Document Summary

Price control law= a law that mandates what price buyers and sellers must trade at. Price always moving towards market clearing price floor is above equilibrium bc that"s were price wants to fall. Ceiling has to be below equilibrium bc that"s where price wants to rise. Cost-benefit analysis of maximum price control laws: producer surplus = area bw supply and price, if price is lower, shrinks producer surplus and quantity. Consumer surplus is trapezoid (green)- consumer supply decreases surplus. Maximum price control: benefit some consumers and harm others, harm other producers, do more harm than good harm exceeds benefits. Minimum price control: push prices up, consumers will be worse off so shrinks consumer surplus, also harms producers bc when you produce price up, quantity demanded will decrease which limits the quanity that gets exchanged. Producer surplus is trapezoid limited by quantity demanded line.

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 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.

Suppose that the demand and supply schedules for rental apartments in the city of Gotham are as given in the table below.

Monthly Rent	Apartments Demanded	Apartments Supplied
$2500	10,000	15,000
2000	12,500	12,500
1500	15,000	10,000
1000	17,500	7500
500	20,000	5000

a. What is the market equilibrium rental price per month and the market equilibrium number of apartments demanded and supplied?

b. If the local government can enforce a rent-control law that sets the maximum monthly rent at $1500, will there be a surplus or a shortage? Of how many units? And how many units will actually be rented each month?

c. Suppose that a new government is elected that wants to keep out the poor. It declares that the minimum rent that can be charged is $2500 per month. If the government can enforce that price floor, will there be a surplus or a shortage? Of how many units? And how many units will actually be rented each month?

4. Suppose that the government wishes to decrease the market equilibrium monthly rent by increasing the supply of housing. Assuming that demand remains unchanged, by how many units of housing would the government have to increase the supply of housing to get the market equilibrium rental price to fall to $1500 per month? To $1000 per month? To $500 per month?
