Question 1

The price elasticity of demand for corn is 0.4. A new hybrid of corn is discovered and all farmers start to use it, which increases the quantity of corn they can produce from each acre. What happens to the farmers' total revenue?
A) The total revenue will increase.
B) The total revenue will decrease.
C) The total revenue will not change.
D) There is not enough information to determine what happens to the total revenue.

Accepted Answer

The price elasticity of demand for corn is inelastic (less than 1), meaning that the percentage change in quantity demanded is less than the percentage change in price. When supply increases, the price will decrease, and since demand is inelastic, the total revenue will decrease.

Question 2

Suppose Sandy's Candies wants to increase its total revenues. If Sandy increases the price of her candy, she must be assuming that the demand for candy is
A) unit elastic.
B) inelastic.
C) elastic.
D) income elastic.

The demand is inelastic because the percentage change in quantity demanded (15%) is less than the percentage change in price (20%). In such cases, total revenue decreases when the price falls.

Question 15

A university conducts a survey of students, which shows that a 10 percent tuition hike would lead to a 7 percent decrease in the enrollment. If the university wants to increase its total revenue, it should ________ tuition because the demand for education at this university is ________.
A) raise; elastic
B) not raise; elastic
C) raise; inelastic
D) not raise; inelastic

Accepted Answer

The demand is inelastic because the percentage decrease in enrollment (7%) is less than the percentage increase in tuition (10%). Raising tuition would increase total revenue since the loss in revenue from fewer students is less than the gain from higher tuition per student.

Question 16

If the demand for a good is unit elastic
