True / False

1. Unless a good is a Giffen good, the demand curve shifts to the right as income rises.
a. True
b. False
RATIONALE: Unless the good is an inferior good, the demand curve shifts to the right as income rises.

2. A downward sloping income-demand curve indicates that the good is a necessity.
a. True
b. False
RATIONALE: To be more precise, it indicates that a good is an inferior good — but all inferior goods are necessities, and thus the statement is true.

3. For the same sized substitution effect, own-price demand curves for inferior goods are steeper than own price demand curves for normal goods.
a. True
b. False
RATIONALE: This is true because the substitution and income effects point in the same direction for normal goods — thus making the slope of the demand curve shallower than it would be in the absence of the income effect (or in the presence of an income effect that points in the opposite direction.)

4. If a good is quasilinear, its own-price demand curve is vertical.
a. True
b. False
RATIONALE: The own-price demand curve is vertical for goods that are borderline between regular inferior and Giffen, not goods that are borderline between normal and inferior.

5. Goods like exclusive designer clothes carry with them prestige value linked to their price. As a result, some people demand more of such goods as the price increases. For those people, such goods are Giffen goods.
a. True
b. False
RATIONALE: These are luxury goods that are composed of both the physical good as well as the prestige value associated with it. When price increases prestige value, the nature of the good changes when price increases — but the good itself is still a normal good in the sense that, were the prestige value to stay constant, an increase in price leads to less quantity demanded.

6. Assuming the same sized substitution effect, normal goods have steeper cross-price demand curves than inferior goods.
a. True
b. False
