Question 1

Price floors and ceiling prices both

Accepted Answer

Price floors and ceiling prices interfere with the rationing function of prices, meaning they prevent the equilibrium price and quantity from being established by the market forces of supply and demand. This interference can lead to distorted market outcomes, such as surpluses or shortages.

Question 2

Suppose that in the clothing market, production costs have fallen, but the equilibrium price and quantity purchased have both increased.Based on this information we can conclude that

Accepted Answer

The decrease in production costs has led to an increase in the supply of clothing, which would typically lead to a decrease in equilibrium price and an increase in equilibrium quantity (according to the law of supply and demand). However, since the equilibrium price and quantity have both increased, this suggests that the increase in demand for clothing has outpaced the increase in supply, resulting in a higher equilibrium price and quantity. Therefore, demand for clothing has grown faster than the supply of clothing.

Question 3

Black markets are associated with

Accepted Answer

Black markets are typically created as a result of government-imposed ceiling prices, which create a shortage of the product in the legal market. As a result, suppliers turn to the black market to sell their goods at a higher price, which then creates an illegal market.

Question 5

(Advanced analysis) The demand for commodity X is represented by the equation P = 100 - 2Q and supply by the equation P = 10 + 4Q.The equilibrium price is

Accepted Answer

To find the equilibrium price, we need to set the demand and supply equations equal to each other and solve for P:
100 - 2Q = 10 + 4Q
90 = 6Q
Q = 15
Now that we know the equilibrium quantity is 15, we can plug that into either the demand or supply equation to solve for P:
P = 100 - 2Q
P = 100 - 2(15)
P = 70
Therefore, the equilibrium price is $70, which is answer choice B.

Question 6

(Advanced analysis) The demand for commodity X is represented by the equation P = 10 - 0.2Q and supply by the equation P = 2 + 0.2Q.The equilibrium price for X is

Accepted Answer

To find the equilibrium price for commodity X, we need to find the point where demand equals supply. Setting the two equations equal to each other, we have:

10 - 0.2Q = 2 + 0.2Q

Solving for Q, we get Q = 20. Plugging this value back into either equation, we can find the equilibrium price:

P = 10 - 0.2(20) = 6

Therefore, the equilibrium price for commodity X is $6, which corresponds to choice C.

Question 7

(Advanced analysis) The demand for commodity X is represented by the equation P = 100 - 2Q and supply by the equation P = 10 + 4Q.If demand changed from P = 100 - 2Q to P = 130 - Q, the new equilibrium price is

Accepted Answer

We can find the original equilibrium price and quantity by setting the demand equal to the supply:

100 - 2Q = 10 + 4Q
90 = 6Q
Q = 15

P = 100 - 2(15)
P = 70

So the original equilibrium price is $70. Now we can use the new demand equation to find the new equilibrium price:

130 - Q = 10 + 4Q
120 = 5Q
Q = 24

P = 130 - 24
P = 106

So the new equilibrium price is $106. Therefore, the best choice is D.

Question 8

An effective price ceiling will

Accepted Answer

An effective price ceiling is a government-imposed limit on the maximum price that can be charged for a product or service. It is set below the equilibrium price, which creates a shortage of the product as the quantity supplied decreases and the quantity demanded increases. As a result, consumers may not be able to purchase as much of the product as they want or need, which can lead to rationing or black markets. Therefore, an effective price ceiling will result in a product shortage.

Question 9

A price ceiling means that

Accepted Answer

A price ceiling is a government-imposed price control that sets a legal maximum price for a product, typically below the equilibrium price. It is used to protect consumers from high prices, but can lead to shortages and rationing of the product.

Question 10

(Advanced analysis) The demand for commodity X is represented by the equation P = 10 - 0.2Q and supply by the equation P = 2 + 0.2Q.If demand changes from P = 10 - .2Q to P = 7 - .3Q, the new equilibrium quantity is

Question 12

(Advanced analysis) The demand for commodity X is represented by the equation P = 100 - 2Q and supply by the equation P = 10 + 4Q.The equilibrium quantity is

Accepted Answer

To find the equilibrium quantity, we need to set the demand equal to the supply.

100 - 2Q = 10 + 4Q

Simplifying, we get:

90 = 6Q

Q = 15

Therefore, the equilibrium quantity is 15.

Question 13

If a legal ceiling price is set above the equilibrium price,

Accepted Answer

When a legal ceiling price is set above the equilibrium price, it does not affect the market because the market can naturally settle at the equilibrium price, which is lower than the ceiling. This means transactions can occur without any interference from the ceiling price, leaving both the equilibrium price and quantity unchanged.

Question 14

(Advanced analysis) The demand for commodity X is represented by the equation P = 100 - 2Q and supply by the equation P = 10 + 4Q.If demand changes from P = 100 - 2Q to P = 130 - Q, the new equilibrium quantity is

Accepted Answer

To find the equilibrium quantity, we need to set the demand equal to the supply and solve for Q:

100 - 2Q = 10 + 4Q  (Original demand and supply)
Add 2Q to both sides:
100 = 10 + 6Q 
Subtract 10 from both sides:
90 = 6Q 
Divide both sides by 6:
Q = 15

So the original equilibrium quantity is 15.

Next, we need to find the new equilibrium quantity with the new demand equation P = 130 - Q:

130 - Q = 10 + 4Q  (New demand and original supply)
Add Q to both sides:
130 = 10 + 5Q
Subtract 10 from both sides:
120 = 5Q 
Divide both sides by 5:
Q = 24

So the new equilibrium quantity is 24.

Question 15

Which of the following is a consequence of rent controls established to keep housing affordable for the poor?

Accepted Answer

Rent controls can have multiple consequences, including reducing the amount of available rental housing, causing landlords to lack the funds and incentive to maintain properties, and leading to a shift in development away from rental properties and towards other types of buildings that are not subject to controls. Therefore, all of these options are valid consequences of rent controls.

Question 16

An effective price floor on wheat will

Accepted Answer

An effective price floor on wheat would set the price above the equilibrium price, causing a surplus of wheat as the quantity supplied exceeds the quantity demanded. This surplus would continue to grow as long as the price floor remains in place, creating a situation where the surplus cannot be sold and therefore, farmers would be forced to store the wheat or dispose of it. This could lead to increased storage costs and waste. Therefore, a price floor on wheat will result in a surplus of wheat.

Question 17

(Advanced analysis) The demand for commodity X is represented by the equation P = 10 - 0.2Q and supply by the equation P = 2 + 0.2Q.If demand changes from P = 10 - .2Q to P = 7 - .3Q, the new equilibrium price is

Accepted Answer

The answer of (Advanced analysis) The demand for commodity X...

Question 18

Over time, the equilibrium price of a gigabyte of computer memory has fallen, while the equilibrium quantity purchased has increased.Based on this we can conclude that

Accepted Answer

The equilibrium price of a good falls when the supply curve shifts to the right, meaning there is more supply available at each price. The equilibrium quantity purchased increases when there is a shift in the demand curve to the right. Therefore, the fact that the equilibrium price has fallen while the equilibrium quantity has increased implies that the supply of computer memory has increased more than demand. This indicates that increases in the supply of computer memory have exceeded increases in demand. Thus, the best choice is D.

Question 19

A price floor means that

Accepted Answer

A price floor is a government-imposed minimum legal price that is typically set above the equilibrium price. Its purpose may be to increase the income of certain producers, such as farmers or minimum wage workers, by ensuring they can sell their goods or labor at a higher price. If the price floor is set too high, it may result in a surplus of goods and a decrease in demand, leading to inefficiencies in the market.

Question 20

(Advanced analysis) The demand for commodity X is represented by the equation P = 10 - 0.2Q and supply by the equation P = 2 + 0.2Q.If demand changes from P = 10 - .2Q to P = 7 - .3Q, we can conclude that

Accepted Answer

The change in demand is from P = 10 - 0.2Q to P = 7 - 0.3Q. This represents a decrease in demand because the negative coefficient of Q has increased in magnitude. This decrease in demand would lead to a decrease in equilibrium quantity and price. The information given does not allow us to make any conclusions about changes in supply.
