Table 10-5
Refer to Table 10-5, which lists the values of Harry Taber's marginal utility and
marginal utility per dollar for Italian submarine (sub) sandwiches and tacos. Assume
that the price of a sub sandwich is $4 and the price of a taco is $2. When Harry's income
is $14 he buys two Italian sub sandwiches and three tacos. The last column lists the
values of the marginal utility per dollar for tacos when the price of a taco decreases to
$1. Complete this statement: As a result of the change in price
A) Harry's purchasing power has increased. He will reduce his consumption of tacos so
he can buy one more sub. This is an example of the substitution effect of a price change.
B) Harry's purchasing power has increased. If tacos are a normal good for Harry he will
buy fewer tacos. This is an example of the income effect of a price change.
C) Harry's purchasing power has increased. If tacos are a normal good for Harry he will
buy more tacos. This is an example of the income effect of a price change.

Which of the following statements is true?
A) The supply of oil is very elastic over short time periods but becomes perfectly
inelastic over time. A given shift in supply results in a greater increase in the price of oil
when the supply of oil is perfectly inelastic.
B) The supply of oil is very inelastic over short time periods but becomes more elastic
over time. A given shift in supply results in a smaller increase in the price of oil when
the supply is more elastic.

over time the price of oil increases significantly.
D) Over short periods of time increases in the demand for oil are greater than increases
in the supply of oil. Over the long run increases in the demand and the supply of oil are
about equal. As a result, the price of oil increases greatly in the short run but is stable in
the long run.
