Q: What is the formula for calculating consumer surplus in a market?

$$CS = \frac{1}{2} \times (Q^*) \times (P_{max} - P^*)$$

Question 1

Suppose the government imposes a price ceiling on gasoline at $$0.57 per gallon, while the equilibrium price is 1.50 $$per gallon. What is the most likely immediate effect in the market?

Accepted Answer

A shortage of gasoline will occur, as quantity demanded will exceed quantity supplied.

Question 2

Which of the following best describes 'consumer surplus'?

Accepted Answer

The difference between the maximum amount a consumer is willing to pay and the market price.

Question 3

If the supply of wheat shifts to the left due to a natural disaster, what happens to the equilibrium price and quantity in the wheat market?

Accepted Answer

Equilibrium price rises and equilibrium quantity falls.

Question 4

A price floor is set above the equilibrium price in the labor market. What is the most likely outcome?

Accepted Answer

A surplus of labor, resulting in unemployment.

Question 5

Which of the following is an example of a nonprice rationing mechanism?

Accepted Answer

Queuing, or waiting in line for goods.

Question 6

Suppose the government imposes a tariff on imported oil, raising the domestic price from $$80 to 106.64 $$per barrel. What is the most likely effect on domestic production and imports?

Accepted Answer

Domestic production increases and imports decrease.

Question 7

What is the formula for calculating consumer surplus in a market?

Accepted Answer

$$CS = \frac{1}{2} 	imes (Q^*) 	imes (P_{max} - P^*)$$

Question 8

Which of the following best explains why black markets may arise when a price ceiling is imposed?

Accepted Answer

Because the legal price is set below equilibrium, creating a shortage and unmet demand.

Question 9

If a concert ticket is sold at a face value of $$50 but the equilibrium price is 300$$, what is the likely result?

Accepted Answer

There will be excess demand, leading to alternative rationing mechanisms.

Question 10

What is 'deadweight loss' in the context of market efficiency?

Accepted Answer

The total loss of producer and consumer surplus from underproduction or overproduction.

Question 11

Which of the following is most likely to cause a deadweight loss in a competitive market?

Accepted Answer

Imposing a price ceiling or price floor.

Question 12

If the government issues ration coupons for gasoline during a shortage, what is the intended effect?

Accepted Answer

To ensure each individual can purchase a limited amount of gasoline.

Question 13

Which of the following best describes 'producer surplus'?

Accepted Answer

The difference between the market price and the cost of production for the firm.

Question 14

Suppose a market is in equilibrium. If a price floor is imposed above the equilibrium price, what will happen to consumer and producer surplus?

Accepted Answer

Consumer surplus will decrease and producer surplus may increase or decrease, but total surplus will fall due to deadweight loss.

Question 15

Which of the following is NOT a likely consequence of bypassing price rationing with alternative mechanisms?

Accepted Answer

The allocation of goods becomes more efficient.

Question 16

A minimum wage is an example of which of the following?

Accepted Answer

A price floor.

Question 17

If the market for used cars experiences a supply shock due to a shortage of semiconductor chips, what is the most likely effect on the price of used cars?

Accepted Answer

The price of used cars will increase due to higher demand.

Question 18

Which of the following equations represents the deadweight loss from underproduction in a market?

Accepted Answer

$$DWL = \frac{1}{2} 	imes (Q^* - Q_1$) 	imes (P_D - P_S)$$

Question 19

Which of the following is a potential source of market failure?

Accepted Answer

Monopoly power leading to underproduction and overpricing.

Question 20

If a museum offers free admission on a weekday and observes more senior citizens attending, what economic concept best explains this outcome?
