Refer to Figure 27-3. Suppose Paul begins with $900 in wealth. Starting from there,
a.
Paul would be willing to accept a coin-flip bet that would result in him winning $200 if the result
was “heads”
or losing $200 if the result was “tails.”
b.
the pain of losing $200 of his wealth would equal the pleasure of adding $200 to his wealth.
c.
the pain of losing $200 of his wealth would exceed the pleasure of adding $200 to his wealth.

Figure 27-4. The figure shows a utility function for Alex.
24.
Refer to Figure 27-4. From the appearance of Alex’s utility function, we know that
a.
the pain that Alex would experience if he lost $500 of his wealth would exceed the pleasure that
he would
experience if he added $500 to his wealth.
b.
the pleasure that Alex would experience if he added $500 to his wealth would exceed the pain
that he would
experience if he lost $500 of his wealth.
c.
the property of increasing utility does not apply to Alex.
d.
the property of diminishing marginal utility does not apply to Alex.
25.
Refer to Figure 27-4. From the appearance of Alex’s utility function, we know that
a.
if Alex owns a house, then he definitely would buy fire insurance provided the cost of the
insurance was
reasonable.
b.
Alex would voluntarily exchange a portfolio of stocks with a high average return and a high
level of risk for a
portfolio with a low average return and a low level of risk.
c.
Alex is risk averse.
d.
Alex is not risk averse.
26.
Refer to Figure 27-4. If most people’s utility functions look like Alex’s utility function, then it is
easy to explain
why
a.
people buy various types of insurance.
b.
we observe a trade-off between risk and return.
c.
most people prefer to hold diversified portfolios of assets to undiversified portfolios of assets.
d.
None of the above are correct.

Figure 27-5. The figure shows a utility function for Dexter.
27.
Refer to Figure 27-5. In what way(s) does the graph differ from the usual case?
a.
The utility function shown here is upward-sloping, whereas in the usual case the utility function
is downward-
sloping.
b.
The utility function shown here is bowed downward (convex), whereas in the usual case the
utility function is
bowed upward (concave).
c.
On the graph shown here, wealth is measured along the horizontal axis, whereas in the usual
case saving is
measured along the horizontal axis.
d.
On the graph shown here, utility is measured along the vertical axis, whereas in the usual case
satisfaction is
measured along the vertical axis.
28.
Refer to Figure 27-5. From the appearance of the graph, we know that
a.
Dexter’s level of satisfaction increases by more when his wealth increases from $1,001 to
$1,002 than it
does when his wealth increases from $1,000 to $1,001.
b.
Dexter’s level of satisfaction increases by less when his wealth increases from $1,001 to $1,002
than it does
when his wealth increases from $1,000 to $1,001.
c.
Dexter’s level of satisfaction increases by the same amount when his wealth increases from
$1,001 to
$1,002 as it does when his wealth increases from $1,000 to $1,001.
d.
None of the above answers can be inferred from the appearance of the utility function.
29.
Refer to Figure 27-5. From the appearance of the utility function, we know that
a.
Dexter is risk averse.
b.

satisfaction when his
wealth decreases by X dollars.
c.
the property of diminishing marginal utility does not apply to Dexter.
d.
All of the above are correct.
30.
Refer to Figure 27-5. From the appearance of the utility function, we know that

b.
Dexter gains more satisfaction when his wealth increases by X dollars than he loses in
satisfaction when his
wealth decreases by X dollars.
c.
the property of decreasing marginal utility applies to Dexter.
d.
All of the above are correct.
31.
Refer to Figure 27-5. Suppose the vertical distance between the points (0, A) and (0, B) is 12.

b.
Dexter’s subjective measure of his well-being would increase by more than 12 units.
c.
Dexter would change from being a risk-averse person into a person who is not risk averse.
d.
Dexter would forgo the insurance he bought when his wealth was $1,300.
32.
Refer to Figure 27-5. Suppose Dexter begins with $1,300 in wealth. Starting from there,
a.
the pain of losing $500 of his wealth would equal the pleasure of adding $500 to his wealth.
b.
the pain of losing $500 of his wealth would exceed the pleasure of adding $500 to his wealth.
c.
the pleasure of adding $500 to his wealth would exceed the pain of losing $500 of his wealth.
