Economists use the term imperfect competition to describe:
those markets which are not purely competitive.
A one-firm industry is known as:
pure monopoly.
An industry comprised of a very large number of sellers producing a standardized product is known as:
pure competition.
An industry comprised of a small number of firms, each of which considers the potential reactions of its rivals in making price-output decisions is called:
A purely competitive seller is:
a "price taker."
Which of the following is not a characteristic of pure competition?
price strategies by firms.
If a firm in a purely competitive industry is confronted with an equilibrium price of $5, its marginal revenue:
will also be $5
For a purely competitive seller, price equals:
A. average revenue.
B. marginal revenue.
C. total revenue divided by output.

The answer is D. All of these.
Which of the following statements is correct?

Pure monopoly means:
a single firm producing a product for which there are no close substitutes.
A pure monopolist is:
a one-firm industry.
Which of the following best approximates a pure monopoly?
the diamond market.
Which of the following is not a barrier to entry?
What do economies of scale, the ownership of essential raw materials, and patents have in common?
they are all barriers to entry.
A non-discriminating pure monopolist's demand curve:
lies above its marginal revenue curve.
With respect to the pure monopolist's demand curve it can be said that:
the price exceeds marginal revenue at all outputs greater than 1.
Price exceeds marginal revenue for the pure monopolist because the:
demand curve is down-sloping.
The marginal revenue curve for a monopolist:
becomes negative when output increases beyond some particular level.
Which of the following is characteristic of a pure monopolist's demand curve?
It is the same as as the market demand curve.
For a pure monopolist marginal revenue is less than price because:
when a monopolist lowers price to sell more output, the lower price applies to all units sold.

The term oligopoly indicates:
a few firms producing either a differentiated or homogeneous product.
The automobile, household appliance, and automobile tire industries are all illustrations of:
differentiated oligopoly.
Barriers to entry in oligopolistic industries may consist of:
ownership of essential resources.
Oligopolistic industries:
may produce either standardized or differentiated products.
The kinked-demand curve of an oligopolist is based on the assumption that:
competitors will follow a price cut but ignore a price increase.
