b. the good is a luxury.

c. the market is defined very broadly.

d. the time horizon is long.

2.

A perfectly elastic demand is represented graphically by a:

a. relatively steep demand curve.

b. relatively flat demand curve.

c. vertical demand curve.

d. horizontal demand curve.

3.

What effect will an increase in the price have on Total Revenue, if demand is elastic?

a. Total Revenue will increase.

b. Total Revenue will decrease.

c. Total Revenue will first decrease and then increase.

d. Total Revenue will remain unchanged.

4.

a. at points further up and to the left along the demand curve.

b. at points further down and to the right along the demand curve.

c. when the demand curve becomes steeper.

d. when the demand curve is vertical.

5.

Suppose that General Cars increases the price of its Cadiclap model from $13,500 to $16,500. As a result of this, the quantity demanded of the Cadiclap model decreases from 600,000 to 400,000 per year. Find the price elasticity of demand of the Cadiclap using the Mid-Point method.

a. -3.0

b. -0.5

c. -2.0

d. -0.3

a. drop, inelastic

b. raise, elastic

c. drop, elastic

d. drop, unit elastic

7.

a. 1.50

b. 0.67

c. -1.50

d. -0.67

8.

Suppose that a good has an income elasticity of demand of -2.0. This means that the good is:

b. inferior.

c. a substitute.

d. a complement.

9.

b. inferior.

c. substitutes.

d. complements.

10.

b. +2.0

c. +1.0

d. -2.0
