Check Your Understanding 4-1 Question 1
Homeowners near Middletown University’s stadium used to rent parking spaces in their driveways to fans at a going rate of \$11. A new town ordinance now sets a maximum parking fee of \$7. Use the accompanying supply and demand diagram to answer the following questions.

1a) Given the new price of \$7 some homeowners now think it’s not worth the hassle to rent out spaces. This causes: The decrease in price from \$11 to \$7 causes a decrease in quantity supplied of 400, from 4000 to 3600. supply to shift left. quantity decreases along the supply curve.

quantity demanded increases along the demand curve.
1b) Some fans that used to carpool drive to the game alone because of the lower price of parking. This causes: The decrease in price causes an increase in quantity demanded of 400, from 4000 to 4400. demand to shift right. quantity demanded increases along the demand curve.

1c) Given the maximum parking fee of \$7, based on questions a and b you would expect there to be a ________ of parking spaces. shortage surplus perfect number At \$7, the quantity demanded is 4400 and the quantity supplied is 3600, so there is a shortage of 800 parking spaces.

Check Your Understanding 4-1 Question 2

2a) Compared to the free market, price ceilings at a price below the equilibrium price increase quantity supplied. True False Price ceilings decrease the quantity supplied and increase the quantity demanded.

2b) Compared to the free market, price ceilings at a price below the equilibrium price make some people who want to consume the good worse off. True False Because the quantity supplied has decreased, some people who are willing to pay the higher equilibrium price are not able to buy the good.

2c) Compared to the free market, price ceilings at a price below the equilibrium price make all producers worse off. True False A lower price reduces producer surplus, the difference between the price of the product and its cost, shown by the supply curve.

Income will increase for all gas station owners.
1a) Which of the following is true about the law mandating the price floor? Income for the station owners who sell QF at price PF will benefit from higher incomes. However, the incomes of those who had made sales QE at the equilibrium price PE have lower incomes. Income will increase for all gas station owners. Income will decrease for all gas station owners. Income will increase for some gas station owners and decrease for others. Income will remain unchanged for all gas station owners.

inefficiently high quality. wasted resources.
1b) Some argue that the price floor is a good idea because it will lead to better service at gas stations. This is an example of ________.

Check Your Understanding 4-3 Question 1
The government has enacted a quota on taxicab rides of 6 million rides per year. Use the information about supply and demand given below to answer the following questions.

1a) With a quota of 6 million, what is the price of a ride?
\$3 \$4 \$5 \$6 \$7 The demand price for 6 million rides is \$7.

1b) With a quota of 6 million, what is the quota rent?
\$3 \$4 \$5 \$6 \$7 The quota rent is \$4, the difference between the demand price of \$7 and the supply price of \$3 at the 6 million rides that the quota allows.

1c) Suppose the quota limit on taxi rides increased to 9 million
1c) Suppose the quota limit on taxi rides increased to 9 million. What would the quota rent be? \$1 \$2 \$3 \$4 The quota rent is the difference between the demand price of \$5.50 at 9 million and the supply price of \$4.50 at 9 million.
