Question

Over time, technological advance increases consumers' incomes and reduces the price of smartphones. Each of these forces increases the amount consumers spend on smartphones if the income elasticity of demand is greater than ________ and if the price elasticity of demand is greater than ________.a. zero, zero
b. zero, one
c. one, zero
d. one, one

Answer 1

Answer: The correct option is C. One, zero.

Explanation:

When income elasticity is greater than one, it indicates that the quantity demanded is greater than the rise in income.

As quantity demanded increases, it will lead to a decrease in price to the extent that the percentage change in price will outweigh the percentage change in quantity demanded, meaning that the price elasticity is greater than zero.

When these two elasticities are combined, the resulting effect will be an increase in the level of consumer spending on smartphones.
