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 the sub
sandwiches is $4 and the price of tacos 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 tacos 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.
D) Harry’s purchasing power has increased. Harry buys fewer tacos. This is an example
of the substitution effect of a price change
If the marginal cost curve is below the average variable cost curve, then
A) average variable cost is increasing.
B) average variable cost is decreasing.
C) marginal cost must be decreasing.
D) average variable cost could either be increasing or decreasing.
