Practice Questions 4a

1) Consider the market for a particular good, where the market demand is given by P=15-(QD/20) and the market supply is given by P=QS/5. The market equilibrium price and quantity is:

a. P*=$8, Q* = 20.
b. P*=$10, Q* = 20.
c. P*=$12, Q* = 60.
d. P*=$14, Q* = 10.
e. P*=$16, Q* = 40.

2) Consider the same market as in question 1. If the government imposed a price ceiling of $10,

a. A surplus of 30 units would result.
b. A surplus of 50 units would result.
c. A shortage of 30 units would result.
d. A shortage of 50 units would result.
e. The price ceiling would have no effect on the market.

3)The market for hotdogs is characterized by demand Qd=60-2P and supply Qs=4P. Which of the following price ceilings will result in a market shortage?

a. Price ceiling of $200.
b. Price ceiling of $50.
c. Price ceiling of $10.
d. Price ceiling $5.
e. None of the above.

4)The demand curve is Qd=12-2P. The supply curve is Qs=P. In equilibrium, price elasticity of demand is (use the point elasticity formula):
a. -.5.
b. -1.
c. -1.5.
d. -2.
e. -2.5.

5)You own a lemonade stand and have observed that when you raise the price of lemonade from 10 cents to 25 cents, your total revenue doubles. Using this information, you can conclude that:

a. The demand for lemonade is elastic.
b. The demand for lemonade is inelastic.
