Econ Exam 4
If crude oil is a variable factor of production for a firm, then an increase in the price of crude oil will lead to
a decrease in the firm's supply
One problem with government ownership of natural monopolies is that
government-owned firms have weaker incentives to cut costs than do privately-owned firms
An imperfectly competitive firm is one that
has at least some influence over the market price
A price setter is a firm that
has some degree of control over its price.
A price-taker faces a demand curve that is
horizontal at the market price
The most important challenge facing a firm in a perfectly competitive market is deciding
how much to produce
A rational seller will sell another unit of output
if the cost of making another unit is less than the revenue gained from selling another unit
Both a perfectly competitive firm and a monopolist find that
it is best to expand production until the benefit and the cost of the last unit produced are equal
A pure monopoly exists when
a single firm produces a good with no close substitutes
Which of the following is a defining characteristic of all perfectly competitive markets?
All firms sell the same standardized product
Which of the following is NOT a characteristic of a perfectly competitive market?

For all firms, the additional revenue collected from the sale of one additional unit of output is termed
marginal revenue
The primary objective of an imperfectly competitive firm is to

One problem with antitrust laws is that they
may prevent companies from achieving economies of scale

If a firm operates in an oligopoly, it is

Assume that the production technology required to produce goods X and Y is very similar. If a firm that is producing good X notices that the market price of good Y is rising, it will
shift into producing good Y
Economies of scale exist when
the average cost of production falls as output rises
For a given seller, the accompanying figure shows the relationship between the number of units produced and the opportunity cost of producing an additional unit of output. If the market consists of 50 identical sellers, each with the same opportunity cost as the seller depicted in the figure, then how many units would be supplied in the market at a price of $14 per unit?
17,500
A technological innovation that reduces a firm's cost of producing additional units of output will lead to
an increase in the firm's supply
As price increases, firms in a perfectly competitive market find that it is
beneficial to produce more units of output.
Price discrimination means charging
different prices to different buyers for essentially the same good or service
According to the textbook, the most important and enduring sources of market power are
economies of scale
Patents, which confer market power, are intended to
encourage innovation by helping firms recoup the costs of research and development
A perfectly price discriminating monopolist charges each buyer
exactly his or her reservation price
