Refer to Figure 6-6. As price falls from PA to PB, the quantity demanded increased the most along D1; therefore
D1 is more elastic than D2 or D3
refer to figure 6-6. as price falls from PA to PB, the quantity demanded increases the most along D1; therefore,
D1 is more elastic than D2 or D3.

a luxury
economists estimated that the price elasticity of beer is -0.30 and the income elasticity of beer is 0.09. This means that
an increase in the price of beer will lead to an increase in revenue for beer sellers and beer is a normal good.
income elasticity measures how a good's quantity demanded responds to
change in buyers' incomes

price elasticity of demand measures
how responsive quantity demanded is to a change in price

it is perfectly elastic
the price elasticity of demand for bread is estimated at -0.40. what happens to sale revenue if the price of bread rises?
it rises
If demand is inelastic, the absolute value of the price elasticity of demand is
less than one
the larger the share of a good in a consumers budget, holding everything else constant, the
more price elastic is a consumers demand
refer to figure 6-4 the absolute value of the price elasticity of demand at the midpoint of the demand curve is
one
refer to figure 6-1. a perfectly elastic demand curve is shown in
panel B
refer to figure 6-1. the demand curve on which elasticity changes at every point is given in
panel C
the price elasticity of an upward-sloping supply curve is always
positive
If the demand for a life-saving drug was perfectly inelastic and the price doubled, the quantity demanded would
remain constant
if the cross-elasticity of demand for two goods is positive, this implies that the two goods are
substitutes
refer to figure 6-4. which of the following statements about price elasticity of demand is true?
the elastic portion of a straight-line, downward-sloping demand curve corresponds to the segment above the midpoint
suppose the demand curve for a product is represented by a typical downward-sloping curve. now suppose the demand for this product increases. which of the following statements predicts the resulting increase in price?
the more elastic the supply curve, the smaller the price increase
Which of the following statements is true?
the more narrowly we define a market, the more elastic the demand for a product will be
holding everything else constant, the demand for a good tends to be more elastic
the more substitutes there are for the good
consider a demand curve that has a constant elasticity value of 0. what happens to quantity demanded and total revenue when price increases?
the quantity demanded does not change but total revenue increases.
