Document Summary

Introduction: here we assume that the market is efficient in the absence of government intervention (that is, the market is a competitive market). Governments sometimes set a minimum price, known as a price floor. When a government puts in place a price ceiling, it sets a maximum price at which a good or service may be traded. This raises the question of how the existing units of the good should be allocated to customers. There are several ways this issue of allocation might be addressed: queuing. For example, there could be a first-come, first-served rule, which often results in queues. Consumers who are willing to wait receive the good: discrimination. A government official might pick which consumers get the good. This can be problematic if the good is distributed on the basis of nepotism rather than who values the good the most: side payments.

Question 1

During a crisis such as Hurricane Katrina, governments often make it illegal to raise the price of emergency items like flashlights and bottled water. In practice, this means that these items get sold on a first-come, first-served basis. If a person has a flashlight that she values at $5, but its price on the black market is $40, what gains from trade are lost if the government shuts down the black market?

		$30
		$35
		$40
		Indeterminant with the given information.

Question 5

What is a price ceiling?

		A minimum price consumers are willing to pay.

Question 6

Why are the long lines generated by a shortage worse than paying a higher price in money?

		It is not better or worse. Paying in time and paying in money are essentially the same in a market economy.
		Paying with time reduces the value of money, and prevents valuable trades from occurring.
		Waiting in line is a waste of a valuable resource: time. Paying a price in money transfers the value of resources from one person to another, and maximizes the value of resources.
		Paying with time gives those who do not work an advantage over those who do.

Question 7

Which of the following is a possible effect of a price floor?

		The quantity supplied exceeds the quantity demanded.
		Increased gains from trade.
		Decreases in product quality.
		A shortage of the good.

1. Using diagrams, show what changes in price and quantity would be expected in the following markets under the scenarios given. Also, say whether this represents a change in demand or a change in quantity demanded.

(a) Natural Gas: Fracking technology is improved allowing easier access to natural gas reserves.

(b) Rice: Reports surface about traces of arsenic (a poison) in rice.

(d) Soy sauce (complement to rice): Reports surface about traces of arsenic (a poison) in rice.

(e) Clothing: Labor costs for clothing manufacturers increase.

2. The market for soda has supply and demand curves given by

P = 0.02Qs
P =3?0.01Qd

(a) Graph the demand and supply curves.

(b) What is the equilibrium price and quantity for sodas?

(c) How many units of soda will be traded if the government imposes a price floor of $2.50? What about if the government imposes a price ceiling of $0.80?

3. Returning to question 2, suppose the government put a tax on soda of $0.50 per can to be paid by consumers. Graph the before and after-tax supply and demand curves. What are the new equilibrium price and quantity?
