1) A decline in the price of good A causes the demand curve for good B to shift to the left. We can conclude goods A and B are

a. inferior goods

b. substitutes

c. normal goods

d. complements

2) you observe the price of a good rises and the quantity sold decreases. This is the result of

a. a decrease in supply

b. an increase in supply

c. a decrease in demand

d. an increase in demand

3) suppose people buy more of good 1 when the price of good 2 falls. These goods are

a. normal

b. inferior

c. substitutes

d. complements

Expert Solution

1. Option B.

Substitute goods are those goods which have positive cross elasticity of demand.
This means that when the price of one good rises, the demand for another good also rises. Similarly when the price of one good falls, the demand for another good also falls.
If the fall in the price of good A causes the demand curve for good B to shift to the left, it means that both A and B are substitutes of each other.

2. Option A.

When the price of a good rises, the supply decreases as there is an inverse relationship between price and supply.
Hence if the price of a good rises and the quantity sold decreases, this is the result of a decrease in supply.

3. Option D.

Complement goods are those goods with negative cross elasticity of demand.
This means that when the price of any one good Increases, the demand for another good decreases and vice versa.
Here, if the price of good 2 falls, people tend to buy more of good 1, this shows that both the goods are complements.

1. If incomes increase by 10% and this causes demand for some good to fall by 15%, then the income elasticity is ____________________ and this is a(n) _______________________ good. 2. If the elasticity of supply is 2.5, what happens when price increases by 6%? Is supply elastic or inelastic? 3. For complements, the ________________________ elasticity is always _____________________ and for substitutes it is always ______________________. 4. As more of a good is produced, the marginal cost of producing that good...

When the indifference curve with Good A on the vertical axis and Good B on the horizontal axis is tangential to the budget line, then at that point, the marginal rate of substitution of Good A for Good B is equal to the ratio of the price of Good A and Good B (PA/PB) True False The rate at which one input can be exchanged for another input without altering the level of output is called the Marginal product curve...
