Scenario 22-1
At issue in a particular city vote is how much to spend, per person, on road repair next year. Among
the 10,000 voters, 1,500 prefer to spend $300 per person, but no more; 2,800 prefer to spend $450
per person, but no more; 3,500 prefer to spend $800 per person, but no more; and 2,200 prefer to
spend $1500 per person, but no more.
60. Refer to Scenario 22-1. The median voter is one who prefers to spend
a.
$300.
b.
$450.
c.
$800.
d.
$1500.
61. Refer to Scenario 22-1. If there is a vote on whether to spend $600 per person or $800 per person,
the median voter will vote to spend
a.
$600 per person and the voting outcome will be $600 per person.
b.
$600 per person and the voting outcome will be $800 per person.
c.
$800 per person and the voting outcome will be $600 per person.
d.
$800 per person and the voting outcome will be $800 per person.

62. Refer to Scenario 22-1. If there is a vote on whether to spend $800 per person or $1100 per person,
the median voter will vote to spend
a.
$800 per person and the voting outcome will be $800 per person.
b.
$800 per person and the voting outcome will be $1100 per person.
c.
$1100 per person and the voting outcome will be $800 per person.
d.
$1100 per person and the voting outcome will be $1100 per person.
63. An implication of the median voter theorem is that, in a race between Republicans and Democrats,
a.
if Republicans want to win, they will take a “middle-of-the-road” stance on many issues.
b.
if Democrats want to win, they will take an extreme stance on many issues.
c.
Republicans and Democrats go to extremes to differentiate themselves from one another.
d.
Republicans and Democrats work hard to identify the fringe voters.
64. When Republicans and Democrats offer similar platforms in an election campaign, a likely explana-
tion is the
a.
Arrow impossibility theorem.
b.
Condorcet paradox.
c.
median voter theorem.
d.
fact that politicians are more interested in the national interest than their own self-interest.
65. In American politics, we often observe that during a campaign, the Democratic and Republican posi-
tions on many issues are similar, which illustrates
a.
Arrow’s impossibility theorem.
b.
the Condorcet paradox.
c.
a Borda count.
d.
the median voter theorem.
66. An implication of the median voter theorem is that
a.
minority views and majority views are given equal weight.

platforms of the major political parties will not differ greatly.
c.
the logic of democracy is fundamentally flawed.
d.
behavioral economics plays a significant role in voting outcomes.
