A product is likely to have a price elasticity of demand that exceeds 1 when:
Its price falls
It is a necessity
It has close substitutes
Consumers are not very responsive to changes in price

X is an inferior good and is a complement to Y.
X is an inferior good and is a substitute for Y.
X is a normal good and is a complement to Y.
X is a normal good and is a substitute for Y.
Assume the income elasticity of demand for good Z equals −5.0. Which of the following is true?
