2) In the U.S. government's 1998 suit against the Microsoft Corporation, a central issue
was whether Microsoft should be allowed to integrate its Internet browser into its
Windows operating system. Microsoft responded that
a.this integration of products is an example of tying, and the U.S. Supreme Court has

b.this integration of products is an example of resale price maintenance, and the U.S.
Supreme Court has consistently ruled that fair trade is a perfectly acceptable and legal
business practice.
c.putting new features into old products is a natural part of technological practice.
d.it would discontinue this integration of products, provided a speedy resolution of the
government's case could
be reached.
3) Labor supply curves are always upward sloping.
a.True
b.False
4) Which of the following is not a reason for the existence of a monopoly?
a.patents
b.marginal-cost pricing
c.economies of scale
d.trademarks
5) Suppose a profit-maximizing monopolist faces a constant marginal cost of $10,
produces an output level of 100 units, and charges a price of $50. The socially efficient
level of output is 200 units. Assume that the demand curve and marginal revenue curve
are the typical downward-sloping straight lines. The monopoly deadweight loss equals
$4,000.
a.True
b.False
6) Phil sells duck calls in a perfectly competitive market. If duck calls sell for $10 each
and average total cost per unit is $11 at the profit-maximizing output level, then in the
long run
a.more firms will enter the market.
b.some firms will exit from the market.
c.the equilibrium price per duck call will fall.
d.average total costs will fall.
7) Which of the following does not describe the hypothesis that changes in technology
have altered the relative demand for skilled and unskilled labor?
a.Firms rely more on computer databases than on paper filing systems so there is an
increased demand for high-skilled computer programmers.
b.Consumers can accomplish many simple banking tasks on an automated teller
machine (ATM) rather than speaking to a bank teller so there is a decreased demand for
low- skilled bank tellers.
c.Transponders in peoples' vehicles can be used to automatically deduct tolls from debit
accounts, reducing the
need for low-skilled toll collectors.
d.Improvements in technology have made tax preparation software easy for an average
citizen to use, reducing the need for high-skilled accountants.
8) Total cost is the
a.amount a firm receives for the sale of its output.
b.fixed cost less variable cost.
c.market value of the inputs a firm uses in production.
d.quantity of output minus the quantity of inputs used to make a good.
9) A certain state legislature is considering an increase in the state gasoline tax.
Representative Campbell argues that an increase in the gasoline tax would harm
low-income drivers disproportionately. Representative Richards responds by saying that
low-income drivers own smaller cars that use less gasoline, and that low-income drivers
therefore would not be harmed disproportionately.
a.Representative Campbell's argument is based primarily on efficiency, while
Representative Richards' argument is based primarily on equality.
b.Representative Campbell's argument is based primarily on equality, while
Representative Richards' argument is based primarily on efficiency.
c.Both representatives' arguments are based primarily on efficiency.
d.Both representatives' arguments are based primarily on equality.

b.ATC would be at its minimum value.
c.the firm would sustain a loss of more than $2,000.
