C. more elastic the demand for the product.?
D. more inelastic the demand for the product.

3. The concept of price elasticity of demand measures: ?

A. demand is elastic.?
B. demand is inelastic.?
C. demand is of unit elasticity.?
D. not enough information is given to make a statement about elasticity.

5. When the percentage change in price is greater than the resulting percentage change in quantity demanded: ?
A. a decrease in price will increase total revenue.?
B. demand may be either elastic or inelastic.?
C. an increase in price will increase total revenue.?
D. demand is elastic.

6. In which of the following cases will total revenue increase? ?
A. price falls and demand is inelastic?
B. price falls and supply is elastic?
C. price rises and demand is inelastic?
D. price rises and demand is elastic

7. The coefficient of price elasticity is 0.2. Demand is thus: ?
A. perfectly inelastic.?
B. perfectly elastic.?
C. relatively inelastic.?
D. relatively elastic.

8. The main determinant of elasticity of supply is the: ?
A. number of close substitutes for the product available to consumers.?
B. amount of time the producer has to adjust inputs in response to a price change.?
C. urgency of consumer wants for the product.?
D. number of uses for the product.

9. We would expect the cross elasticity of demand between Pepsi and Coke to be: ?
A. positive, indicating normal goods.?
B. positive, indicating inferior goods.?
C. positive, indicating substitute goods.?
D. negative, indicating substitute goods.

10. Consumer surplus: ?
A. is the difference between the maximum prices consumers are willing to pay for a product and the lower equilibrium price.?
B. the difference between the maximum prices consumers are willing to pay for a product and the minimum prices producers are willing to accept.?
C. the difference between the minimum prices producers are willing to accept for a product and the higher equilibrium price.?
D. rises as equilibrium price rises.

11. Marginal utility can be: ?
A. positive, but not negative.?
B. positive or negative, but not zero.?
C. positive, negative, or zero.?
D. decreasing, but not negative.

12. The law of diminishing marginal utility states that: ?
A. total utility is maximized when consumers obtain the same amount of utility per unit of each product consumed.?
B. beyond some point additional units of a product will yield less and less extra satisfaction to a consumer.?
C. price must be lowered to induce firms to supply more of a product.?
D. it will take larger and larger amounts of resources beyond some point to produce successive units of a product.

13. The first Pepsi yields Craig 18 units of utility and the second yields him an additional 12 units of utility. His total utility from three Pepsis is 38 units of utility. The marginal utility of the third Pepsi is: ?
A. 26 units of utility.?
B. 6 units of utility.?
C. 8 units of utility.?
D. 38 units of utility.
