A Good Is Characterized By Network Economies If It
A monopolistically competitive firm is one:
of many firms that sell products that are close but not perfect substitutes.
A good is characterized by network economies if it:
becomes more valuable as more people own it.
A natural monopoly is a monopoly that arises from:
economies of scale.
The profit-maximizing level of output for this monopolist is ______ units per day.
F
MC = MR at F units of output.
Suppose the table below describes the demand for a good produced by monopolist.
Picture
The monopolist's marginal revenue from selling the 4th unit of output is less than $7 because:
it has to charge $1 less for each of the first 3 units of output.
Thus, while it gains $7 from selling the 4th unit, it loses $3 because it has to charge $1 less for the first 3 units. Thus, marginal revenue is equal to $7 - $3 = $4.
Suppose a perfectly competitive firm and a monopolist are both charging $5 for their respective products. From this, one can infer that:
the marginal benefit from selling an additional unit of output is $5 for the competitive firm and less than $5 for the monopolist.
Imagine that you are an entrepreneur, making designer t-shirts in your garage. Your total cost (in dollars) is given by the equation TC = 300 + 10Q, where Q represents the number of t-shirts you make. Your fixed cost is $______, and your marginal cost is $______.
300; 10
Perfect competition is socially efficient and monopoly is not because under perfect competition price is ______ while under monopoly price is ______.
equal to MC; greater than MC
The figure below shows the demand curve, marginal revenue curve, marginal cost curve and average total cost curve for a monopolist.
Picture
The socially optimal level of output is:
...
A perfectly price discriminating monopolist charges each buyer:
exactly his or her reservation price.
Suppose the table below describes the relationship between price and quantity demanded for a monopolist.
Picture
If the marginal cost of producing each unit of output is $5, then this monopolist maximizes its profit by charging ______ per unit.
$8
If a monopolist's marginal revenue exceeds its marginal cost at its current level of output, then to maximize its profit the monopolist should:
increase output until marginal revenue equals marginal cost.
If a firm collects $80 in revenue when it sells 4 units, $100 in revenue when it sells 5 units, and $120 in revenue when it sells 6 units, then one can infer the firm is a(n):
perfectly competitor.
If a natural monopoly decreases the quantity of output it produces, then:
its average cost will increase.
Suppose a monopolist faces the demand curve shown below:
Picture
If you were to draw the monopolist's marginal revenue curve, it would:
