6) Figure 21-20
The following graph illustrates a representative consumer's preferences for
marshmallows and chocolate chip cookies:

will the optimizing consumer choose?
a.A

11) Suppose the price of good X falls. As a result, the quantity demanded for good X
increases for a particular consumer. For this consumer, the substitution effect induced
the consumer to purchase more X while the income effect induced the consumer to
purchase less X. We can infer that X is a(n)
a.normal good.
b.inferior good.
c.Giffen good.
d.luxury good.
12) Suppose that a competitive market is initially in equilibrium. Then demand
increases. If entering firms face the same costs as existing firms and sufficient resources
are available for entering firms,
a.the long-run market supply curve will be upward sloping.
b.the long-run market supply curve will be perfectly elastic.
c.in the long run firms will suffer economic losses, leading them to exit the industry.
d.the number of firms will decrease, and the market will become a monopoly.
13) In the market for widgets, the supply curve is the typical upward-sloping straight
line, and the demand curve is the typical downward-sloping straight line. The
equilibrium quantity in the market for widgets is 200 per month when there is no tax.
Then a tax of $5 per widget is imposed. The price paid by buyers increases by $2 and
the after-tax price received by sellers falls by $3. The government is able to raise $750
per month in revenue from the tax. The deadweight loss from the tax is
a.$250.
b.$125.
c.$75.
d.$50.
14) A positive economic statement such as Pollution taxes decrease the quantity of
pollution generated by firms
a.would likely be made by an economist acting as a policy advisor.
b.would require values and data to be evaluated.
c.would require data but not values to be evaluated.
d.could not be evaluated by economists acting as scientists.
