
Refer to the above graph for a firm in pure competition. Line B represents:

A firm should increase the quantity of output as long as its:
Marginal revenue is greater than its marginal cost
A major reason that firms form a cartel is to:

The same as the profits for a purely competitive firm
Firms in an industry will not earn long-run economic profits if:
There is free entry and exit of firms in the industry
So Kim, when you both play your dominant strategy, where do you end up? What profits do you both earn?
We both earn $480 in profit.
Kim, what do you and Francis earn in profits if you are each making 100 lunches?
We both earn zero profit.
Kim, if you and Francis were not competitors, but were instead one firm - a monopoly - what would be the profit-maximizing number of lunches to make per lunch hour?
We would make a total of 100 lunches to maximize our monopoly profits.

horizontal
Assuming no economies of scale and identical costs, if the firms in a purely competitive industry were replaced by a profit-maximizing monopolist, the likely result would be a(n):
increase in price and reduced output
The demand curve faced by a purely monopolistic seller
is downward sloping, whereas that facing the purely competitive firm is perfectly elastic.
A non-discriminating pure monopolist's demand curve:
lies above its marginal revenue curve
U.S. pharmaceutical companies charge different prices for prescription drugs to buyers in different nations, depending on elasticity of demand and government-imposed price ceilings. U.S. pharmaceutical companies, for profit reasons, oppose laws allowing reimportation of drugs to the United States because reimportation would
make it much more difficult to maintain the differing prices.
