Question

When the price of a

skateboard

increases by

4

percent, the quantity of

elbow pads

demanded decreases by

1

percent.

Calculate the cross elasticity of demand for

elbow pads

with respect to the price of a

skateboard.

Answer #1

Cross elasticity of demand measure the degree of responsiveness
of quantity demanded of one related good to a change in the price
of another related good.

Cross elasticity = %change in quantity demanded of one related good
/ %change in the price of another related good.

In the question,

% Increase in the price of skateboard is 4% and

% Decrease in the quantity demanded elbow pads is 1%

Cross Elasticity = -1% / 4%

Cross Elasticity = -0.25

As the cross elasticity is negative, the goods are complementary.

A measure of the rate of percentage change of quantity demanded
with respect to price, holding all other determinants of demand
constant is
a.
Income elasticity of demand
b.
Own price elasticity of demand
c.
Price elasticity of market equilibrium
d.
Cross price elasticity of demand
The value of the income elasticity of demand coefficient for
Good X is given as 0.1. This means that
a.

percent.
b.
as income...

When the price of good "X" increases 20 percent (+20%), Harry
decreases his quantity demanded of "X" by 25 percent while Meghan
decreases her quantity demanded of "X" by 15 percent. Harry's
demand for good "X" is (relatively inelastic / unitary elastic /
relatively elastic) and Meghan's demand for good "X" is (relatively
inelastic / unitary elastic / relatively elastic).
A. Relatively inelastic; relatively
inelastic.
B. Relatively inelastic; relatively
elastic.
C. Unitary elastic; relatively
elastic.
D. Relatively elastic; relatively
elastic.

demanded decreases; and, as price decreases, quantity demanded
increases? If taxes were more progressive, would total output be
affected?
